Working principle of heat pump dryer:
A heat pump is essentially a device for increasing heat. The high-temperature heat pump drying unit uses the reverse Carnot principle to extract heat from the surrounding environment and transfer it to the heated object (a higher temperature object). Its working principle is the same as that of a refrigeration machine, both working according to the reverse Carnot cycle, with the only difference being the operating temperature range. Upgraded to high-temperature thermal energy through a heat pump device; The refrigerant (fluoroaniline) is compressed and converted into high-temperature and high-pressure gas (with a temperature of up to 80-115 ℃), which enters the indoor heat exchanger and uses the heat emitted by the fan to raise the temperature of the air in the drying room. The materials in the drying room are vaporized and evaporated by hot air, and the evaporated water vapor is discharged by the dehumidification system to achieve the purpose of drying the materials.
When the high-temperature heat pump drying unit is working, it absorbs energy from the low-temperature environment medium in the evaporator, just like ordinary air conditioners and heat pump units. QA: It consumes a part of the energy itself, that is, the compressor consumes electricity. QB: When the working fluid circulation system releases heat in the condenser, QC=QA+QB. Therefore, the efficiency of the high-temperature heat pump drying unit is (QB+QC)/QB, while the heating efficiency of other heating devices is less than 1. Therefore, the heating efficiency of the high-temperature heat pump drying unit is much higher than that of other heating devices. It can be seen that using the high-temperature heat pump drying unit as a drying device can save energy, reduce the emission of pollutants such as CO2, and achieve energy-saving and emission reduction effects.
