ABSTRACT:
The apparatus comprises a large, open ended air collector attachment above an external heat exchanger of a standard residential air conditioner, which ducts the exhausted heat exchanger air flow into the attic of a building through a substantially vertically ascending air flow tube. The combination of the fan exhaust pressure together with adiabatic expansion of the warm air rising in the air tube produces sufficient air flow within the attic to pressure ventilate and thereby cool an average household attic, by displacing air trapped within the attic. This, in turn, reduces the heat load into the air-conditioned spaces of the house, by reducing the heat radiated from the attic spaces downward through the ceiling of the housing.
