Unit Overview:

Dehumidifier is a series of refrigeration and dehumidification equipment developed by our company based on years of experience in designing and manufacturing refrigeration dehumidifiers to remove moisture from the air. It is suitable for places with dehumidification requirements such as national defense engineering, civil defense engineering, tobacco and petrochemical industries, subway stations, aerospace fields, purification engineering, laboratories, telecommunications equipment rooms, archives, food rooms, pharmaceutical or film workshops, and special glass manufacturing.

working principle:

The operation of a conventional dehumidifier system consists of the internal circulation of the dehumidifier (refrigerant circulation system) and the external circulation of the dehumidifier (air circulation system);

Internal circulation of dehumidifier: through the operation of compressor→The exhaust outlet discharges high-temperature and high-pressure gas→Enter the condenser for cooling→Become a low-temperature and high-pressure gas→Cut off flow through capillary tube→Becoming a liquid with low temperature and pressure→Evaporate and absorb heat through an evaporator→Returning to the compressor, it becomes a low-temperature and low-pressure gas, and this cycle repeats itself.

External circulation of dehumidifier: under normal startup conditions→Through the operation of the fan→Moist air is drawn in through the air inlet→After passing through the evaporator→The evaporator adsorbs moisture from the air onto the aluminum sheet→Turn into dry air（→After passing through the condenser for heat dissipation→Blow out from the air outlet.

Unit characteristics:

1. Diverse structural types:
Conventional dehumidifiers come with built-in fans, which are easy to install and can be divided according to the air inlet and outlet methodsaFront return air (grille return air), front outlet air (hood supply air),bRear return air (flange return air), top outlet air (flange supply air),cThere are three types of front return air (grille return air) and top outlet air (flange supply air).

2. Fully functional:
Conventional dehumidifiers have three types of functions: heating type, temperature regulating type, and cooling type. Among them, heating dehumidifiers are mainly used for dehumidification and do not have cooling function, so they are suitable for dehumidification places without temperature requirements; The temperature regulating dehumidifier integrates dehumidification and cooling functions, and its cooling capacity is adjustable, making it particularly suitable for dehumidification places with large changes in thermal load. A cooling dehumidifier has a cooling function while dehumidifying, but its cooling capacity cannot be adjusted, making it suitable for dehumidification situations with high heat loads and no requirements for relative humidity.

3. Compressor and Cold Distribution:
The compressor and main refrigeration components are all products from internationally renowned brands. Through scientific and rational optimization design of the refrigeration system, the unit has low noise, reliable operation, and high energy efficiency.

4. Heat exchanger:
The water side heat exchanger is a shell and tube heat exchanger, using high-efficiency heat exchange tubes; The air side heat exchanger is a copper tube covered aluminum fin heat exchanger, which is imported from the United StatesOAKManufacturing of heat exchanger CNC production line. The heat exchanger has a compact structure, good pressure resistance, and high heat transfer efficiency.

5. Environmentally friendly working fluid,'green'Concept: The unit is designed to meet the requirements of eliminationCFCThe national program for working fluids requiresR22Refrigerants are beneficial to the Earth's environment. The company can also customize according to user requirementsR407c、R134aclassHFCDehumidifier with working fluid.

6. Shell:
The unit adopts the popular high-strength aluminum profile frame at home and abroad; The bent parts are made in JapanAMADACNC equipment processing has excellent appearance quality. The unit adopts an assembled structure, which is compact, aesthetically pleasing, and highly modern.

7. Control method:
The heating dehumidifier and cooling dehumidifier are controlled by professional microcomputers, and the unit can automatically start and stop according to the user's set relative humidity or temperature.

8. The temperature regulating dehumidifier adopts a high-performance programmable controller（PLC）Controlled with a Chinese text display, it has good reliability and high control accuracy. As long as the user sets the required temperature and humidity control range, the unit can automatically operate in the humidity priority mode.

9. Optional network functions:
The crew can pass throughPROFIBUSThe bus realizes the group control function of the local area network dehumidifier, and can also connect the device to a remote computer through a modem or Ethernet moduleINTERNETPerform data exchange, remote monitoring and fault analysis of the unit to help you quickly and accurately predict and troubleshoot faults.

10. Multiple protections:
The unit is equipped with overload, short circuit, phase loss, overheating, high voltage, low voltage protection, as well as interlocking protection for fans, water pumps, and fire dampers.
