Description
Technical field
The utility model relates to a kind of cascade evaporative condenser.
Background technology
Existing cooling method generally has following three kinds:
One of which, cascade air-conditioning temperature-reducing mode:
Cool principle: the temperature-fall period of negative pressure cooling system is in its core--accomplishes in-wet curtain the paper.At undulatory fiber surface the thin moisture film of layer arranged; When outdoor dry air was passed wet curtain paper by blower fan suction, the water in the moisture film evaporated after can absorbing airborne heat, takes away a large amount of latent heat; Air themperature through wet curtain paper is reduced; Through being in the nice and cool wet air inlet chamber after handling like this, after indoor hot-air mixes, through the outdoor cooling-down effect of realizing of blower fan discharge.
Shortcoming: narrow between cooling area during use, the sky temperature is reduced to about the 27--30 degree, only be applicable to field of air conditioning and be less demanding place; The cooling of cascade air-conditioning has strengthened air humidity (generally 85%) simultaneously in addition, has limited its scope of application.
Two, air-cooled condenser cooling method:
Cool principle: constantly blow to the air that is lower than condenser temperature on the condenser through blower fan, make air siphon away the high temperature on the condensing gas, reduce condenser temperature; Until the temperature close with environment temperature.
Shortcoming: condensation efficiency receives outdoor temperature restriction bigger, and when condenser service time was longer, the surface had more dust, produces mouldy thing sometimes and reduces condenser condenses efficient.
Three, evaporative condenser cooling method:
Cool principle: shower water is transported to the water in the water leg by water pump the shower at evaporative condenser top; The outer surface that sprays the condensation comb through nozzle forms very thin moisture film; Be evaporated to steam after the heat absorption of part water in the moisture film, all the other fall into water leg, and supply-water pump recycles.The axial flow blower forced air is inhaled into the coil pipe of flowing through from top and lower sidewall; Filler, saturated hot humid air then are discharged in the ambient atmosphere; The part water droplet of carrying secretly in the hot humid air is held back through water collection device; Control water droplet effectively and fly away loss, the lost vapor in the atmosphere that causes replenishes cooling water by ball-cock assembly control in system.
Shortcoming: high-intensity evaporation, make evaporative condenser more be prone to scaling than other type condenser, also there is not desirable descaling method at present; The evaporative condenser of serious fouling has just lost the advantage of economize on electricity.
Summary of the invention
The technical problem that the utility model will solve is: in the existing cooling structure, the cooling method efficient that fault rate is low is low, the scope of application is little; What cooling efficient was high receives external environment influence, fault rate high easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the cascade evaporative condenser comprises housing, housing built-in cascade unit and condensing unit; Said cascade unit comprises spray water-feed, cascade paper, and said spray water-feed is communicated with outside pressure water source; Said condensing unit comprises condenser and blower fan; Aforementioned cascade paper, condenser, blower fan are provided with in the past backward in order.
When the refrigerating function key is opened, spray water on the cascade of drying by the spray water-feed, make it to become wet; Start blower fan, suck the lower air of humidity, and make it in order through cascade paper and condenser; Cascade paper can make the inhaled air temperature reduce the 7-15 degree through water evaporative cooling mode, like this, when air stream process condenser, just can make condenser temperature also reduce the 7-15 degree simultaneously; According to refrigeration principle, just practiced thrift the cooling power consumption of 7-15 degree, bigger raising condenser condenses efficient.
Be using water wisely, improve the control accuracy of discharge, said cascade unit also is provided with header tank, water pump; The water intake end of said header tank is communicated with outside pressure water source; Water pump is positioned at header tank, and it is communicated with the spray water-feed, and the water in the header tank is squeezed in the spray water-feed.Control through external control system; In header tank, squeeze into certain water consumption earlier, through water pump water is squeezed in the spray water-feed as required again, can accurately control the size of water spray; The water yield hour can be used for making cascade paper to keep moistening, can be used for washing away cascade paper when the water yield is big.
Be the stability of the condensation efficiency that keeps condenser surface, said cascade unit also is provided with the dust removal and filtration net, and said dust removal and filtration net is set in parallel in the front end of cascade paper.The setting of dust removal and filtration net can be removed the dust impurity that exists in the air; Make through the water vapour behind the cascade paper comparatively clean; And can not produce incrustation scale when not having the Metal Contact of water vapour and condenser of dissolved matter, help keeping the stability of the condensation efficiency of condenser surface.
For ease of the control maintenance, said cascade unit also is provided with blowdown magnetic valve and water supply electromagnetic valve, and said water supply electromagnetic valve is on the pipeline between header tank and the outside pressure water source, and the blowdown magnetic valve is through the bottom of pipeline connected set water tank.Through the control water supply electromagnetic valve, what of the header tank water yield are scalable get into; After cascade paper service time was long, the more dirt that can condense on the cascade paper can be removed it through the current flushing; In addition; Long service time when header tank, can at the bottom of case, produce incrustation scale, clean the sewage of header tank generation and then can discharge housing through the blowdown magnetic valve.
The utility model has the advantages that: the cascade evaporative condenser is compared with the cascade air-conditioning, and it is low to have inherited its cooling power consumption, and characteristic of simple structure and dust removing effects preferably overcome the shortcoming of its narrow in application range; The cascade evaporative condenser is compared with air-cooled condenser, on its basis, outdoor temperature has been reduced the 7--15 degree, bigger raising condenser condenses efficient; Dust removing effects is preferably arranged simultaneously, make condenser surface keep condensation efficiency preferably; Comprehensive saving is about more than 30%; The cascade evaporative condenser is compared with the vaporation-type condenser, has inherited its characteristics of energy saving and the characteristics of effectively practicing thrift the condenser heat exchange area; Overcome its fouling shortcoming; Existing all condensers of the system of can replacing, production cost are lower, simple in structure, ready-made technical basis is arranged in productions, and only a need simple refit gets final product, and helps large-scale production and popularization.
