General air conditioners have cooling, heating and dehumidification functions. The working principle is very similar: the compressor and refrigerant pass through the evaporator and condenser to make the indoor air cool or warm. We know that when the air conditioner is cooled, the indoor air will become quite dry, and the water pipe of the outdoor unit will continue to drip. That is because the moisture in the indoor air encounters a sharp drop in the temperature of the evaporator, liquefies into water droplets, and is discharged outside through the pipe. This leads to a decrease in indoor humidity.
Air conditioning dehumidification is similar to refrigeration, and both use the above principles. But the program control of the two is different. The control of refrigeration is based on whether the indoor air temperature reaches the set temperature. As long as it is not reached, it will continue to work until it is reached. In the dehumidification state, the compressor responsible for refrigeration does not work continuously, but dehumidifies intermittently, so that the indoor temperature is not as severe as cooling.
There are many types of dehumidifiers, among which refrigerated dehumidifiers are the most commonly used. The dehumidification principle of a refrigerated dehumidifier is the same as that of an air conditioner. The humid air passes through an evaporator with a very low temperature, and when it meets cold, it is liquefied into water droplets and collected in a water tank. Although the principles are the same, the structure is different. The air conditioner consists of two fans, while the dehumidifier has only one fan. After the humid air is dried, it needs to pass through a high-temperature condenser. Therefore, the temperature of the air blown out is close to the room temperature, which cannot reduce the indoor temperature.
So, is the value of the dehumidifier worth buying?
Regardless of whether it is an air conditioner or a dehumidifier, the principle of dehumidification uses the physical phenomenon of liquefaction of moist air when it meets cold. The difference is that the purpose of the air conditioner is to lower the temperature. While lowering the temperature, it can play a certain dehumidification effect; the dehumidifier only Can be used for dehumidification, but cannot change the indoor temperature.
The air conditioner can both refrigerate and dehumidify, but the dehumidifier can only dehumidify but not cool. Is it not worth buying a dehumidifier?
The answer is of course no. Yes, air conditioners are more widely used, but there are specialties in the technical industry. When air conditioners are used for dehumidification, the electricity cost will not be mentioned (generally, the power of air conditioners exceeds 900W, while the power of dehumidifiers is only 300W). One third of the humidifier), and the dehumidification process will continue to blow out cold wind (in humid weather blowing cold wind will make people feel uncomfortable), and more importantly, it cannot be moved (the dehumidifier can be moved to the bathroom for use). Therefore, the dehumidifier is definitely worth buying!
The dehumidifier is specially used for dehumidification, which is silent and energy-saving, and the dehumidification effect is obvious, and it can accurately control the humidity to ensure that the air is dry and comfortable. Moreover, the dehumidifier can be moved, and you only need to buy a dehumidifier to meet the needs of the entire house. Some dehumidifiers even have a certain waterproof capacity, even if they are used in the bathroom.
