Many air conditioners also have dehumidification function. Can they replace dehumidifiers? Do they have the same dehumidification principle? Today, let the editor of Nysda, one of the top 10 dehumidifier brands, introduce you to the relevant content, and I hope it will be helpful to you.
1. The principle of air conditioning dehumidification
The air conditioner has two dehumidification functions
Cooling mode is the basic function of any air conditioner. The refrigeration process of the air conditioner must be accompanied by dehumidification. After the humid air passes through the air conditioner evaporator, the temperature will drop greatly. The air humidity is supersaturated. Excess steam will be separated in the form of condensed water and condense on the fins of the evaporator, that is, condensed water. When the cooling method reaches a certain equilibrium state, the air humidity will also drop to a certain level.
Vertical dehumidification is called constant temperature dehumidification in the industry. The basic principle is to reheat the cooling air passing through the evaporator to its original temperature, and then send it into the room when the humidity drops, so that the indoor environment remains relatively constant.
There are two ways to heat the outlet temperature: one is to use electric heating elements to heat the air passing through the evaporator. This type of air conditioner is equipped with an electric heating device on the indoor unit. When the air flows out of the condensed water through the evaporator (the surface temperature is low), the electric heating device heats the cooled air to make the temperature of the air outlet and the air inlet of the air conditioner basically the same; the second is to use the heat generated by the condenser to dehumidify the air Heat up. The air conditioner is equipped with two heat exchangers A and B, which are switched to the evaporator and condenser in the vertical dehumidification mode. Similarly, the air passes through the evaporator a (low surface temperature) to separate the condensed water, and then the condenser B (high surface temperature) replaces the role of the electric heating element in mode I, which also makes the temperature of the air outlet and the air inlet of the air conditioner basically the same. These two heating methods are only different from purely physical heating devices and heating methods.
2. Dehumidification principle of dehumidifier
The working principle of the dehumidifier is very simple. It uses the moisture in the air to condense and frost when it enters the evaporator of the dehumidifier, then accumulates and drips, and then discharges to the lower outlet, so as to achieve the purpose of reducing the humidity in the space. The principle is similar to the principle of dehumidification of refrigeration and air conditioning.
