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

The invention provides a fourth-kind heat drive compression-absorption type heat pump, and belongs to the technical field of power, refrigerating and heat pumps. A solution loop is composed of an absorber, a generator, a second generator, a solution pump, a second solution pump, a solution heat exchanger and a second solution heat exchanger. The generator is provided with a refrigerant steam channel communicating with a condenser. The second generator is provided with a refrigerant steam channel communicating with a second condenser. The condenser communicates with the second generator, a throttle valve and an evaporator. The condenser sequentially communicates with a high-temperature heat exchanger, an expander and the absorber through a refrigerant liquid pump. The second condenser communicates with the evaporator through a second refrigerant liquid pump. The evaporator is provided with a refrigerant steam channel communicating with the compressor and the absorber. The generator and the high-temperature heat exchanger are provided with high-temperature heat medium channels communicating with the outer portion, the absorber and the condenser are provided with heated medium channels communicating with the outer portion, the evaporator is provided with a low-temperature heat medium channel communicating with the outer portion, and the second condenser is provided with a cooling medium channel communicating with the outer portion. The expander is connected with the compressor and transmits power, and the fourth-kind heat drive compression-absorption type heat pump is formed.
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...
