Air coolers cannot replace central air conditioning. Due to the limitations of the use of air coolers, they cannot replace central air conditioning. From the historical development process of central air conditioning, it seems that air coolers were the first to emerge, and finally central air conditioning emerged. Over the years, air coolers have not developed rapidly precisely because they have been relatively limited in their application throughout the entire process. Currently, there are limitations in the use of products such as air coolers, including Ningbo air coolers and Ningbo air coolers

1. By utilizing water evaporation to absorb heat and carry out refrigeration, the indoor air humidity can be increased when the temperature in the room is lowered to a certain extent; Areas with special requirements for indoor air humidity, especially those with abundant electrical products, should not be used;

2. The cooling force of the air cooler is very limited. When the volume size of the air cooler is matched with the room size specification, it can generate a temperature reduction of 3-8 * C in the room. The higher the natural ambient temperature, the smaller the cooling force that can be applied;

3. The air cooler can be used when it gets cold in summer, but it may not be used for heating in winter or for heating with a pure electric heater;

4. Not suitable for high humidity climate in coastal and southern regions. And in addition to regulating temperature and humidity, central air conditioning also has the functions of air filtration and ash removal, which can meet human application requirements much larger than air coolers.
