Fig. 2 is the utility model heat exchange principle figure.
As depicted in figs. 1 and 2, housing 1, mount pad 2, new wind entrance 3, new wind outlet 4, uselessly enters mouthfuls 5, useless discharge orifice 6, full heat exchanging core 7, new wind air channel 8, useless air exhausting duct 9, new wind blower fan 10, useless exhaust fan 11, air-conditioning unit 12.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, guideway vehicle aeration device described in the utility model, be applied on the guideway vehicles such as subway, the air-conditioning unit 12 of the guideway vehicles such as subway is generally fixedly mounted on the car body of top board top, guest room, and this aeration device is also fixedly mounted on top board (not shown) top, guest room.
This aeration device comprises a housing 1, on housing 1, be provided with four mount pads 2, mount pad 2 is fixedly connected with by fasteners such as bolts with the car body of guest room top board top, in the end of one end, every joint compartment, this aeration device is set, and also can in the end at two ends, every joint compartment, arrange one.This aeration device can also directly be fixedly mounted on the shell of air-conditioning unit 12.This aeration device can independently be installed also and can be installed together with air-conditioning unit 12, and user can arrange arbitrarily according to the needs of guest room top board superjacent air space, flexible, is subject to space constraint less.
On housing 1, have new wind entrance 3, new wind outlet 4, useless mouth 5, the useless discharge orifice 6 of entering, in housing 1, be provided with full heat exchanging core 7, new wind air channel 8, useless air exhausting duct 9, new wind blower fan 10 and useless exhaust fan 11.
Wherein, new wind entrance 3 is arranged on a sidewall of housing 1, and new wind blower fan 10 is installed in the inner side of new wind entrance 3, and new wind entrance 3 connects new wind outlet 4 by new wind blower fan 10 and new wind air channel 8 successively, and new wind outlet 4 is arranged on another sidewall of housing 1.New wind outlet 4 can access by air channel the air-conditioning unit of vehicle, first mixes with indoor return air, then passes through evaporator heat exchange, finally enters in compartment.Or, new wind air outlet (not shown) can be set on guest room top board, new wind outlet 4 is directly connected with new wind air outlet by air channel, and new wind is without evaporator, directly in outdoor introducing compartment.
Useless enter mouthfuls 5 and be arranged on the diapire of housing 1, useless exhaust fan 11 is arranged on the inner side of useless discharge orifice 6, uselessly enters mouthfuls 5 and by useless air exhausting duct 8, is connected the discharge orifice 6 that gives up with useless exhaust fan 11 successively.On guest room top board, offer the useless air port (not shown) that flows back to, useless useless the entering between mouth 5 that flows back to air port and aeration device at guest room top board do not arrange air channel, but utilize the space of top board top, guest room as useless air exhausting duct, indoor return air flows back in the space that air port enters top board top, guest room by useless, under the effect of useless exhaust fan 11, from the useless mouth 5 that enters, enter again, finally from useless discharge orifice 6 delivery chamber.
New wind air channel 8 is all communicated with full heat exchanging core 7 with useless air exhausting duct 9, in full heat exchanging core 7, interchange of heat is carried out in new wind and useless air draft, when outside air temperature is lower in the winter time, new wind absorbs the heat of useless air draft, and when summer, outside air temperature was higher, utilize useless air draft to absorb the heat of new wind, make new wind in entering compartment or before air-conditioning unit, just improve or reduced the temperature of new wind, the new wind entering in compartment is carried out to precooling preheating, new wind is entered in compartment to approach the state of room temperature, reduced the new wind load of air-conditioning unit, and then improved the Energy Efficiency Ratio of air-conditioning unit.And when introducing new wind, indoor gas is discharged, reduced the pollution of room air, formed the reasonable circulation of air conditioner surroundings air-flow, completed the new wind air draft displacement of air conditioner surroundings, build the respiratory system of guest room, impel room air to be rich in sufficient oxygen, for passenger, maintain vital movement and breathe.
In this aeration device, be provided with new trend controller, new wind blower fan 10 and useless exhaust fan 11 are all connected with new trend controller, by new trend controller, control its start-stop and rotating speed.In new wind air channel 8, useless air exhausting duct 9, be also respectively arranged with new wind air door and useless exhaust door, new wind air door is also connected with new trend controller with useless exhaust door, is controlled switching and the aperture of each air door, to control resh air requirement and useless exhaust air rate by new trend controller.
