The specific embodiment
Embodiment 1
As shown in Figure 2, a kind of multiple duct air-conditioner outdoor unit is provided with a casing 20, is provided with heat exchanger 22, blower fan 24 and compressor 29 in this casing 20;
Between heat exchanger 22 and compressor 29, be provided with median septum 26, between heat exchanger 22 and median septum 26, be provided with first back of the body net 25, be provided with second back of the body net 23 at the opposite side of heat exchanger 22;
Described casing 20 is provided with the air-inlet window 27 that allows extraneous air flow into compressor 29.
Described heat exchanger 22 is a U type structure.
The profile of off-premises station is a casing 20, and this casing 20 is to possess the front, the back side, two sides, the hexahedron on top cover and chassis.In addition, right plate 28 front portions of casing 20 are provided with air-inlet window 27, and median septum 26 is 22 right side front ends from right plate 28 front portions to heat exchanger, and air sucks through left side back of the body net 23, back net 25 and right plate air-inlet window 27.
Form two air guiding portions between above-mentioned right plate 28 anterior air-inlet windows 27 and back of the body net 23,25 and the heat exchanger 22.
Possesses the air inlet 21 that allows extraneous air flow into casing 20 inside on the casing 20.The heat exchanger 22 that present embodiment provides takes the shape of the letter U, and can significantly increase the heat exchange area of heat exchanger like this.The heat exchange property that the air current flow of heat exchanger and speed will influence heat exchanger but flow through in casing 20 inside, traditional off-premises station air flows into casing 20 through back of the body net, and without heat exchanger 22, heat exchanger 22 of the present utility model has special air channel.This air channel is made up of second back of the body net 23, first back of the body net 25, median septum 26 and casing 20, is used for cooling heat exchanger 22, and the air channel flow process is shorter, and air quantity is big.
The median septum 26 that also possesses its support in the casing and isolate the air channel effect.The median septum position of conventional outdoor unit is from the front panel to the right plate, outdoor heat exchanger 22 and compressor 29 are thoroughly isolated, the position of the off-premises station median septum 26 that present embodiment provides is different with the position of the median septum of prior art, the box house heat exchanger outside is divided into two parts, portion of air is passed through heat exchanger 22 through air-inlet window 27 inlet flow overcompression machines 29 backs, a part is from back of the body net 23 and 25 air intakes, and the heat exchanger 22 of flowing through forms two air guiding portions.
The off-premises station that present embodiment provides is that compressor 29 is provided with the air channel, and compressor 29 can be emitted heat in the course of the work, can improve the efficient of system to the cooling of compressor 29.At process of refrigerastion, the cold-producing medium evaporation back in the indoor set flows into off-premises station, is compressed into high pressure conditions in compressor 29, flow through outdoor heat exchanger 22 again, carry out heat exchange with it and liquefy, and the heat that heat exchanger 22 produces, by taking away of air-flow composition, divide liquefaction refrigerant charging.The compressor liberated heat raises the gas flow temperature through this part, because the temperature difference reduces to be unfavorable for the liquefaction of cold-producing medium, its heat can be controlled and the area of the heat exchanger of flowing through in special air channel, and negative effect is controlled at minimum during again through heat exchanger.Heat in the process, the cold-producing medium liquefaction back in the indoor set flows into off-premises station, becomes the liquid of low-temp low-pressure behind throttling arrangement, flow through outdoor heat exchanger again, carry out the heat exchange generating gasification with it, cold-producing medium absorbs near the Cryogenic air the heat heat exchanger, taken away by air-flow, cold-producing medium is fully gasified.The flow through higher gas of temperature of compressor has increased the gasification that the temperature difference helps cold-producing medium, can improve efficiency of heat exchanger.
Casing also possesses the air outlet 21 that the air flow stream of allowing goes out casing.Air outlet 21 is that the heat that is used for box house heat exchanger 22 is discharged, i.e. the heat of heat exchanger 22 generations, and the air-flow that is flow through heat exchanger 22 is taken away.By being located at the air outlet of casing front, discharge air.This air is blown out by the fan of box house, and carries out heat exchange when heat exchanger 22.
Off-premises station casing inside also is provided with blower fan 24.This blower fan 24 can form the air-flow of the heat exchanger 22 of flowing through, and allows outside air enter casing 20 inside, and leaked-in air is discharged by air outlet.
To having the as above off-premises station molar behavior of structure, be described as follows below.During air conditioner refrigerating work, the heat exchanger of indoor set and blower fan are to indoor output cold air.In the heat exchanger of indoor set, absorb the vaporized cold-producing medium of heat, flow in the off-premises station by the coupling part.And after cold-producing medium was arranged on compressor compresses in the off-premises station casing, flowing into outdoor heat exchanger carried out heat exchange, is cooled to liquid state again.At this moment under the effect of blower fan, can form the heat exchanger 22 of flowing through, flow to the air-flow of air outlet.And the heat that this air-flow produces heat exchanger 22, outwards heat radiation.In the present embodiment, under the effect of axial flow blower, can form air inlet (comprising back of the body net and air-inlet window) air intake and flow to the air-flow of air outlet through condenser, owing to be provided with a plurality of air inlets, can between heat exchanger 22 and air outlet 21, form three airflow guide, compressor 29 and whole heat exchanger 22 are cooled off.In this course, the cold-producing medium that is liquefied in heat exchanger flows to indoor set again by connecting portion, carries out heat exchange in indoor set.
More than multiple duct air-conditioner outdoor unit provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, part in specific embodiments and applications all can change.In sum, this description should not be construed as restriction of the present utility model.
