Abstract
The utility model relates to a closed cooling tower used for the refrigerating engineering of the air condition. The interior of the closed cooling tower is provided with a cooling coil and a discharge pipe with a shower nozzle. The cooling water flows in the cooling coil and can not be contacted directly with the air, so the cooling water can keep clean and can be not polluted. Consequently, the defect that a condenser and other devices are influenced by the dirt and the scale in the air is improved, and the closed cooling tower can keep definite work efficiency. The bottom part of the cooling tower is provided with a pond for storing the circulating water, and the circulating water is raised and sent to the discharge pipe by a water pump; through the shower nozzle, the circulating water is sprayed on the outer surface of the cooling coil. The circulating water which is sprayed carries away the partial heat, and therefore, the temperature of the cooling water is reduced. The utility model has the characteristics of low noise, wide purpose, small volume, flexible installation, strong environmental adaptability, etc.
Description
The utility model is a kind of energy-conservation, practical cooling device, can be widely used in air-conditioning refrigeration system, freezer refrigerating system, industrial cooling system, belongs to refrigeration or cooling technology field.
Cooling device of the prior art mostly is the open type cooling tower, as reverse-flow, cross-flow type, spray-type cooling tower, this cooling tower is exposed in the air cooling water to dispel the heat, cooling effectiveness is higher, but because air directly contacts with water in the cooling procedure, cooling water is easily contaminated, thereby, the capital equipment of air conditioner refrigerating---condenser, the easy fouling of absorber and cause its heat transfer coefficient to descend, the refrigerating capacity of refrigeration machine is reduced sharply, in addition, open type cooling tower noise is very big, and cooling water spills more and causes the waste of water.
Goal of the invention of the present utility model is in order fundamentally to solve the problem of condenser fouling, to improve the efficient of refrigeration machine, prolonging the life-span of its critical piece.
The utility model is achieved in that a kind of closed cooling tower of design, adopt the tower body of fiberglass or iron plate material, cooling coil is arranged in tower body, cooling water from refrigeration machine flows in cooling coil, recirculated water enters in the comb that has shower nozzle that is arranged at cooling coil top by water pump, spray is at the outer surface of cooling coil and make cooling water temperature, the recirculated water that temperature is lower (using running water usually) is sprayed on the higher cooling coil surface of temperature, a part absorbs the heat of cooling water and evaporates, a part falls into the pond of tower body inner bottom part, in order to continuing circulation, the water level in the pond is controlled by ball-cock assembly.The tower body bottom is the air inlet that has shutter a little more than the ball-cock assembly place, and blower fan sucks air from air inlet, discharges from the air outlet at top, and water vapour is also discharged with air, is provided with water fender between comb and blower fan, reduces the loss of recirculated water.Cooling coil is made with metal material, in order to improve heat dispersion, mental-finned is arranged outside cooling coil, is the pond of recirculated water in the bottom of cooling tower, makes the water circulation by water pump, adopts ball-cock assembly to control the water level of recirculated water.Into and out of the place, air port, shutter is installed all.
The utility model compared with prior art, major advantage is as follows:
The cleaning that 1, can keep cooling water.Because closed cooling tower does not contact with the external world, therefore, can prevent the pollution of cooling water effectively, cooling water is pure all the time.If cooling water adopts demineralized water, then condenser or process equipment are with regard to non flouling behaviour (comprising incrustation scale and dirt), equipment such as refrigeration machine are worked under high efficiency, save a large amount of cleaning, maintenance cost, lengthen the life of a machine, fundamentally thoroughly solved the difficult problem that lithium bromide refrigerator sharply descends because of the fouling refrigerating capacity.
2, noise is low.In closed cooling tower, cooling water all flows in pipe, has only a spot of recirculated water outside pipe.Therefore, noise is quite low, has the remarkable environmental benefit.
3, purposes is wide.At transition season, when outside air temperature is low,, can be delivered directly to and serves as " chilled water " use in surface cooler, the spray chamber through the water of closed cooling tower cooling, thus the energy consumption that can save refrigeration machine.
4, the adaptive capacity to environment is strong.In the lighter place of air pollution, can use closed cooling tower; In air pollution serious area comparatively, it is preferably to use closed cooling tower.
5, can be used for cooling down high-temperature water.General cooling tower is owing to be subjected to the restriction of carrier performance, and cooling water inlet temperature generally must not be higher than 65 ℃, and closed cooling tower then is not subjected to the restriction of this condition.Therefore, range of application is more extensive.
6, operating cost is low.The cooling water system of using closed cooling tower is a closed system, its cooling water pump lift H=h
1(equipment resistance)+h
2(resistance of ducting); And the open system of application open type cooling tower, its cooling water pump lift H=h
1(equipment resistance)+h
2(resistance of ducting)+h
3(hydrostatic pressure).This shows that use the closed system of closed cooling tower and compare with the open system of using the open type cooling tower, the cooling water pump lift can reduce, operating cost just can reduce.
7, volume is little, and is flexible for installation, easy to use.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.Accompanying drawing is the structural representation of closed cooling tower, among the figure 1---cooling coil, 2---mental-finned, 3---blower fan, 4---water pump, 5---comb, 6---shower nozzle, 7---water fender, 8---the pond, 9---air inlet, 10---air outlet, 11---ball-cock assembly, 12---tower body.
Embodiment is 20 tons/hour a closed cooling tower, high 2.1 meters, long 1.3 meters, wide 1 meter rectangle tower body 12, process and the brushing antirust paint with 1.5 millimeters thick galvanized iron sheets, cooling coil 1 is a copper pipe, guest performer's aluminium matter fin 2, and comb is common iron pipe, imitative sieve watt shower nozzle, at the top is air outlet 10, is blower fan 3 near its underpart, and blower fan is with air inlet 9 inspirations of air from the tower body bottom, together discharge outside the tower together with water vapour, Qi Hua minute water integument does not block the pond 8 that falls into the tower body bottom, and the water level in the pond is by ball-cock assembly 9 controls, and the position of air inlet is a little more than ball-cock assembly.Under 27 ℃ of conditions of air ' s wet bulb temperature, enter 37 ℃ of the cooling water temperatures of cooling tower, leaving water temperature is 32 ℃, has reached temperature drop and be 5 ℃ designing requirement.
