When it comes to air conditioning, we have to popularize the working principle of air conditioning. Air conditioning is mainly about the "handling" of heat. When cooling, the indoor heat is transported to the outside. The external machine is hot air. When heating, the outdoor heat is transported to the inside. The external machine is cold air. Generally, the electric energy of the air conditioner is converted into heat energy by 1:3. In other words, one electric energy can be converted into three heat energy. This is the highest energy conversion in heater products. But these are all built under the condition of more than 5 degrees. When the temperature is below zero, its heating capacity will become weaker. Usually, electric auxiliary heating is used, and most of the electric energy is used for external defrosting, which will reduce the heating efficiency.

Secondly, the comfort of air conditioning is not as good as that of heating, let alone the collective heating in the north, which cannot be compared with it. It is easy for the upper part of the body to get hot and the lower part of the body to get cold when the air conditioning and heating deliver hot air. In addition, if you blow the hot air for a long time, the indoor air will become very dry and uncomfortable.

If you are choosing heating equipment, you can learn about the air-source heat pump. Its principle is the same as that of air conditioning, but because of the use of new environment-friendly refrigerant and jet enthalpy increasing process, it can operate normally in a low temperature environment of - 25 ℃, and the energy efficiency ratio is above 2.5. Under the same conditions, the heating cost of air source heat pump is lower than that of coal, gas and electric heating. It has the advantages of energy conservation, environmental protection, heat stability, and can meet the heating needs of most regions in China (especially in the northern region). It is the preferred solution for clean energy heating of civil commercial buildings.
