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

The generator, the second generator, the absorber, the solution pump, the solution heat exchanger and the second solution heat exchanger form a solution circuit, the generator has a refrigerant steam channel connected to the condenser, and the second generator has a refrigerant steam channel and The second condenser is connected, the second condenser is connected with the generator, the throttle valve and the evaporator, the second condenser is connected with the high-temperature heat exchanger, the expander and the absorber in sequence through the second refrigerant liquid pump, and the condenser is passed through the refrigerant The liquid pump is connected to the evaporator, and the evaporator has a refrigerant vapor channel connected to the absorber through the compressor, the generator and the high-temperature heat exchanger have a high-temperature heat medium channel, the absorber and the second condenser have a heated medium channel, and the evaporator has a low-temperature The heat medium channel and the condenser have a cooling medium channel to communicate with the outside, and the expander is connected to the compressor and transmits power to form a fourth type of heat-driven 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...
