What is the heat pump dryer machine?

The high-temperature heat pump drying unit is mainly composed of four parts: fin evaporator (outside), compressor, fin condenser (inside), and expansion valve. The refrigerant continuously evaporates (absorbs heat from the outdoor environment) → compression → condensation (heat release in the indoor drying room) → throttling → re-evaporation heat cycle process, so as to transfer the heat in the external low-temperature environment to the drying room, and the refrigerant is in the system The circulating flow rate in the compressor under the action of the medium. It completes the gas pressure increase and temperature rise process in the compressor (temperature up to 100°C). It enters the machine and releases high-temperature heat to heat the air in the drying room. At the same time, it is cooled and transformed into a liquid state. When it runs to the outside machine, the liquid quickly absorbs heat and evaporates, and then transforms into a gaseous 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, like ordinary air conditioners and heat pump units, it absorbs the energy in the low-temperature environment in the evaporator.
