A vapor cycle refrigeration air chiller having two separate refrigeration systems in a single unitized frame. The first system producing a continuous cooling effect when supplied with alternating current power from an external source. The second refrigeration system operates to cool eutectic plates during alternating current operation. Air distribution is modified by a damper integral with a transporter containing the chiller and airborne food tray carts. Cooled air enters the carts from the chiller for pulldown and storage during alternating current operation. For transportation the chiller utilizes a self-contained battery operated, direct current fan with the damper spring loaded open, allowing the air to circulate over the eutectic plates and then around the food tray carts maintaining product temperature.

A transporter air chiller for cooling foodstuffs in airborne storage and serving carts comprising: (a) a unitized vapor cycle refrigeration apparatus having a pair of refrigeration systems within a single frame and a common air flow arrangement for providing product cooling by removing heat through a refrigerant cooling agent; (b) an alternating circuit electrical power circuit integral with said first refrigeration system for activating cooling and providing air flow by electromotive means; (c) an alternating current and a direct current electrical power system integral with said second refrigeration system for cooling, storing and providing air flow of said common arrangement; (d) an air damper within said air flow arrangement rotatably attached on one side to said frame for isolating air flow from said first and second refrigeration systems allowing cooling effect from either circuit not in concert; and, (e) an insulated compartment in said chiller for housing the high pressure side of said refrigeration systems providing thermal isolation from the balance of said apparatus due to inherent low heat transfer characteristics while allowing ambient air to circulate through said refrigeration systems.
