Abstract

Abstract An elongated cylinder is placed towards the front end of a vehicle such as an automobile at a lower level than the air conditioning unit evaporator drain and connected to the evaporator drain by a hose. This cylinder forms a reservoir, spray units are located at the ends or top of the reservoir and, condensate from the air conditioning unit in the reservoir is forced out of the reservoir into the spray units by internally applied air pressure. Outside air created by the vehicle forward movement is captured by one or more flanged pipes and provides the source for the internally applied air pressure. Condensate spray from the cylinder directed by the vehicle radiator fan flows onto the vehicle condenser core so as to assist in removing heat from the circulating freon sending a much cooler freon back into the vehicle.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 215 words
An arrangement for enhancing the performance of a vehicle air conditioning unit, said air conditioning unit including a condensor and an evaporator, said evaporator having a drain connected thereto for draining condensate collected therefrom, said arrangement comprising in combination: (a) an elongated cylinder (1) having a defined upper portion with a water condensate inlet (8) in said upper portion, said inlet (8) including a tube connected to said evaporator drain; brackets (10) connecting the cylinder (1) to the front of the vehicle at a level below the level of the evaporator drain, the elongated cylinder (1) being of a lesser length than the width of the vehicle; (b) air inlet units (4, 4') including pipes with an inlet flared mouth disposed to receive incoming air as the vehicle moves in the forward direction, said air inlet units extending out from said cylinder upper portion; and, (c) spray units (3) extending out from said cylinder with spray heads facing the condenser whereby, condensate from the vehicle air conditioning unit evaporator drain enters the cylinder through said inlet (8) while outside air enters said cylinder through said inlet units so that the air forces the condensate in the cylinder out of the spray units (3) onto the air conditioning condenser so as to cool the freon therein.
Claim 2
Dependent Claim 215 words
An arrangement for enhancing the performance of a vehicle air conditioning unit, said air conditioning unit including a condensor and an evaporator, said evaporator having a drain connected thereto for draining condensate collected therefrom, said arrangement comprising in combination: (a) an elongated cylinder (1) having a defined upper portion with a water condensate inlet (8) in said upper portion, said inlet (8) including a tube connected to said evaporator drain; brackets (10) connecting the cylinder (1) to the front of the vehicle at a level below the level of the evaporator drain, the elongated cylinder (1) being of a lesser length than the width of the vehicle; (b) air inlet units (4, 4') including pipes with an inlet flared mouth disposed to receive incoming air as the vehicle moves in the forward direction, said air inlet units extending out from said cylinder upper portion; and, (c) spray units (3) extending out from said cylinder with spray heads facing the condenser whereby, condensate from the vehicle air conditioning unit evaporator drain enters the cylinder through said inlet (8) while outside air enters said cylinder through said inlet units so that the air forces the condensate in the cylinder out of the spray units (3) onto the air conditioning condenser so as to cool the freon therein.
