How does a refrigerating dehumidifier work?
Author:
The refrigerating dehumidifier is also the dehumidifier that we often use every day. The reason why it is called a refrigerating dehumidifier is because it has a lot to do with its working principle. It reduces the temperature by liquefying the water vapor in the air. The water vapor content in the air, so it is professionally called a refrigerated dehumidifier. In the rainy season, a dehumidifier is very necessary to avoid physical discomfort caused by excessive humidity. Its working principle is relatively simple. The following is the relevant introduction.
The working principle of refrigerating dehumidifier
The external circulation of the refrigerating dehumidifier is divided into three processes. The first process is to suck the humid air at room temperature into the machine through the fan, and the second process is to suck in the water vapor in the humid air at normal temperature through the evaporator. (cooling copper tubes and fins) liquefy into water droplets and discharge through a hose. The third process is that the dry air cooled by the evaporator then goes through the condenser (high temperature copper tubes and fins) to warm up to normal temperature and is discharged through the air outlet. In this way, the air is dehumidified. The whole process also follows the law of conservation of energy, and the air also goes through a cycle process of normal temperature-low temperature-normal temperature, which is also a process of energy conversion.
work process
Refrigeration dehumidifier is mainly composed of evaporator, condenser, compressor, expansion valve, fan and casing. When it is working normally, the evaporator can absorb the heat in the external environment. According to the principle of energy conservation, its condensation The evaporator will also release heat to the external environment. Under the action of the fan, the moist air will be inhaled from the air inlet on the left side, and the heat exchange will be carried out through the evaporator to reduce the ambient temperature; when the moist air reaches its dew point temperature, the moisture content It will be precipitated due to condensation, and the absolute moisture content in the humid air will also decrease. When it passes through the condenser again, heat exchange will occur to increase the temperature, thus playing the role of heat preservation and dehumidification.
Internal and external circulation of refrigeration dehumidifier
It is divided into three processes. The first process is to suck the humid air at normal temperature in the space into the machine through the fan, and the second process is to suck the water vapor in the humid air at normal temperature through the evaporator (cooling copper tubes and fins). ) is liquefied into water droplets and discharged through a hose. The third process is that the dry air cooled by the evaporator is then heated to room temperature through the condenser (high temperature copper tube and fins) to be discharged through the air outlet, and so on and so forth. The air is dehumidified. The whole process also follows the law of conservation of energy, and the air also goes through a cycle process of normal temperature-low temperature-normal temperature, which is also a process of energy conversion.
The working principle of the dehumidifier is relatively simple. The process of dehumidification is realized through internal and external circulation. The human body is most likely to cause respiratory diseases in a humid environment for a long time. Therefore, the use of a dehumidifier is very necessary and can be effective. Control the water vapor content in the air to achieve the purpose of drying the indoor environment, especially in the basement or humid room, you must use a dehumidifier, so as not to cause great harm to your health or interior decoration.
