The second type of thermally driven compression heat pump

Abstract

The invention provides a second type of heat-driven compression heat pump, which belongs to the technical field of power, heat supply and heat pump. The compressor has a circulating working medium channel that communicates with the heater, the heater also 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 expander, and the expander also has a circulating process The refrigerant passage communicates with the condenser, the condenser also communicates with the circulating refrigerant passage with the compressor, the condenser and the circulating refrigerant passage communicate with the evaporator through the booster pump, and the heater and the heated medium passage communicate with the outside. The evaporator also has a heat source medium channel to communicate with the outside, the condenser also has a cooling medium channel to communicate with the outside, and the expander is connected to the compressor and transmits power to form a second 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] 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.
