Abstract
A heating and air conditioning apparatus has an enclosure that defines an interior volume containing a compressor, a condenser coil, an expansion valve, an evaporator coil, a hot water coil, an evaporator fan, and a condenser fan. The compressor, the condenser coil, the expansion valve, and the evaporator coil are in communication with each other. The enclosure also has first and second input air openings and first and second output air openings. The evaporator fan draws air through the first input air opening and then through the evaporator coil and the hot water coil, and thereafter forces such air out of the enclosure through the first air outlet opening. The condenser fan draws air through the second input air opening and then through the condenser coil, and thereafter forces such air out of the enclosure through the second air outlet opening.
