1. General
1.1 Application
Cabinet-type dehumidification equipment adopts direct evaporative cooling design, which can dr y the air
under atmospheric pressure. The dehumidification equipment can dehumidify the air with a temperature range of
5°C to +35°C within 100% relative humidity.It is widely used in hotels, office buildings, hospitals, commercial and
residential, scientific research institutions and other places.
The cabinet-type dehumidifier can work normally in the following temperature range.It will not work normally
outside this range, which is not a quality problem of the equipment itself.

2.1 Introduction
The design of the dehumidifier meets the requirements of the IEC protection level IP 45.
2.2 Working Principle
（Figure 1）
The internal circulation of the dehumidifier : through the operation of the compressor → discharge high
temperature and high pressure gas from the exhaust port → enter the condenser for cooling → It becomes
a low-temperature and high-pressure gas → intercepted by a capillar y tube → becomes a low-temperature
and low-pressure liquid → vaporizes and absorbs heat through an evaporator → back The compressor
becomes a low-temperature and low-pressure gas.
（Figure 2）
External circulation of dehumidifier : It uses a refrigerator to dehumidify with a ventilation system.
Compared with other dehumidification methods (heating dehumidification, ventilating dehumidification,
adsorption dehumidification), it is characterized by stable , reliable, and continuous performance. The
working principle is the fan draws warm & humid air through the refrigerated evaporator(cooling coil). The
air is cooled well below its dew point: tempearature decreases and moisture removed.The water condenses
on the cold surface of the evaporator and drips into a water container(and then flows by gravity into drain
pipe) or is led directly to a drain. Then, the cold dr y air continues through a hot condenser which heats it up
and returns it to the room to pick up new humidity. This procedure is continued until the desired condition
is achieved.
