Summary

The cross defrosting cycle was presented in which one air side heat exchanger defrosts by switching over the corresponding four-way valve and the others operate normally. The experiment of the air side heat exchanger cross defrosting was conducted on an air to water heat pump using a screw compressor with a refrigerating capacity of 359 kW. The results show that the discharge temperature of the unit was at a normal range and the suction pressure rose slightly. Moreover, the heating time was longer and the comprehensive EER improved greatly.
