Duplex combined cycle compression heat pump

Abstract

The invention provides a dual-mass combined cycle compression heat pump, which belongs to the technical field of energy, power and heat pumps. The heat supplier has a condensate pipeline connected to the mixed evaporator through the circulating pump, the expander has a steam channel connected to the mixed evaporator, the mixed evaporator has steam channels connected to the compressor and the second expander, and the compressor has a steam channel through the high-temperature heat The exchanger is connected to the expander, and the second expander has a steam channel connected to the heater; the second compressor has a circulating medium channel connected to the second heater, and the second heater has a circulating medium channel connected to the evaporator through a throttle valve. The evaporator has a circulating medium channel connected to the second compressor; the high-temperature heat exchanger and the mixed evaporator have a heat source medium channel, the heater and the second heater have a heated medium channel, and the evaporator has a low-temperature heat medium channel to communicate with the outside respectively. In communication, the expander and the second expander connect the compressor and the second compressor and transmit power to form a dual-mass combined cycle compression heat pump.

Description

Technical field: [0001] The invention belongs to the field of energy power and heat pump technology. 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.
