High latent circuit with heat recovery device

An improved conditioned air system of the type having an indoor coil, an outdoor coil, a compressor and an expansion device, wherein the improvement comprises:

• a heat recovery device having a cooling portion and a heating portion operatively interconnected;
• a blower for taking in return air from a space and passing it through said heat recovery device to be conditioned prior to being discharged outside;
• a blower for bringing in substantially 100% outside air, passing it through said heat recovery device to be conditioned and then passing it through the indoor coil for further conditioning;
• and
• a subcooler downstream of said indoor coil such that the air passing from the indoor coil passes through the subcooler prior to its entering the space and including an evaporative cooler disposed upstream from said heat recovery device such that the return air flows through said evaporative cooler prior to its being passed through said heat recovery device.
