The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, the direct Evaporative Cooling Air Conditioning unit of the little mist combined type of filler-high pressure of the present utility model adopts water and hot device for heat/moist exchange of filler direct contact type and the compound structure of the hot device for heat/moist exchange of the little mist of high pressure, has utilized the direct evaporative cooling of two-stage.On the relative sidewall of machine unit shell, be respectively arranged with air inlet 1 and air outlet 15, in the machine unit shell, be disposed with roughing efficiency air filter 2, filler 6, water fender 13 and pressure fan 14 by the air intake direction, the bottom of filler 6 is provided with cistern a7, the front portion of filler 6 and top are furnished with feed pipe a3 and feed pipe b4 respectively, are evenly equipped with a plurality of nozzles that spray to filler 6 on feed pipe a3 and the feed pipe b4.Be provided with water circulating pump 5 among the cistern a7, this water circulating pump 5 is connected with feed pipe a3, feed pipe b4 and nozzle by pipeline, and cistern a7, water circulating pump 5, feed pipe a3, feed pipe b4 and nozzle have constituted water circulation system.Filler 6, feed pipe a3, feed pipe b4 and the water circulating pump 5, the cistern a7 that are located at filler 6 belows have constituted the direct evaporative cooling section of the first order.
The direct evaporative cooling section in the second level is set between filler 6 and the water fender 13.Comprise: be provided with high service pipe 9 between filler 6 and the water fender 13, be furnished with a plurality of high-pressure fog spray mouths 8 that spray to filler 6 on the high service pipe 9, also be provided with higfh-tension ceramics plunger displacement pump 12 and water filter 11 among the cistern b10 of bottom, this higfh-tension ceramics plunger displacement pump 12 is connected with water filter 11, high service pipe 9 and high-pressure fog spray mouth 8 by pipeline.
The direct Evaporative Cooling Air Conditioning unit of combined type of the present utility model adopts two direct evaporative cooling sections, and first direct evaporative cooling section is a packing section, and air directly contacts with wetting filling surface lowers the temperature to air.Second direct evaporative cooling section is the little mist section of high pressure, and the air of being lowered the temperature contacts with water lowers the temperature again to air, realizes the purpose to the bigger temperature drop of air.
Utilize the little mist of novel high-pressure, mainly be that the water that utilizes higfh-tension ceramics plunger displacement pump 12 to purify through water filter 11 in cistern b10 is pressurized to 7Mpa, be sent to the high-pressure fog spray mouth by the high service pipe again and make water fogging and produce droplet and can from air, absorb heat rapidly and finish vaporization and diffusion, thereby make through the processing of lowering the temperature again of the air of the direct evaporative cooling section of the first order.
Filler 6 is the mode of three-dimensional water distribution, water is extracted out from cistern a7 by water circulating pump 5, use water distribution system 4 at filler 6 upsides and front side water distribution uniformity, to dirty wetting filler 6 surfaces and form moisture film, processed air along continuous straight runs vertically carries out heat exchange by filler to water with it by the gravity effect.Filler 6 structures adopt sandwich structure, the fiber glass packing 17 of arranging by two metal packings 16 with between two metal packings 16 is formed, as shown in Figure 2, two metal packings 16 and fiber glass packing 17 are arranged side by side, and are furnished with a plurality of apertures in two metal packings 16.Metal packing 16 is directly made by aluminium foil and stainless steel, and the aperture that the sheet metal upper punch has can rough segmentation be joined the liquid on the thin slice, strengthens laterally mixing, the rill on the thin slice plays the effect of fine distribution liquid, has strengthened that liquid evenly distributes and the wettability of filler.The filler 17 that glass fibre is fired is made by the strong absorptive material of special ripple angle, filler absorbs water and spreads until drenched fully at material internal, steam is evaporated from the minute aperture of filler, and then Nei Bu moisture replenishes to minute aperture again, forms dynamic equilibrium.Both are big in conjunction with making filler have corrosion-resistant, fire-retardant, easy to clean, long service life, mass-transfer efficiency height, flux, and the characteristics that dispersed phase holdup is few have strengthened that liquid evenly distributes and the wettability of filler simultaneously again, have improved heat and mass efficient.
Have and to reduce processed air to take away the water fender 13 of the water yield identical with the structure of filler 6, form by two metallic plates and the glass mat between two metallic plates, arranged, two metallic plates and glass mat are arranged side by side, and are furnished with a plurality of apertures on two metallic plates.Water fender 13 can be isolated the water droplet that carries in the air, to reduce the water yield of taking away in the processed air.
Roughing efficiency air filter 1 can purify outdoor air, and filler 6 is played the proofing dust and protecting effect, improves the caloic exchange efficiency of filler 6 and air.
Water among the cistern b10 will be handled through water filter 11, to prevent high-pressure fog spray mouth 8 blockage phenomenon.
Pressure fan 14 is to send into processed air indoor to the room air processing of lowering the temperature through air outlet 15.
The course of work of the direct Evaporative Cooling Air Conditioning unit of the little mist combined type of the utility model filler-high pressure:
Outdoor air through air inlet 1 enter through roughing efficiency air filter 1 dust is filtered after, through the direct evaporative cooling section-filler 6 of the first order, water is extracted out from cistern a7 by water circulating pump 5 simultaneously, use feed pipe b4 at filler 6 upsides and front side water distribution uniformity, water by the gravity effect to dirty wetting filler 6 surfaces and form moisture film, processed air along continuous straight runs vertically carries out heat exchange by filler 6 with it to be realized air constant enthalpy temperature-fall period, the air of being lowered the temperature enters the little mist of the direct evaporative cooling section-high pressure in the second level, at this moment, higfh-tension ceramics plunger displacement pump 12 water that will purify in cistern b10 is pressurized to 7Mpa and makes water fogging at the high-pressure fog spray mouth 8 that passes to special construction by high service pipe 9 and produce droplet and directly contact further air to be lowered the temperature with air and add wet process.Carrying in the further processed air and can reduce the water yield of carrying secretly in the air after a large amount of water droplets enters water fender 13, sending into processed air indoor by pressure fan 14 through air outlet 15 at last.
