Air conditioning is indispensable in the summer, do you usually set the air conditioner to dehumidify or cool?
Air conditioner dehumidification and refrigeration in the end which is more power-saving and once rushed to the hot search It seems that the big guys are just as confused ↓↓↓
Air conditioning dehumidification
vs
Air conditioning cooling
01What is the difference between dehumidification and refrigeration?
#除湿
When using the air conditioning dehumidification function, the air conditioner indoor hair dryer will maintain low speed operation, and the compressor will also operate intermittently, so that continuous circulation can ensure that the humidity in the room is constant.
Dehumidification is mainly to remove water vapor for the purpose, while reducing the air temperature, temperature and wind speed can not be adjusted up or down, the cold air blown out is relatively soft.
#制冷
When using air conditioning refrigeration mode, the air conditioning compressor and hair dryer will continue to operate to quickly reduce the temperature in the room.
The refrigeration mode is mainly for rapid cooling, while removing water vapor, the temperature and wind speed can be adjusted up or down, and the cold air blown out is relatively strong.
Simply put
Dehumidification mode = reduced air outlet + continuous dehumidification
Cooling mode = normal air outlet + continuous dehumidification
02Dehumidification vs refrigeration, which saves electricity?
Liu Chuanping, a professor at the Department of Thermal Science and Energy Engineering of the University of Science and Technology Beijing, introduced that in fact, dehumidification is a lower "refrigeration" than the refrigeration temperature, which reduces the temperature to the extent that the water vapor in the air can be condensed, reducing the humidity in the room, and as the humidity drops, the temperature of the human skin will also drop, and people will naturally feel cooler. The choice of the two modes can be determined according to the indoor temperature, when the temperature is 20 °C-30 °C, the dehumidification mode is less power-saving than the refrigeration mode; When the temperature > 30°C, the electricity consumption of dehumidification and refrigeration modes is similar. That is to say, if the indoor temperature is high, the refrigeration is turned on; The indoor temperature is not too high, but the humidity is large, then turn on dehumidification. Every time the air conditioner is turned up by 1 degree, the electricity load can be reduced by about 10%, so adjusting the temperature of the air conditioner by two degrees also saves power.
03How to use refrigeration and dehumidification mode rationally?
1
In the humid and hot weather, first open the refrigeration, and then change to dehumidification after the room temperature drops, which feels as cool as it is, which can save electricity and achieve the effect of dehumidification.
2
The simple dehumidification function is only suitable for the rainy season when the temperature is not too high, and it is necessary to cool down in the high temperature season in the middle of summer, or the refrigeration is more direct.
3
The sunny and dry weather in the north is not suitable for the use of dehumidification, on the contrary, a basin of water should be placed in the room to increase the humidity.
4
If the home is used in the fixed frequency air conditioning, it is best not to use the dehumidification function in the high temperature season to replace the refrigeration, one of the high temperature has a greater impact on the compressor, if the dehumidification function is used to make the compressor run intermittently, it is easy to shorten the service life of the compressor.
Only at night when the temperature is relatively low and the humidity is large, the dehumidification mode can be turned on in a timely manner to achieve the effect of adjusting the temperature and humidity of the room.
