Description
- The present invention relates to the field of building structures. More particularly, the invention relates to a building structure for garage mounted air conditioning apparatus.
- Many air conditioning systems are of the split type that comprises an outdoor unit that includes a compressor, condenser and fan for drawing ambient air across the condenser, an indoor unit including an evaporator and a fan for drawing the interior air across the evaporator so that the conditioned air will be discharged to the space to be conditioned, and a conduit through which refrigerant flows in a closed cooling or heating cycle between the outdoor and indoor units.
- However, the outdoor unit housed in a large-sized casing is unsightly and also adds noise pollution. These deficiencies are exacerbated in an urban environment or in a multi-family dwelling where a high population density results in a proliferation of outdoor units.
- It is an object of the present invention to provide a building structure that facilitates the installation of a split air conditioning system that does not detract from the appearance of the building, yet that provides a superior air conditioning effect.
- Other objects and advantages of the invention will become apparent as the description proceeds.
- A building structure for garage mounted air conditioning apparatus comprises a garage having an interior defined by a plurality of walls including at least one exterior wall on which a concealed condensing unit (CCU) of the air conditioning apparatus is mountable, a ceiling, and a garage door of an overhead type which is engageably displaceable along a track having an inverted L-shape, wherein said at least one exterior wall is formed with at least one through-hole opening in a headroom between a horizontal section of the track and the garage ceiling which is in fluid communication with the CCU.
- The building structure is preferably further configured with one or more mounting elements for mounting the CCU onto one of the exterior garage walls, wherein the CCU has a casing for enclosing CCU components including a freestanding compressor and a condenser coil, said one or more mounting elements configured to mount the casing having a maximum height approximately equal to the height of the compressor and less than the height of the headroom without interfering with the horizontal section of the track or with the garage door when set to an opened position and in engagement with the horizontal section of the track.
- In one aspect, the at least one through-hole opening is an opening through which CCU exhaust air is exhausted to the atmosphere and the one or more mounting elements is a frame member surrounding the opening through which CCU exhaust air is exhausted to the atmosphere, wherein said frame member is configured in such a way that an exhaust opening of the CCU is aligned with the opening through which CCU exhaust air is exhausted to the atmosphere.
- In one aspect, the at least one through-hole opening is an opening through which intake air from the atmosphere is introduced to the CCU and the one or more mounting elements is a frame member surrounding the opening through which intake air is introduced, wherein said frame member is configured in such a way that an intake opening of the CCU is aligned with the opening through which intake air is introduced.
- In one aspect, a second exterior garage wall spaced from a first exterior garage wall on which the CCU is mounted is formed with a duct opening within which a duct extending to the CCU is fixed. The duct opening is formed in a headroom between a horizontal section of the track and the garage ceiling.
- In one aspect, the building structure is additionally configured with at least one penetration formed in the garage ceiling, a corresponding conduit through which flows a refrigerant adapted to condition at least one interior room of the building extending upwardly through said at least one penetration to an indoor unit of the air conditioning apparatus.
- In one aspect, the building structure is additionally configured with a drain element through which condensate produced by the CCU is dischargeable.

FIG. 8 is a schematic top view of a portion of a garage, showing a building structure according to another embodiment; and -
FIG. 9 is a schematic top view of a portion of a garage, showing a building structure according to another embodiment. - A building structure facilitates the mounting of the outdoor unit of a split-type air conditioning system within a residential garage adapted to protect a parked car from precipitation, while concealing the outdoor unit and improving the appearance of the building.
- The type of residential garage that is used is one that is attached to a house, or that is spaced by a small distance from a house. An attached garage may be equipped with a locked garage door and with an entry door that leads to the interior of the house, for the comfort of the passengers of the car.
- By virtue of the proximity of the garage to the house, the wall space of the garage is generally used as convenient storage space for items not needed within the house such as outdoor tools and a bike rack or for infrequently used items such as a ladder and lumber. At times bumpers, often in the form of old tires, are mounted on a garage wall to absorb the impact caused by an improperly parked car, and reduce the available wall space. Accordingly, a residential garage is generally unsuitable for the installation therewithin of a conventional outdoor unit having a height of at least approximately 40 inches due to the depletion of valuable storage space.
- The building structure helps to improve the appearance of the house without reducing the available storage space within a garage by providing one or more mounting elements for the outdoor unit of a split-type air conditioning system within the normally unused clearance of a garage wall above a track along which a garage door is engageably displaced when being moved from a closed position to an open position, or vice versa.
- As shown in
FIG. 1 , aresidential garage 10 is generally equipped with two laterally spaced tracks 5 (only one being shown) of inverted L-shape.Overhead garage door 3, made of a plurality of articulated panels and normally set to the illustrated closed position, is guided along the twotracks 5 by a set of rollers. Eachtrack 5 has avertical section 2 rising to about a height of eight inches below the door height, ahorizontal section 4 supporting the majority ofdoor 3 when set to an opened position, and acurved section 7 extending betweenvertical section 2 andhorizontal section 4. The terminal end ofhorizontal section 4 is supported by avertical hanger 9 connected to theceiling 13 ofgarage 10. Acenter rail 14 for guiding an arm connected togarage door 3 and anelectric door operator 17, which may be electronically controlled, are also provided. - Since the
standard headroom 11, or clearance betweenhorizontal section 4 andceiling 13, is only 14.25 inches for acurved section 7 having a radius of 15 inches, this clearance is invariably unused for storage space due to its small size, inaccessibility and the need for mounting a bracket or the like for supporting the storage apparatus togarage wall 19, thereby further reducing the available storage space. Also, a conventional outdoor unit having a height of at least approximately 40 inches cannot be suitably mounted withinheadroom 11. - The use of a concealed condensing unit (CCU) 20 will obviate the geometric constraints related to mounting an outside unit within
headroom 11. - As schematically illustrated in
FIG. 2 , CCU 20A, generally ducted, comprisescompressor 21,condenser coil 24, which may be of a multidirectional shape, through which flows pressurized refrigerant received from compressor, one or morecentrifugal fans 25, and PCB 26 for controlling the operation ofcompressor 21 and eachfan 25. Air is drawn intointake opening 28, which may be protected by a grille, by eachcentrifugal fan 25 and is forced to flow, in accordance with the configuration ofcondenser coil 24 and theCCU casing 27, across the width ofcondenser coil 24 and along the entire length thereof in order to condense the refrigerant. The exhaust heat transferred from the refrigerant to the air flow exitingcondenser coil 24 is drawn through eachcentrifugal fan 25 and discharged through each exhaust opening 29. - The discharged exhaust air is hot when the CCU is operating in a cooling mode and is cold when the CCU is operating in a heating mode.
- As opposed to the conventional large-dimensioned outdoor unit that employs an axial fan to induce air flow axially along the vertically oriented shaft of the fan blades, CCU 20A employs the one or more
centrifugal fans 25 to induce radial air flow, generally 90 degrees relative to the horizontally oriented shaft driving the fan wheel on which are mounted backward-curved blades. The outer diameter of each centrifugal fan housing from which the radial air flow exits through acorresponding exhaust opening 29 under the influence of centrifugal force is therefore able to be significantly smaller than the outer diameter of an axial fan, resulting in a relatively small CCU height of approximately 11 inches that can be mounted in the headroom above a garage door track, while taking into account the thickness of the garage door, without being subjected to overheating. - Alternatively, a CCU 20B schematically illustrated in
FIG. 3 may be used. CCU 20B having a similar configuration as CCU 20A ofFIG. 2 may employ a plurality ofaxial fans 32 provided with a horizontally oriented shaft, allowing the height of the axial fans to be less than the freestandingcompressor 21 and the height ofCCU casing 37 to be approximately 11 inches. - Reference is now made to
FIG. 4 , which schematically illustratesbuilding structure 40, according to one embodiment of the present invention.Building structure 40 is configured with anopening 49 formed in theheadroom region 11 ofgarage wall 19, through which the CCU exhaust air is discharged to the surroundings externally togarage wall 19. Aframe element 42 surroundingopening 49, to which the CCU is mounted, is fixed withingarage wall 19. - According to this arrangement, the exhaust air discharged from the CCU is directed outwardly from the garage interior, without being bothersome to any person located within the garage interior by virtue of the elevated height of
headroom region 11. Intake air may be derived from the garage interior and received by the intake opening of the CCU. The exhaust air discharged from the exhaust opening of the CCU is thus exhausted via opening 49 to the atmosphere. - Although the standard sideroom, or space available between a
track 5 andgarage wall 19 is 4.5 inches, while referring also toFIG. 1 , a CCU mounted within the headroom ofgarage wall 19 will protrude laterally into the space between, and above, the twotracks 5 without interfering with a schematically illustratedgarage door 3′ set to the opened position. -
Building structure 40 is also configured with one ormore penetrations 57 to accommodate the extension therethrough of a corresponding number of conduits through which the refrigerant circulates between the CCU and the indoor unit and of electrical wires for operating the air conditioning system. Apenetration 57 is shown to be formed ingarage ceiling 13 when a habitable region of the house is constructed therebove, although it will be appreciated that the penetrations can be formed in any suitable garage surface, such as in a wall adjoining an entry door leading to the interior of the house. - As shown in
FIG. 9 , abuilding structure 45 may include an air discharge fitting 47 extending from the exhaust opening ofCCU 30 may be fixed toair opening 49 formed withingarage wall 19.Air discharge fitting 47 may be coupled, releasably or fixedly, to the periphery of air opening 49 by a corresponding bracket, or other mounting means 46 well known to those skilled in the art. The heated exhaust air flows through air discharge fitting 47 to air opening 49, from which it is exhausted to the atmosphere, thus preventing overheating of the garage interior. Alternatively, fitting 47 may be an air intake channel extending fromair opening 49 to which it is coupled to the air intake opening ofCCU 30. - A layout of
air conditioning system 55 withinhouse 59 is illustrated inFIG. 5 .Air conditioning system 55 comprises garage-mountedCCU 30, indoor unit 62, and at least oneconduit 61, e.g. horizontally and vertically extending segments of a copper conduit, through which the refrigerant circulates betweenCCU 30 and indoor unit 62.CCU 30 is shown to be spaced fromgarage ceiling 13. Whenhouse 59 is a multi-story house and indoor unit 62 is mounted in attic space 68, although it will be appreciated that indoor unit 62 may be mounted in any other suitable interior space, buildingstructure 40 is also configured with one or more penetrations 66 formed in theceiling 67 interfacing asecond floor 64, for example, with attic space 68, through which eachconduit 61 extends, in addition to extending throughpenetration 57 throughgarage ceiling 13. Indoor unit 62 may operate in conjunction with a central air conditioning system, or, alternatively, may be an independent unit positioned in a specific room withinhouse 59. - When indoor unit 62 is a heat exchanger operable in a cooling mode, cooled liquid refrigerant under high pressure exits the condenser coil of
CCU 30 and flows upwardly to an expansion valve of indoor unit 62, which restricts the flow of the refrigerant and causes its pressure to be reduced. The low-pressure liquid refrigerant flows to the evaporator, across which interior air from an interior room of buildingstructure 40 to be conditioned is drawn by the fan of indoor unit 62, and absorbs heat from the interior air. The conditioned air is discharged to the interior room, and the refrigerant is changed to a gaseous state. The heated low-pressure gaseous refrigerant then flows downwardly to the compressor ofCCU 30 to repeat the cycle. - Indoor unit 62 may also be configured as an air handling unit (AHU) comprising a mixing box within which is blended air from a return duct exiting the room to be conditioned and air from a supply duct, and a blower for forcing the blended air to flow across an evaporator containing the refrigerant, or as a fan coil unit (FCU) provided with a coil through which the refrigerant flows and a fan to condition a room without being connecting to ductwork.
- Building
structure 40 may also be configured with adrain element 69 through which condensate produced, for example in a heating mode, is dischargeable.Drain element 69 may be provided in proximity to the condenser coil, or to any other region ofCCU 30. -
Drain element 69 may also be a pipe that is installed at a lowest point ofgarage 10, which may be located directly belowCCU 30, and that slopes underground towards the street. The collected condensate may be gravitationally drained, for example to the sewerage system of the building, or may be delivered by a pump to a drain system. Alternatively,drain element 69 may be any other drain element well known to those skilled in the art. - For the cooling mode, a drain element, e.g. elongated, may be fixated within a vertical drain pipe extending through
penetrations 57 and 66, to receive condensate generated by indoor unit 62. Such a drain element is configured in such a way to discharge the condensate while bypassingCCU 30. - The
casing 31 ofCCU 30, which facilitates efficient operation of the air conditioning system in conjunction with building structure 40 (FIG. 5 ), is illustrated inFIG. 6 .Casing 31 has a rectilinear configuration, although other configurations are also possible. Front and rearservice access panels 33 are provided to ensure thatintake opening 38 andexhaust opening 39 will be substantially mutually parallel.CCU 30 may be of the same height ofCCU 20A ofFIG. 2 , and comprises the same air conditioning components asCCU 20A, while the internal arrangement of the air conditioning components is different to accommodate the substantially mutually parallel relation ofintake opening 38 andexhaust opening 39. The substantially mutually parallel relation ofintake opening 38 andexhaust opening 39 ensures that the exhaust air will not infiltrate into the intake air, to prevent a reduction in the thermodynamic efficiency of the cycle due to the increased temperature of the intake air, even if externally mounted ducts were not employed. - In another embodiment, a
CCU 70 shown inFIG. 7 may be employed.Casing 71 ofCCU 70 has a rectilinear configuration, although other configurations are also possible.Access panels intake opening 78 andexhaust opening 79 will be substantially mutually perpendicular.CCU 70 may be of the same height ofCCU 20A ofFIG. 2 , and comprises the same air conditioning components asCCU 20A, while the internal arrangement of the air conditioning components is different to accommodate the substantially mutually perpendicular relation ofintake opening 78 andexhaust opening 79. The substantially mutually perpendicular relation ofintake opening 78 andexhaust opening 79 ensures that the exhaust air will not infiltrate into the intake air even if externally mounted ducts are not employed. - Building
structure 80 illustrated inFIG. 8 includes aduct opening 89 formed ingarage wall 86 spaced from, such as being opposite to,garage wall 19 on which is mountedCCU 30. The garage wall which is formed withduct opening 89 is dependent upon the CCU configuration, as shown inFIG. 6 orFIG. 7 . Anair discharge duct 82 extending from the exhaust opening ofCCU 30 may be fixed toduct opening 89.Air discharge duct 82 may be coupled, releasably or fixedly, to the periphery ofduct opening 89 by a corresponding bracket, or other mounting means 88 well known to those skilled in the art. The heated exhaust air flows throughair discharge duct 82 toduct opening 89, from which it is exhausted to the atmosphere, thus preventing overheating of the garage interior. Alternatively,duct 82 may be an air intake duct extending fromduct opening 89 to which it is coupled to the air intake opening ofCCU 30, and the exhaust air is discharged via the exhaust opening ofCCU 30 and opening 49 (FIG. 4 ). - While some embodiments of the invention have been described by way of illustration, it will be apparent that the invention can be carried out with many modifications, variations and adaptations, and with the use of numerous equivalents or alternative solutions that are within the scope of persons skilled in the art, without exceeding the scope of the claims.
