Assignee:

Delaware Capital Formation, Inc.

International Classification:

F25D017/06
F25D017/02
F25B007/00

US Classification:

062/335000, 062/434000, 062/096000

Abstract:

A refrigeration system includes a first cooling system having a refrigerant in thermal communication with a heat exchanger device to provide a first cooling source. A second cooling system has a coolant in thermal communication with the heat exchanger device and a refrigeration device is configured to receive the coolant. A third cooling system is configured to provide a second cooling source to the coolant when the first cooling source is unavailable, so that a pressure of the coolant does not exceed a predetermined level when the first cooling source is unavailable.

Abstract:

Embodiments of the present technology are directed to devices, systems, and methods of delivering ice under high ambient temperatures. A transportable container houses an air-conditioning system with a cascade heat exchanger coupling the air-conditioning system with a separate refrigeration system in the container. The separate refrigeration system provides cooling energy for a cooling device while rejecting a heat load to the air-conditioning system for rejection to ambient temperatures.
