Working principle of heat pump dryer

The heat pump dryer uses the reverse Carnot principle to absorb the heat of the air and transfer it to the warehouse to increase the temperature of the drying room, and cooperate with the corresponding equipment to realize the drying of the material. The heat pump dryer consists of a compressor-heat exchanger (inner unit)-throttler-heat absorber (outer unit)-compressor and other devices to form a cycle system. The refrigerant circulates in the system under the action of the compressor.Heat treatment process of gear vacuum carburizing and quenching It completes the gaseous boosting and heating process in the compressor (temperature up to 100°C), it enters the internal machine and releases high-temperature heat to heat and dry the air in the room, and at the same time it is cooled and transformed into a liquid state, when it runs outside After cooling down,Deformation correction of 20CrMo steel plate by vacuum carburizing and quenching the liquid state quickly absorbs heat and evaporates and turns into a gaseous state again, and at the same time the temperature drops to minus 20°C - 30°C. At this time, the air around the heat absorber will continuously transfer heat to the refrigerant. The continuous circulation of the refrigerant can transfer the heat in the air to the drying room to heat the air temperature in the room.HD700-3D/HD1000-3D/HD1250-3D HIGH SPEED 3D CNC BEAMS DRILLING LINE It adopts embedded installation and is integrated with the warehouse, which is easy to install and easy to maintain. It adopts the design of multi-fan and large air volume, which can provide even air supply and better drying effect.D SERIES CNC DRILLING MACHINE FOR PLATES
