Working principle
The air source High-temperature heat pump dryer adopt reverse carnot principle to absorb the heat of air and transfer it to the room, to increase the temperature of drying room, to achieve the drying of materials article.
It consists of compressor-heat exchanger-Electric expansion valve(throttle)-Evaporator constitute a circulation system.The refrigerant circulates in the system under the action of compressor, It completes the gaseous boosting process in the compressor (temperature up to 100 °C), it enters the internal machine to release high-temperature heat to heat the air in the drying room, while being cooled and converted into a liquid liquid, when it runs to the outside machine After that, the liquid rapidly absorbs the heat and evaporates again into a gaseous state, and the temperature drops to minus 20 ° C - 30 ° C, at which time the air around the heat sink will continuously transfer heat to the refrigerant. The continuous circulation of the refrigerant realizes the transfer of the heat in the air to the temperature of the air in the heating room in the drying room.
Advantage of High temperature heat pump dryer
1、Economic benefit
2、Safety and environmentally friendly
By transferring the heat in the air to the drying room for drying purposes, only the amount of heat that is transferred is consumed. There is no need to consume other fuels, that is, to avoid safety and environmental pollution problems in transportation and storage fuels. No pollutants are produced during the operation.
3、Good effect
With automatic control System, the state of the unit's operation can be automatically adjusted according to the setting mode. Stable and uniform rise The temperature, less temperature difference fluctuates, Precise controlled temperature difference at ±0.5 ℃ to avoid the influence of human factors on the drying quality during the operation of the fuel dryer.
