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 absorber, generator, solution pump and solution heat exchanger form a solution circulation system. The generator has a refrigerant vapor channel connected to the compressor, and the compressor has a refrigerant vapor channel connected to the condenser. The condenser is connected to the evaporator through a throttle valve. The condenser is connected to the high-temperature heat exchanger through the refrigerant liquid pump. The high-temperature heat exchanger has a refrigerant vapor channel connected to the expander. The expander has a refrigerant vapor channel connected to the second condenser. The second condenser is connected to the second refrigerant liquid pump. Connected to the evaporator, the evaporator has a refrigerant steam channel connected to the absorber, the generator and high-temperature heat exchanger have a high-temperature heat medium channel, the absorber and condenser have a heated medium channel, the evaporator has a low-temperature heat medium channel, and the second condensation The cooling medium channel of the device communicates with the outside respectively, and the expander connects with the compressor and transmits power, forming the first 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...

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

Compression heat pump technology has good flexibility in terms of thermodynamic performance, but the core components of compression heat pumps are moving parts, which brings many disadvantages - for example, the noise generated during the operation of compression heat pumps is unbearable; for this reason , need to consider reducing the use and number of large moving parts (mainly compressors and expanders)
