Abstract

The invention discloses an ejecting evaporative cooling type air-cooled heat pump unit. The unit comprises a refrigerant pump push module, a rectification module, a cold and heat source heat exchanger module, an ejection module and a use side module. According to the unit, an evaporation-cooled refrigeration main machine and a cooling tower are highly integrated, an air-cooled heat exchanger is additionally arranged in an evaporation-cooled unit by taking an air-cooled heat pump module unit as a template, and a brand new machine type, specifically, an air-cooled and evaporation-cooling integrated multi-source cold and hot water module unit integrating the air-cooled heat pump unit and a water-cooled unit, is created. According to the unit, small modularization of a traditional water cooling unit is achieved, meanwhile, the heating function of an air-cooled heat pump of an evaporation cooling unit is expanded, meanwhile, the mechanical efficiency of the heat pump is greatly improved through the air injection ejection technology, and miniaturization of a large unit, integration of freezing and cooling, integration of air cooling and evaporation cooling, diversification of cold sources and heat sources, high efficiency of refrigeration and heating and convenience in installation, operation and maintenance can be achieved.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to an ejection evaporative cooling type air-cooled heat pump unit. Background technique [0002] The existing evaporative cooling and heat pump units use water as the cooling medium for refrigeration, and the use of latent heat of water plus sensible heat exchange can make the refrigerant obtain a lower condensation temperature than water cooling, especially air cooling, so it has higher cooling efficiency; When it is hot, air is used as the heat source, which avoids the problem of low heating efficiency or no heating at all for water-cooled units, including evaporative cooling units. [0003] However, because the existing evaporative cooling and heat pump units are co-operated with the cold source heat exchanger (ie, the evaporative cooling heat exchanger) and the heat source heat exchanger (ie, the air-cooled heat exchanger), not only the size of the existing unit is large, but also...
