How long does it take to dehumidify the air conditioner?
How long does it take to dehumidify the air conditioner? In fact, this question is very difficult to answer. Generally, it depends on whether the air conditioner dehumidifies in cooling or non-cooling mode, as well as the temperature range set by the air conditioner, as well as the environmental range and humidity of the air conditioner, ranging from half an hour to several hours. It depends, so it's difficult to explain how long it takes for the air conditioner to dehumidify. In the following two situations, the related situation of air conditioning dehumidification is introduced:
1, air conditioning dehumidification under refrigeration.
Air conditioning refrigeration dehumidification, in the process of refrigeration, the temperature of humid air will drop greatly after passing through the evaporator of air conditioning, 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. 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 a "side effect" accompanying the refrigeration process, reducing humidity.
2. Dehumidification in non-cooling mode of air conditioner
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. That is, 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 rainy season in the south and the hot and humid weather in the north can turn on the "dehumidification mode" of air conditioning. At this time, the moisture in the air will soon be discharged outside, and we will not 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.
The above is the introduction of how long it takes for air conditioning dehumidification and under what circumstances. I believe that everyone has a certain understanding of the dehumidification function of air conditioners. Generally speaking, air conditioning has a certain dehumidification function, but dehumidification is very slow and the scope is very small. Dehumidification is only an additional function of air conditioning, and the dehumidification function is very general. Can be used for small area dehumidification. If it is humid and needs large area dehumidification, it is recommended that you use a professional dehumidifier. It depends.
