An air conditioning cooling apparatus and method which includes the steps of supplying cooling air generated from a cooling apparatus into an air passageway formed below a floor; guiding the cooling air within the air passageway into an equipment assembly disposed on the floor through an opening located in the floor; communicating the cooling air introduced into the equipment assembly into a plenum and introducing the air released from within the equipment into the plenum and communicating the released air through the cooling apparatus for cooling the released air. The method permits temperature differential between the air supplied to the air passageway and the air introduced into the plenum from the equipment assembly to be 45° F. to substantially 40° F. so as to reduce the power necessary for operating on the fan of the blowing apparatus.
