Energy saving heat pump vegetable drying room

Vegetable drying room

 Equipment Introduction

Heat pump is essentially a heat lifting device, high-temperature heat pump drying unit using the inverse Carnot principle, from the surrounding environment to absorb heat, and transfer it to the object being heated. The high temperature heat pump drying unit is composed of fin evaporator (external), compressor, fin condenser (internal) and expansion valve. The thermal cycle of evaporation, compression, condensation, throttling and re-evaporation can be completed by the refrigerant. Loop process, so that the external low-temperature environment of the heat transfer to the drying room, refrigerant is recycled under the action of compressor in the system. It completes the rising temperature and pressure processing in gaseous state. Then release the heat in drying room to dry the raw material and return back to liquid state, when it runs to the evaporator (external), it will adsorb the environment heat and become gas state .

Work Principle

1.Compression process: The low temperature and low pressure refrigerant gas is compressed by the compressor into a high temperature and high pressure gas. At this time, the work done by the compressor is converted into the internal energy of the refrigerant gas, so that the temperature rises and the pressure increases, and the thermodynamics is called an adiabatic process.

2.Condensation process: The high-temperature and high-pressure refrigerant gas coming out of the compressor flows through the condenser and is continuously released to the outside by the wind or water, and is condensed into a medium-temperature high-pressure refrigerant liquid. The refrigerant temperature decreases but the pressure does not change during liquefaction, which is thermodynamics called an isobaric process.

3.Throttling process: The medium-temperature high-pressure refrigerant liquid from the condenser is thawed by the throttling device and becomes a low-temperature low-pressure refrigerant liquid. In thermodynamics, it is called an isenthalpic process.

4.Evaporation process: The low-temperature and low-pressure refrigerant liquid from the over-throttle device flows through the evaporator, and continuously absorbs heat into the room by wind or water, and evaporates into a low-temperature low-pressure refrigerant gas. The absorbed heat becomes the latent heat of the refrigerant, although the temperature rise is not large, but the internal energy increases a lot. Since the pressure does not change much, it is thermodynamically called an isobaric process.
