ABSTRACT:
The invention is of a new design for a room air conditioner. An air conditioner according to the present design will emit a substantially lower operating noise level than units of comparable cooling capacity and energy consumption. Additionally, the present design prescribes a coil design which requires approximately one-third less aluminum and copper than similarly performing room air conditioner units. The benefits of the present design arise from its reliance on a single row, wrap-around coil design which is used in conjunction with a tangential blower assembly. The single row evaporator coil of the present invention inherently produces less "wind noise" than multiple row coils. The positioning of the blower relative to the evaporator coil (the blower is enveloped by the coil in the preferred embodiment) and the positioning of the evaporator coil relative to the inner wall of the unit (which separates interior from exterior space) causes room air to flow into the space defined by the wrap-around evaporator coil from all directions, including the space adjacent to the inner wall, which air flow reduces the temperature gradient across the inner wall and reduces chassis insulation requirements.
