Label 6 expressions match with bottom 4 and protecgulum 5 to form the loam cake of outdoor unit 1 housing.As shown in figure 10, the right flank of loam cake 6 is provided with the handle 17 that is used for moving or transmitting outdoor unit 1, and is having an otch 6b who is used for accepting the handle 16 on the protecgulum 5 on its left surface.The front of loam cake 6 has the otch 6c that the upper end of the outlet grid 5a that is used for preventing protecgulum 5 is covered, and also has plurality of projections 6d on the inner surface of this loam cake.In addition, also have an otch 6e in the back of loam cake 6, tube connector 12 extends through this otch, has some protuberance 6f that are meshed with the opening 5f of protecgulum 5 in the left surface inside of loam cake 6.
The back that has otch 6e of loam cake 6 all is inclined surface 6a along its whole width, flatly extend along inclined surface 6a Figure 20 so tube connector 12 can resemble, the outdoor unit that makes installation by its left surface near as shown in figure 23 the such building of balcony.In addition since connecting pipe 12 install along aforesaid inclined surface 6a, so can avoid connecting pipe 12 to protrude upward top above outdoor unit 1, so just can be assembled into stacked state to two outdoor units.
As shown in Figure 6, have between the upper end 3a of outdoor heat exchanger 3 and the loam cake 6 and highly be the space 7 of H.Electrical box 9 and the service valve 11 that links to each other with valve plate 10 are housed in space 7.The height H in space 7 is set for the height that is slightly larger than electrical box 9 or service valve 11.
In loam cake 6, electrical box 9 and service valve 11 along continuous straight runs are arranged side by side.Because electrical box 9 and service valve 11 along continuous straight runs are arranged side by side, consider that rainwater or fog enter situation the loam cake 6 from otch 6e, so spacer member 6g and loam cake 6 are made of one.Oneself closes the effect of a reinforcement spacer member 6g and protuberance 6d, thereby overcomes the load power that is applied by loam cake 6 tops.
Take up by gas box 9 and to be used to control compressor motor, the circuit of other electrical equipments of axial flow blower and outdoor unit 1 and indoor unit 2.As shown in Figure 1, the right part of electrical box 9 has and is used for the screw 9a that combines with valve plate 10, and its left part has screw 9c, with screw the screw 5e on the upper end, protecgulum 5 left side is combined with described screw 9c, this electrical box also has a projecting edge 9b, as shown in figure 12, there is a vertical plane portion that has screw 9c at this edge.
The vertical plane portion of the projecting edge 9b that stretches out from the left surface of electrical box 9 and the left surface of electrical box 9 at intervals make the space that limits the handle 16 that is used to take up on the protecgulum between them.
Electrical box 9 is contained on the outdoor heat exchanger 3 upper end 3a between the upper end that is in valve plate 10 left-hand end and protecgulum 5 left surfaces, this electrical box and outdoor heat exchanger upper end combined, they are connected together with screw.Electrical box 9 is made by metallic plate, thereby a hazardous noise that is produced by control circuit is sponged, and the hazardous noise that can avoid outdoor unit to send is sent to the outside.If electrical box 9 is made by plastic material, then use the inner surface or the outer surface of thin metal layer coating electrical box.
In addition, as shown in Figure 1, about 3/4 of the lateral dimension the when lateral length of electrical box 9 is set for outdoor heat exchanger 3 and is in confined state, and the size on its depth direction equals the size on the depth direction of outdoor heat exchanger 3 substantially, this is as shown in Figure 4.
The valve plate that label 10 expressions are made by metallic plate.Except the part of overlap joint on the electrical box 9, the width of valve plate 10 be about outdoor heat exchanger 3 width 1/4, the protuberance 10b that this valve plate draws out in addition.
Valve plate 10 is contained on the upper end 3a of outdoor heat exchanger 3, one end of this valve plate is fixed to screw on the screw 3d on the side plate 3b upper end of outdoor heat exchanger 3, and will be fixed to screw on the upper end of supporting member 20 of axial flow blower 8 with this fixed position valve plate other end from a distance, this supporting member is positioned at outdoor heat exchanger middle part in a lateral direction.As shown in figure 13, valve plate 10 has protuberance 10b and protrusion 10c and 10g.Protuberance 10b protrudes upward from the surface of par 10a, and it has the upper surface of flat horizontal, and rake is all arranged in the upper surface of protrusion 10c and 10g, makes some be higher than protuberance 10b, and also some is lower than protuberance 10b.
Have the opening 10d that is used for being connected respectively each valve plate 11 in the protrusion 10c of valve plate 10 and the rake of 10f, 10g and screw 10e, 10h.On the peripheral end of valve plate 10 bool is arranged.A spiral shell 10i who is combined by the screw 3d on the upper end of screw and outdoor heat exchanger side plate 3d is arranged on one of them bool, and other bool each all have a screw 107 that combines by the screw 5d on the upper end of screw and protecgulum 5 right flanks '.Valve plate 10 also has a prodger, a screw 10n and several screw 10m.This prodger has a screw 10k who is combined by the screw 20b on the supporting member 20 upper end 20a of screw and axial flow blower 8, by screw screw 10n is combined with the screw 9a of electrical box 9, with screw screw 10m is combined with hole on the handle 17, with fixed cover 6.
As shown in figure 14, supporting member 20 has a hook-type upper end 20a, and this upper end hangs over the upper end of outdoor heat exchanger 3, and it is fixing that they are engaged with each other, and outdoor heat exchanger is positioned at the back of outdoor unit 1, and the bottom 20d with supporting member is fixed on the bottom 4 simultaneously.By with the screw 20e on the 20d of bottom and the screw 4f on the protuberance 4e by screw combine the back just can be fixed to bottom 20d bottom on 4.Protuberance 4e 4 stretches out along the middle part of horizontal direction in the bottom.
As mentioned above, by each member is linked together, then just can connect together the back of outdoor heat exchanger 3 and two sides securely, thereby prevent the distortion of outdoor heat exchanger, and can select the rigging position of outdoor heat exchanger reliably by valve plate 10 and supporting member 20.In addition, valve plate 10, electrical box 9 has formed the girth member of outdoor unit housing after supporting member 20 and outdoor heat exchanger 3 cooperatively interact, and constituted add solid, formed the housing of practical outdoor unit 1 after protecgulum 5 and bottom 4 cooperatively interact.This has just guaranteed enough intensity.
Specifically, by the bottom 4 and the lower end of supporting member 20 are made up, the upper end 20a of supporting member 20 and the left part of valve plate 10 are made up, with the right part of valve plate 10 with make up near the upper end of the side plate 3b of the outdoor heat converter 3 of outdoor unit right flank and the lower end of side plate 3b and bottom 4 made up after, from the outdoor unit housing that looks previously with regard to quadrangularly.In addition, mesh on the top of the upper end 20a of supporting member 20 and the outdoor heat exchanger 3 at outdoor unit back, thereby be supported on this heat exchanger, so the upper and lower end face of the outdoor heat exchanger of seeing from the top 3 is all triangular in shape.Use the method, the quadrangle form of front and up and down the triangular shaped mutual combination back of both ends of the surface just can obtain leg-of-mutton rod structure, so just can improve intensity.
In addition, in another embodiment, and the height of the protecgulum 5 that the left end of the left part of bottom 4 and electrical box 9 combines should make bottom 4 and electrical box 9 be fixed on protecgulum 5 between them firmly, so just can save screw and other connectors in the left side of fixed chamber external heat exchanger 3, simultaneously, by improving intensity with combining of triangular column structure.
Label 11 expression service valves.The connecting pipe 12 that will be connected with the indoor unit (not shown) is linked service valve 11a, and 11b is so that cooperate the back to form kind of refrigeration cycle with indoor unit and outdoor unit 1.
Shown in Figure 15 to 17, each service valve 11 all has a refrigerant tubing connecting portion 11g, a connecting pipe connecting portion 11e, this body nut 11c and another this body nut 11f.Refrigerant tubing connecting portion 11g extends by the opening 10d or the 10g of valve plate 10, and the lower end of this connecting portion links to each other with refrigerant tubing 14 or 15 through soldering.Connecting pipe connecting portion 11e links to each other with the enlarging nut 12a of high or low pressure side connecting pipe 12, and outdoor unit links to each other with indoor unit by this connecting pipe 12.When being contained in inner cold-producing medium introducing valve opening and closing, unload this body nut 11c.After fixing connecting pipe and having finished other assembly works,, then unload this body nut 11f if air is purified by the operation inner valve.
But because the service valve 11b that links to each other with high-pressure side connecting pipe 12 does not need to be used for valve and this body nut 11f of purifying air, the service valve that adopts has all saved above-mentioned purifying valve and this body nut 11f usually.External diameter is less, being easy to crooked high-pressure side tube connector 12 is fixed to away from the valve 11b on the protuberance parts 10f of otch 6e, and with external diameter big than high-pressure side connecting pipe 12, and not steerable low-pressure side connecting pipe 12 is fixed near on the service valve 11a on the protrusion 1c of loam cake 6 otch 6e.
Fixedly the time, at first bigger external diameter, not steerable low-pressure side connecting pipe 12 is fixed on the service valve 11a, and then the high-pressure side connecting pipe is fixed on the valve in connecting pipe 12.This just can make the enlarging nut 12a of connecting pipe 12 utilize instrument to rotate under impregnable situation, and can be provided with along low-pressure side connecting pipe 12 being easy to crooked high-pressure side connecting pipe 12.So high and low pressure side connecting pipe 12,12 also can be extracted from outdoor unit after closely combining.
Service valve 11 vertically links to each other with the rake of protrusion, and as mentioned above, each protrusion is all made by control valve plate 10, and the closer to the side of the hot device of outdoor heat exchange, protrusion is just lowly more grand.In view of the above, as 13 couples of service valve 11a of the instrument of using, when this body nut of 11b was operated, instrument 13 was not subjected to the influence of the lateral margin 9a of electrical box 9.Certainly need adjusting service valve 11a and 11b setting height(from bottom) this moment with respect to rake.Specifically, should make service valve 11a, 11b is in the position that they are separated, and the distance between them is enough to tool using, and simultaneously, even when connecting pipe 12 links to each other with the connecting portion 11e of service valve, the enlarging nut 12a of connecting pipe 12 also can rotate with instrument.
In addition, in order to be easy to that the enlarging nut 12a of connecting pipe 12 is rotated with instrument, as shown in Figure 4, and with the protrusion 10c of valve plate 10, the position of 10g and be dimensioned to the rotation that does not allow enlarging nut 12a remove to stop instrument.
Label 14 expressions one end links to each other with service valve 11a, and the air inlet pipe (low pressure) that the other end links to each other with the pipeline of compressor 2.Label 15 expression blast pipes (high pressure).As shown in figs. 1 and 6, air inlet- outlet pipe 14,15 is with direction and service valve 11a perpendicular to valve plate 10 rakes, and the refrigerant tubing connecting portion 11g of 11b links to each other.
Label 14a, 15a represent the bend in the middle of the pipeline 14,15.Provide bend 14a, 15a based on following reason.Whenever with connecting pipe 12 and service valve 11a, 11b links to each other when enlarging nut 12a is rotated with instrument, and when this body nut 11c is rotated with instrument 13, service valve 11a, 11b also rotates slightly afterwards in the rotation of instrument 13 time.Even service valve in this way rotates, must prevent that also the weld seam of pipeline 14,15 is subjected to stress.Promptly adopt bend 14a, the purpose of 15a is to make pipeline 14,15 have flexibility, and alleviates rotation by deflection conduit.
With bend 14a, 15a is arranged in the space that is limited by valve plate 10 and outdoor heat exchanger 3, but can not be near the running track of axial flow blower 8.By effectively utilizing this space, pipeline 14,15 can vertically be connected on the rake of valve plate 10, and can provide bend 14a, 15a to these pipelines.
2,3 handles of describing outdoor unit 1 with reference to the accompanying drawings.Handle 16,17 is arranged on being in substantially of outdoor unit 1 top (promptly substantially at sustained height) in the conplane position, and is in the middle part (or basic consistent) of the degree of depth substantially with the center of gravity of outdoor unit.
Handle 16 on protecgulum 5 and handle 17 on loam cake 6.So when loam cake 16 was removed, handle 17 was thrown off simultaneously.Therefore, when linking connecting pipe 12 on the service valve 11, handle 17 is pulled down and is thrown off with loam cake 6, thereby makes attended operation will not be subjected to the obstruction of prominent handle 17 to service valve 11 when assembling, has improved processing characteristics thus.In addition, the space that handle 17 is designed to the service valve 11 by utilizing accommodating chamber external heat exchanger 3 tops is contained in this handle in the outdoor unit, and can be with this handle according to the top described cardinal principle centre position that is arranged on the outdoor unit degree of depth like that, this is will never be provided with like this because the outdoor heat exchanger 3 of handle is housed.
So, owing to can be arranged on and establish the corresponding to position of 1 center of gravity, outer unit by handle, thereby with handle is arranged on away from the outdoor unit center of gravity, situation about being located in the space (for example two spaces that limit between the angle of the sweep of outdoor heat exchanger and case back) that outdoor heat exchanger is not set is compared, just be easier to carry outdoor unit, weight suffered on the handle also can be equal.Can merotomize the loam cake that surrounds service valve 11.If be separated into and have only a part topped on service valve in the several portions, it is detachable that this part is made, and so just do not need to remove whole loam cake, and can operate easily.Although when rainy, carry out the tubulature operation in addition, also can avoid rainwater to fall on the circuit, eliminated potential faults thus.
In addition, except that part that surrounds service valve 11, can reduce the height of loam cake, thereby whole height is diminished.Under the situation that the upper cover part that will surround service valve 11 is separated, when connecting,,, improved service behaviour thus in addition so other parts are difficult for being affected because the height of loam cake is lower when the encirclement part of pulling down service valve and to connecting pipe.Label 18 expressions are used to protect the outdoor heat exchanger periphery to avoid the protection network of external action.Protection network 18 also can save.
The method of operating that outdoor unit 1 with said structure is installed will be described below.
As shown in Figure 6, it is little that the installation of outdoor unit 1 should make the gap (e) between outdoor unit 1 and the building walls 21.Therefore, after the connection of having finished connecting pipe, even will be from the side operation tool of wall 21 so as to lay down this body nut 11c, operation is installed valve and is improved cold-producing medium, but still can not get guaranteeing, so be difficult to carry out work in order to the space of operation tool.
In the present embodiment, should use the inclination angle of valve plate 10 rakes and highly be designed to avoid instrument 13 to be subjected to the influence of electrical box 9 end 9b, maintaining in the Handheld Division that makes instrument 13 under the condition above in the of electric rich 9 can the complete operation task, improves service behaviour thus.
Also connecting pipe 12 is screwed on service valve 11a, the 11b tightly with instrument 13.The service valve 11a of this moment, 11b will be designed to stretch out different height from valve plate 10, thereby is easy to carry out aforesaid operations.The adjacent protrusion 10c of otch 6e that promptly conveys loam cake 6 back is lower than the protrusion 10f away from otch 6e, just can prevent to be fixed to away from the connecting pipe 12 of the service valve 11 on the protrusion 10f of otch 6e to run into or especially near another protrusion 10c adjacent with otch 6e or be fixed to another service valve 11 on the protrusion 10c.If do not change the height of protrusion, just can change the height of service valve 11.
In addition, except the inclination angle and height of above-mentioned rake, make the longitudinal direction of rake of the protrusion 10c adjacent basic parallel with the back of outdoor unit 1 with otch 6e, and make away from the longitudinal direction of the rake of the protrusion 10f of otch 6e with respect to the back of outdoor unit 1 at angle, this is as shown in Figure 4.Utilize this arrangement, run into or very close protrusion or the service valve adjacent in order to prevent to be connected to otch 6e away from the connecting pipe 12 on the service valve 11b of otch 6e, the angle of inclination of rake and height are compared little with the situation that instrument moves freely, moving freely of instrument is to obtain behind angle of inclination by regulating rake and the height.So rake is less to help further improvement performance.
Finished after the above-mentioned attended operation, built loam cake 6 to surround electrical box 9 and maintenance valve member 11.
As mentioned above, although outdoor unit becomes the rectangular solid shape substantially, can become square substantially towards the side of protecgulum.This has just been avoided the preceding section mid point of the section mid point of axial flow blower air outlet slit grid away from protecgulum 5, therefore just can improve outer shape.
In addition, the stress that is applied to instrument B the time on the valve plate 10 is distributed on each parts, partly cause is with screw or other fixtures valve plate 10 to be fixed to the upper end of outdoor heat exchanger 3 side plates, the upper end of the upper end 20a of the supporting member 20 of axial flow blower 8, electrical box 9 and protecgulum 5, also have partly cause to be the left end of electrical box 9 is screwed to the upper end of protecgulum 5, so just can prevent valve plate 10 distortion.In addition, form protrusion, can further prevent this valve plate distortion by being controlled on the valve plate 10.
18-24 describes the installation situation of the outdoor unit with said structure with reference to the accompanying drawings.Figure 18 is the perspective view of the loam cake 6 that looks under the left-hand at the back; Figure 19 is the simplification sectional view that is used for illustrating when loam cake 6 is in connection status; Figure 21 to 23 is in the perspective view of confined state for each embodiment of explanation; Figure 24 is the schematic diagram of the outdoor unit installing space of embodiment of explanation and prior art.
As shown in figure 18, the lower end corner of the otch 6e that allows connecting pipe 12 to extend through is processed into circle, therefore as shown in figure 19, rotate around Embedded Division and make under this loam cake and the situation that protecgulum is connected by the right-hand member of loam cake 6 being embedded in the protecgulum 5 and its rear end, can prevent that loam cake 6 from contacting with tube connector 12.
According to top embodiment, when service valve 11 was equipped with on the top of outdoor unit 1, shown in Figure 21 to 23, outdoor unit 1 can be installed in from the very near place of building.The schematic diagram that is Figure 21 is represented: can be the right side of the outdoor unit of installing 1 near building, therefore, can make outdoor unit and as the gap l between the balcony of fabric structure 1Much smaller than the gap l between conventional outdoor unit and the balcony 4, service valve is equipped with in the side of conventional outdoor unit, and this is as shown in figure 24.Warp and traditional gap l 4(l 4=200mm) compare the gap l of this embodiment 1Be gap l 4Half, its value is for 100mm.
Gap l between outdoor unit 1 and the building walls 2Be 50mm, this and prior art identical.Because flow into gap l 1The air intake grid 5b of air by sidepiece suck and suck from the rear portion, institute is so that gap l 1Greater than gap l 2
Because the side of the outdoor unit 1 of this embodiment is provided with service valve, so that the lateral length reduction corresponding to the size of service valve, thereby as shown in figure 21, has avoided building window to be affected.Specifically, the width of the outdoor unit 1 of this embodiment is 595mm, and length is the gap l of 100mm 1Add the width of 595mm, it equals 695mm (about 700mm), and this value is littler to the distance (700 to 800mm) of window than the balcony in general house, so can avoid the balcony of building to be affected.
The schematic diagram of Figure 22 represents that the outdoor unit of installing 1 leaves a space l at its right flank and the between the walls of building 1In the case, deduct the space that 695mm (about 700mm) just obtains the 100mm between outdoor unit 1 left surface and the balcony by total balcony degree of depth 800mm, the needs of circulation of air are satisfied in this space.The degree of depth that in fact certain balcony is arranged is greater than 800mm, yet the space l of the conventional outdoor unit of service valve is equipped with in the side 4Still than the space l of present embodiment 1Big 100mm.This just requires the balcony degree of depth that 900mm is arranged, so conventional outdoor unit can not be contained in the common balcony like this.
According to installation situation shown in Figure 22, though from the door to the balcony or other the mark things distance very little (for example 300mm), the installation of outdoor unit be not subjected to yet the door influence.The situation that is mounted in left side in the balcony shown in Figure 22, in any case, even the right edge in balcony can be installed in a like fashion.The schematic diagram of Figure 23 represents that outdoor unit 1 is installed in the situation in the left side in the balcony, leaves space l between the back of outdoor unit and the building walls 2
In this case, when the connecting pipe 12 that handle links to each other with indoor unit is linked on the service valve 11, connecting pipe 12 if prebend, then be fixed to connecting pipe 12 on the service valve 11 after, connecting pipe 12 can be provided with along the inclined surface 6a of the loam cake 6 that is connected.So can avoid connecting pipe 12 to protrude upward top, thereby need not pay special attention to improve connecting pipe 12 and building harmony in appearance above outdoor unit 1.In addition, owing to connecting pipe 12 is provided with along inclined surface 6a, thus can prevent that as mentioned above connecting pipe 12 from protruding upward the top above outdoor unit 1, thereby two outdoor units 1 can be installed stackedly.
In this embodiment, as mentioned above,, then can save installing space, form the profile of a rectangular solid because service valve does not stretch out from the side.Thereby be easy to make its outward appearance and building to coordinate.
In the above-described embodiments, service valve 11 is tilted setting.But shown in Figure 25 or 26 (local amplification view, expression outdoor unit upper right quarter), the mode that service valve is installed should make cold-producing medium introduction valve (not shown) and this body nut as the service valve operating parts rotate in level or vertical plane.
Specifically, as shown in figure 25, when this body nut as the operating parts 11a ' of service valve and 11b ' rotates in horizontal plane, the operation of rotating this body nut by instrument is subjected to the influence of electrical box 9, make the rotational angle of tool operation reduce to about 90 °, but with prior art in service valve is housed in the side outdoor unit to compare service behaviour better.In addition, because the top opens, so when connecting pipe 12 was connected, its service behaviour was similar to embodiment shown in Figure 6 and very outstanding.If do not adopt Fig. 1 and shown in Figure 6 be widely used for a long time and during very general linear general utility tool always, if adopt widely used in recent years L shaped instrument, then Cao Zuo rotational angle resembles and becomes 150 Fig. 6 embodiment and spend to 180 and spend.So service behaviour is fairly good as Fig. 6 embodiment.
As shown in figure 26, when service valve operating parts 11a " and 11b " rotates in vertical plane, electrical box 9 is not rotated in the process of instrument rotating operation spare, so the instrument rotational angle reaches about 120 degree, compares service behaviour with the prior art that service valve is equipped with in the side and is greatly improved.The service behaviour that connecting pipe 12 is connected is just the same with 25 illustrated embodiments with Fig. 6 very good.
The valve plate 10 of control shown in Figure 25 and 26 ' and 10 " time, the protrusion 10c and the 10f of made protrusion and valve plate shown in Figure 13 10 are basic identical.Determine the size of protrusion with the above-mentioned same procedure relevant with Fig. 4, when with instrument the nut 12a of connecting pipe 12 being operated when it is rotated, protrusion must not be subjected to the influence of this operation.
As mentioned above, can obtain a lot of effects according to the foregoing description.Some typical effects will be described below.Because service valve 11 is contained in the top, be to finish different operations at the outdoor unit top with the difference of the prior art that service valve is contained in the side after relatively: comprise and fixedly connected the operation of pipeline 12, connect and field-strip valve 11a, 11b, 11a ', 11b ', the operation of this body nut of 11a " and 11b ", and make this body nut 11c unload the back by rotating opening that makes the cold-producing medium introducing valve that is contained in each service valve or the operation of closing this valve.So, can operate safely and effectively thus with regard to not operating with affined posture.
Because service valve 11 is obliquely installed, so the rotary motion trace of instrument 13 is not subjected to the influence of electrical box 9.Even thereby adopt the general utility tool of extensive use on wall, also can operate, also can avoid electric box 9 and wall to be had a strong impact on simultaneously.So favorable working performance, and do not need to prepare any specific purpose tool.
At valve plate 10, outdoor heat exchanger 3, axial flow blower support plate 20 and electrical box 9 there is no need to prepare any independent reinforcement for housing in conjunction with among the embodiment that constitutes the reinforcement that guarantees outdoor unit 1 casing rigidity.So the amount of size that can reduce is corresponding to independent reinforcement size, and can reduce the assembled portion number of packages.Shorten built-up time.
The local location of valve plate 10 has protrusion, and each protrusion all has the rake that diminishes towards the side of outdoor unit 1, and service valve 11 substantially vertically is fixed on the rake.This helps guaranteeing fixing to connecting pipe 12, guarantees service valve 11 is connected on the valve plates 10, and helps reducing the setting height(from bottom) of service valve 11.Therefore, the spatial altitude between the upper end of outdoor heat exchanger 3 and the loam cake 6 can be less.
The valve plate 10 that metallic plate is drawn into can strengthen the intensity of this valve plate self, this valve plate is fixed to the upper end of external heat exchanger 3 sides and is suspended on the supporting member 20 of outdoor heat exchanger 3 back, thereby increase intensity between each bonded block.In addition, service valve 11 is linked the protrusion of valve plate 10,, therefore do not need reinforcement just can obtain the intensity of external force resistance so the external force that is applied to when connecting pipe 12 is linked to each other with service valve 11 on the valve plate 10 is assigned on outdoor heat exchanger 3 and the supporting member 20.
Can be clear that from above according to the present invention, because service valve is contained in the top of outdoor unit, then can guarantee have the outdoor unit top of large space to carry out various operations, these operations comprise: the operation of fixedly connected pipeline and according to the fixing operation of connecting pipe, and through the operation that the conventional outdoor unit of service valve is relatively regulated service valve being housed with the side.So just need under affined posture, not operate, thereby can operate safely and effectively.
In addition, because service valve is equipped with at the top of outdoor unit, be equivalent to the distance of service valve tab length and operate the required space of wanting with regard to not vacating one, so just can install near building ground the side of outdoor unit to outdoor unit at sidepiece.In addition, be that with the prior art difference service valve does not stretch out from the side, thereby saved installing space.
Valve plate, outdoor heat exchanger, axial flow blower and supporting member and electrical box all are used as the intensity that reinforcement guarantees the outdoor unit housing, so do not need to prepare any independently reinforcement for housing.This can make size reduce, and assembling parts reduces, and shortens built-up time.
