When we use air conditioning everyday, we may notice that our air conditioning has a lot of modes. The most common mode we use is probably refrigeration and dehumidification. When it comes to dehumidification, people often feel that this mode is no different from refrigeration. Is this really the case? Xiaobian next to introduce the difference between refrigeration and dehumidification, as well as the differences and similarities between refrigeration and dehumidification work. So you can use both patterns correctly.
How refrigeration and dehumidification work
Refrigeration: refrigeration principle is that the Carnot cycle air conditioner hanging in the outdoor is the host, mainly compressor, heat dissipation pipe, fan, compressor refrigerant from gaseous compression into liquid heat, heat dissipation pipe, fan, cooling refrigerant into the room through the copper pipe, copper pipe diameter, pressure reduction, liquid refrigerant from liquid into gas, heat to the surrounding environment, cold air. The cool air blown out is the result of indoor air contacting the condenser (copper pipe) and heat being sucked away. The dehumidification function is relative to the refrigeration function, the fan has been running at a low speed, the compressor is on and off, the refrigeration system for intermittent refrigeration cycle, the cooling capacity is mostly used to balance the latent heat of indoor air, that is, water vapor into condensate water. Therefore, the dehumidification function of air conditioning saves more power than the refrigeration function.
Dehumidification: in the process of refrigeration, the temperature of the humid air through the air conditioner evaporator will be greatly reduced, the air humidity is in a susaturated state, excess water vapor in the form of condensation, condensation on the fin of the evaporator, that is, “condensation”, until the refrigeration mode reaches a certain equilibrium state, air humidity will fall to a certain level.
1. The similarities of air conditioning refrigeration and dehumidification:
Air conditioning operation refrigeration mode, while reducing the air temperature must be removed at the same time water vapor; Air conditioning operation dehumidification mode, in the removal of water vapor at the same time must reduce the air temperature; So whether cooling or dehumidification, lowering air temperature and removing water vapor are inseparable. Whether refrigeration or dehumidification, when indoor hot air passes through the heat exchanger of the indoor unit of the air conditioner, the water steam in the hot air is condensed into condensate water at low temperature, and the condensate water is discharged to the outdoor through the drainage pipe; At the same time, the cold air after heat transfer blows out from the air outlet of the air conditioner.
Two, air conditioning refrigeration and dehumidification
Refrigeration: For the purpose of reducing air temperature while removing water vapor. Select the cooling mode. The cooling temperature and wind speed can be turned up or down. The air conditioner operates in refrigeration mode according to the artificially selected temperature and wind speed to achieve the purpose of reducing the air temperature (at the same time discharging condensed water), and the cold wind blown out is relatively strong.
Dehumidification: For the purpose of removing water vapor, reduce the air temperature and select a dehumidification mode. The dehumidification temperature and wind speed can not be adjusted up or down. The air conditioner operates in dehumidification mode in accordance with the low temperature and wind speed set automatically to remove water vapor from the air (while blowing out cold air). The cold air blown out is weak and soft. For the purpose of removing water vapor and lowering air temperature.
Summary: In the above article, Xiaobian introduces the working principle of refrigeration and dehumidification function of air conditioning. While the two models may feel very similar, they work very differently. At the same time, Xiaobian also introduced the similarities and differences of air conditioning refrigeration and dehumidification. The biggest thing they have in common is their ability to remove moisture from the air. But the difference is huge. The purpose of refrigeration is to reduce temperature, and the purpose of dehumidification is to remove water vapor.
