  • Patent number: 5810322
    Abstract: Apparatus (20) for mounting the horizontal compressor (10) of a vapor compression air conditioner to a foundation includes an L-shaped bracket (21) at each compressor end, each bracket having a horizontal leg (21H) adapted for attachment to mounting lugs (11) which extend laterally outwardly from the compressor casing. Each bracket is sized and otherwise configured so that its vertical leg (21V) extends upwardly from the horizontal leg along the outside of an end (102 or 103) of the compressor casing (101) to a point above the drive shaft axis of rotation (A.sub.R) of the compressor motor. A pin (22) is secured to and extends outwardly from the vertical leg of the bracket. The longitudinal axis of each pin is coincident with the driveshaft axis of rotation. Each pin extends into a pin socket (25) in a respective mounting support (24) which is securely fastened to a foundation (30) such as the base pan of an air conditioner.

  • Patent number: 5337580
    Abstract: A low profile room air conditioner. The low profile is achieved in part by the arrangement of components in its outside section. The fan that moves air through the outside section is of the axial flow type mounted so that its axis of rotation is substantially perpendicular to the base of the enclosure and so that the fan draws air into the outside section through the top of the enclosure. Air discharges from the outside section through an air discharge on a side of the enclosure. Louvers at the air discharge direct the air exiting the enclosure away from the air inlet. A slinger directs droplets of condensate drained from the inside refrigerant-to-air heat exchanger into the air flowing through the outside section. The air carries the condensate on to the outside refrigerant-to-air heat exchanger where it evaporates. The air flow carries the resultant water vapor out of the outside section.
