[Abstract]:In order to improve the operation economy and stability of high temperature heat pump and optimize the flow of high temperature system, the feasibility of applying double screw compressor to high temperature heat pump was verified by setting a heat exchanger economizer in the heat pump system. The experimental results show that it is feasible to apply the gas supply technology to the high temperature heat pump, and the heating capacity of the high temperature heat pump can be effectively increased by using the economizer to replenish the water temperature of the condenser at 88 鈩，
