Heat Pump DryerOperating Principle
A heat pump is essentially a heat-raising 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 (a warmer object). Its working principle is the same as that of a refrigerator, both operating according to the reverse Carnot cycle; the only difference is the working temperature.
High-temperature heat pump drying and dehumidification unit, mainly composed of finned evaporator (outdoor unit), compressor, finned condenser (indoor unit), and expansion valve. It operates through a thermal cycle of continuous evaporation (absorbing heat from the external environment) → compression → condensation (releasing heat in the indoor drying room) → throttling → re-evaporation. This process transfers heat from the low-temperature external environment to the drying room, with the refrigerant circulating within the system under the compressor's action. It completes the gas-pressure and temperature-rise process (up to 100℃) inside the compressor, then releases the high-temperature heat to warm the air in the drying room while it cools and turns into a liquid state. As it moves to the outdoor unit, the liquid rapidly absorbs heat, evaporates back into a gas, and its temperature can drop to 0℃ to -10℃. At this point, the surrounding air of the heat absorber 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, demonstrating that using the high-temperature heat pump drying unit as a drying device can save energy and reduce CO2 and other pollutant emissions, achieving the effect of energy conservation and emission reduction.
