The manufacturer introduces the maintenance rules of dehumidifier.

Almost everyone who has been exposed to dehumidifiers knows how to use dehumidifiers, but few people know how to maintain dehumidifiers. Today, I will teach you a few maintenance skills. First of all, when we use the dehumidifier, we must set it according to the specific environment around us, and set it to a comfortable humidity.

For example, the relative humidity of the room is about 60%RH, so it is not necessary to adjust it too low, so it is too dry around, which makes people feel dry and uncomfortable, and the use of high load will also affect the life of the dehumidifier. Secondly, we should clean the filter screen of dehumidifier regularly, which can effectively improve the dust removal effect of dehumidifier and improve the surrounding air.

The heat sink of the dehumidifier also needs to be cleaned regularly, so that the dehumidifier can fully dissipate heat, thus improving the use effect of the dehumidifier. If the surrounding environment where the dehumidifier is used is corrosive, it is necessary to buy a dehumidifier made of special anti-corrosion material, so as to avoid serious corrosion of the dehumidifier itself in a short time.

Finally, we also have a regular inspection of the dehumidifier. Machines, like people, need regular inspection to find some potential problems in time and deal with them in time, such as replenishing refrigerant and replacing parts that are about to age, so that the dehumidifier can always be in a good working state.

Analysis on the classification and working principle of dehumidifier

Working principle of dehumidifier: Cooling dehumidifier usually consists of evaporator, condenser, compressor, expansion valve, fan and shell. During normal operation, the evaporator absorbs external heat, and the condenser releases heat outwards. Under the action of the fan, wet air is sucked in from the left air inlet, and it exchanges heat when passing through the evaporator, and its temperature is reduced.

When the wet air reaches the dew point temperature, the moisture is separated out due to condensation, and the absolute moisture content of the wet air decreases, and when it continues to pass through the condenser, heat exchange occurs again to increase its temperature, thus achieving the purpose of heat preservation and dehumidification. Cooling dehumidifier: according to the use function, it can be divided into: general type, cooling type, temperature regulating type and multifunctional type.

A general dehumidifier refers to a dehumidifier in which air is cooled and dehumidified by an evaporator and heated by a reheater to reduce the relative humidity. The condensation heat of the refrigerant is all taken away by the air flowing through the reheater, and the outlet air temperature cannot be adjusted, so it is only used for heating and dehumidifying. Cooling dehumidifier refers to a dehumidifier in which most of the condensation heat of refrigerant is taken away by water-cooled or air-cooled condenser, and only a small part of condensation heat is used to heat the air passing through evaporator, which can be used for cooling and dehumidification.

Temperature-regulating dehumidifier refers to a dehumidifier in which the condensation heat of refrigerant can be taken away in whole or in part by a water-cooled or air-cooled condenser, and the remaining condensation heat is used to heat the air passing through the evaporator, and the outlet air temperature can be adjusted. Multifunctional dehumidifier refers to a dehumidifier that integrates three functions: heating dehumidification (general type), cooling dehumidification and temperature adjustment dehumidification. When there is no outdoor unit (air cooling) or cooling water (water cooling), you can still choose the heating dehumidification function to dehumidify.
