Abstract

The invention discloses an ejecting evaporative cooling air-cooled heat pump module unit. The ejecting evaporative cooling air-cooled heat pump module unit comprises a refrigerant pump pushing module, a rectifying module, a cold and heat source heat exchanger module, an ejecting module and a use side module. According to the ejecting evaporative cooling air-cooled heat pump module unit, an ejecting technology is adopted, on the premise that the power of a compressor is not increased, kinetic energy in the refrigerant circulation process is recycled, the refrigerating and heating COP of the unit can be effectively improved, and the unit is more energy-saving; the design of single-way and double-way full-coverage bridge type connecting pipelines of an air source heat exchanger and an evaporative cooling heat exchanger is adopted, different series and parallel connection modes can be changed for combined use under different working conditions, so that the two heat exchangers can be independently used and can also be mutually supplemented, the economical efficiency of an evaporative cooling heat pump unit is improved, and popularization is facilitated; and miniaturization of a large-scale unit, integration of freezing and cooling, integration of air cooling and water cooling, diversification of cold sources and heat sources, high efficiency of refrigerating and heating and convenience of installation, operation and maintenance can be realized.

Description

Technical field [0001] The present invention relates to the field of heat exchanger, and more particularly to an introduction of evaporation cooling air cooling heat pump module unit. Background technique [0002] The existing evaporative cold heat pump unit is refrigerated with water to cool the medium, and the heat transfer method of water uses water can make the refrigerant to obtain cold-cooled temperature, especially the cooling temperature, and therefore has higher refrigeration efficiency; Take the air as a heat source, avoid the heat-cooling unit including the evaporation of the cold unit, which is low or not heating. [0003] However, the existing evaporative cold heat pump unit due to the cold source heat exchange, the evaporation of the cooling heat exchanger and the heat source heat exchanger, the air source heat transfer, which not only causes the existing unit to be large, and there are many components in the unit. The road design is complex, leading to high equipme...
