Zhongyou Heat Pipe Dehumidifier Unit Series

The operation of the heat pipe dehumidification unit system consists of the internal circulation of the dehumidifier (refrigerant circulation system) and the external circulation of the dehumidifier (air circulation system);

The internal circulation of a dehumidifier: through the operation of the compressor → discharging high-temperature and high-pressure gas from the exhaust port → entering the condenser for cooling → becoming low-temperature and high-pressure gas → intercepting flow through capillary tubes → becoming low-temperature and low-pressure liquid → evaporating and absorbing heat through the evaporator → returning to the compressor to become low-temperature and low-pressure gas, and so on.

External circulation of dehumidifier: under normal startup conditions → through the operation of the fan → humid air is sucked in from the inlet → cooled by the heat pipe to increase the relative humidity of the air → passed through the evaporator → the evaporator adsorbs moisture in the air onto the aluminum sheet → becomes dry air → passed through the heat pipe (→ cooled by the condenser) → blown out from the outlet

1. structural type"personalization"：
There are two types of heat pipe dehumidifiers: with and without a fan. The dehumidification capacity ranges from 8 to 16kg/h, and the unit comes with a fan. For dehumidifiers above 20kg/h, there is no fan, but a standard fan box can be provided separately.

2. Versatile functions:
Dehumidifiers with three functions: heating type, temperature regulating type, and cooling type are provided. Temperature regulating and cooling dehumidifiers also have two cooling methods: water-cooled and air-cooled, which can meet the needs of users in various occasions. Our company can also provide dehumidifiers for special purposes such as low-temperature, low humidity, fresh air, explosion-proof, etc. The low-temperature type is suitable for use in the temperature range of 5 ℃ to 32 ℃ (where the heat pipe dehumidifier does not have a low-temperature unit); Low humidity type is suitable for places where the moisture content of the air in the unit's outlet is required to be 6.5-10.5g/kg dry;; The brand new wind type is suitable for use in situations that require a large enthalpy difference in air treatment;; Explosion proof type is suitable for explosive hazardous areas where combustible gases, vapors, and air are mixed in groups T1-T4 of Class IIA and IIB.

3. Complete range of dehumidification capacity grades:
Heat pipe dehumidification: There are 7 levels of machines ranging from 6kg/h to 63kg/h.

4. Environmentally friendly working fluid, the "green" concept unit adopts R22 refrigerant that meets the requirements of the national plan to phase out CFCs, which is beneficial to the global environment. The company can also customize dehumidifiers using HFC refrigerants such as R134a according to user requirements.

5. The compressor and cold matching compressor adopt fully enclosed compressor or semi enclosed screw compressor (depending on the dehumidification capacity of the unit), and the refrigeration accessories adopt internationally renowned brand products. The unit has low noise and reliable performance. Through scientific and rational optimization design of the refrigeration system, the energy-saving effect of the unit is significant, and the dehumidification capacity per unit input power is much higher than the industry standard.

6. The water side heat exchanger of the heat exchanger adopts a shell and tube heat exchanger, and the air side heat exchanger adopts a copper tube with aluminum fins heat exchanger. It is manufactured using the OAK heat exchanger CNC production line imported from the United States, with high heat transfer efficiency, compact structure, and good pressure resistance. If the user requires other types of heat exchangers, special instructions should be provided.

7. The frame adopts special-shaped steel profiles, and the door panels are cold plate bending parts. EPS sandwich color steel door panels can also be provided according to customer orders. The unit adopts an assembled structure with good universality, clear lines, and beautiful appearance.

8. There are two types of unit control: manual and automatic. Manual control is intuitive, simple, and reliable; Automatic control adopts programmable logic controller (PLC) and human-machine interface (Chinese text display or touch screen) for control, with high degree of automation, low failure rate, and good control accuracy. The automatic control unit can also be equipped with a computer centralized control interface or a remote communication interface, which facilitates the centralized control and remote monitoring of the dehumidifier. If the user needs it, special instructions must be provided; Automatic control is divided into two types: automatic dehumidification and automatic temperature control dehumidification. The automatic dehumidification unit controls the start and stop of the unit based on humidity parameters; Automatic temperature regulation and dehumidification require adjusting the water flow rate (water-cooled type) or adjusting the outdoor fan air volume (air-cooled type) to regulate the temperature. For automatic temperature and humidity control units, as long as the user sets the required temperature and humidity control range, the unit can automatically operate in the humidity priority mode. For situations where temperature priority mode is required, please use our company's constant temperature and humidity air conditioning unit.

9. Optional network functions: The unit can be connected to a remote computer through a modem, and data exchange can be carried out using the Internet to remotely monitor and analyze faults of the unit, helping you quickly and accurately predict and eliminate faults. The group control function of the local area network dehumidifier can also be achieved through the PROFIBUS bus.

10. The system protection system is equipped with multiple protections, such as motor overheating, current overload, refrigeration system overvoltage and undervoltage, fan interlock, overvoltage and undervoltage, power phase loss, delayed start, cooling water cut-off protection, etc., ensuring safe and reliable operation of the unit.
