Description

Injection evaporative cooling air-cooled heat pump module unit

Technical Field

The invention relates to the field of heat exchangers, in particular to an injection evaporative cooling air-cooled heat pump module unit.

Background

The existing evaporation cold and heat pump unit takes water as a cooling medium for refrigeration, and can make a refrigerant obtain lower condensation temperature than water cooling, particularly an air cooling mode by utilizing the latent heat of the water and a sensible heat exchange mode, so that the evaporation cold and heat pump unit has higher refrigeration efficiency; when heating, air is used as a heat source, so that the problem that a water cooling unit, including an evaporation cooling unit, is low in heating efficiency or cannot heat at all is solved.

However, the existing evaporation cold heat pump unit has the disadvantages that the volume of the existing unit is large, the number of internal parts of the unit is large, the pipeline design is complex, the manufacturing cost of the equipment is high, and the popularization of the unit is not facilitated due to the fact that the cold source heat exchanger, namely the evaporation cold heat exchanger, and the heat source heat exchanger, namely the air source heat exchanger, are integrated.

Specifically, the existing evaporation cold and hot pump unit has the following defects:

the volume is bigger: because the cooling water sprays from the spray (water distributor) and flows through the evaporative condensation heat exchanger in turn along with the cooling water in the cooling water and refrigerant heat exchange temperature rise process and the cooling water and air heat exchange temperature drop process, the stroke of the packing layer dropping into the cooling water tank is too long, so that the longitudinal height of the evaporative heat pump unit is increased, the unit volume is increased, and the corresponding unit manufacturing cost is increased. In order to ensure uniform water distribution on the surface of the evaporative cooling heat exchanger, enough clearance is required to be left between the sprayer and the evaporator; in order to fully cool the cooling water after heat exchange with the refrigerant, the cooling water dropped from the evaporative cooling heat exchanger and the water surface of the cooling water tank should keep a quite long distance, so that a large amount of cooling water can be taken away by a fan when the unit works, water splashing and water floating phenomena are formed, the waste of the cooling water is caused, the cooling water is attached to the surface of a unit component to cause the corrosion of the unit, and the service life of the unit is shortened.

The heating attenuation is serious: the evaporative cooling is the most efficient cooling method, so that the unit has higher cooling efficiency, but the heating capacity in the air-cooled heat pump mode is attenuated along with the reduction of the outdoor environment temperature, so the heating efficiency under the low-temperature working condition needs to be improved.

Based on the technical limitation of evaporation cold and hot pump unit, the application provides an injection evaporation cooling air-cooled heat pump module unit.
