Fig. 2 is the principle schematic of evaporative condenser shown in Fig. 1.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, evaporative condenser of the present invention and refrigeration unit are further elaborated.Should be appreciated that specific embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
See figures.1.and.2, the evaporative condenser of one embodiment of the invention, comprises casing 100, spray equipment 400, heat exchanger 500 and oil cooler 600.Wherein, spray equipment 400, heat exchanger 500 and oil cooler 600 are all placed in casing 100, and spray equipment 400 cools respectively for heat exchanger 500 and oil cooler 600.
The bottom of casing 1 is provided with tank 800, and tank 800 is for reclaiming the shower water of spray equipment 400.The lower case of casing 100 is provided with air inlet, the top shell of casing 100 sets out air port.In described air outlet, be also provided with blower fan 200, blower fan 200 is axial flow blower, and blower fan 200 is positioned at the top of heat exchanger 500.Preferably, the quantity of described air outlet is multiple, and multiple described air outlet interval is arranged, all corresponding blower fan 200 of each described air outlet.The air inlet of casing 100 is also provided with air-inlet grille.
As a kind of embodiment, spray equipment 400, heat exchanger 500 and oil cooler 600 set gradually from top to bottom, and namely heat exchanger 500 is placed in the top of oil cooler 600, and spray equipment 400 is placed in above heat exchanger 500.Certainly, spray equipment 400, oil cooler 600 and heat exchanger 500 also can set gradually from top to bottom.Heat transfer effect when but spray equipment 400, heat exchanger 500 and oil cooler 600 set gradually from top to bottom is better.
Wherein, heat exchanger 500 has import 501 and outlet 502, and refrigerant enters heat exchanger 500 from the import 501 of heat exchanger 500, and the outlet 502 from heat exchanger 500 after heat exchange in heat exchanger 500 is flowed out.Heat exchanger 500 is finned heat exchanger or coil exchanger.Oil cooler 600 has oil-in 601 and oil-out 602, and lubricating oil enters oil cooler 600 from oil-in 601, flows out after lubricating oil carries out heat exchange in oil cooler 600 from oil-out 602.Oil cooler 600 can be oily circulation coil pipe.
Relay pump 900 is gone back between spray equipment 400 and tank 800.Water pump 900 for the water in tank 800 is extracted into spray equipment 400, shower water reusable edible like this.
As a kind of embodiment, in casing 100, be also provided with flase floor 700, flase floor 700 is placed between oil cooler 600 and tank 800.Preferably, flase floor 700 is the finned flase floor adopting PVC material to make.The finned flase floor adopting PVC material to make, which increases the heat exchange area of shower water and flase floor 700, improves both heat exchange efficiencies.
As another kind of embodiment, in casing 100, be also provided with water fender 300, water fender 300 is placed between described air outlet and spray equipment 400.Water fender 300 also can adopt dash net to replace.Water fender 300 or dash net are set, prevent the shower water of spray equipment 400 from spilling casing 100 from described air outlet.
The course of work of evaporative condenser as shown in Figure 2, water pump 900 draws water to spray equipment 400 from tank 800, spray equipment 400 is first vaporificly spray on heat exchanger 500 (condenser coil) and oil cooler 600 (oily circulation coil pipe) successively aquation, shower water with heat exchanger 500 heat exchange after be first cooled to 35 degrees centigrade, oil cooling is carried out but again with oil cooler 600 (oily circulation coil pipe) heat exchange, the oil temperature in oil cooler 600 is made to be down to 49 degrees centigrade, after twice heat exchange, shower water becomes high-temperature water, this high-temperature water is scattering into flase floor 700, flase floor 700 carries out heat convection cooling with air, finally fall into tank 800, complete a cool cycles, wherein whole heat transfer process is all carry out in the cross-ventilation auxiliary heat-exchanging produced under blower fan 200 acts on, the air intake of evaporative condenser and air-out are as shown in the direction of arrow in figure.
The invention still further relates to a kind of refrigeration unit, comprise the evaporative condenser of above-mentioned arbitrary technical scheme, because refrigeration unit is prior art except above-mentioned evaporative condenser, repeat no more herein.Refrigeration unit, owing to adopting above-mentioned evaporative condenser, therefore also achieves same Advantageous Effects.
The evaporative condenser of above embodiment and refrigeration unit, evaporative condenser integrated spray device, heat exchanger and oil cooler are in one, directly simplify the system of engineering, eliminate and use the same expensive coefficient oil cooling system of plate type heat exchanger of auxiliary fluid reservoir that frame is high; Project installation no longer needs evaporative condenser to be arranged in higher position, avoids the quantities of the necessary frame height 3-5m of project installation, greatly reduces engineering difficulty and expense; The design that also can be directly used in integrated condensation unit is selected, convenient to freezer engineering, without the need to carrying out the construction of condenser portion.
The water being equal to environment temperature by pump handle temperature is sprayed to condensing heat-exchanging pipe by spray equipment, refrigerant vapours is made to be cooled to liquid, water after participating in condensing heat exchanger heat exchange subsequently pours on oil circuit heat exchange coil again, oil in system is lowered the temperature, final high temperature water is by the finned flase floor of PVC, make water and air carry out heat convection to be cooled, the water in system is recycled by water pump, using water wisely.
In a word, its compact conformation, volume is little, and save raw material, reduce capital construction expense, decrease installing space, improve heat exchange efficiency, reduce energy consumption, energy-saving effect is remarkable.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
