Title:
SEMI-OPEN HIGH-TEMPERATURE HEAT PUMP SYSTEM AND WORKING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/184869
Kind Code:
A1
Abstract:
Provided by the present invention is a semi-open high-temperature heat pump system. The system comprises a compressor, a contact condenser, a heat exchanger, an evaporator, a water purifier, a cold water pump, a hot water pump, a circulating water pump and a vacuum pump. An exhaust port of the compressor is connected to the contact condenser. The contact condenser is connected to the evaporator by means of the heat exchanger. The evaporator is connected to an air suction port of the compressor by means of an upper exhaust port. An outlet of the water purifier is separately connected to the compressor, the contact condenser and the evaporator by means of the cold water pump. An outlet below the evaporator is connected to the contact condenser by means of the circulating water pump. The vacuum pump is connected above the contact condenser, and the hot water pump is connected below the contact condenser. The system uses water as the circulating working medium, and uses a contact condenser that has high heat transfer efficiency. The system has the characteristics of environmental protection and high efficiency, and may recover low-temperature waste heat above 50°C, and provide high-temperature hot water above 90°C. Compared to the prior art, the present invention effectively reduces the heat transfer resistance, increases the heat transfer efficiency, efficiently recovers low-temperature waste heat, and improves the quality of the heat source, thereby achieving reuse.
