Referring to Fig. 2,, need be provided with one and be used for centrifugal cooling fan 40 is fixed on fan support on the off-premises station cabinet for the vibration that prevents fan impacts system.This support member comprises that one is used for strengthening and supports the blower tray 42 at deliverying unit 11b edge and one and is used for side with centrifugal cooling fan 40 and is fixedly installed to fan bracket 44 on the blower tray 42.The shape of fan bracket 44 can be according to the installation direction of centrifugal cooling fan 40 and is different.In addition, when the off-premises station cabinet is divided into and sucks the corresponding suction cabinet of unit 11a and during with the corresponding discharge cabinet of deliverying unit 11b as mentioned above, blower tray 42 can be strengthened and support and discharges cabinet.Reference numeral 46 representatives are installed in the fan part of centrifugal cooling fan 40 fronts.
In addition, the control box 50 that is used for controlling off-premises station 10 operations is installed in unit, the rear surface 12c, preferably be installed in and suck in the unit 11a, the refrigerant tube passage that is used for carrying at the refrigerant pipe and a valve assembly 52 of the refrigerant gas that indoor set evaporates and is used to discharge the refrigerant of condensation in off-premises station 10 is installed below control box 50.
Operation principle to built-in type outdoor unit for air conditioner is elaborated below.At first, the refrigerant pipe by valve assembly 52 carry, be transported to Air-cooled Condenser 30 after compressing by compressor 20 from the refrigerant gas of indoor set.Because centrifugal cooling fan 40 is being worked, the slit of the blade of louver window in the suction area 7a and front surface unit 60 inhaled airs of off-premises station cabinet are by by top cover 32a, the passage that 32b and 32c and side cover 34a and 34b form is flowed through equably and is formed at three lip-deep fin of Air-cooled Condenser 30, the refrigerant gas that inserts the condenser pipe between the fin from flowing through obtains condensation heat, and high temperature air discharges by the slit of centrifugal cooling fan 40 from the blade of louver window 8 of discharge area 7b then.
When off-premises station be installed in building outer within the walls the time, preceding suction/discharge formula off-premises station can be installed on the tall and big apartment building as shown in Figure 1, according to the development trend of city and high-rise commercial building in recent years, the structure of adjacent house type is symmetrical, and such building has become a kind of representational life style.Under the situation in the side angle that outdoor unit chambers is installed in the outside open space of building falls, the noise that produces when considering the off-premises station operation and the utilization of the building interior space, because the structural configuration in building is symmetrical, so the off-premises station of adjacent room also is adjacent one another are.
Figure 3 shows that an apartment building.The outdoor unit chambers in every layer A, C and E room is on the right side, because the structure in building is symmetrically arranged, so adjacent with the E room with every layer A, C respectively B, the D and the outdoor unit chambers in F room are arranged on the left side.Therefore, outdoor unit chambers 100 and 102 is adjacent one another are.According to notable attribute of the present invention, the discharge direction of the off-air after outdoor unit chambers 100 and 102 heat exchanges of discharging is (directions X Fig. 3) of discharging to away from the direction of the most contiguous off-premises station.As mentioned above, discharge the preceding suction/discharge formula off-premises station of the off-air after the heat exchange from the top of outdoor unit chambers 100 and 102 for sucking fresh outdoor air from the bottom of outdoor unit chambers 100 and 102, fresh outdoor air is pressed shown in the direction of arrow Y, be drawn in outdoor unit chambers 100 and 102 from the slit between blade of louver window, and the off-air of heat exchange in outdoor unit chambers 100 and 102 is pressed shown in the direction of arrow X, discharges by the slit between the shutter.
Therefore, the off-air after the heat exchange that off-premises station is discharged seldom can be drawn into the suction unit of off-premises station of the suction unit of the suction unit of off-premises station, adjacent off-premises station or a last floor again.Promptly, if fresh outdoor air does not suck by sucking the unit, and the off-air of the high temperature of discharging from off-premises station or other off-premises station is when being inhaled into again by sucking the unit, and the heat exchanger effectiveness of Air-cooled Condenser can reduce inevitably, and the present invention promptly can address this problem.
Preferred embodiment shown in Figure 4 can achieve the above object.The direction of rotation of the centrifugal cooling fan 40b that the direction of rotation that is installed in the centrifugal cooling fan 40a in the outdoor unit chambers 100 in A room and the outdoor unit chambers that is installed in the B room 102 are interior is opposite.Off-air after the heat exchange of centrifugal cooling fan 40a and 40b discharge is discharged to the direction away from the most contiguous off-premises station respectively.Therefore, the off-air of discharging from every off-premises station seldom can be drawn in this off-premises station or in the adjacent off-premises station again.According to the present invention, the off-air of off-premises station after with heat exchange is by having the centrifugal cooling fan of higher capacity, and preferably the centrifugal cooling fan (preferably leafy chip cooling fan) greater than 6m/s discharges to the direction away from the most contiguous off-premises station.Even the wind of skyscraper or against the wind when the direction of arrow Z blows, the off-air of discharging from off-premises station can not be inhaled into this off-premises station or the adjacent off-premises station again.
Figure 5 shows that an embodiment of off-premises station mounting structure of the present invention.Here, the off-premises station 10a in A room must be installed at a distance of the nearer position of partition wall between room A, the B, but for a just explanation, the position is far away apart from partition wall shown in the figure.Referring to Fig. 5, the discharge direction of the leafy chip cooling fan 40a in A room is opposite with the discharge direction of the leafy chip cooling fan 40b in B room.For this reason, as shown in Figure 4, the direction of rotation of the leafy chip cooling fan motor in A room must be opposite with the direction of rotation of the leafy chip cooling fan motor in B room.
In the above-described embodiments, with the hole up/under leafy chip cooling fan as centrifugal cooling fan.But, even use difform fan, if air that guiding discharges is installed to the air-deflector of discharging away from the direction of the most contiguous off-premises station, so only the direction by the control air-deflector just can make the discharge direction of the off-air after the heat exchange of the most contiguous off-premises station keep opposite each other.
Discharge resistance when discharging air in order to reduce deliverying unit, as the blade of louver window 8 of the room B of Fig. 5 ' shown in, the blade of louver window of deliverying unit can vertically form.That is, when the waste gas after the heat exchange is discharged from, can be by blade of louver window channeling conduct away from the most contiguous off-premises station.Here, the blade of louver window of opening direction and B room of the blade of louver window in A room to open direction opposite.
When the discharge direction of two adjacent off-premises stations is controlled, as shown in Figure 3, the heat-exchanged air of discharging from an off-premises station (for example off-premises station in C room) seldom can be inhaled into adjacent off-premises station (for example off-premises station in D room) or with it suction unit of upper and lower adjacent off-premises station (off-premises station in E, F, A or B room).Therefore, can improve the heat exchanger effectiveness of all off-premises stations that are installed on the apartment building.
The front is formed at the off-premises station that bottom, discharge area be formed at top to suction area and is illustrated.Be positioned at top and discharge area is positioned at the off-premises station of bottom for suction area, its principle is identical.
In addition, Figure 6 shows that suction area and discharge area are formed at the off-premises station of the left and right sides respectively.In the same way, the discharge direction of the off-air after the heat exchange is a directions X, discharges to the direction away from the most contiguous off-premises station, and the suction direction of fresh air is the Y direction.Therefore, the off-air of discharging from every off-premises station almost can not be drawn into the adjacent off-premises station of the adjacent off-premises station of this off-premises station, same floor or different floors again.With centrifugal cooling fan, preferably leafy chip cooling fan is as cooling fan, and off-premises station shown in Figure 6 can reach with discharge area and suction area and be separately positioned on/the identical effect of off-premises station of following direction.Referring to Fig. 6, when the suction unit of the suction unit of an outdoor unit chambers and the most contiguous outdoor unit chambers was adjacent, above-mentioned effect can be more remarkable.
In order to omit a special-purpose air guider that is used to control discharge directions is installed, the direction in the hole of leafy chip cooling fan must be towards the upper surface unit and the lower surface unit of off-premises station cabinet.But in this case, the hole is not towards suction area but vertical with suction area.
In the above-described embodiments, employed centrifugal cooling fan is leafy chip cooling fan.But,, also can be suitable for same principle if employed centrifugal cooling fan is a turbofan.That is, by in adjacent off-premises station, install the turbofan hole up/turbofan down, and keep the direction of rotation of turbofan opposite each other, also can make off-air to direction discharge away from the most contiguous off-premises station.
For convenience's sake, with the hole up/under centrifugal cooling fan be example.In order to embody the technological thought of claim of the present invention, by using a fan hole towards the centrifugal cooling fan of unit, two sides and the air-deflector of suitable shape is installed, off-air is discharged to the direction away from the most contiguous off-premises station.
In addition,, for example replace centrifugal cooling fan, and the air-deflector that suitable shape is installed can make also the off-air after the heat exchange discharge to the direction away from the most contiguous off-premises station with aerofoil fan by difform fan.In these cases, air-deflector is installed between cooling fan and the louver frame, can't see so outside, can play effect attractive in appearance.
As previously discussed, the structure of off-premises station of the present invention can reduce to be equipped with a plurality of before on the apartment building of suctions/discharge formula air-conditioner outdoor units the heat exchanger effectiveness between the adjacent off-premises station lose.Therefore, can reduce to be installed in phase mutual interference between the off-premises station in each room of tall and big apartment building or commercial building.
Though preferred embodiment be illustrated of the present invention, the present invention is not limited to these preferred embodiment, and in the thought and scope of claim of the present invention, those skilled in the art can make amendment and improves the present invention.
