Abstract: An air conditioner is provided which is mounted on the rooftop of a recreational vehicle to provide cooling of an interior space within the vehicle. The air conditioner has a single motor that mounts both a centrifugal fan and an axial fan for rotation about a vertical axis. The centrifugal fan is positioned within an evaporator compartment that contains an evaporator for providing cooling of an air stream drawn therethrough.

Abstract: A cool air circulation apparatus in a refrigerator provides an upper curved lip extended from a front face of a lower shelf in a refrigerating chamber, by which cool air contacting with ambient air is discharged outside of the refrigerator and only the cool air adjacent to the refrigerating chamber flows into the refrigerating chamber.

As a result, a constant temperature in the refrigerating chamber is maintained at all times, thereby being capable of maintaining freshness of a stored foods for a long time.

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.
