Is it good to use central air conditioning for cooling and heating in the community?

Now using ordinary central air conditioning for heating and cooling, it is better to choose air energy central air conditioning. Air energy central air conditioning can heat and cool by absorbing the heat in the air, which is very energy-saving. The heating function is its strength, and it can still heat efficiently in the north-10 degrees. The principle of refrigeration is the same as that of heating.

However, the process is the opposite. Whether cooling or heating, air energy heat pump central air conditioning does not need electric auxiliary, while ordinary central air conditioning has poor heating capacity and often needs electric auxiliary. Therefore, ordinary central air conditioning is not as energy-saving as air energy central air conditioning.

Moreover, in terms of comfort, because the air energy central air conditioner is a "water system", heating and cooling are neither dry nor wet, which is closer to the natural wind. Ordinary central air conditioning is a fluorine system. If you stay indoors for a long time, you will feel very dry and easily get air conditioning disease.
