Heat pump operating principle
High-temperature heat pump unit has four main parts, which are the compressor, condenser, throttling device and evaporator.
1. The medium running in the system, in the evaporator, draws heat from the air, evaporates from low-pressure liquid workmass into low-pressure steam, which is pressurized by the compressor to become high-temperature, high-pressure steam.
2. in the condenser, high temperature and high pressure of the mass of steam to release heat, and the mass itself from the gas condenses into a high-pressure liquid; through the throttle device, the liquid mass produces a blocking effect, reduces the pressure and temperature into a low-pressure low-temperature liquids, and again into the evaporator to absorb the heat in the air.
So the repeated cycle of low-temperature heat transfer to high-temperature media, the formation of heat pump cycle. The so-called "heat pump", is to consume a certain amount of mechanical power, absorb the environment or waste in the low-grade heat energy, . Upgrade it into a kind of energy-saving device that can be utilized heat energy.
In the low-temperature dehumidification system and full-effect dehumidification system, the drying medium is circulated in the closed space, which will not be affected by the external climatic conditions, and it can run smoothly all year round, with remarkable energy-saving effect and large single processing capacity. Moreover, the whole system is intelligently controlled, the humidity and temperature of the product, the character and color can be automatically adjusted, and the drying effect is very good.
