The invention provides a third-type thermally-driven compression heat pump, and belongs to the technical field of power, refrigeration and heat pumps. A compressor comprises a cycle working medium channel which communicates with a second compressor and an expansion machine after passing through a low-temperature heat exchanger. The expansion machine further comprises a cycle working medium channel communicating with a cooler. The second compressor further comprises a cycle working medium channel communicating with a third compressor through a heat supply device. A third compressor further comprises a cycle working medium channel communicating with a second expansion machine through a high-temperature heat exchanger. The second expansion machine further comprises a cycle working medium channel communicating with the cooler. The cooler further comprises a cycle working medium channel communicating with the compressor. The low-temperature heat exchanger further comprises a low-temperature thermal medium channel communicating with the exterior. The heat supply device further comprises a heated medium channel communicating with the exterior. The high-temperature heat exchanger further comprises a high-temperature thermal medium channel communicating with the exterior. The cooler further comprises a cooling medium channel communicating with the exterior. The expansion machine and the second expansion machine are connected with the compressor, the second compressor and the third compressor and transmit power. The third-type thermally-driven compression heat pump is formed.
Description
Technical field: [0001] The invention belongs to the technical field of power, heat supply and heat pump. Background technique: [0002] Cold demand, heat demand and power demand are common in human life and production; in reality, people often need to use high-temperature heat energy to achieve cooling, heating or conversion into power, and also need to use power for cooling or use power combined Low temperature thermal energy for heating. In the process of achieving the above goals, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user needs, ambient temperature, type of working medium, equipment flow, structure and Manufacturing costs and more. [0003] The thermal energy (temperature difference) utilization technology represented by absorption heat pump technology can simultaneously utilize the temperature difference between the medium-temperature heat load and the cold environment and t...
