Background

With the social progress and the improvement of the life quality of people, the air conditioner becomes essential in daily life of people. Common air conditioners in the market at present have the functions of temperature regulation and dehumidification, but the dehumidification mode is that a large amount of condensed water is generated by cooling air to a dew point, and the dehumidification mode can cause the surface of an air conditioner coil to be wet, dust is easy to accumulate, mold and bacteria are easy to grow, and serious secondary pollution is caused to air supply; in addition, the air cooled to the condensation point is too low in temperature, so that the comfort of a human body is affected, and if a treatment mode of reheating after dehumidification is adopted, the cold and heat are offset, so that a large amount of energy is wasted.
