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

Embodiment Construction
[0036] The first thing to explain is that in the expression of the structure and process, it will not be repeated if it is not necessary; the obvious process will not be expressed. The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0037] figure 1 The fourth type of thermally driven compression-absorption heat pump shown is realized as follows:
[0038] (1) Structurally, it mainly consists of absorber, second absorber, generator, second generator, condenser, evaporator, throttle valve, solution pump, second solution pump, solution heat exchanger, second Composed of solution heat exchanger, refrigerant liquid pump, high-temperature heat exchanger, expander and compressor; absorber 1 has a dilute solution pipeline that communicates with the second absorber 2 through the solution heat exchanger 10, and the second absorber 2 Also have dilute solution pipeline to be communicated with generator 3 through solution p...

The invention provides a fourth type of heat-driven compression-absorption heat pump, which belongs to the technical field of power, refrigeration and heat pumps. The absorber, the second absorber, the generator, the second generator, the solution pump, the second solution pump, the solution heat exchanger and the second solution heat exchanger form a solution circulation loop, and the generator has a refrigerant steam channel connected in turn to compress The condenser is connected to the second generator, the throttle valve and the evaporator through the refrigerant liquid pipeline, and the condenser is connected to the high-temperature heat exchanger, the expander and the evaporator in sequence through the refrigerant liquid pump, and the evaporator has a cooling The agent steam channel is connected to the absorber, the generator and the high-temperature heat exchanger have a high-temperature heat medium channel, the absorber and the condenser have a heated medium channel, the evaporator has a low-temperature heat medium channel, and the second absorber has a cooling medium channel to communicate with the outside , the expander is connected to the compressor and transmits power, forming the 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...
