Heat Pump DryerOperating Principle

A heat pump is essentially a heat boosting device. High-temperature heat pump drying units utilize the reverse Carnot principle to absorb heat from the surrounding environment and transfer it to the object being heated (an object with a higher temperature). Their working principle is the same as that of refrigeration units, both operating according to the reverse Carnot cycle. The only difference is the working temperature.

High-temperature heat pump drying and dehumidification unit, primarily composed of four parts: finned evaporator (outdoor unit), compressor, finned condenser (indoor unit), and expansion valve. It operates through a thermal cycle where the working fluid continuously undergoes evaporation (absorbing heat from the external environment) → compression → condensation (releasing heat indoors in the drying room) → throttling → and re-evaporation. This transfers heat from the cold external environment to the drying room, while the refrigerant circulates within the system. It completes a gas-to-liquid phase change and pressure increase process (temperature up to 100℃) within the compressor. It then releases the high-temperature heat to warm the air in the drying room, while it cools and becomes a liquid. As it flows to the outdoor unit, the liquid rapidly absorbs heat and evaporates back into a gas, potentially lowering the temperature to 0℃ to -10℃. At this point, the surrounding air continuously transfers heat to the refrigerant. The heating efficiency of the high-temperature heat pump drying unit is significantly higher than that of other heating equipment, making it an energy-saving choice for drying systems. It also reduces CO2 emissions and other pollutants, achieving the effect of energy conservation and emission reduction.

High-Speed High-Temperature Heat Pump Dryer (Intelligent Combination of Drying and Dehumidification) Features

1The quick-drying heat pump dryer is an integrated intelligent device that combines dehumidification, heating, cooling, temperature exhaust, and ventilation, serving as a new type of energy-saving and emission-reduction drying equipment.

2Utilizing a dual-effect dehumidification technology in the intermediate heat exchange dehumidification process significantly enhances the dehumidification performance ratio and delivers notable energy-saving effects.

3Breakthrough traditional dehumidifier and common heat pump dehumidification dryer technology bottlenecks: Solve the technical problem of poor dehumidification performance or even idling (compressor running without removing water) of traditional dehumidification equipment under high temperature and low humidity conditions.

4Energy-saving exhaust air heat recovery design: Reduces heat loss in emissions, with better overall energy efficiency.

5The pre-dehumidification function of the fresh air system ensures the incoming fresh air is dry, suitable for strict drying processes.

6The Quick-Dry High-Temperature Heat Pump Drying Machine is an environmentally friendly and energy-saving drying equipment. It does not produce any harmful substances during the drying process, and there is no smoke or open flame. It can adjust the temperature and humidity according to the characteristics of the drying material and boasts high intelligence.

7The drying process does not require constant supervision. Once the material is dried or the drying temperature is reached, the machine will automatically shut off to achieve energy-saving effects. The unit operates under normal temperature and pressure, with its energy-saving feature being particularly evident. Its energy-saving efficiency is superior to that of electric heating tubes, infrared, and microwave ovens.50%Above, more energy-efficient than burning oil40%Energy-efficient compared to coal burning20%--30%During the drying process, the unit generates cold air, which, when directly exhausted into the work area, can increase the room temperature.
