Working principle of heat pump drying room:
Air-energy heat pump is a heat conversion and lifting device, similar to the working principle of air conditioner. It uses the inverse Carnot principle to absorb heat from the surrounding environment and transfer it to the drying material; the heat pump unit mainly has finned evaporation. It consists of four parts: condenser (outdoor unit), compressor, fin condenser (internal unit) and expansion valve. By allowing the refrigerant to continuously evaporate (absorbing heat from the outdoor environment) → compressing → condensing (released in the indoor drying room) Heat) → throttling → re-evaporation thermodynamic cycle process, so that the heat in the external low temperature environment is transferred to the drying room, and the refrigerant circulates in the system under the action of the compressor. It completes the gaseous boosting and heating process in the compressor. It enters the inner 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 outer unit, the liquid quickly absorbs heat and evaporates. It is converted into gaseous state again, and 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.
 
Application area:
After years of customer feedback and summarization, the main application fields of the current air-energy heat pump drying room are distinguished from the types of materials, which can be divided into mosaic, rhizome, fruit, meat, seafood, fish, food, industrial Types, wood types and some other categories are mainly distinguished from the different forms of drying materials, because the moisture content, thickness, shape and density of the materials will affect the drying process of the air energy heat pump dryer. Better drying materials need to be considered in terms of shape, color and taste. It is precisely because the control of air energy heat pump drying is intelligent that the drying time can be divided into multiple stages, and the control of temperature and humidity in each stage is different. Therefore, air energy heat pump drying rooms are suitable for most 's material. In addition, for the same material, through different drying processes, the drying quality of the finished product is also different.


 
Advantage:
1.High efficiency and energy saving, the thermal efficiency of the air energy heat pump is 4 times that of the traditional electric heating efficiency, which can greatly reduce the cost of drying energy consumption, and is less affected by cloudy and rainy days.
2.Safety and environmental protection. Compared with traditional coal heating, electric heating, steam heating and other drying rooms, the advantages of air energy heat pumps recognized by the majority of users are: the use of full electric operation mode, only water vapor is emitted, and environmental protection zero pollution.
3.Automatic temperature control and humidity control, since the equipment is operated through the intelligent control system, the drying temperature and humidity can be controlled more accurately, so that the same batch of materials can be dried more uniformly, and the color, taste and water content can be maintained at the same level .
4.The maintenance cost is low, the overall equipment structure is simple, there are no wearing parts, the operation is stable, and the use is simple.
