Now air conditioning has become a necessary electrical appliance. With air conditioning, we will no longer be afraid of the hot summer. But after the air conditioning is used for a long time, the cooling effect will be bad. Do you know what's the matter? What's the difference between air conditioning cooling and dehumidification mode?
What is the difference between air conditioning refrigeration and dehumidification?
Dehumidification of air conditioning needs to be realized by refrigeration. 1、 Same point: no matter refrigeration or dehumidification, when the indoor hot air passes through the heat exchanger of the air conditioner indoor unit, the water vapor in the hot air is condensed into condensate water at low temperature, and the condensate water is discharged to the outdoor through the drain pipe; at the same time, the cold air after heat exchange blows out from the air conditioner outlet. Because air conditioning operation refrigeration mode must remove water vapor at the same time of reducing air temperature; air conditioning operation dehumidification mode must reduce air temperature at the same time of removing water vapor; therefore, whether refrigeration or dehumidification, reducing air temperature and removing water vapor are inseparable.
2、 Difference: Refrigeration: to reduce the air temperature for the purpose of removing water vapor at the same time. Dehumidification: to remove water vapor and reduce air temperature. Refrigeration: 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: select 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.
How does air conditioning refrigeration effect not good return a responsibility?
1. Temperature setting. The cooling effect of the air conditioner is directly related to the temperature of the air conditioner. If the temperature is set high when the air conditioner is turned on in a hot day, the cooling effect of the air conditioner is not good.
2. The air conditioning refrigerant (Freon) is too little or leaks, resulting in the air conditioning working pressure is not enough, resulting in the air conditioning refrigeration effect is not good.
3. The long-term use of air conditioning results in the aging of the internal valve plate of the compressor, resulting in the decline of the transmission power of the compressor, resulting in the poor refrigeration effect of the air conditioning.
4. The air conditioning refrigeration is normal, but the filter screen of the air conditioning has not cleaned the dust for more than half a month, and the dust blocks the filter screen, resulting in the reduction of the circulating air volume, that is, the amount of air-conditioner blown out is not enough, and the refrigeration effect is poor.
After the air conditioner has been used for a long time, it is inevitable that some aging will occur, which will cause some problems in the refrigeration, dehumidification and other functions of the air conditioner. But the refrigeration effect of air conditioning is not good, which we often see when we use air conditioning. The reasons for the poor cooling effect of the air conditioner are almost the same. Here's a supplement. Too much room space will also affect the cooling effect of the air conditioner, so we'd better decide where to install according to the specifications of the air conditioner. Also, do not place too many obstacles at the air outlet, which will also affect the cooling effect of the air conditioner.
