First-class thermal driving compression-absorption heat pump

Abstract

The invention provides a first-class thermal driving compression-absorption heat pump, and belongs to the technical field of power, refrigeration and heat pumps. An absorber, a generator, a solution pump and a solution heat exchanger form a solution circulating loop; the generator has a refrigerant steam channel to communicate with a condenser; the condenser is communicated with an evaporator by a throttle valve; the condenser is communicated with a high-temperature heat exchanger by a refrigerant liquid pump; the high-temperature heat exchanger has a refrigerant steam channel to communicate with an expander and the absorber in sequence; the evaporator has a refrigerant steam channel to communicate with a compressor and the absorber in sequence; the generator and the high-temperature heat exchanger have high-temperature heat medium channels; the absorber and the condenser have heated medium channels; the evaporator has a low-temperature heat medium channel to communicate with the external; and the expander is connected with the compressor for transmitting power to form the first-class thermal driving compression-absorption 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 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, we will face many constraints - the type, grade and quantity of energy, the type, grade and quantity of user needs, the type of working medium, the process, structure and manufacturing cost of equipment, and the operation of equipment. safety, ambient temperature and environmental acceptability, etc. [0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology uses high-temperature heat load to drive to realize heating or cooling; af...

Problems solved by technology

[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology uses high-temperature heat load to drive to realize heating or cooling; affected by the nature of the working medium (solution and refrigerant medium), the high-temperature heat load at too high temperature or too low The low-temperature heat load of temperature is often not reasonably applied to the absorption heat pump process, resulting in a relatively limited application field and application range
