Heat Pump DryerOperating Principle
A heat pump is essentially a heat boosting device. High-temperature heat pump drying units operate using the reverse Carnot principle, absorbing heat from the surrounding environment and transferring it to the object being heated (a warmer object). Their working principle is similar to that of refrigerators, both working according to the reverse Carnot cycle. The only difference is the working temperature.
High-temperature heat pump dehumidification drying units are mainly composed of four parts: finned evaporator (outdoor unit), compressor, finned condenser (indoor unit), and expansion valve. Through a continuous thermal cycle process of evaporation (absorbing heat from the external environment) → compression → condensation (releasing heat inside the drying room) → throttling → re-evaporation, the heat from the low-temperature external environment is transferred to the drying room, and the refrigerant circulates within the system under the compressor's action. It completes the process of gaseous pressurization and temperature increase (up to 100℃) within the compressor, then releases the high-temperature heat to warm the air inside the drying room, while it cools and becomes a liquid. As it reaches the outdoor unit, the liquid rapidly absorbs heat and evaporates back into a gas, with the temperature potentially dropping to 0℃ to -10℃. At this point, the surrounding air around the heat absorber continuously transfers heat to the refrigerant. The heating efficiency of the high-temperature heat pump drying unit is significantly greater than that of other heating equipment, demonstrating that using a high-temperature heat pump drying unit as a drying device can save energy and reduce CO2 emissions and other pollutants, achieving the effect of energy conservation and emission reduction.
