Abstract: An electrical grounding clip for grounding the outer casing of a room air conditioner to the base pan of the chassis in a manner to assure positive grounding contact upon the chassis being slidably inserted within the casing. The clip includes a U-shaped body portion forming two leaf portions normally oriented at an outwardly diverging angle, the casing engaging leaf being formed with a pair of spring legs and a cooperating lanced portion for engaging a pair of cooperating openings in the lower wall of the casing. The chassis engaging leaf portion includes an upwardly extending central cone having a sawtooth-like edge for resilient biased grounding connection with the chassis base pan.

Abstract: An air conditioning unit in which a housing is provided having side walls adapted to extend within an opening formed in an exterior wall of a room to be cooled. Air inlet and outlet means are associated with the front wall and rear walls of the housing to circulate room air and ambient air through the unit. A condenser heat exchanger and an evaporator heat exchanger are disposed in the housing in proximity to its rear wall and front wall, respectively, and extend at an angle relative to the latter walls. Ambient air is circulated into the inlet associated with the rear wall, across the condenser heat exchanger and out the outlet associated with the rear wall, and room air is circulated through the inlet associated with the front wall, across the evaporator heat exchanger and out the outlet associated with the front wall.

Abstract: The present invention relates to a room air conditioning unit and is more specifically directed to the airflow control mechanism for adjusting the airflow through a vent generally associated with such units for permitting a flow of air between the air conditioned space and the outdoor air.

Abstract: A room air conditioner wall sleeve and subbase assembly for a 277 voltage range permanently wired installation located in a room wall opening. The subbase casing has a pair of side-by-side removable covered openings providing access to separate enclosures, one of which encases an electrical outlet receptacle for the power cord plug of the air conditioner chassis while the other enclosure encases the permanent field or "hard" wiring connection for the installation. The access cover for the power cord receptacle enclosure has a self-contained outwardly formed shield, including an upwardly extending portion that defines, with the sleeve front flange and sleeve front assembly, a convenient code approved electrical duct passage for encasing the power cord.

Abstract: An economizer kit for attachment to the outside of a return air duct of air conditioning systems. The kit comprises what is termed a housing having end walls and side walls which define a conduit open at both ends. At one end of the conduit, there is a by-pass passage formed by two chambers that under certain operating conditions are in open communication with each other but under other operating conditions, are separated by a movable damper, one of these chambers is an inlet chamber for air from the return air duct of the air conditioning system, while the other chamber is an outlet chamber for air returning to the return air duct. At the opposite end, the conduit has a partition extending longitudinally part-way in the conduit thus deviding the conduit into an outlet passage for air from the inlet chamber and an inlet passage adapted to communicate with the outlet chamber. The outlet passage discharges to ambient atmosphere and the inlet passage receives ambient atmospheric air.

Abstract: A blower in which on a suction side of a cross flow fan having a vortex stabilizing plate and a back guider is provided a flow dividing guider, which is different from the back guider, for changing the flowing direction of a portion of the air flow. The blower in accordance with the present invention is suitable to be used as a blower for a cooling apparatus, a heating apparatus, a ventilator, and the like, and has a wide variety of applications other than mentioned above.

Abstract: A simple climate control device is disclosed which can independently, or jointly, to the degree desired, ventilate and/or dehumidify and/or cool a dwelling. The device provides a way of supplying fresh outside air to a building or other space at a preferred humidity level while optionally cooling the inside air, and as desired dehumidifying the inside air to maintain the inside environment at a preferred temperature and at a preferred relative humidity, with gradual displacement of stale air by fresh air.
