Dongjing Temperature Regulating Dehumidifier DJFT-3881E

The Dongjing temperature regulating dehumidifier has two modes: dehumidification and air conditioning. Dehumidification mode is suitable for situations where the ambient temperature is low, while air conditioning mode is suitable for situations where the ambient temperature is high and cooling is required. In dehumidification mode, users can also adjust the temperature of the exhaust air as needed to achieve functions such as cooling dehumidification, heating dehumidification, and constant temperature dehumidification. The refrigeration system has a reasonable structure, good air tightness, high reliability, and is easy to install and use.

working principle

◇ Internal circulation: Through the operation of the outdoor compressor → discharge high-temperature and high-pressure gas from the exhaust port → enter the condenser for cooling → become low-temperature and high-pressure gas → be intercepted by the capillary tube (expansion valve) to become low-temperature and low-pressure liquid → enter the indoor host evaporator through the connecting pipe for evaporation and heat absorption → return to the compressor to become low-temperature and low-pressure gas! This cycle repeats itself.

◇ External circulation: Under normal startup conditions → through the operation of the fan → moist air is sucked in from the inlet → passes through the evaporator → the evaporator adsorbs moisture in the air onto the aluminum sheet to become dry air → blows out from the outlet.

air coolingTemperature regulating dehumidifierIt is to regulate the temperature by discharging heat to the outside through an external unit (water-cooled temperature regulating dehumidifier takes away heat through condensed water).

Occasions for use

National defense engineering, civil defense engineering, tobacco and petrochemical industries, subway stations, aerospace fields, purification engineering, laboratories

Telecommunications equipment room, archive room, food room, pharmaceutical or film workshop, special glass manufacturing, etc

The Dongjing temperature regulating dehumidifier adopts a compressor and heat exchanger, with a small overall volume, light weight, low energy consumption, and high efficiency.
◇dehumidifierFor automatic control type, there are mechanical control type and microcomputer control type. Microcomputer controlled type, automatically displays relative humidity through key input, automatically turns on or off, and performs automatic detection and control based on the humidity set by the user.
