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 fields of power, refrigeration and heat pump. The evaporator has a circulating working fluid channel which is connected to the high temperature heat exchanger through the second booster pump, the high temperature heat exchanger also has a circulating working fluid channel which is connected to the high temperature condenser through the expander, and the evaporator also has a circulating working fluid channel which is connected to the high temperature condenser through the compressor. The condenser, the high-temperature condenser and the circulating working fluid channel are connected to the evaporator through the throttle valve, the high-temperature condenser and the circulating working fluid channel are connected to the low-temperature condenser through the second expander, and the low-temperature condenser and the circulating working fluid channel are connected to the low temperature condenser. The pressure pump communicates with the evaporator, the high temperature heat exchanger and the high temperature heat medium channel communicate with the outside, the high temperature condenser and the heated medium channel communicate with the outside, the low temperature condenser and the cooling medium channel communicate with the outside, and the evaporator also has a low temperature The heat medium channel is communicated with the outside, and the expander and the second expander are connected to the compressor and transmit power to form a third 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 thermal energy to achieve cooling, heating or conversion into power, and also need to use power for cooling or use power and combine Low temperature thermal energy for heating. In the process of realizing the above purpose, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user requirements, ambient temperature, type of working medium, equipment flow, structure and manufacturing costs, etc. [0003] The thermal energy (temperature difference) utilization technology represented by the absorption heat pump technology can simultaneously utilize the temperature difference between the medium-temperature heat load and the cold ...

AI Technical Summary

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.
