The first type of thermally driven compression-absorption heat pump

Abstract

The invention provides the first type of heat-driven compression-absorption heat pump, which belongs to the technical field of power, refrigeration and heat pump. The condenser is connected to the evaporator through the throttle valve, the evaporator has a refrigerant steam channel to communicate with the compressor, the compressor has a refrigerant steam channel to communicate with the expander through a high-temperature heat exchanger, and the expander has a refrigerant steam channel to the generator The generator communicates with the condenser through the second throttle valve, and the generator communicates with the condenser through the refrigerant steam channel; the evaporator communicates with the absorber through the refrigerant steam channel, and the absorber communicates with the condenser through the solution pump and the solution heat exchanger. The generator is connected, and the generator is connected to the absorber through the solution heat exchanger; the high-temperature heat exchanger has a high-temperature heat medium channel to communicate with the outside, the absorber and condenser have a heated medium channel to communicate with the outside, and the evaporator has a low-temperature heat medium channel Communicating with the outside, the expander connects the compressor and transmits power, forming a heat-driven compression-absorption heat pump of the first type.

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, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user needs, ambient temperature, type of working medium, equipment flow, structure and Manufacturing costs and more.

AI Technical Summary

Problems solved by technology

[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology uses high-temperature heat load to drive heat supply or cooling; affected by the nature of the working medium (solution and refrigerant medium), high-temperature heat load cannot be reasonably applied to absorption In the heat pump process, its application field and application range are greatly limited; it is also unable to take advantage of the large latent heat of refrigerant vapor in absorption heat pump technology

[0004] Compression heat pump technology, which utilizes the grade difference between mechanical energy and thermal energy, has certain flexibility; but in many cases, it is difficult for such compression heat pumps to achieve reasonable utilization of thermal energy

At the same time, the two heat pump technologies also have a common deficiency - they cannot convert thermal energy into mechanical energy while heating or cooling
