is the air conditioning dehumidification mode more power efficient in summer? In hot summer, air conditioning is an essential household appliance in our daily life. In summer, we usually choose refrigeration mode, but have you ever used the dehumidification mode on air conditioning? Xiaobian once read an article, saying that dehumidification mode is more energy-saving than refrigeration mode, is it true?
The difference between air conditioning dehumidification and refrigeration
Refrigeration: the refrigerant vaporizes in the indoor evaporator of the air conditioner to take away heat and cool the indoor air flowing through the radiator of the evaporator The vaporized refrigerant is compressed and liquefied outside by the compressor to release heat, and the heat is transferred to the outdoor air through the radiator. Such a continuous cycle to achieve the role of indoor air cooling.
Dehumidification: in the process of refrigeration, the temperature of moist air will drop significantly after passing through the evaporator of the air conditioner. The air humidity is in an oversaturated state, and the excess water vapor will be separated out in the form of condensation water and condensed on the fins of the evaporator, i.e. "condensation". When the refrigeration mode reaches a certain balance state, the air humidity will also drop to a certain level. (this article is exclusively compiled by WYH, editor of sihai.com.

Differences between air conditioning refrigeration and dehumidification
Refrigeration: to reduce the air temperature and remove the water vapor at the same time. Select the refrigeration mode, the refrigeration temperature and wind speed can be adjusted up or down. The air conditioner operates in refrigeration mode according to the temperature and wind speed selected manually, so as to reduce the air temperature (discharge the condensate water at the same time), and the cold air blown out is relatively strong.
Dehumidification: for the purpose of removing water vapor and reducing air temperature, choose dehumidification mode. The temperature and wind speed of dehumidification cannot be adjusted up or down. The air conditioner operates in dehumidification mode according to the low temperature and low wind speed set automatically, so as to achieve the purpose of removing water vapor in the air (and blowing out cold air at the same time), and the cold air blown out is relatively weak and soft. In order to remove water vapor and reduce air temperature. (this article is exclusively compiled by WYH, editor of sihai.com. If you need to reprint it, please indicate the source and source.

Which is more economical for air conditioning refrigeration or dehumidification
Air conditioning dehumidification and refrigeration, which are more cost-effective, are relatively speaking. When the air conditioning is in the low set temperature refrigeration state, it is also dehumidification in fact, and the operation time is long, which also costs electricity; when the air conditioning is in the high set temperature refrigeration state, the operation time is short, which is relatively low refrigeration state, which saves electricity In addition, when the air conditioner is in dehumidification operation state, the design (default humidity) of the computer board chip of the air conditioner is 60% - 65% (suitable humidity for human body). When the humidity is lower than this, the air conditioner will stop running and no longer consume power However, when the refrigeration state is set to operate at a low temperature, the air conditioner needs a long time to complete the set temperature operation, so the power consumption is large; otherwise, when the refrigeration state is set to a high temperature, the air conditioner will achieve a high set effect in a short time after operation, the compressor of the air conditioner will stop, and the power consumption will be small (which is less than the power consumption in the dehumidification state). After that, the level of environmental humidity will also affect the power consumption of the dehumidification function of the air conditioner So it's just a relative concept, it can't be too absolute!
