introduce
A heat pump is essentially a device for increasing heat. The high-temperature heat pump drying unit utilizes the reverse Carnot principle, uses a small amount of electrical energy, and uses a compressor to evaporate the working fluid through an expansion valve into a gaseous state in the evaporator, and absorbs a large amount of heat from the surrounding environment. The gaseous working fluid is compressed by the compressor into a high-temperature and high-pressure gas, which then enters the condenser to release heat and transfer it to the heated object (high-temperature object). This continuous cycle of heating can heat the drying medium to 40 ℃~85 ℃℃. Compared to electric drying machines, it saves two-thirds of electricity,Its working principle is opposite to that of a refrigeration machine, both working according to the reverse Carnot cycle principle. The difference between the two is that the former increases the temperature while the latter decreases it.

working principle
The high-temperature heat pump drying unit mainly consists of four parts: a finned evaporator (external unit), a compressor, a finned condenser (internal unit), and an expansion valve. By continuously evaporating the working fluid (absorbing heat from the outdoor environment), compressing, condensing (releasing heat in the indoor drying room), throttling, and re evaporating, the heat from the external low-temperature environment is transferred to the drying room. The refrigerant circulates in the system under the action of the compressor. It completes the process of gas pressure rise and temperature rise (up to 100 ℃) inside the compressor. It enters the internal unit and releases high-temperature heat to heat the air in the drying room. At the same time, it is cooled and converted into a liquid state. When it runs to the external unit, the liquid state quickly absorbs heat and evaporates back into a gas state. At the same time, the temperature can drop to -20 ℃~-30 ℃. At this time, the air around the heat absorber will continuously transfer heat to the refrigerant. 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.
