Air conditioning unit

Abstract

An AC unit with a lifting mechanism to lift or lower the AC unit relative to an insulated duct installed at a windowsill next to an insulated and relatively thick grill is disclosed. The AC unit includes multiple air conditioning components, a thermal shield integrated inside a housing, a skirt, and the lifting mechanism. A base portion of the housing is coupled to the top frame of the lifting mechanism. The lifting mechanism includes a pair of scissors pivoted to the bottom frame and the top frame. A telescopic skirt is arranged inside the bottom of the housing. The lifting mechanism ensures inlet and exhaust ports of the AC unit are aligned in a colinear fashion with respect to the duct so that the AC unit cools the condenser faster without wastage of effective air coming out of the air conditioning that would otherwise be used for cooling the room.
