Open type bidirectional thermal cycle and second kind thermal driving compression heat pump

Abstract

The invention provides an open type bidirectional thermal cycle and second kind thermal driving compression heat pump, and belongs to the heat energy utilization and heat pump technical field; a boost process 12 of a cold source medium from low temperature, a heat release process 23 to a high temperature heat source, a pressure reduction process 34 from high temperature, a heat absorption process 45 from a middle temperature heat source and a pressure reduction process 56 from middle temperature can form open type bidirectional thermal cycle; an external cold source medium channel is connected with a compressor; the compressor uses the cold source medium channel to connect with an expander through a heater; the expander uses the cold source medium channel to connect with a second expander through a heat exchanger; the second expander is connected with the outer side through the cold source medium channel; the heater is connected with the outer side through a heated medium channel; the heat exchanger is connected with the outer side through a middle temperature medium channel; the expander and the second expander are connected with the compressor so as to transfer power, thus forming the second kind thermal driving compression heat pump.

Description

Technical field: [0001] The invention belongs to the technical field of power, heat supply and heat pump. Background technique: [0002] Heat demand and power demand are common in human life and production. The higher the temperature of thermal energy, the higher the possibility of its utilization and the more convenient it is to utilize. In reality, for the heat load with lower temperature, people need to adopt the necessary technology to raise its temperature. 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 heat energy (temperature difference) utilization technology represented by absorption heat pump technology uses the temperature difference between the heat load and the cold environment to increase the temperatur...

Problems solved by technology

[0003] The heat energy (temperature difference) utilization technology represented by absorption heat pump technology uses the temperature difference between the heat load and the cold environment to increase the temperature of part of the heat load; however, due to the nature of the working medium (solution and refrigerant medium), It is also impossible to realize the conversion of thermal energy to mechanical energy while supplying heat, and its application field and application range are greatly limited.
