ABSTRACT:
A refrigerant precooler device, connecting into the Freon line of an existing air conditioning unit, and directing this freon through a finned cooling coil, and having a downdraft fan blowing air downward onto a supply of water in the bottom of the precooler device, and the fan blades being surrounded at a strategic location by a venturi shroud, which tends to disperse some of the air from the fan outward, and over the fins of the cooling coil, thereby causing an accelerated evaporation effect, with the added cooling of the Freon. A controlled supply of water in a reservoir at the bottom of the device is pumped upwards through a tubing device and into a pipe which is located onto the top of the cooling coil, and the pipe has a slot cut lengthwise of its bottom longitudinal dimension, and the pumped water drips out of the slot in the pipe, and drains downward over the fins of the cooling coil.
As stated, the air from the fan tends to cool the supply of water in the reservoir, and, the venturi shroud tends to direct some of the airstream outward, onto, and through the fins of the cooling coil, and, this venturi effect also tends to evaporate some of the water on the fins, which provides even more cooling for the refrigerant.
