Air cooler can not replace central air conditioning. Because of the limitations of air cooler application, it is determined that it can not replace central air conditioning. From the historical time development history of air conditioning, it is the first air cooler, and then the central air conditioning. Over the years, the air cooler has been unable to develop rapidly precisely because it has been relatively limited in use. At present, there are the following limitations in the use of air cooler products:

1. With the help of water evaporation and heat absorption refrigeration, the temperature in the room is reduced to a certain extent, so that the indoor air humidity is increased; The area with special requirements for indoor air humidity, especially the area with abundant electronic equipment in the room is not suitable for application;

2. The air cooler temperature reduction is very limited, when the air cooler volume size and room area specifications are paired, can produce 3~8° C temperature reduction for the room, the greater the natural environment temperature, the smaller the temperature reduction;

3. The air cooler can be used after cooling in summer, but can not be used for heating or pure electric heater in winter; 4. It is not suitable for coastal areas and southern regions with high humidity.

In addition to the control of temperature and humidity, central air conditioning also has the function of air filtration and ash removal. It can meet the application standards of people and is much larger than the air cooler.
