Abstract

A two-phase versatile evaporative cooling heat exchange apparatus 2 for use to produce cool air for homes, factories or for use in vehicles both stationary and moving. The vessel 4 contains the components needed so ambient air 6 is drawn or forced into the evaporative pad 32 to begin the cooling process. The evaporative pad 32 is wetted by thermal liquid 26 being distributed by pump 20 for the first phase cooling 8. The evaporation process uses a portion of the thermal liquid 26 with the remaining, now cooled, excess thermal liquid 36 being returned to the base of vessel 8. The cooled thermal liquid 26 is pumped through the heat exchanger 40 for the second phase cooling 10. The cooled air 12 is delivered into the occupant space 18.

Claims

1. An air conditioning system utilizing evaporative cooling and a heat exchanger to produce cooler air than an evaporation system alone.

a primary vessel containing a means to draw ambient air first through an evaporative pad, and secondarily through said heat exchanger then disbursing the conditioned cooled air outwards;

a pump located in said vessel for pumping thermal liquid to said evaporative pad and said heat exchanger;

a downward passing of said thermal liquid through said evaporative pad is partially evaporated leaving excess said thermal fluid, now cooled, to return to the base of said primary vessel for reuse;

said thermal liquid, that has been cooled by evaporation, is pumped into said heat exchanger to add the other element of cooling before said conditioned cooled air is distributed outside of said vessel;

2. The present invention versatile enough that it may be operated on either AC or DC current and of the size that would satisfy permanent installation or portable use.

a permanently installed cooling unit of said present invention design that would be of the capacity to cool a home or industrial building.

a portable cooling unit of said present invention design that would be small enough to be transported from area to area.

a portable cooling unit of said present invention design that would be small and safe enough to be operated even in a moving vehicle.
