It is time to wear clothes randomly in autumn and winter. The day before, I was still T-shirts and shorts, and a few days later I started to want to go out with a blanket. The 26-degree air conditioner has also changed from cooling to heating, and a question has also come to many people's minds: Why does the body feel very different in the 26-degree in the two modes?

This doubt reflects a very common cognitive misunderstanding: you may think that the set temperature pressed by the remote control is the air supply temperature of the air conditioner, but in fact they are not the same.

In autumn, it is not only difficult to wear the right clothes, but also difficult to adjust the temperature of the air conditioner / Tuchuang Creative

For example, in summer, the temperature of the room should be reduced from a high temperature of 35 or 36 degrees to a comfortable 26 degrees within a few minutes. It is difficult to achieve the air outlet temperature of 26 degrees in a short time. Therefore, the air outlet temperature of the air conditioner will be much lower than 26 degrees, or even below 18 degrees [1][2].

The same is true. When the indoor temperature is low, the air outlet temperature of the air conditioner will be very high during heating, usually around 40 degrees. Only in this way can the heating be maintained after mixing the lower-temperature air in the room [3][4]. means that the set temperature is only the temperature you expect, not the air supply temperature. So the question is, what will happen if you turn on the cooling 26 degrees and the heating 26 degrees in two rooms with the same room temperature as 30 degrees?

In order to answer this question, let’s first figure out how the air conditioner works.

When the air conditioner is refrigerated, the low-pressure gaseous refrigerant is sucked into the compressor and becomes a high-temperature and high-pressure gas; then, the refrigerant flows into the condenser outdoor, condenses into a high-pressure liquid, and releases a large amount of heat outside; then, the throttling device reduces the pressure and cools down, and the high-pressure liquid becomes a low-temperature and low-pressure gas-liquid mixture.

Finally, the gas-liquid mixture enters the evaporator of the indoor unit, absorbing a large amount of heat during the continuous vaporization process, the air temperature drops sharply, blows into the room, and cools down.

Air conditioner will exchange heat with the outside air when refrigerating or heating. Therefore, the air conditioner outdoor unit blows hot air in summer and cold air in winter / Wang Xiaolu, Zheng Huifan, Yang Lei, Li Yuna Wu En. (2016). HVAC technology. China Building Materials Industry Press .

The heating mechanism is just the opposite. The refrigerant changes from gaseous to liquid, releasing a lot of heat, and the indoor heat also heats up.

In order to improve the heating effect, manufacturers may also add electric heating wires [5][6] to the air conditioner.

In order to cool and heat normally, there is a temperature sensing element inside the air conditioner. According to the information feedback from the sensing element, the air conditioner will handle the compressor operation or air outlet temperature accordingly. For example, the fixed frequency air conditioner will run the compressor with all its strength when it is turned on, and output a constant temperature cold air. When the indoor temperature is lower than the set temperature, it will stop cooling. When the indoor temperature slowly rises, it will run cooling again, and repeat. After the

variable frequency air conditioner is turned on, the temperature will also be quickly reduced. However, the difference is that it will not stop operating at this time, but instead reduces the operating frequency of the compressor and adjusts the air outlet temperature and air volume according to the room temperature, so that the indoor temperature can be kept smoothly within the fluctuation range of the set temperature [7][8][9].

So back to this question, what will happen to the air conditioner with the same temperature in different modes when facing a room of 30 degrees?

When the indoor temperature is 30 degrees and the cooling is required for 26 degrees, the air conditioner will perform refrigeration operations according to the instructions. However, when heating is required at 26 degrees, old air conditioners with low temperature sensitivity will start heating for a period of time first. When the room temperature is higher than the set temperature, it will stop working or blow natural wind.

Fixed frequency and variable frequency air conditioners are also "intelligent" / Tuchuang Creative

However, if it is an air conditioner with a newer model, it detects that the room temperature is already higher than the set temperature when it receives the command, either it will not start or it will blow natural wind [9][10].

So, as a ruthless machine with only binary working mode, the air conditioner will only moderate the temperature according to your instructions and indoor and outdoor temperature difference. It only has 26 degrees of cooling and 26 degrees of heating, and there is no simple 26 degrees (manual dog head).Written by
