Multi-directional thermodynamic cycle and third-type thermal driving compression type heat pump

Abstract

The invention provides multi-directional thermodynamic cycle and a third-type thermal driving compression type heat pump, and belongs to the technical fields of power, refrigeration and heat pumps. The multi-directional thermodynamic cycle and the third-type thermal driving compression type heat pump are characterized in that the temperature difference between a high temperature heat source and a middle temperature heat source and the temperature difference between a low temperature heat source and a secondary low temperature heat source are adopted as the driving temperature difference, and a working medium performs multi-directional thermodynamic cycle; a compressor has a circulating working medium channel which communicates with an expansion machine through a high temperature heat exchanger; the expansion machine has a circulating working medium channel which communicates with a second expansion machine through a heat supply device; the second expansion machine has a circulating working medium channel which communicates with a second compressor through a cooler; the second compressor has a circulating working medium channel which communicates with the compressor through a low temperature heat exchanger; the high temperature heat exchanger has a high temperature thermal medium channel; the heat supply device has a heated medium channel; the cooler has a cooling medium channel; the low temperature heat exchanger has a low temperature thermal medium channel communicating with the exterior; and the expansion machine and the second expansion machine are connected with the compressor and the second compressor to transmit power and form the third-type thermal driving compression type 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] 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...
