Working principle of heat pump dryer
The heat pump is essentially a kind of heat lifting device. The high temperature heat pump dryer uses the inverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object (the object with higher temperature). Its working principle is the same as that of the refrigerator, and it works according to the inverse Carnot cycle, but the working temperature range is different.
The high-temperature heat pump drying unit mainly consists of four parts: fin evaporator (external machine), compressor, fin condenser (internal machine) and expansion valve. The heat cycle process of evaporation (absorbing the heat in outdoor environment) 鈫?compression 鈫?condensation (releasing the heat in indoor drying room) 鈫?throttling 鈫?re evaporation is completed by the working medium, so as to reduce the heat in external low-temperature environment Transfer to the drying room, the refrigerant circulates in the system under the action of the compressor. It completes the process of gas pressure rise and temperature rise in the compressor (the temperature is as high as 100 鈩?. It enters the internal machine and releases high temperature heat to heat the air in the drying room. At the same time, it is cooled and transformed into liquid flow. When it runs to the external machine, the liquid rapidly absorbs heat and evaporates again into gas state. At the same time, the temperature can drop to - 20 鈩?~ - 30 鈩? at this time, the air around the heat absorber will not be supplied The heat is transferred to the refrigerant without interruption.
Integration is to use the evaporator of the heat pump high temperature drying unit to absorb the heat in the external environment (air), or to recover the exhaust heat during the drying process. After the work of the compressor, the high-temperature and high-pressure energy is transferred to the drying constant temperature room, and the heat is released through the condenser in the drying constant temperature room. The hot air in the drying constant temperature room is heated by repeated circulation to absorb materials Through the hot air drainage or condensation process, the moisture in the material is discharged and recycled continuously, and finally the continuous drying of the material is realized.
When the high-temperature heat pump drying unit is working, it absorbs the energy in the medium of low-temperature environment in the evaporator, like the common air conditioner and heat pump unit. QA: it consumes part of the energy itself, that is, the power consumption of the compressor QB: it releases the heat through the working medium circulation system in the condenser, QC = QA + QB, so the efficiency of the high-temperature heat pump drying unit is (QB + QC) / QB, while the addition of other heating equipment The thermal efficiency is less than 1, so the heating efficiency of the high-temperature heat pump dryer is much higher than that of other heating equipment. It can be seen that using the high-temperature heat pump dryer as the drying device can save energy, reduce the emission of CO2 and other pollutants, and achieve the effect of energy conservation and emission reduction.Side Air Dryer
