First-class thermally-driven combined cycle heat pump device

Abstract

The invention provides a first-class thermally-driven combined cycle heat pump device, and belongs to the technical field of refrigeration and heat pumps. The compressor communicates with the high-temperature heat exchanger through a circulating working medium channel, the high-temperature heat exchanger communicates with the expansion machine through the circulating working medium channel, and the expansion machine communicates with the heat supply device through the circulating working medium channel and then is divided into two paths. After the second path is directly communicated with the heat regenerator, the heat regenerator is communicated with the evaporator through a condensate pipeline via a throttle valve, the evaporator is communicated with the heat regenerator through a circulating working medium channel via a second compressor, and the heat regenerator is communicated with the compressor through a circulating working medium channel; the high-temperature heat exchanger further communicates with the outside through a high-temperature heat medium channel, the heat supplier further communicates with the outside through a heated medium channel, the evaporator further communicates with the outside through a low-temperature heat medium channel, the expansion machine and the second expansion machine are connected with the compressor and the second compressor and transmit power, and the first-class thermally-driven combined cycle heat pump device is formed.

Description

Technical field: [0001] The invention belongs to the technical field of refrigeration and heat pumps. 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, many constraints and restrictions are often faced-for example, 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, etc. From the perspective of the heat source, the heat source medium and the heated medium often have the characteristics of variable temperature and high temperature at the same time, which makes the performance index unreasonable, the heating parameter is ...

Problems solved by technology

In the process of achieving the above goals, many constraints and restrictions are often faced-for example, 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 cost, etc.

From the perspective of the heat source, the heat source medium and the heated medium often have the characteristics of variable temperature and high temperature at the same time, which makes the performance index unreasonable, the heating parameter is not high, and the compression ratio often exists when cooling or heating is realized based on a simple thermodynamic cycle. Many problems such as being too big and working under pressure
