収納した圧縮機室がそれぞれ平面的に別々に配置された
構造が一般的であった。また、インバータ等の制御機器
を収納するインバータ室についても別個に形成されてい
た。Conventional air conditioners are mounted on the roof of a vehicle, as described in Utility Model Application Publication No. 59-120620, and include an outdoor equipment room that houses a J1 compressor and an outdoor fan, an evaporator, and an indoor fan. The common structure was that an indoor equipment room containing a large number of compressors and a compressor room containing multiple compressors were arranged separately on a plane. Furthermore, an inverter chamber for housing control equipment such as an inverter was also formed separately.
上記従来技術は車両の屋根上に搭載する空調装置のコン
パクト化、薄形化、および軽量化について配慮がなされ
ておらず、特に既存車両の冷房化改造に際して問題があ
った。The above-mentioned conventional technology does not give consideration to making the air conditioner mounted on the roof of the vehicle more compact, thinner, and lighter, and this poses a problem particularly when retrofitting an existing vehicle to provide cooling.
すなわち、従来技術のように室外機器室、室内機器室と
は別に独立した圧縮機室やインバータ室を設けることに
より、空調装置の寸法が大ｈ＜なるので、重量的にも大
き畷なり、車両の屋根上に搭載するためには車体の屋根
および側壁の剛性を増強する必要がある。In other words, by providing an independent compressor room and inverter room separately from the outdoor equipment room and the indoor equipment room as in the conventional technology, the size of the air conditioner becomes large h<, which increases the weight. In order to install it on the roof of a car, it is necessary to increase the rigidity of the roof and side walls of the car body.
特に既存車両に空調装置を追設する場合は、この空調装
置の、重量が大きいと屋根の補強作業が大がかりとなり
、追設工事（冷房化改造工事）が高価になるという問題
があった。Particularly when adding an air conditioner to an existing vehicle, there is a problem in that if the air conditioner is heavy, the roof reinforcement work will be extensive and the additional work (cooling modification work) will be expensive.
また圧縮機室やインバータ室は高さが大きくなるため、
それらを全部車両の屋根上に搭載しようとすると車両か
ら突出する寸法が大きくなり、車種によっては車両限界
なオーバするため、既存車両に搭載できなくなったり、
新車の場合は車体を小形にしなければならな畷なるとい
う問題があった。Also, since the height of the compressor room and inverter room is large,
If you try to mount all of them on the roof of a vehicle, the dimensions that protrude from the vehicle will become large, and depending on the vehicle model, this may exceed the vehicle limit, making it impossible to mount them on existing vehicles.
In the case of new cars, there was a problem that the car body had to be made smaller.
なお、Ｍ配車両限界は保安上、車両の付属機器を含めた
許容断面寸法のことで、路線車種毎に決められている。For safety reasons, the M vehicle distribution limit refers to the permissible cross-sectional dimensions of the vehicle, including its accessories, and is determined for each route vehicle type.
本発明の目的は、車両の屋根を大輪に輪強することなく
搭載可能な、コンパクトで、＠量化に適した車両用空ｆ
ａＩＩ装置を提供することにある。The purpose of the present invention is to provide a compact vehicle air spacer that can be mounted on the roof of a vehicle without adding large wheels, and is suitable for @quantification.
An object of the present invention is to provide an aII device.
上記目的は、圧縮機を室外機器室の中の、凝縮器と室外
ファンの間の空間に設置し、インバータを室内機器室の
中（こ設置することによって、達成される。The above object is achieved by installing the compressor in the space between the condenser and the outdoor fan in the outdoor equipment room, and installing the inverter in the indoor equipment room.
すなわち、空調装置を室外機器室と室内機器室により構
成し、圧縮機を収納できる圧縮機室を室外機器室の中の
空間に設けるとともに、室内機器室のリターン口にイン
バータを設置することによりて達成される。In other words, the air conditioner is configured with an outdoor equipment room and an indoor equipment room, and the compressor room that can accommodate the compressor is provided in the space inside the outdoor equipment room, and an inverter is installed at the return port of the indoor equipment room. achieved.
本発明の空調装置は室外機器室と室内機器室によって構
成され、複数台の圧縮機を収納できる圧縮機室が室外機
器室の中に、そして、インバータは室内機器室のリター
ン口内に設けられている。The air conditioner of the present invention is composed of an outdoor equipment room and an indoor equipment room, the compressor room that can accommodate a plurality of compressors is provided in the outdoor equipment room, and the inverter is provided in the return port of the indoor equipment room. There is.
それによって空調装置の枠組寸法が小さくなるので、軽
量化される。This reduces the frame size of the air conditioner, thereby reducing its weight.
また、室外機器室の中に設置された圧縮機は室外ファン
によりて冷却されるので放熱の点で心配がない。Furthermore, since the compressor installed in the outdoor equipment room is cooled by an outdoor fan, there is no need to worry about heat radiation.
