Constant Temperature and Humidity Machine GMHW-20F

Constant Temperature and Humidity Machine GMHW-20F

Function and features of Constant Temperature and Humidity Machine GMHW-20F

Typical models: temperature increasing and decreasing, cooling dehumidification, heating dehumidification, constant temperature dehumidification and humidification.
Sealed structure design, with Daikin compressor
Electrical heating and Electrode type humidifier equipped, adequate and surpassed heating capacity. Air conditioner has lower humidify capacity, normally need to choose a larger model or install one more equipment
Easy to drainage: inclination design of the tray, allowing overall drainage without backup
High quality of insulating materials, increase 15% of the insulating effect, low noise, moisture proof
Reliable and safe operation.  Every components is strictly tested in our technical department, long lasting service time
Heat exchanger has Hydrophilic membrane fin with, increase efficiency by 20%
Quiet centrifugal fan, comfort and energy saving

Principle of Constant Temperature and Humidity Machine GMHW-20F

The whole process contains 3 main connected systems: Refrigerant recycling system, Air recycling system and Electrical automatic control system.

Refrigerant cycling system: The liquid refrigerant absorbs the heat in the air and starts to evaporate, thus making the relative temperature difference between the refrigerant and the air. When the liquid refrigerant comes into gaseous form, it is inhaled and condensed in compressor. Then the gaseous refrigerant absorbs heat in the condenser (air cool/water cool) into liquid. Through the throttling process of the expansion valve, it finally becomes liquid refrigerant with low temperature and low pressure. That is the recycling system of refrigerant.
Air recycling system: The air is sucked up into air outlet by the fan. It is transferred into the room where users needed through evaporator (Cooling and dehumidify), humidifier and electric heater (Heating). Then the transferred air mix with the air within the room comes back to the air outlet. That makes the recycling of air.
Electrical automatic control system: This system is made us of voltage and automatic control system separately. Voltage, in simple terms, supply electricity to the compressor, fan, electric heater. Automatic control system can be divided into temperature control, humidity control and malfunction protection.

Application of Constant Temperature and Humidity Dehumidifier

National defense engineering, Civil air defense works,  precision instrument room, Tobacco, Petrochemical industry, Subway station, Aerospace, Purification Project, Laboratory, Computer room, Archives, Food workshops, Pharmaceutical or firm workshops, Special Glass Production, Wood and other occasions needs the control of humidity and temperature.
