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

Abstract

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 compressor has a circulating working medium channel that communicates with the expander through a high-temperature heat exchanger, the second compressor has a circulating working medium channel that communicates with the expander through a high-temperature heat exchanger, and the expander has a circulating working medium channel that passes through the heater respectively It communicates with the second compressor and the second expander. The second expander also communicates with the compressor through the low-temperature heat exchanger. The high-temperature heat exchanger also communicates with the outside through the high-temperature heat medium channel. There is a heated medium channel communicating with the outside, a low-temperature heat exchanger and a low-temperature heat medium channel communicating with the outside, the expander and the second expander connect the compressor and the second compressor and transmit power, forming 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...
