What is the difference between the air conditioner and the air conditioner 27 degrees?

The air conditioner turns on the air conditioner 27 degrees and the heating 27 works differently:

The difference in how it works:

1. The working principle of 27 degree refrigeration of air conditioner:

The compressor compresses the gaseous freon into a gaseous freon at high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes liquid freon at room temperature and high pressure, so the outdoor unit blows hot air.

The liquid freon enters the evaporator (indoor unit) through the capillary, the space suddenly increases, the pressure decreases, the liquid freon will vaporize and become gaseous low-temperature freon, thereby absorbing a large amount of heat, the evaporator will become cold, and the fan of the indoor unit will blow the indoor air through the evaporator, so the indoor unit blows out of the cold air.

2. The working principle of 25 degree heating of air conditioner:

Heat pump heating is the use of a compressed condenser in a refrigeration system to heat indoor air. When the air conditioner is working in refrigeration, the low-pressure refrigerant liquid is in the evaporator, and the high-temperature and high-pressure refrigerant is heated and condensed in the condenser.

Heat pump heating is to reverse the position of the suction and exhaust pipes of the refrigeration system through electromagnetic commutation. The indoor coil of the original refrigeration evaporator becomes a condenser during heating, so that the refrigeration system absorbs heat from the outside and releases heat from the interior to achieve the purpose of heating.

One blows cold air, the other blows hot air.

The outside temperature is different, one is refrigeration, and the other is harnessing.

It can be turned on 27 degrees, and at the same time, the fan motor of the indoor unit can be adjusted to the middle wind gear or low windshield.

It is recommended to clean the indoor unit with return air.

The temperature of the air conditioner must be set within a reasonable temperature range, that is, it should be 26 28 in summer and 18 20 in winter. The temperature of the air conditioner should not be too different between indoor and outdoor, generally 5 10 is appropriate. If the temperature difference is too large, it is easy to get a cold or other illness due to sudden changes in temperature when entering and exiting.

Generally speaking, when we use air conditioning to heat in winter, we can adjust the temperature to about 18 to 23 degrees, after all, the heating in the north is about the same temperature, we let the home keep this temperature, neither feel cold, but also will not feel a huge temperature difference when going out to cause a cold, this temperature is the most suitable for the human body to live in winter, and the air conditioner runs under this temperature condition, which saves a lot of electricity bills than high temperatures.

Generally, we need to clean the filter before using the air conditioner in winter, after all, there will be a lot of dust and pollutants left on the filter screen of the air conditioner after using it in summer, if you turn on the air conditioner directly, then these dirty things will be absorbed by the human body, which is easy to affect your health, so you must remember to clean the air conditioner in time to ensure safe use.

Setting the temperature is a tricky task. The temperature of the air conditioner in the room is based on the standard of feeling comfortable for yourself, and the others are just a reference, 26 degrees in summer and 18 degrees in winter. In the summer, if you are too fat, it will be very uncomfortable to set 26 degrees, and if you are on the thin side, you will feel very cold in the winter.

In fact, no matter how many degrees the air conditioner is turned on at home, everyone can feel comfortable.

The air conditioner is suitable for 27 degrees. According to relevant scientific studies, when the ambient temperature is around 25 degrees,Relative humidityAt 40%-70%, the temperature felt by the human body is the most comfortable, and there is no need to open the air mill to know the adjustment to cool down. When the temperature is greater than 26 degrees, reaching 27 degrees, humanFeel the temperatureIt will feel very hot, and when the humidity is greater than 70%, it will feel stuffy, and you can turn on the air conditioner to adjust the indoor temperature.

In addition, if the air conditioner is turned on for too long, the air in the room will become dirty and dull, so it is generally necessary to change the air every few hours, which is conducive to keeping the indoor air fresh. At night, in order to avoid the temperature of the air conditioner being too cold in the second half of the night, you can also use the timer function to ensure a stable sleep without being too cold.

Tips for using air conditioners

1. Clean and check whether the outdoor unit is firmly installed and the grounding wire is cleaned regularly.

If there is no disconnection, falling off or rust, be sure to ensure the safety of the outdoor unit of the air conditioner. Secondly, when the air conditioner is started, check whether the air conditioning at the air outlet is sufficient and whether the cooling effect is normal.

2. If the cooling is not enough, it means that the air conditioner may leak fluorine or do not know which component is abnormal, at this time, you should contact the after-sales or maintenance personnel at the first time. Also clean the filter and check that the air conditioner's heat exchanger vents are clear. For air conditioners with a service life of more than two years, you can ask professional air conditioners to come to clean and maintain them.

Summary. Hello, you can turn on the 27 degree refrigeration, but it is not recommended to turn the air conditioner on to this temperature for a long time. This is because:

2.Not good for health: Turning on the air conditioner to too low a temperature will make the indoor air too dry, resulting in dehydration and dry throat, which is not good for health.

3.Affect the life of the air conditioner: Turning the air conditioner to too low a temperature for a long time will increase the load of the air conditioner, accelerate the wear and tear of the air conditioner, and shorten the life of the air conditioner.

All things considered, it is generally recommended to set the temperature of the air conditioner below 26 degrees, and it is most appropriate to keep the indoor temperature between 24-26 degrees. If you need a better cooling environment, you can improve the comfort of the indoor temperature in other ways, such as using ventilation systems, using sunshade curtains, etc.

Is 27 degrees too low a temperature?

Normally, 27 degrees is a low temperature for an air conditioner, because it means that more energy needs to be used to maintain this temperature, and the energy consumption of the air conditioner will increase, making the body feel uncomfortable. According to the relevant regulations in China, the temperature of the air conditioner in summer should be between 26-28 degrees Celsius, so the temperature setting of 27 degrees is still low. Of course, it is also necessary to combine personal feelings and environmental factors to determine whether it is too low.

1. Different working modes have different effects.

2. When the air conditioner is running in refrigeration mode, the indoor unit is an evaporator.

It is used to cool down, and the indoor unit is a condenser when heating mode.

It is used to heat up. For example, if the air conditioning refrigeration setting temperature is 27 degrees, the air temperature of the air outlet of the air conditioner indoor unit is normally below 16 degrees, that is, the air temperature of 27 degrees will be reduced by more than 10 degrees after the air enters the air conditioner indoor unit;

3. When the heating of the air conditioner is set to 27 degrees, the air inlet is 27 degrees, and the outlet air temperature is mostly above 45 degrees, and the temperature of the air rises by more than 15 degrees after the indoor unit is circulated, and the hot air comes out.

4. Air conditioning and refrigeration 27: The actual air outlet temperature of the indoor unit will be much higher than 25, air conditioning system.

Indoor temperatures rise as heat is continuously transferred from the ambient outdoor air into the room.

5. Air conditioning heating 27 is used when the weather is colder, while air conditioning and refrigeration 25 is used when the weather is hotter, and the two seasons are different.

It was nice to have the air conditioning on 27 degrees.

From the aspect of our human health, it will be better when we set the air conditioner to about 27 degrees, because in summer, the temperature is very high, if we use the air conditioner indoors, because people who work in the office are often sitting, it is better to set the temperature of the air conditioner at about 27 degrees.

Because in the summer, the outdoor temperature is about 35 degrees, if the indoor temperature is set at 27 degrees, the temperature difference between indoor and outdoor does not exceed 10 degrees, because if the temperature difference exceeds 10 degrees, if we stay in this environment for a long time, we will feel uncomfortable and are prone to air conditioning disease. And if the temperature difference is not too high, even if we go out of the air-conditioned room to rent Hongzhen, we will not feel particularly hot, which can solve a lot of trouble for us.

In terms of our sleep, 27 is also more appropriate. I also turn on 27 degrees to sleep at night because I have a baby at home. If the air conditioner is turned down too low, such as below 27 degrees, it will be colder for the baby, and you still need to cover the quilt.

If it's at 27 or 28 degrees, you can cover your stomach a little.

The temperature set by the air conditioner is the ambient temperature, that is to say, when the air conditioner temperature is set at 27 degrees, and the air conditioner runs for a period of time, the ambient temperature reaches 27 degrees, and the air conditioner compressor will shut down or run slowly with inverter. So the ambient temperature of 30 degrees is definitely higher than the ambient temperature of 27 degrees. When cooling, they blow out a certain temperature of cold.

It's the same.

Of course, the lower the temperature adjustment, the colder it is, provided that the room temperature can be lowered.

27 degrees is definitely lower than 30 degrees, so 27 degrees is colder.

The air conditioner is definitely cooler at 27 degrees than 30 degrees when cooling.

Air conditioning has cooling options and heating options.

1. The difference between air-conditioned air-conditioning and air-conditioning:

1. The temperature of the two is different.

The air conditioner is cooler and the heat is warmer.

2. The two have different functions.

Air conditioners are often used for indoor cooling in summer, and heating is often used for indoor heating in winter.

3. The principle of action is different.

1) When the air conditioner is heating, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (condenser at this time), and the condensation is liquefied and exothermic to become a liquid, and the air in the room is heated at the same time, so as to achieve the purpose of increasing the indoor temperature.

The liquid freon is depressurized by the throttling device, enters the heat exchanger of the outdoor unit (in this case, the evaporator), evaporates and vaporizes to absorb heat and become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder).

Freon, which becomes a gas, enters the compressor again to start the next cycle.

2) When the air conditioner is refrigerated, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the outdoor unit (condenser at this time), and the condensation is liquefied and exothermic to become a liquid, and the heat is released to the atmosphere at the same time.

The liquid freon is depressurized by the throttling device, enters the heat exchanger of the indoor unit (evaporator at this time), evaporates and vaporizes to absorb heat, becomes a gas, and absorbs the heat of the indoor air at the same time, so as to achieve the purpose of reducing the indoor temperature.

Freon, which becomes a gas, enters the compressor again to start the next cycle.

Second, the heating of 28 degrees is warm, and the reason why the air conditioner of 28 degrees is really cold:

Because this 28 degrees is a set temperature, it is a parameter to regulate the operation of the air conditioner.

It means that after the air conditioner is running, the room temperature sensor will temporarily operate when the temperature is equal to the set 28 degrees, which is an energy-saving control measure of the air conditioner, and has nothing to do with the operating principle of cooling and heating.

Of course, air conditioning and refrigeration are cold air coming out, and when heating, of course, warm air comes out.

The difference between air conditioning and air conditioning heating is how they work. Air conditioners are circulating refrigerants to transfer heat from the interior to the outdoors, thereby reducing the indoor temperature. Air conditioners, on the other hand, use the heat generator cycle to transfer heat from the outside to the interior, thereby increasing the indoor temperature.

Therefore, air conditioning cooling and air conditioning heating work on opposite principles.

As to why a 28 degree heating is warm, and a 28 degree heating is indeed cold, this involves a concept – the temperature difference. Temperature difference refers to the difference in temperature between two parts of an object. When the temperature difference is larger, the temperature difference felt by the human body is also greater.

For example, when the outdoor burial temperature is 5 degrees Celsius and the indoor temperature is 28 degrees, the temperature difference between indoor and outdoor is 23 degrees, and the temperature difference felt by the human body will be more obvious.

Therefore, when the air conditioner is set to 28 degrees Celsius, the temperature difference between the indoor temperature and the outdoor temperature is only about 23 degrees, so people feel warm. When the air conditioner is set to 28 degrees Celsius, the temperature difference between the indoor temperature and the outdoor temperature is about 23 degrees, but because the human body is more sensitive to low temperatures, people will feel very cold.

In conclusion, air conditioning and air conditioning work differently, and the human body's perception of temperature is also related to the temperature difference. Therefore, even if the temperature is set to the same, the temperature that people feel may be different.

The air conditioner can be set with air conditioning and heating, and setting 28 degrees does not represent the actual temperature, but is a parameter of the air conditioner.
