Air conditioning dehumidification signs and principles

The air conditioning dehumidification sign is the description on the air conditioning remote control. There are two modes of air conditioning dehumidification, namely refrigeration mode and independent dehumidification mode. Here, we will introduce these two modes in detail, as well as the method of heating the air outlet temperature and the working principle of the dehumidifier.

Refrigeration mode

The refrigeration process of air conditioner is bound to be accompanied by dehumidification. After the humid air passes through the evaporator of the air conditioner, the temperature will drop greatly and the air humidity will be in a supersaturated state. Excess water vapor will precipitate in the form of condensed water and condense on the fins of the evaporator, that is, "condensation". When the refrigeration mode reaches a certain equilibrium state, the air humidity will also drop to a certain level.

Independent dehumidification mode

This method is called constant temperature dehumidification by the insiders. Its basic principle is to reheat the air cooled by the evaporator to the original temperature, and then send it indoors to keep the indoor environment relatively constant when the humidity drops.

Method for heating air outlet temperature

There are two ways to heat the temperature of the air outlet: one is to use an electric heating component to heat the air passing through the evaporator; The other is to use the heat generated by the condenser to heat the dehumidified air. These two heating methods are only different from the heating device and heating method, and they are purely physical.

Working principle of dehumidifier

The working principle of the dehumidifier is simply to use the moisture in the air to condense into frost when it enters the evaporator of the dehumidifier, then accumulate and drip out, and then discharge into the sewer, so as to achieve the purpose of reducing the humidity of the space. Its principle is similar to the dehumidification principle of air conditioner in refrigeration mode.
