ABSTRACT:
An air conditioning apparatus for both heating and cooling an enclosed space. The apparatus employs a vapor compression refrigeration system in which the flow of refrigerant through the inside and outside heat exchangers is the same in both cooling and heating modes. The alignment of an arrangement of dampers determine whether air from the space passes through the evaporator section of the apparatus (during operation in the cooling mode) or through the condenser section (during operation in the heating mode). The same damper arrangement reconfigures the flow of outside air from the condenser section to the evaporator section on a shift from cooling to heating mode operation. The apparatus is entirely contained within a single enclosure intended for installation in an exterior wall of the structure that it serves. The evaporator section is located above the condenser section in the enclosure so that the area occupied by the apparatus is minimized and also so that water condensate that forms on the evaporator can drain by gravity to the condenser where it can be re-evaporated and carried out of the enclosure by the air passing through the condenser. The apparatus has operating modes that accelerate the removal of frost that may form on the evaporator during heating mode operation and that supply outside air and exhaust inside air from the enclosed space. The compressor and blowers of the apparatus may be of the type that can operate at more than one speed.
