The invention provides a multi-directional thermodynamic cycle and a third-type heat-driven compression heat pump, belonging to the technical fields of power, refrigeration and heat pumps. The temperature difference between the high-temperature heat source and the medium-temperature heat source and the temperature difference between the low-temperature heat source and the sub-low temperature heat source are used as the driving temperature difference, and the working medium performs a multi-directional thermodynamic cycle; the compressor has a circulating working medium channel that communicates with the expander through a high-temperature heat exchanger. The expander has a circulating working medium channel that communicates with the second expander through the heat supplier, the second expander has a circulating working medium channel that communicates with the third expander through a low-temperature heat exchanger, and the third expander has a circulating working medium channel that is cooled The high-temperature heat exchanger has a high-temperature heat medium channel, the heater has a heated medium channel, the low-temperature heat exchanger has a low-temperature heat medium channel, and the cooler has a cooling medium channel to communicate with the outside respectively. The second expander and the third expander are connected to the compressor and transmit power to form a third type of heat-driven compression heat pump.
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...
