Refrigeration system for a cooler
First Claim
1. A self-contained cooler refrigeration system comprising:
- (a) a generally rectangular closed storage compartment including opposed side walls, an upper wall, a lower wall and front and rear walls at least one of said front and rear walls defining door access means substantially of glass,(b) circulation means including duct means disposed below the upper wall and having a midportion and opposed end portions, the midportion including air inlet means and the end portions including air outlet means located adjacent the side walls, and(c) the circulation means being arranged to draw air upwardly through the inlet means, to direct said air toward the side walls, cool said air and direct said cooled air downwardly through the outlet means adjacent the side walls to provide two counter flow air paths each defined at least in part by an opposed side wall.

Abstract
This cooler refrigeration system is for a cooler (10) having a storage compartment (12) including opposed side walls (16) an upper wall (18), a lower wall (20), and front and rear walls (22, 24) at least one of said front and rear walls (22, 24) providing an access door. The storage compartment (12) includes a circulation system (30) including a duct (32) disposed below the upper wall (18) providing an air inlet (34) in the midportion and air outlets (36) at the opposed end portions. The circulation system (30) provides two counter air flow paths A1, A2 by drawing air upwardly through the air inlets (34) by fans (40), cooling said air by directing the air outwardly across coils (38) disposed between each air inlet (34) and each air outlet (36) and directing said cooled air downwardly through each air outlet (36) and guiding the air along opposed side walls (16) to said lower wall (20) to be again drawn upwardly into the air inlet (34).
