Abstract:
1. There is firstly disclosed herein an air conditioning apparatus including; a first and a second air inlet; a heat exchanger having a first air path and a second air path, the first air path communicating with said first air inlet so as to receive air therefrom, said second air path communicating with said second air inlet so as to receive air therefrom, the air path being adjacently located so as to provide for heat transfer between air passing along the paths; a first heat exchanger coil through which a refrigerant flows to cool or heat the first coil, said first coil being in communication with said second air path so as to receive air therefrom to cool or heat air passing through the first coil; and a second heat exchanger coil through which the refrigerant passes to cool or heat the second coil, the second coil being in communication with the first air path so as to receive air therefrom so that air passing through the second coil is heated or cooled thereby; and wherein the first and second coils are part of a refrigeration cycle such that when said first coil is heating air, said second coil is cooling air, while when said first coil is cooling air said second coil is heating air.
