The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
The twin-runner type evaporative cooling of band automatic dust absorption of the present invention and mechanical refrigeration combined air conditioner unit adopt heat reclamation device, evaporation-cooled device and the compound structure of mechanical refrigeration device, adopt thermal wheel.Structure as shown in Figure 1, comprise the air-supply passage and the return air channel that be arranged in parallel in the machine unit shell, first thermal wheel 3 and second thermal wheel 4 are arranged in air-supply passage and the return air channel, the new wind side 19 of first thermal wheel 3 and second thermal wheel 4 is arranged in the air-supply passage, and the return side 24 of first thermal wheel 3 and second thermal wheel 4 is arranged in the return air channel.Set gradually on the machine unit shell wall between fresh wind port 1, disk filter 2, first thermal wheel 3, second thermal wheel 4, rotation material filling type devaporizer 6, surface-type heat exchanger 7, water fender a8, pressure fan 9 and air outlet 10, the second thermal wheels 4 and the rotation material filling type devaporizer 6 in the air-supply passage, by new wind air intake direction return air inlet a5 is set; In the return air channel, set gradually return air inlet b11, screen pack 12, direct evaporative cooler a13, water fender b14, second thermal wheel 4, direct evaporative cooler b15, water fender c16, first thermal wheel 3, exhaust blower 17 and exhaust outlet 18 by return air air intake direction.
Runner is a kind of heat exchanger with high heat recovery efficiency, it realizes the heat transmission by the continuous rotation of inner circular filler, has very big specific area, the air quantity scope of heat exchange efficiency height, processing is big, good integrity, flexible arrangement, heat transfer good stability, controlled organic efficiency, air draft and the new wind of heating replace reverse flow and cross runner, have the characteristics such as effect of self-cleaning.The structure of thermal wheel disclosed by the invention as shown in Figure 2, return side 24 and casing 25 by the new wind side 19 of thermal wheel, sealing strip 20, transmission device 21, driving belt 22, demarcation strip 23, thermal wheel are formed, between the new wind side of first thermal wheel 3 and second thermal wheel 4 and the return side demarcation strip 23 is set, sealing strip 20 is set on the runner.Fig. 2 has provided thermal wheel 3 and has adopted the structural representation of vertical layout, thermal wheel 3 or 4 is placed in the casing 25, driving heat exchanger by transmission device 21 fixing on the box body wall and driving belt 22 rotates, sealing strip 20 is set on the runner, vertical layout, rationally distributed, structure are compact more.Thermal wheel need not centralized arrangement, and more conventional heat exchanger is more convenient, simple, can move continuously for a long time, and the thermal wheel flexible arrangement.The indoor exhaust wind of temperature low (height) is during by the air draft side, core is subjected to cooling (heating) (waiting wet cooling), and to down in a flash, just contacts with air draft, the core that is cooled after (heating) just forwards the Xin Feng district to, contacts with the fresh air that enters.So the fresh air of high temperature (low temperature) is just cooled off (heating), promptly before carrying out other hot wet process, carry out earlier pre-cooled (heating), thereby satisfy cold recovery in summer, the requirement of recuperation of heat in winter.The present invention adopts thermal wheel to replace existing plate-fin heat exchanger, has the heat recovery efficiency height, and flow resistance is little, the Remarkable Energy Saving characteristics.
The present invention adopts heat reclamation device, evaporation-cooled device and the compound structure of mechanical refrigeration device, can realize air etc. clammy but, cooling dehumidification.
In the passage of the new wind side 19 of second thermal wheel, arrange return air inlet a5, rotation material filling type devaporizer 6, surface-type heat exchanger 7; Winter and summer are all adopted the primary retirn air system, have reduced new wind load; Use summer the cryometer cooler to play the effect of cooling dehumidification, use winter direct evaporative cooler to play the effect of humidification.
Adopt the problem of water fender c16 after adopting water fender b14, direct evaporative cooler b15 behind the direct evaporative cooler a13, prevent that water droplet from transferring to the new wind side of runner by entering the return side runner, thereby increase the water capacity of new wind with the control water amount.
What the new wind filter in the structure of the present invention adopted is disk filter 2, when outdoor air flows through the disk wire side, impurity is delayed on the wire side, pressure fan utilization rotation suction nozzle is absorbed the dust in the impurity energy filtered air of detention on wire side, new wind side to runner is carried out the proofing dust and protecting effect, with the heat exchange efficiency that improves heat exchanger and prolong its service life; And return air filter has only adopted screen pack 12 tentatively to filter, because all be provided with direct evaporative cooler two thermal wheel back, direct evaporative cooler has not only played cooling effect, and is good wet filter.
The operation principle of air-conditioning unit of the present invention is: after outdoor new wind filters dust through disk filter 2, new wind side by first thermal wheel 3, carry out wet cooling processing such as the first order, again through the new wind side of second thermal wheel 4, carry out wet cooling processing such as the second level, mix with the indoor return air of part then and carry out cooling dehumidification through surface-type heat exchanger 7 and handle, after the air of pressure fan 9 after will handling sent into indoor.Indoor return air reduces the temperature of return air through filter screen 12, when direct evaporative cooler a13 filters dust, after the return side caloic exchange through second thermal wheel 4, pass through direct evaporative cooler b15 again, reduce the return air temperature that heats up, after the exchange of the return side caloic of first thermal wheel 3, finally the air that will absorb heat by exhaust blower 17 drains into outdoor.The new wind side of thermal wheel and the return side of thermal wheel are during in the winter time with summer operation, and effect is opposite, thereby outdoor new wind is carried out The pre-heat treatment, reaches the purpose of recuperation of heat.
