Abstract: An air handler system comprising a cabinet housing a blower unit and a heat exchange unit. The blower unit and the heat exchange unit are located in a substantially same lateral dimension in the cabinet. The blower unit and the heat exchange unit are separated by a distance that provides for a substantially uniform flow of air through a vertically-orientated plane of the heat exchange unit when the blower unit is in operation.

Abstract: A structural plate for an air handler system. The system comprises a single sheet having at least two of the following structural elements: a) an air baffle for a heat exchanger; b) a stabilizer bracket attachable to an air handler cabinet; c) an air handler control box bracket; or d) a filter holder.

Abstract: A refrigeration connection tube. The tube comprises a flexible section of tubing that includes a ribbing. The ribbing circumscribes the flexible section of tubing in a direction that is substantially perpendicular to a long axis of the flexible section of tubing. The ribbing traverses an entire thickness of the flexible section of tubing.

Abstract: Air conditioning apparatus is provided in which an air blower and an electric heater assembly are located in a common housing with the heater assembly projecting into the housing from a wall thereof in transverse relationship to the blower. This configuration eliminates the need for a dedicated space for the electric heater downstream of the blower housing, which reduces the size of the apparatus. The wall of the housing includes an opening through which the heater assembly is insertable into the housing. The heater assembly includes a mounting plate to close off the wall opening and to removably mount the heater assembly with the housing. The heater assembly preferably further includes an open coil electric heater, with a major dimension of the heater being oriented generally parallel to the direction of air flow in the blower housing.
