Description
Technical field
Condensing unit is cooled down the present invention relates to one kind, is mainly used in fluid medium and is cooled.
Technical background
The existing apparatus for being cooled down or being condensed for fluid medium generally comprises water cooling heat exchanger, air cooling heat exchanger
And evaporating heat exchanger.Wherein water cooling heat exchanger is sensible heat transfer mode, it is necessary to substantial amounts of water is as cooling medium, this cooling side
Formula water consumption and power consumption are big, especially the area in water shortage, it is difficult to realize；Air cooling heat exchanger has in the case where ambient air temperature is relatively low
There is unique advantage, although do not need water consumption, but consuming electric power is big, and noise is larger, particularly in the higher situation of environment temperature
Under, limited often by space and have the shortcomings that heat exchange efficiency is low；Evaporating heat exchanger is latent heat heat exchange form, with preferably changing
The thermal efficiency and power consumption is less, it is particularly with the obvious advantage when ambient air temperature is higher, but product its master in the market
Have the disadvantage that heat transfer capacity is relatively low, and water consumption is larger.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of evaporating air-cooling double-effect heat exchange device, reach and significantly economize on water
With the purpose of economize on electricity.
To reach above-mentioned purpose, present invention employs following technical scheme.
Water vessel is installed in evaporating air-cooling double-effect heat exchange device, including housing, housing, it is characterised in that：Water vessel will
Space is divided into precooling chamber and main cold chamber in housing；Wherein the housing of precooling chamber is provided with circulating fan, and precooling intracavitary is provided with pre-
Cold heat exchanger；The housing of main cold chamber is provided with air inlet, and main cold intracavitary to main cold heat exchanger provided with main cold heat exchanger and for spraying
Drench evaporation fluid injector；Precool heat exchanger device and main cold heat exchanger are interconnected by connecting tube, and precool heat exchanger device carries medium flow field
Enter pipe, main cold heat exchanger carries medium effuser.
Also include water circulating pump and the water leg below main cold heat exchanger, water circulating pump respectively with the water leg
It is connected with the nozzle.
The invention has the characteristics that.
The advantage of present invention collection vaporation-type and cooling type heat exchange device, is ensureing that heat transfer effect reaches evaporating heat exchanger water
On the premise of flat, evaporation amount of liquid is significantly saved, and substantially reduce system energy consumption.Specifically it is discussed below：
Implement fluid media (medium) cooling, condensation, spraying and sprinkling evaporation liquid using the device of the present invention（Such as shower water）Gas after evaporation
Liquid mixture first passes around water vessel and catches water, and the globule is blocked in into main cold intracavitary, changed into the humid air in precooling chamber and precooling
The fluid media (medium) that is cooled in hot device carries out heat exchange, so that temperature of fluid medium is reduced, while humid air temperature is raised, and
Humid air is discharged outside precooling chamber by the effect of circulating fan.Under normal circumstances, evaporative condenser is in condensation temperature identical
In the case of, discharge humid air temperature is higher, illustrates that condenser water consumption is lower, heat transfer effect is better.Cooled fluid media (medium) exists
Precooling intracavitary is first cooled down, and is correspondingly just reduced the injection flow rate of main cold intracavitary shower water and is reduced flux matched with water spray
Circulating fan load, so as to reach the purpose of water-saving and electricity-saving.On the other hand, at low ambient temperatures, may be used
To stop water spray, air-cooled cooling is directly used, so as to reach the purpose of significantly water-saving and electricity-saving.
In addition, vaporation-type heat exchange is integrated in same housing by the present invention with cooling type heat exchange, a set of circulated air system is utilized
System, so that structure of the present invention is compacter, not only reduces manufacturing cost, has saved floor space, and improve spray
The service efficiency of water and circulated air.
Brief description of the drawings
Fig. 1 is the structure and operation principle schematic diagram of the present invention.
