Abstract
The utility model relates to a low noise discharging air device of the wind cooling type central air conditioning has a low noise waterproof centrifugal fan arranged in the close space formed by two fin type heat exchangers and a sealplate. An air discharging cone having a wind-cone type muffler device is immovably arranged on the upper sealplate. A flexible contraction band is connected between the upper end of the centrifugal fan and the air discharging cone. Because the noise made by the centrifugal fan is much lower than the noise made by the axial-flow fan, the noise is very low when discharging outdoor by further treatment of the wind-cone type muffler device. The utility model greatly lowers the effect of the noise to the environment, therefore widens the applied range of the wind cooling type central air conditioning.
Description
Technical field
The utility model relates to the heat pump technical field, particularly relates to a kind of air exhausting device of air-cooled central air-conditioning unit.
Background technology
Air-cooled central air-conditioning unit all is to utilize air exhausting device to drive air to flow, thereby by finned heat exchanger and air heat exchange.Because the restriction of structure, the air exhausting device of existing air-cooled central air-conditioning unit mostly adopts axial flow blower, the axial flow blower air quantity is big, simple in structure to be its advantage, but its blast is less, noise is bigger, during use surrounding environment is caused certain influence, limited the range of application of air-cooled central air-conditioning unit, so the noise problem of air-cooled central air-conditioning unit is to perplex manufacturer always.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides a kind of noise low air-cooled central air-conditioning unit air exhausting device.
For achieving the above object, the air-cooled central air-conditioning unit of the utility model low noise air exhausting device, be in the enclosure space of forming by two finned heat exchangers and sealing plate, centrifugal blower to be installed, on the sealing plate on top, be installed with the air draft tube, between centrifugal blower upper end and air draft tube, be connected with flexible telescopic band.
Air-cooled as mentioned above central air-conditioning unit low noise air exhausting device also is provided with the air duct silencing apparatus in its air draft tube.
Air-cooled as mentioned above central air-conditioning unit low noise air exhausting device, its centrifugal blower is a low noise waterproof centrifugal blower.
Because the noise of low noise waterproof centrifugal blower own is just than little many of axial flow blower, air enters in the enclosed cavity by finned heat exchanger, the noise that is produced by the air draft of low noise waterproof centrifugal blower reduces greatly, noise is after the air duct silencing apparatus is further handled, it is very little to be discharged to the noise that produces when outdoor, thereby reduced the influence of NOISE ON ENVIRONMENT greatly, widened the application of air-cooled central air-conditioning unit.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Accompanying drawing illustrated embodiment, the utility model are that the low noise waterproof centrifugal blower 2 that can buy on the market is installed in the enclosure space of being made up of two finned heat exchangers 1 and sealing plate 6, and centrifugal blower 2 is fixed on the sealing plate 6 of bottom.On the sealing plate 6 on top, be installed with air draft tube 5, be provided with air duct silencing apparatus 4 in the inboard of air draft tube 5.The sealing plate 6 of corresponding air draft tube 5 lower ends and between centrifugal blower 2 upper ends, being flexible coupling by flexible telescopic band 3, thus vibrating noise between the two avoided.
