Abstract
The invention is an air conditioning unitconsisting of a housinghaving at least one air inletfor receiving air to be conditioned and at least one outletfor discharging conditioned air, at least one fanfor moving air from the inletto the outlet, an air to air heat exchangerof the type that cools the air by diverting and cooling a portion of the air through an evaporative cooling means, heat exchange occurring across a plurality of barriersbetween the evaporatively cooled air and said incoming air, a vapor compression-type cooling system having an evaporator coilthrough which the outlet stream of air passes for further cooling of the outlet air, a condenser coilthrough which the evaporatively cooled air, stream that exits the air to air heat exchangerpasses, and a control systemthat at least determines the temperature of the roomair and controls the operation of the air-conditioner to operate only the air to air heat exchangerwhen the temperature is maintained below a pre-determined level, and operates both said air to air heat exchangerand the vapor compression-type cooling system when the temperature increases above a pre-determined level. The advantage of the invention is that it has a seasonal power efficiency of two to three times greater by comparison to an air-conditioning system operating only with a vapor compression-type system.
