High Temperature Heat Pump

In this paper，a high temperature heat-pump dryer and a corresponding semi-enclosed test drying room for using the dryer are built up respectively. While the average dry bulb of the external environment is 25°C and the relative humidity is 55%, the performance of the dryer is obtained when the dryer is running continuously for five hours. The results show that: the electromagnetic valve-capillary institution has an obvious effect on the lower the dryer exhaust temperature. It makes the suction temperature of compressor dropped 10 °C~15 °C, which can reduce the exhaust temperature and prevent compressor’s overheating. When the exhaust temperature keep at 100~110 °C, it can not only guarantee the temperature of wind coming from the dryer is high, but also can make sure the drying system’s long-term stable operation.
