The weather was sultry and humid after entering the night.For this reason, it can be speculated that hvac split systems The market feedback will get better and better, which is one of the important reasons why it can develop. https://puremind.com/product-category/puremind-air-conditioner/split-air-conditioner/
The frequency of air conditioning is increasing.
Hot summer day
Is it advisable to stay in an air-conditioned room for a long time?
Do I need to open the window to ventilate the air conditioner?
The answer is coming ◎
Turning on the air conditioner should not close the doors and windows.
A set of experiments will show you.
Many people have been in air-conditioned rooms for a long time.
I will feel dizzy and sleepy.
This may be that the indoor carbon dioxide concentration exceeds the standard.
Experts said
National standard of indoor carbon dioxide concentration
The general requirement is below 1000ppm.
For shopping malls, schools and other densely populated places
Generally, the concentration of carbon dioxide is required to be below 1500ppm.
When the indoor carbon dioxide concentration reaches 2000ppm
The human body often feels dizzy and uncomfortable.
There are only two or three people in the family.
Why does the concentration of carbon dioxide exceed the standard?
Two experimenters are in a 13-square-meter bedroom
Close the doors and windows and turn on the air conditioner.
By placing a good observer
Real-time observation of indoor carbon dioxide concentration changes
Over time
The concentration of carbon dioxide keeps rising.
Just half an hour.
It has already exceeded 1500ppm.
Experts said
For the home environment
This concentration has exceeded the standard
after an hour
The concentration of carbon dioxide in the air
More than 2000ppm
And it’s rising
The experimenter opened the window for ventilation.
After 15 minutes.
Indoor carbon dioxide concentration
Slowly dropped below 1000ppm.
It can be seen that the doors and windows are closed and the air conditioner is turned on for 1 hour.
It may cause the indoor carbon dioxide concentration to exceed the standard.
If you sleep in this environment for one night,
It is very likely that lack of oxygen will bring health risks.
It is recommended to turn on the air conditioner.
Open the window properly to get some air.
For families that are inconvenient to open windows
Consider purchasing a new fan.
Instead of window ventilation
Air-conditioned rooms should not stay long.
Beware of “air conditioning disease”
It is hot and hot in summer.
Stay in an air-conditioned room for a long time
Not only dizziness, headache
It may also induce “air conditioning disease”
Knowledge of small science popularization
”Air-conditioning disease” is a series of diseases induced by long-term use of air conditioning. When using air conditioning, the space is relatively closed, the air is not circulating, pathogenic microorganisms are easy to breed, and the temperature difference between indoor and outdoor is large, so the body is not well adapted, so a series of symptoms will appear.
Abdominal pain and diarrhea
The stomach and intestines are very sensitive to the stimulation of temperature.
Excessive indoor and outdoor temperature difference
Accelerated gastrointestinal peristalsis
Cause digestive dysfunction
Cause abdominal pain and diarrhea
catch a cold and have a fever
Enter the room with low temperature from the hot outdoor.
Easy to catch a cold and cough.
Even induce asthma and pneumonia.
Serious illness
neck shoulder lumbocrural pain
Thin clothes in summer
Shoulder, knee, waist, etc.
Exposed to the cool breeze for a long time
It is easy to cause symptoms such as joint and muscle pain.
It is easy to cause cervical spondylosis and scapulohumeral periarthritis.
cardiac infarction
From low temperature indoor to high temperature outdoor.
Switch like this
Will make blood vessels suddenly contract and expand.
Repeated fluctuation of blood pressure may induce myocardial infarction.
For the elderly with fragile blood vessels,
be highly dangerous
How to blow air conditioning healthily?
Pay attention to these points!
Air conditioning should be cleaned regularly.
Whether it’s central air conditioning
Or a stand-alone air conditioner at home
It should be cleaned before use.
It is recommended to clean it once every 1~2 months after use.
Window ventilation is essential.
Turn on the air conditioner
Attention should be paid to frequent ventilation.
It is recommended that every 2~3 hours.
Just ventilate the room once.
Ventilation for 10 to 15 minutes each time.
Air conditioning wind blows upward.
The temperature should not be too low.
Cold air will stimulate sweat pores to contract suddenly.
It is easy to cause dizziness, headache, runny nose,
Symptoms such as joint pain.
It is suggested that the temperature of air conditioner should be adjusted to 26≧
The temperature difference between indoor and outdoor should not exceed 7≧
When the air conditioner is turned on, the cold air sinks.
So the wind had better blow upward.
Avoid cold air blowing directly on your body.
Drink more warm water.
To prevent water loss from the body
Causes dry skin and itchy throat.
Drink plenty of warm water.
Drink chrysanthemum tea, etc
Eat more fresh fruits rich in vitamins.
Improper use of air conditioningIn order to facilitate users to have a better experience, truck air conditioner Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. https://puremind.com/product-category/puremind-air-conditioner/rv-air-conditioner/
Not only will it increase electricity consumption,
It may even affect your health.
Today, follow the Shanghai Health Promotion Center.
Let’s learn the “cold knowledge” of air conditioning use ~
Don’t “open and close for a while”
I wonder if you have had such an experience?
Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.
In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.
Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.
Pay attention to “humidity” and “temperature”
The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.
If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.
Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.
Don’t sweat and rush into the air-conditioned room.
In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.
For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.
The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.
Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.
Do a good job cleaning
The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”
Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.
The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.
In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.
Improper use of air conditioningbeyond doubt chilled water system It will definitely lead the development direction of the whole industry and let its light bloom in this field. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

What is a fixed-frequency air conditioner? The grid voltage in China is 220 volts and 50 hertz, and the air conditioner working under this condition is called a fixed-frequency air conditioner. Because the power supply frequency can’t be changed, the rotating speed of the compressor of the traditional fixed frequency air conditioner is basically unchanged, and the indoor temperature can be adjusted by constantly “turning on and off” the compressor, which is easy to cause the room temperature to be hot and cold and consume more electricity.This means that inverter hvac system It is the weather vane of the industry and can bring people great self-confidence. https://puremind.com/product-category/puremind-air-conditioner/split-air-conditioner/
What is a variable frequency air conditioner? The main engine of the variable frequency air conditioner automatically performs stepless speed change, and it can automatically provide the required cooling (heating) amount according to the room conditions. When the indoor temperature reaches the expected value, the air conditioning main engine will run at a constant speed that can accurately maintain this temperature, so as to realize “non-stop operation”, thus ensuring the stability of the environmental temperature.
Advantages and disadvantages analysis:
Advantages of fixed frequency air conditioning: affordable price, more options, rich products and various types.
Disadvantages of fixed frequency air conditioning: Relative temperature control and energy saving are still slightly inferior to frequency conversion.
Advantages of inverter air conditioner: more accurate temperature control, low temperature, wide voltage start, and more energy saving.
Disadvantages of inverter air conditioner: the relative price positioning is higher, while the affordable inverter is less optional.
To sum up, it is obvious that inverter air conditioners are smarter! But the price will naturally be more expensive.
Winter is coming, and many friends in the south are estimated to be inseparable from the company of air conditioning. Recently, some netizens who are familiar with the home appliance industry have summed up 10 cold knowledge about air-conditioning electric auxiliary heating. If you are afraid of cold, you may be able to learn it.Sufficient data show that Puremind RV Air Conditioners It can drive many people to find jobs, thus driving economic development. https://puremind.com/puremind-hot-sale/
1. 38≧: According to the standard, the air outlet temperature should reach above 38≧ when air conditioning is heating, which is higher than human body temperature, otherwise it will feel like cold air when blowing on people.
2, wind speed: air conditioning heating, high wind speed when the outlet temperature is low, low wind speed when the outlet temperature is high.
3. Temperature: After the air conditioner is turned on for heating, the air outlet temperature of 40≧ is faster than that of 60≧. Because the hot air floats up, the high temperature of the outlet air will float up to the roof faster, and the lower temperature will help the middle and lower air to heat up.
Comprehensive 2 and 3, if the air conditioner wants to heat well, it needs to turn on the large air volume, and after turning it on, the air will be discharged at 40≧ first, and then the air will be heated to about 50≧ after the room temperature rises.
4. The purpose of electric auxiliary heat: it is to heat the air outlet temperature. When the outdoor temperature decreases, the heating performance of the air conditioner will be attenuated. Turning on electric auxiliary heat can increase the air outlet temperature and avoid people feeling cold wind blowing.
5. When do you need to turn on the auxiliary heating? According to the national standard, when the outdoor temperature is above 0≧, the auxiliary heating of air conditioner is turned off by default, and users can turn it on manually. When the temperature is lower than 0≧, it is turned on by default, and the user can turn it off manually.
6. Principle of electric auxiliary heating: The electric auxiliary heating is at the lower end of the internal heat exchanger, in front of the air outlet of the air conditioner, with PTC ceramic heating rods inside and aluminum fins outside. After electric auxiliary heating, the temperature will reach 200~300≧, so electric auxiliary heating can’t be dry-burned, and the air conditioner must be blown after it is turned on.
7. Will electric auxiliary heating blow white powder? The consultant learned that in 2024, the air-conditioning models were sold, and the sleeve pieces had been passivated, or Teflon coating was sprayed on the surface to prevent white powder blowing. At present, the models on sale will not have the problem of blowing white powder.
8. When defrosting the air conditioner, can you turn on the electric auxiliary heat to avoid excessive cooling of the room?
No way. When the air conditioner is defrosting, the internal fan stops running, and the air conditioner does not give out air. If the electric auxiliary heat is turned on, it will dry up and may burn out the internal machine parts. When the air conditioner is defrosting, it is not good for the internal machine to keep blowing air.
9. Air conditioners that do not stop defrosting. When some models defrost, the internal heat exchanger will heat up. Is the electric auxiliary heating turned on?
No, electric auxiliary heating can only heat the outlet air temperature, but not the heat exchanger.
10. Japanese air conditioners are good at heating without electricity, but domestic air conditioners are not good at heating with electricity.
There are many kinds of refrigeration methods, such as gas expansion refrigeration, liquid gasification refrigeration, vortex tube refrigeration and thermoelectric refrigeration. Among them, liquid gasification refrigeration is the most widely used, and its working principle is to realize refrigeration by using the heat absorption of liquid gasification.For the immediate pressure, solar powered hvac With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://puremind.com/product-category/puremind-air-conditioner/solar-air-conditioner/
1, the working principle of air conditioning (mainly refrigeration, heating on the contrary):
The high-temperature and high-pressure refrigerant discharged from the compressor flows through the outdoor heat exchanger through the four-way valve, and dissipates heat to the outdoor air through heating transfer, and the refrigerant changes from gaseous state to liquid state-throttles and depressurizes through capillary (or solenoid valve)-one-way valve-filter-two-way valve (outdoor high-pressure pipe)-enters the indoor heat exchanger to absorb heat (realize refrigeration)-outdoor three-way valve (outdoor low-pressure pipe). Complete a single-loop refrigeration cycle.
2. Types of components in refrigeration system:
The air conditioning refrigeration system is mainly composed of four parts and some auxiliary equipment in the refrigeration system.
The four major pieces are:
compressor
condenser
Throttle mechanism
Evaporator composition.
Auxiliary equipment:
Oil separator;
Drying filter;
Liquid storage tank;
Electromagnetic four-way reversing valve;
Solenoid valve; Check valve
3, the working principle of each component
Compressor: As the “heart” of refrigeration system, it has an important influence on the performance, noise, energy consumption, vibration and service life of air conditioning. According to the principle of thermodynamics, it can be divided into volumetric type and velocity type.
Volumetric type: a certain volume of gas is sucked into the cylinder and the internal volume of the cylinder is changed to realize gas compression and forced discharge.
Speed type: make the inhaled gas get a certain speed, and then slow down, so that kinetic energy can be converted into pressure energy and then discharged. The growth of gas is converted from speed.
one
Scroll compressor: It is formed by meshing two vortexes of stator and rotor.
Rotor compressor: it consists of spindle with eccentric wheel, cylinder, sleeve, air inlet, slide plate, spring, exhaust valve and exhaust port.
Condenser: The condenser transfers the refrigerating capacity of the evaporator in the refrigeration system to the environmental medium (cooling water or air) together with the power consumption of the compressor. According to cooling, it can be divided into air-cooled type, water-cooled type and evaporative type. When cooling, it mainly radiates heat to the outside, and when heating, it absorbs heat to the outside.
Evaporator: The main function of the evaporator is to boil and evaporate the low-temperature and low-pressure refrigerant liquid that has entered the throttle in the evaporator, absorb the heat of the cooled medium, and then become low-pressure saturated (usually overheated) vapor itself, which is continuously sucked away by the compressor. In other words, the evaporator is a heat exchange device that absorbs heat (that is, outputs cold energy).
Throttle element: Throttle element is one of the four main elements in the refrigeration system. Its main function is to throttle and reduce the pressure of high-pressure liquid refrigerant, ensure the pressure difference between condenser and evaporator, and make the refrigerant entering the evaporator absorb heat and evaporate at the required low pressure, thus achieving the purpose of refrigeration and cooling. Adjust the refrigerant flow into the evaporator to adapt to the load change of the evaporator and make the system run normally.
Capillary: It is a very thin tube, usually with an inner diameter of 0.5 ~ 2.5 mm and a length of 1 ~ 5 m.. When the refrigerant flows in the tube, it is necessary to overcome the resistance in the tube, which naturally produces a certain pressure drop.
Capillary characteristics: Because it is in the normally open state, when the compressor stops, the high and low pressure can be quickly balanced, which is conducive to the compressor starting again. Simple structure, convenient manufacture and low price. For the heat pump system, there is no import and export problem in the throttling process of refrigerant in capillary [this article source: refrigeration encyclopedia WeChat official account” target=_blank>. Using capillary refrigeration system, the performance of the unit is very sensitive to the refrigerant charge. When the operating conditions of the refrigeration system change, the capillary tube has poor ability to adjust the refrigerant flow. Due to the small inner diameter of capillary and long pipeline, it is easy to be blocked, so attention should be paid to the drying and cleaning of the system. Generally, a dry filter is set in front of the capillary to prevent clogging.
Thermal expansion valve: the regulating valve that controls the liquid supply of evaporator, and it is also the throttle valve of refrigeration device. Thermal expansion valve uses the change of superheat of refrigerant at evaporator outlet to adjust the flow. According to different structures, it can be divided into internal balance type and external balance type.
Disadvantages of thermal expansion valve: low control precision and limited adjustment range. The diaphragm deformation of valve body is limited, which makes the change range of valve needle opening smaller, so the adjustment range of flow is small. When large flow regulation is required, it cannot be met. The high-temperature gas at the place where the signal feedback has a lag evaporator must first heat the shell of the temperature sensor, which has a large thermal inertia, leading to the lag of the reaction.
2
Electronic expansion valve: the application of electronic expansion valve overcomes the shortcomings of thermal expansion valve and provides conditions for the intelligence of refrigeration device. The electric signal generated by adjusting parameters is mainly used to control the voltage or current applied to the expansion valve, so as to achieve the purpose of adjustment, so that the control system of the electronic expansion valve is complicated and the price is high.
Electronic expansion valve classification:
Electromagnetic electronic expansion valve;
Electric electronic expansion valve.
4. Auxiliary equipment of refrigeration system
Oil separator: The high-pressure gas (gaseous working medium and lubricating oil) from the compressor enters the oil separator to separate the lubricating oil from the working medium gas and flows down along the inner wall of the cylinder. The working gas is led out of the oil separator from the central pipe through the porous baffle. The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged regularly, or the lubricating oil can be automatically returned to the crankcase of the compressor by using the ball valve.
Drying filter: The function of drying filter is to absorb moisture in refrigeration system, prevent impurities in the system from passing through, and prevent the pipeline of refrigeration system from being blocked by ice and dirt. Because the most easily blocked part of the system is the capillary (or expansion valve), the drying filter is usually installed between the condenser and the capillary (or expansion valve).
Liquid storage tank: During the operation of the refrigeration system, the circulating amount of refrigerant in the system will change due to the change of working conditions or the adjustment of refrigeration capacity. Setting the liquid storage tank can balance and stabilize the refrigerant circulation in the system by using the liquid storage capacity of the liquid storage tank, so that the refrigeration system can be in normal operation. In addition, when a component in the refrigeration system fails and needs to be dismantled and repaired, the system refrigerant can be recovered to the liquid storage tank through certain operation methods.
The liquid storage tank is generally arranged between the condenser and the throttling element, so that the refrigerant liquid in the condenser can smoothly enter the liquid storage tank. The position of the liquid storage tank should be lower than that of the condenser.
Electromagnetic four-way reversing valve: after the electromagnetic coil is energized, it changes the action direction of the valve block in the valve body and changes the flow direction of the refrigerant. So as to achieve the purpose of cooling or heating.
three
Solenoid valve: Solenoid valve is usually installed in front of the expansion valve to directly control the amount of refrigerant entering the evaporator. It can also be installed before the compressor unloading cylinder to control the unloading of the compressor cylinder.
There are two kinds:
Direct opening and closing solenoid valve;
Indirect solenoid valve.
One-way valve: The one-way valve is usually connected in parallel with the auxiliary capillary, and the two are connected in series with the main capillary. One-way valve is a tubular element with a movable spherical or hemispherical plug made of stainless steel or nylon. Combined with capillary tube, it can adapt to two different operating conditions of refrigeration and heating.
5. Types and States of Refrigerant
Air conditioning refrigerants mainly include R22, R410A and R32.
R22 is a medium-temperature refrigerant, with the standard of -40.8 degrees, the solubility of water in R22 is very small, and it is mutually soluble with mineral oil, and R22 does not burn or explode, with little toxicity and strong permeability.
R410A is a HFC refrigerant which is composed of R32 and R125 by 50% and 50% by mass. [This article comes from WeChat official account, a refrigeration encyclopedia” target=_blank>, which belongs to a near azeotrope, and its thermodynamic properties are very close to that of a single refrigerant. Compared with R22, R410A’s condensation pressure is increased by 1.6 times, and it is a high-pressure refrigerant, so it is necessary to improve the compression strength of the system.
R32 is the abbreviation of difluoromethane, which is a kind of coolant with zero ozone loss potential. It is a gas at room temperature and a colorless and transparent liquid under its own pressure. It is soluble in oil and insoluble in water, and it is an energy-saving and carbon-reducing environment-friendly non-toxic refrigerant, but it is flammable and explosive!
6. Refrigerant status
Saturated refrigerant: Vapor-liquid conversion in saturated refrigerant is in transport equilibrium, and liquid and gas at this time are in saturation.
There is a one-to-one correspondence between saturation temperature and saturation pressure, and the saturation pressure increases with the increase of saturation temperature, and one of them will change and the other will change accordingly. In the system, the refrigerant in the evaporator absorbs heat and the refrigerant in the condenser releases heat, where the refrigerant is saturated.
Superheat: Under a certain pressure, the temperature of superheated steam exceeds the saturation temperature.
Overheating: the temperature of refrigerant vapor in superheated refrigerant is higher than the saturation temperature under the corresponding saturation pressure, and the liquid refrigerant will overheat after evaporation. In the case of overheating, there is no one-to-one correspondence between the temperature and pressure of refrigerant gas.
Near the outlet of the evaporator, the refrigerant continues to absorb heat after complete evaporation and becomes superheated refrigerant with a temperature higher than the saturation temperature. The refrigerant enters the compressor through the suction pipe in case of overheating.
Supercooling: The liquid temperature of the supercooled refrigerant is lower than the saturation temperature at the corresponding saturation pressure, and supercooling will only occur when there is no steam in the fluid refrigerant. In the case of supercooling, there is no one-to-one correspondence between the temperature and pressure of refrigerant liquid.
Between the outlet of the condenser and the throttle valve, the refrigerant may continue to cool exothermically and become supercooled after condensing into saturated liquid.
Whether in cold winter or hot summer, air conditioning is an essential household appliance in our home, especially now that people’s living standards have improved, air conditioning has entered thousands of households. Many owners think that choosing air conditioning is the most important thing. I don’t know if it is familiar, but the placement of air conditioning is even more difficult. If it is not in the right position, it will bring trouble to our lives. Many people don’t know the secret of air conditioning placement. Come and have a look with Xiaobian.for a long time commercial hvac systems It has an extraordinary development speed, and I believe that the future will be as overwhelming as ever. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/
Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!
Where are the air conditioners placed?
(1) How to place the air conditioner in the living room?
1. Air-conditioning is a kind of fast-running electrical appliance, so it will transfer the air flow from the outside to the home, such as the main disease in the southwest. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year. Correction method: use a small fan to change the wind direction opposite the air conditioner. In addition, if you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.
2. The most taboo of the air conditioner outlet is to blow to the financial position, and take away the wealth at home together with the cold wind, and the door at home is the main wealth. Therefore, if the air conditioner directly faces the door, it will not only drain the wealth, but also symbolize the popularity. It means that the home is not warm. Correction method: hang a glass screen or cloth curtain at the entrance to solve it.
3. The air outlet of the air conditioner directly blows the main chair in the living room (that is, the sofa where three people sit), so that the face sitting here is blown very uncomfortable, which means that the backer is unstable and affects the work and career fortune. Correction: Let the air outlet of the air conditioner come from the side, or move the position of the main sofa.
Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!
(2) How to place the air conditioner in the bedroom?
1. Air-conditioning often emits a certain amount of heat during refrigeration, so it must be installed far away from other electrical appliances and avoid being installed in corners, which can make the air-conditioning dissipate heat as soon as possible, ensure that it is not damaged, and prolong its service life.
2. The air conditioner is installed at a certain distance from the bed. If it is facing the bed or too close to the bed, it will easily lead to the user catching a cold or catching a cold, which will adversely affect people’s health. Therefore, everyone needs to pay special attention to this when installing the air conditioner.
Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!
3. Air conditioning is installed in the bedroom in the northeast direction, because the radiation in this direction will be relatively small, so that the harm to the human body can be reduced to. In real life, many owners will ignore this problem, which is actually a very serious misunderstanding.
4. The height of the air conditioner installed in the bedroom is very elegant. It is not appropriate to be too high or too low. It is recommended that it be higher than one meter and lower than two meters. This height is the most suitable, and its use effect will be in a new state, and it is more convenient for daily use.
Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!
What are the precautions for air conditioning placement?
1, kitchen air conditioning moving stove fire
It is the place where the whole family can fill their stomachs without installing a kitchen stove. If the air conditioner directly touches the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the occupants. In addition, the stove fire is also representative, so it has a great influence on the couple’s sexual life. Try not to install air conditioning in the kitchen, but if you must, try to blow the wind towards the ceiling or sideways.
2, the dining room air conditioning dirty food
Blowing the dining table directly is a big no-no, it will inevitably accumulate dust if the air conditioner blows the dining table directly, so it is very likely that the dust will fall into the hot food with the wind, and of course it is easier to cool the delicious meals on the table. Theoretically speaking, eating “dirty rice and cold dishes” for a long time will lead to the hidden worry of being defeated, so the air conditioner in the dining room should not be above or near the dining table.
Where is the most correct place for air conditioning? Many people don’t know the secret of air conditioning ~!
3, bedroom air conditioning to prevent discomfort
