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 the compound structure of heat reclamation device, evaporation-cooled device and 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 machine unit shell, the first thermal wheel 3 and the second thermal wheel 4 are arranged in air-supply passage and return air channel, the new wind side 19 of the first thermal wheel 3 and the second thermal wheel 4 is arranged in air-supply passage, and the return side 24 of the first thermal wheel 3 and the second thermal wheel 4 is arranged in return air channel.Set gradually on machine unit shell wall between fresh wind port 1, disk filter 2, the first thermal wheel 3, the 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 rotation material filling type devaporizer 6 in air-supply passage, by new wind air intake direction return air inlet a5 is set; In return air channel, set gradually return air inlet b11, screen pack 12, direct evaporative cooler a13, water fender b14, the second thermal wheel 4, direct evaporative cooler b15, water fender c16, the 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 large specific area, heat exchange efficiency is high, air quantity scope that process is large, 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 form, between the new wind side of the first thermal wheel 3 and the second thermal wheel 4 and return side, demarcation strip 23 is set, sealing strip 20 is set on runner.Fig. 2 has provided thermal wheel 3 and has adopted the structural representation of vertical, thermal wheel 3 or 4 is placed in casing 25, driving heat exchanger by transmission device 21 fixing on box body wall and driving belt 22 rotates, sealing strip 20 is set on runner, vertical, rationally distributed, structure is compacter.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 subject to cooling (heating) (waiting wet cooling/heating), and under in a flash, just contact 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) just is able to cooling (heating), namely first carried out before carrying out other hot wet process 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 a heat recovery efficiency high, and flow resistance is little, the energy-saving effect outstanding feature.
The present invention adopts the compound structure of heat reclamation device, evaporation-cooled device and mechanical refrigeration device, can realize air etc. clammy but, cooling dehumidification.
Arrange return air inlet a5, rotation material filling type devaporizer 6, surface-type heat exchanger 7 in the passage of the new wind side 19 of the second thermal wheel; All adopt the primary retirn air system in winter and summer, reduced new wind load; Use summer the cryometer cooler to play the effect of cooling dehumidification, the use in winter direct evaporative cooler plays the effect of humidification.
Adopt water fender c16 to control the problem of water amount after adopting water fender b14, direct evaporative cooler b15 after 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.
What the new wind filter in structure of the present invention adopted is disk filter 2, when outdoor air flows through the disk wire side, impurity is delayed on wire side, pressure fan utilizes the dust in the impurity energy filtered air of rotary suction nozzle absorption 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 extend 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 the first thermal wheel 3, carry out the wet cooling processing such as the first order, again through the new wind side of the second thermal wheel 4, carry out the wet cooling processing such as the second level, then mix with the indoor return air of part through surface-type heat exchanger 7 and carry out the cooling dehumidification processing, the air after processing finally by pressure fan 9 is sent into indoor.Reduce the temperature of return air in the time of indoor return air process filter screen 12, direct evaporative cooler a13 filtration dust, after return side caloic exchange through the second thermal wheel 4, pass through again direct evaporative cooler b15, reduce the return air temperature that heats up, after return side caloic exchange through the first thermal wheel 3, finally will absorb the air exhausting of heat to outdoor by exhaust blower 17.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.
