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

Abstract

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

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
