ABSTRACT:
This invention relates to a panel air chiller for use with a portable food storage unit. The panel air chiller includes in combination first and second spaced apart parallel panels that have thermal insulation disposed between and in contact with the panels. The thermal insulation material has formed therein at least a first and a second chamber between the panels thereby establishing passageways between the panels and through the thermal insulation material. Located in the first chamber is a means to extract heat from air passing thereover to thereby cool the air. At least one return air opening is provided through one of the panels to communicate with the portable storage unit. A fan is coupled to the space between the panels and to the first chamber to thereby draw air through the return air opening coupled to the portable storage unit. The return air so drawn moves past a means to extract heat from the air and cool the same and is thereafter delivered to and through the second chamber to at least one cool air supply opening. The cool air supply opening is adapted for coupling to the portable storage unit.
