The third type of thermally driven compression heat pump

Abstract

The invention provides a third type of heat-driven compression heat pump, which belongs to the technical field of power, refrigeration and heat pumps. The low-temperature condenser has a circulating working medium channel that communicates with the evaporator through a booster pump; the high-temperature condenser has a circulating working medium channel that communicates with the evaporator through a throttle valve; the evaporator also has a circulating working medium channel that communicates with the high-temperature condenser through a compressor , the high-temperature condenser also has a circulating working medium channel that communicates with the high-temperature heat exchanger through the second booster pump, the high-temperature heat exchanger also has a circulating working medium channel that communicates with the low-temperature condenser through the expander, and the evaporator also has a low-temperature heat medium channel It communicates with the outside, the high-temperature condenser also has a heated medium channel to communicate with the outside, the high-temperature heat exchanger also has a high-temperature heat medium channel to communicate with the outside, and the low-temperature condenser also has a cooling medium channel to communicate with the outside, and the expander is connected to the compressor and transmits power, forming the 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...

Problems solved by technology

However, due to the influence of the nature of the working medium (solution and refrigerant medium), it is impossible to realize the conversion of thermal energy into mechanical energy while supplying heat, and its application field and application range are greatly limited.
