How to dehumidify with air conditioner

Lead: There are two common dehumidification methods for air conditioners. The first is refrigeration and dehumidification; The other is an independent dehumidification function. Let's talk about how air conditioning dehumidification works.

How does air conditioning dehumidification work? 1. air conditioning refrigeration dehumidification. In the process of refrigeration, the temperature of humid air will drop greatly after passing through the evaporator of air conditioner, and the air humidity is in a state of supersaturation. 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 drop to a certain level. Therefore, when air conditioning is used for refrigeration, not only the air temperature decreases, but also the air humidity decreases. This is the working principle of dehumidification in air conditioning refrigeration mode, which is actually accompanied by refrigeration process? Side effects? , reduce humidity.

2. What is the working principle of independent dehumidification function of air conditioner in non-cooling mode? Now many air conditioners have independent dehumidification function. In fact, their working principle is to reheat the air cooled by the evaporator to the original temperature and then send it indoors. In other words, the indoor fan has been running at a low speed, the compressor is turned on and off, and the refrigeration system does intermittent refrigeration cycle. Most of the generated refrigeration capacity is used to balance the latent heat of indoor air, that is, water vapor becomes condensed water. A small part is used to balance sensible heat, that is, to lower some indoor temperatures. This continuous circulation keeps the room temperature near the set value, and at the same time removes a lot of water in the air. In this way, when the humidity drops, the indoor environment remains relatively constant. The refrigeration of air conditioner is only used for condensation, and there is little control over temperature, so this dehumidification is called constant temperature dehumidification.

How to use the dehumidification function of air conditioner? The dehumidifying mode is to make the whole air conditioner in a dehumidifying operation state. At this time, the fan of the indoor unit runs very slowly, which is to facilitate the condensation of water vapor in the air into liquid. Generally, when the air conditioner reaches the set temperature in dehumidification mode, the outdoor machine will stop running to avoid the dew on the condenser from evaporating again.

The rainy season in the south and the hot and humid weather in the north, we can turn on the air conditioner. In dehumidification mode, the moisture in the air will be discharged out of the room quickly, so we won't feel uncomfortable because of too much moisture. At the same time, the air conditioner will continue to blow cold air to keep the indoor temperature suitable, and the compressor and outdoor machine will stop running for a period of time at the right time, which saves a lot of electricity compared with the simple refrigeration mode.

When using the air conditioning dehumidification mode, it should be noted that if the outdoor temperature is high and the air is dry, do not turn on the dehumidification mode for a long time to avoid damaging the compressor. Generally, when the outdoor temperature is higher than 40 degrees, the normal refrigeration mode should be used. Only at night when the temperature is relatively low and the humidity is high can the dehumidification mode be started in time to achieve the effect of adjusting indoor temperature and humidity.

Understanding the working principle and usage of air conditioning dehumidification mode is beneficial for us to use and maintain air conditioning better and create a comfortable space for our home environment.
