摘要：
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 degrees 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 degrees C similar to 15 degrees C, which can reduce the exhaust temperature and prevent compressor's overheating. When the exhaust temperature keep at 100 similar to 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.
