How to heat the air conditioner in winter

When most air conditioners heat in winter, the external ambient temperature will have a great influence on air conditioning heating. Under normal circumstances, the lower the outside temperature, the lower the effect of regulating heat. When the outside temperature is below zero, it will not be heated again, which is also an important reason why most families in the northern region do not need air conditioning to heat the indoor temperature.

1, and the optimum heating temperature: 18-20℃

From the point of view of human comfort, people will feel comfortable if the indoor temperature is controlled between 18-20℃ in the indoor environment in winter. Because people wear a lot of clothes in winter, if the indoor temperature is higher than 20℃, they will feel a little hot. If the air conditioning temperature is set above 26℃ in winter and the heating temperature is too high in winter, the indoor air will be extremely dry, hurting people's body fluids and body fluids, making people feel turbid and hot, and the eyes, ears, nose, mouth, throat and skin will feel dry.

2. Optimum ambient temperature for heating: 7℃

It is so cold in winter that it is even below 0℃ in some places. The outdoor unit of air conditioner is easy to frost or freeze, so it must be defrosted constantly, so the load of air conditioner will increase and heating will be slower. The investigation shows that the heating effect is the best when the outdoor temperature is 7℃. As the temperature drops, the heating effect will also drop, and when it is as low as -5℃, the air conditioner basically has no heating effect. But if the inverter air conditioner is used, the temperature will work above-15℃.

The operation method of air conditioning heating is generally that many friends have used air conditioning in summer and found that they don't know how to heat the air conditioning when they use it in winter. It's actually quite simple. Press the mode key to adjust the heating function, the temperature is set to 30 degrees, and hot air will be emitted after 5- 10 minutes! Air conditioning in winter will cause many problems different from those in summer. For these problems, all friends who use air conditioners need to have a full understanding of their own air conditioners and their working principles in detail, so that they can solve them when they encounter problems.

Principle of air conditioning and heating Freon will be used in air conditioning and heating. Freon has the characteristics of condensation, liquefaction, exothermic evaporation and gasification and heat absorption. When the air conditioner is heating, the compressor will pressurize the gas Freon, making it a high-temperature and high-pressure gas, and then condense and liquefy it through the heat exchanger of the indoor unit, releasing a lot of heat and raising the indoor air temperature. Then, the throttling device will decompress the liquid Freon, evaporate and absorb the heat of outdoor air through the heat exchanger of the outdoor unit, and turn it into gas to start the next cycle.
