Problems solved by technology
[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit
Compression heat pump technology that utilizes the grade difference between mechanical energy and thermal energy has certain flexibility, but in many cases it is difficult to achieve efficient utilization of thermal energy
At the same time, the two technologies also have a common deficiency - they cannot convert thermal energy into mechanical energy while heating or cooling

The invention provides a first type of heat-driven compression heat pump, which belongs to the technical field of power, refrigeration and heat pumps. The outside has an air passage connected to the compressor, the compressor also has a compressed air passage connected to the combustion chamber, the combustion chamber has a fuel passage connected to the outside, the combustion chamber has a gas passage connected to the gas turbine, and the gas turbine has a gas passage through high-temperature heat exchange The second compressor communicates with the outside, the second compressor communicates with the expander through the high-temperature heat exchanger, the expander also communicates with the second expander through the heat supply, and the second expander also communicates with the circulated medium channel The low-temperature heat exchanger communicates with the second compressor, the heater and the channel of the heated medium communicate with the outside, the low-temperature heat exchanger also communicates with the outside of the low-temperature heat medium channel, and the gas turbine, the expander and the second expander are connected to the compression machine and the second compressor and transmit power to form the first type of heat-driven compression heat pump.
Description
Technical field: [0001] The invention belongs to the technical field of power, refrigeration 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] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit. Compression heat pump technology, which utili...
