A support for mounting an air conditioner for operative disposition in a window, while being free of any supports external to the window and of any metallic fastener contact with the window, includes elongated top and bottom members of lightweight construction, sized and shaped to extend parallel to an interior window sill of the window, with opposite ends of the top member extending beyond vertical side jambs of the window. First and second transverse members of polymeric molded construction extend between the top and bottom members to define a receptacle sized and shaped to slidably receive the air conditioner therein and to interferingly engage an elongated flange extending along an upper surface of the air conditioner. The top and/or bottom members include hand-holds and the top member is adjustable to accommodate windows of various sizes.

A window air conditioner includes a casing including a cabinet. The cabinet includes a receiving groove formed at an outer peripheral wall of the cabinet. The receiving groove is recessed downwards to separate the cabinet into an indoor part and an outdoor part. The window air conditioner further includes an indoor heat exchanger and an indoor fan arranged in the indoor part, and an outdoor heat exchanger and a compressor arranged in the outdoor part.

An air conditioning and heat pump tower includes a main casing, a plurality of connecting pipes, a compressor, a front heat exchanger, a rear heat exchanger, a fan unit, and an energy efficient arrangement. The energy efficient arrangement includes a first pre-heating heat exchanger supported in a front compartment of the main casing, and positioned between an outdoor air intake opening and an outdoor heat exchanging portion of the front heat exchanger. The air conditioning and heat pump tower may be operated between an air conditioning mode for absorbing heat from the indoor space, and a heat pump mode for producing heat to the indoor space. A predetermined amount of ambient air may be drawn through the outdoor air intake opening and may be pre-heated by the energy efficient arrangement before delivering to the indoor space.
