ABSTRACT:
An air conditioning unit having a power pack which includes an internal combustion engine coupled to a refrigerant compressor on a metallic support tray, with said air conditioning unit being suitable for mounting on the roof of a building via support curbing, notwithstanding the noise and vibration produced by the internal combustion engine. The air conditioning unit includes a metallic main frame, to which a metallic power pack support frame is fixed. The power pack support frame includes members which are continuously supported by the main frame via a low frequency damping material, such as cork, and members which extend between the supported members, but which are otherwise unsupported, to enable the unsupported members to function as leaf springs. The support tray of the power pack is mounted to the unsupported members of the power pack support frame via a plurality of isolation mounts.
