Claim:
A heating and air conditioning apparatus small-duct, high-velocity comprising: a single enclosure having a plurality of sidewalls, a bottom wall, and a top wall that are all interconnected to enclose an interior volume of the enclosure and to enable the enclosure to be transported as a single unit; a refrigerant fluid compressor in the enclosure interior volume; a condenser coil in the enclosure interior volume and in fluid communication with the compressor; an expansion valve in the enclosure interior volume and in fluid communication with the condenser coil; an evaporator coil in the enclosure interior volume and in fluid communication with the expansion valve and the compressor; a hot water coil in the enclosure interior volume said hot water coil being operably connectable to a separate hot water source; a first input air opening in the enclosure and a first output air opening in the enclosure; an evaporator fan in the enclosure interior volume, the evaporator fan being positioned in the enclosure interior volume to draw air in a first flow path that enters the enclosure interior volume through the first input air opening and then passes through the evaporator coil, and then passes through the hot water coil, and then passes through the evaporator fan and then exits the enclosure interior volume through the first air outlet opening; a second air input opening in the enclosure and a second air output opening in the enclosure; and, a condenser fan in the enclosure interior volume, the condenser fan being positioned in the enclosure interior volume to draw air in a second flow path that enters the enclosure interior volume through the second input air opening and then passes through the condenser coil, and then passes through the condenser fan and then exits the enclosure interior volume through the second air outlet opening.
