Description

A kind of composite construction wet film surface cooler
Technical field
The present invention relates to air-conditioning technical field, particularly relate to a kind of composite construction wet film surface cooler.
Background technology
The type of cooling of existing air conditioner is divided into air-cooled and water-cooled two kinds.
Air-cooled air-conditioning is radiator coil tube by outdoor and blower fan, the heat produced when distributing refrigeration directly to air.Usually radiator coil tube is called surface air cooler (abbreviation surface cooler), its structure is many group copper pipe arrays, and copper Bottomhole pressure has cold-producing medium, rises and connect intensive radiation aluminium fin outside copper pipe.Air-cooled air-conditioning can cooling in summer, winter heating, realize dual-use.During cooling in summer, when surface cooler is for dispelling the heat, be generally called condenser; During winter heating, when surface cooler is for absorbing the heat in air, surface cooler is generally called evaporimeter.Be used for family expenses, small-sized or large-scale source pump.Owing to being drive air by blower fan completely, allowing cold-producing medium in air conditioner at surface cooler appearance and air heat-exchange, make refrigerating efficiency generally only have about COP3.2.
Water-cooling air conditioner then adds cooling water system, air conditioner refrigerant elder generation and cooling water heat exchange, then is dispelled the heat to air by cooling tower.Water-cooling air conditioner mostly generally is single refrigeration air-conditioning unit (screw rod, centrifugal chiller) in large-scale summer.Water cooled air conditioners unit COP is generally more than 5.0, but the volume of water-cooling air conditioner is large, and cost is high, complex structure.
Existing surface cooler structure is made up of ribbed pipe (air conditioner generally adopts copper tube), header and backplate, and rib Bottomhole pressure has cold (heat) cold-producing medium, has fin, closely cooperated by ribbed pipe expand tube and fin outside ribbed pipe.Wherein ribbed pipe and fin are main heat exchanger components.Common fin configuration has around chip, the slot type that wrinkles, rolls chip and nest plate type etc.The heat-transfer area version of surface cooler has board-like (as spiral plate type, shell-and-plate, corrugated plate dst, plate-fin etc.) and tubular type (as shell and tube, bushing type, coiled, fin tube type etc.), what air conditioner was conventional is fin tube type, flat fin, corrugated fin, calking type fin and louvered fin can be divided into, to ensure the perturbation carrying out air heat exchange, under making it be in turbulent condition, improve heat exchange efficiency significantly.
For making air-cooled air-conditioning more energy-conservation, the domestic and international observable index COP improving air-cooled air-conditioning mainly through recovery condensed water or running water spray (mist) two kinds of modes at present.By the condensed water that indoor set during recovery air conditioner refrigerating produces, by condensed water (or running water), on surface cooler, (or near) directly evaporates in different ways, utilize the latent heat that evaporation of water absorbs, the radiating effect of extra enhancing air conditioner watch cooling, reduce the pressure at expulsion of compressor during air conditioner refrigerating, thus reduce the energy consumption of air-conditioning.But the condensed water of air-conditioning is generally all directly drained at present, does not recycle.
Following several mode is mainly contained about the utilization of condensed water in prior art:
(1) ultrasonic atomizer is adopted to be sprinkled upon surface cooler surface by blowing with blower fan after condensate water atomizing.But ultrasonic atomizer very easily damages, cost is high, is difficult to practical.
(2) adopt Miniature centrifugal water pump that condensed water pressurizing atomizing is sprayed at surface cooler surface.But water pump high-speed cruising, in the desultory situation of condensed water, water pump very easily damages, and is difficult to practical.
(3) employing is trickled after condensation water collection in gravity flow mode on surface cooler.But condensed water effective rate of utilization is low, and surface cooler trickles at random, and the problem of dripping does not overcome.
(4) Water submersible evaporator is increased.An additional evaporative condenser, but this mode makes air-conditioning system complicated, and fault rate increases, the reliability of loss air conditioner.
(5) impeller of blower is adopted to throw away condensed water.But this structure condensed water effective rate of utilization is low, be only applicable to wall-through type air conditioner, and in existing domestic air conditioning product, 95% is all separate type air conditioner.
(6) concentrated by condensed water, central water uses.As rinsed pouring etc., but this mode can not play energy-saving effect.
(7) permeable membrane humidifier.Multilayer water lamella, they are surrounded by hydrophobic microporous teflon membran, form one deck tunic bag.Corrugated plating is lined with between water lamella, form air flue, when air flows through between water lamella, the water vapor pressure due to moisture-inhibiting film water side is greater than the partial pressure of water vapor of air side, and water vapour just enters air side from water side by the fenestra of moisture permeable membrane under the effect of its pressure differential.As civilian in perm " utilization of room air conditioner condensed water is with energy-conservation " of table of " HVAC " 2003 the 2nd phase the 33rd.But this mode can increase the wind resistance of air conditioner condensation blower fan, reduce the complete machine coefficient of heat transfer, complex structure and cost is high.
(8) set up a little tank in air-conditioner, first make condensed water be flowed in tank, then utilize Micropump to pump condensed water in atomizer, atomizer sends indoor to the aqueous vapor after atomization, completes the humidification to indoor; Atomizer will be arranged on air delivery duct place, condensation flow to conversion completed by two-way electromagnetic valve." domestic air conditioner without drip can the damping technical research " literary composition delivered as " instrumental technique and sensor " the 10th phase in 2005.But this mode needs a set of numerous and jumbled sensor protection system, and overall cost is high, the cost of domestic air conditioning is made to be difficult to digestion.
(9) adopt the scheme adding micro pump and the combination of hole, 0.5mm × 64 copper pipe trickle, effect is the most obvious, can improve trapped energy theory and reach 8.38%, and refrigerating capacity improves 1.58%, and air-conditioning power reduction reaches 6.29%." small-sized split-type air conditioner utilization of condensed water and energy-conservation experimental exploring and the research " literary composition delivered as " Refrigeration & Air-Conditioning " the 2nd phase in 2006.But this mode cannot reliability service.
In sum, although the Land use systems of existing condensed water is a lot, remain in following defect: or cost is high, or poor reliability, or complex structure, or effective rate of utilization is low.This is also that said method is announced during the last ten years, and commercially available air conditioner does not all arrange the reason of condensation using device.
In addition, the technology directly to surface cooler spray running water is also had, air-conditioner cooling spraying system disclosed in CN201731590U.Its volume increase is comparatively large, and water consumption is large, and need special water pump, cost is high, complex structure, at present also non-large-scale popularization.
Also employing capillary principle strengthens heat radiation, have the condenser of capillary cooling device, but it exists following problem disclosed in CN202281425U:
First, capillary structure is directly arranged in heat dissipation metal fin (wing) sheet surface, large-area, moistening capillary structure directly contacts with air, allows moisture directly in capillary structure surface evaporation, but is arranged on outdoor due to condenser, when blower fan drives a large amount of air to blow to capillary structure surface, dust in outdoor air progressively can be adsorbed on moistening capillary structure surface, very easily blocks heat dissipation channel, not only can not increase radiating effect and also seriously can reduce heat dispersion on the contrary; And be also difficult to wash after the capillary structure absorption fine dust of porous, difficult in maintenance during actual use;
Second, because the surface of metal fin (wing) sheet side is paved with by fibrous capillary structure substantially, if once lack of water in using, the cotton-wadded quilt that just one deck is heat insulation just as metal fin (wing) the sheet upper cover at high temperature, this can reduce the radiating effect of original fin (wing) sheet equally greatly, can damage compressor of air conditioner time serious;
3rd, its capillary water absorption layer and tank are located at the below of heat radiating fin (wing) sheet, water in tank will upwards permeate under capillary forces, certainly will be affected by gravity, moisture is difficult to the upper end reaching capillary structure at short notice, so have to set up the parts such as water pipe, magnetic valve of prewetting, make complex structure, functional reliability reduces; Meanwhile, the dirt formed after the water suction of outdoor dust can along the tank of capillary water absorption laminar flow to below, need not how long, and dirt will fill up tank, makes whole capillary water absorption thrashing;
4th, because capillary structure is directly arranged in metal fin (wing) sheet surface, and capillary structure is loose fibre structure, different from the physical property of metal fin (wing) sheet, the intensity that the two contact coordinates will by outdoor long-term high temperature, high humidity, vibrations, wind, the test particularly during high pressure water cleaning, large-area capillary fiber is easily damaged, easy and metal fin (wing) sheet is peeled off, and occur fit clearance, service life and radiating effect all can reduce;
5th, only consider how to control output in this Patent design, do not consider the calcium ions and magnesium ions problem in water, although the radiating effect of condenser can be strengthened at short notice, if but run time several months, condenser fin (wing) sheet of high temperature will make the calcium ions and magnesium ions in water form incrustation scale hard in a large number on capillary structure surface, causes radiating effect to reduce gradually, and extremely difficult cleaning; Meanwhile, be control the output of running water, it devises the control system of a set of complexity, and as being provided with water level sensor in tank, water inlet pipe has the water check valve, magnetic valve etc. that control the water yield, causes functional reliability to reduce;
6th, although, it can strengthen the radiating effect of air-conditioning unit room external condenser when summer air-conditioning freezes, but from the refrigeration of air conditioner, heat principle can know, be positioned at the condenser of outdoor high temperature heat radiation summer when having arrived winter heating, become the evaporimeter that low temperature absorbs heat, steam in air can condense out a large amount of condensed waters on metal fin (wing) sheet of low temperature, so the fin of conventional air-conditioning (wing) sheet all makes smooth surface, be beneficial to condensed water dirty rapidly, and now, if arrange large area capillary fiber structure on smooth fin (wing) sheet, the speed that condensed water leaves metal fin (wing) sheet can be reduced on the one hand, on the other hand, the capillary structure being filled condensed water seriously can hinder the heat transfer of air and metal fin (wing) sheet, cause condensed water quick freezing, progressively between fin (wing) sheet, form large area freezing, the flowing of blocking air, form vicious circle, air-conditioning cannot normally be run at all, and now also capillary structure can not be removed from fin (wing) sheet, its practicality is not as good as the patent of direct spray fin above, and it is basic that this point is that this patent cannot be practical.
Summary of the invention
Technical problem to be solved by this invention is: the above-mentioned deficiency overcoming prior art, for air conditioner provides a kind of energy-conservation, cost is low, unpowered, reliability is high, structure simple composite construction wet film surface cooler, air conditioner condensate water can be reclaimed completely, radiating efficiency and the Energy Efficiency Ratio of air conditioner watch cooling can be improved, reduce pressure at expulsion during air conditioner refrigeration, and frost-free when air conditioner watch cooling is heated in the winter time.

operation principle of the present invention:
Based on the bionic principle of moisture movement in natural plant body, on the dry air heat radiation basis that common surface cooler is simple, pass through the present invention, dexterously wet film layer and fin are merged, increase water and directly evaporate link on surface cooler, not only make use of the sensible heat transfer during air flowing when air conditioner is dispelled the heat, also make full use of the latent heat treatment of water evaporative phase-change (fluid-gas).The present invention specifically utilizes the rising power of moisture constantly evaporation generation after surface cooler heating in fiber capillary force and wet film layer, be similar to the motion principle of moisture in plant, allow water nature, evenly, fast infiltrate to the whole surface of each fin, do not need any power; Offer some calkings, punching or shutter at fin surface simultaneously, moisture in wet film layer can be allowed constantly to evaporate, be similar to and have numerous trickle cooling tower at fin surface, thus reach the radiating effect close with adopting cooling tower+water-cooling air conditioner and Energy Efficiency Ratio.
Preferred version of the present invention: water suction wet film layer is closely pressed in centre by the metal fin of adjacent two, form " sandwich " structure of compound, moisture in wet film is some calkings by metal fin is opened, punching or shutter evaporation, wet film is not directly and air bump contact, the dust of air is avoided directly to be adsorbed on moistening moisture membrane surface, blocking fin, affect radiating effect, even if having a small amount of dust adsorption on fin, but its smooth metal surface is also beneficial to dust granule to come off, clean and maintenance of being more convenient for.And being closely pressed in the middle of two metal fins due to wet film layer, its service life is also almost the same with fin, and when being also able to stand cleaning, water washes away.
In addition, the compounded wet film unit of each " sandwich " structure, its heat exchange area is still equal to two radiating surfaces of piece of metal fin, can accomplish like this to make the area of dissipation of compounded wet film surface cooler still identical with the area of dissipation of former conventional surface cooler.So, even if compounded wet film lack of water, surface cooler still can utilize fin outer surface and air directly to dispel the heat, and does not rely on wet film layer, air conditioner is normally run, without any risk.
Water sucting belt is arranged at the side of wet film layer by preferred version of the present invention: under the effect of capillary principle, the flow direction of moisture in wet film, divide two-way naturally osmotic up and down, by adjusting the relative altitude of catch basin and wet film layer, can allow moisture rapidly, to the upper and lower position of wet film layer, (height upwards permeated can reach the top of wet film layer to uniformly penetrating, and just in time can balance with Action of Gravity Field, during downward infiltration, gravity can accelerate the infiltration of water on the contrary), do not need other auxiliary (water pipe of prewetting) device completely; In addition, when reality uses, the dust on fin, or muddy water during cleaning down can come off naturally along fin, flows away, can not enter side catch basin.
In addition, in the system that the present invention simplifies, condensed water directly can also be allowed through the dripping device at wet film top, evenly drip on wet film, make structure simpler.
Innovation of the present invention is also: compounded wet film surface cooler does the condenser use of dispelling the heat at cooling in summer, can make the evaporimeter absorbed heat and use during winter heating.Not only can strengthen the heat sinking function of condenser in summer; And can also in the winter time air-conditioning heating time, by adding anti-icing fluid storing in (confession) tank, stoping fin frosting, strengthening heating effect in winter, fin frosting when solving current air-conditioning winter heating, the common fault that heating efficiency is low.
Another large feature of the present invention is, owing to adopting " sandwich " structure, during winter heating, air condensed water, in the metal fin surface condensation of " sandwich " composite construction both sides, directly falls, and not easily contacts with the anti-icing fluid in wet film.When for large-scale air source heat pump air-conditioner unit, the heat source tower (as closed type heat source tower) adopting anti-icing fluid to mix completely with air relative to other or the air-conditioning system of energy tower, the quantity of anti-icing fluid can be greatly reduced, save operating cost, and make air-conditioning system simpler.
And owing to adopting " sandwich " structure, its appearance is completely the same with conventional surface cooler, is all smooth surface, does not affect the heat exchange of outdoor air and fin at all, and the eliminating of condensed water, and heat exchange area also can be accomplished to be equal to conventional surface cooler completely.Even if therefore heat in the winter time and do not use anti-icing fluid, also can normally run.
Finally, wet film and the water needed for tank in the present invention, the condensed water that when mainly taking from refrigeration, evaporimeter produces, makes air conditioner not only power saving but also water-saving like this; And condensed water not calcic, magnesium mineral matter, can not at fin surface scaling; On the other hand, operation of air conditioner is only had just to have condensed water, the air conditioner condensation water yield has corresponding relation with the heat dissipation capacity of air-conditioning again, can ensure that condensed water is evaporated completely by suitable coupling, excessive water is there will not be to outflow, so do not have in system also to arrange complicated water level, water flow control system, very succinctly.From the discharge angle of condensed water, or a kind of air-conditioning of evaporated condensation water, remove the outer discharge pipe of condensed water from and install, installing and using of more convenient air-conditioning.
In a word, the present invention not only can strengthen the heat radiation of air-conditioning in summer, energy-conservation more than 20%, and can solve winter air-conditioning frosting problem, improves heating effect, and structure is simple, safe and reliable, accomplishes real environmental protection, water saving, energy-conservation; Meanwhile, no matter be cooling in summer or winter heating, even if the wet film layer in surface cooler does not come into operation, also can ensure that air-conditioning normally runs.
