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.

Refrigeration system

A refrigeration system for objects is disclosed. The system includes a refrigeration device and a defrost system. The refrigeration device provides a case or container defining a space for the objects, a first heat exchanger associated with the container for cooling a fluid communicating with the space to cool the objects and a second heat exchanger to receive a heat supply from an air source for warming the fluid. A system for cooling articles is also disclosed. The system includes a space configured to contain the articles, a first element to provide cooling of the articles within the space, a first coolant source to refrigerate the space by cooling the first element in a first state, and a second coolant source to elevate a temperature of the first element in a second state.

A system for refrigeration of products includes a case having a compartment defining a space configured to receive the products. A first heat exchanger is configured to cool a fluid communicating with the space to cool the objects. A second heat exchanger is configured to receive a heat supply from an air source to warm the fluid. At least one coolant supply line and at least one coolant discharge line are configured to direct the fluid in communication with the space.

Service case

A temperature controlled service case for storage and display of chilled or frozen products, including at least one compartment for product storage, at least one access opening providing entrance to the compartment, at least one shelf within the compartment for holding product, and refrigeration operatively associated with the compartment for maintaining a selected temperature therein. The refrigeration includes at least one cooling coil above the shelf with a cooling medium flowing therethrough, and cooling within the shelf with a cooling medium flowing therethrough. Coolant supply is also provided for supplying cooling medium to the cooling coil and shelf with separate coolant supply and discharge lines from the coolant supply to the cooling coil and shelf. In accordance with a further embodiment, the shelf is divided into separate sections. In accordance with a still further embodiment, means are provided to warm the coolant for at least one of said cooling coil and shelf.
