Air coolers can't replace central air conditioning. Because of the limitations of the use of air coolers, it is decided that it can not replace the central air conditioning. From the historical development history of central air conditioning, it seems that the air cooler was the first and the central air conditioner finally occurred. Over the years, the air cooler has not been able to develop rapidly because it has been relatively limited in the whole process of application. At present, there are the following limitations in the use of air coolers:

1. Carry out refrigeration with the help of moisture evaporation heat absorption, which can increase the indoor air humidity when the temperature in the room is reduced to a certain extent; The area with special requirements for indoor air humidity, especially in the room is very rich in electrical goods should not be used;

2. The air cooler temperature reduction force is very limited, when the air cooler volume size and room size specifications are matched, the temperature reduction of 3~8*C can be generated for the room, the greater the natural environment temperature, the smaller the temperature reduction force;

3. Air cooler can be used after cold in summer, winter heating or pure electric heater heating or can not be used;

4. It is not suitable for high humidity weather in coastal areas and southern areas. And the central air conditioning can complete the adjustment of temperature and humidity, but also has the effect of air filtration and ash removal, it can meet the requirements of people's application is much larger than the air cooler.
