Abstract: A portable, monoblock air conditioner including an evaporator and a condenser, a drain pan for collecting water condensate that has condensed from the evaporator, a hot air exhaust hose for evacuating warm air to an outside environment, a water tube in fluid communication with the drain pan, the water tube running through the hot air exhaust hose, and an atomizer at a distal end of the water tube adapted for atomizing water exiting the water tube which exits together with hot air exiting the hot air exhaust hose.

Abstract: A portable, monoblock air conditioner including an evaporator positioned over a condenser, the condenser including heat transfer fins, and a partition positioned between the evaporator and the condenser, the partition formed with openings arranged for condensate to flow from the evaporator over the heat transfer fins of the condenser, wherein there are more than one of the openings over each heat transfer fin. Adjacent rows of openings over the heat transfer fins may be staggered with respect to each other. The heat transfer fins may have a hydrophilic coating.

Abstract: A louver assembly particularly useful for air-conditioning units and other like appliances comprises a frame defining an opening; a first group of slats extending along one coordinate axis mounted to the frame within the opening and pivotable about that axis; a second group of slats extending along a second coordinate axis mounted on the first group of slats within the opening and pivotable about that axis; and a manipulatable knob coupled to both groups of slats such that moving the knob in a direction parallel to the second coordinate axis pivots the first group of slats about the first coordinate axis, and rotating the knob about the second coordinate axis pivots the second group of slats about the second coordinate axis.

Abstract: Fluid filter apparatus including a body member defining a fluid inlet, a fluid outlet and a plurality of debris outlet apertures, a filter seated in the body member, and a cover member including a sleeve portion and an annular skirting mounted about the body member and arranged to assume a first orientation wherein the sleeve member is in sealing engagement with the debris outlet apertures and a second orientation wherein the annular skirting lies in adjacent non-sealing relationship with the debris outlet apertures whereby water and debris exiting therefrom impinge on the skirting for being deflected thereby.

Abstract: A heat transfer system is disclosed in which heat is transferrable to a first primary user by means of a two-coil heat exchanger acting as a condenser which is in the high pressure path, while at the same time another two-coil heat exchanger used as a condenser is used to provide cooling to a record primary user. The system also includes a fan type heat exchanger, which acts as the condenser, when the first primary user does not need heating energy. The system is also operable to heat the second primary user whose heat exchanger acts as a condenser, connectible in series with the heat exchanger of the first primary user.
