Type V thermally driven compression-absorption heat pump

Abstract

The invention provides a type V thermally driven compression-absorption heat pump, and belongs to the technical fields of power, refrigeration and heat pumps. A solution loop consists of a generator, a second generator, a third generator, an absorber, a second absorber, a solution pump, a second solution pump, a third solution pump, a solution heat exchanger, a second solution heat exchanger and a third solution heat exchanger, wherein the generator communicates with a condenser; the second generator communicates with a second condenser; the third generator communicates with the absorber; the condenser communicates with an evaporator through a refrigerant pump and the absorber; the second condenser communicates with the evaporator through the third generator; the second condenser sequentially communicates with a steam generator, an expander and the evaporator through a second refrigerant pump; a low-temperature heat medium channel formed outside communicates with a compressor, the evaporator and a second expander; the evaporator communicates with the second absorber; and medium channels communicating with the outside are respectively formed in the generator, the second generator, the second absorber, the condenser, the second condenser and the steam generator.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of power, refrigeration and heat pump. [0003] Background technique: [0004] 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. [0005] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology uses high-temperature heat load to drive to realize heating...

AI Technical Summary

Problems solved by technology

[0005] 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
