Abstract: A heat exchanger module includes a skin condenser and a skin evaporator. The skin condenser includes an inner condenser plate, an outer condenser plate coupled to the inner condenser plate and a condenser tube channel formed on one of the inner condenser plate and/or the outer condenser plate. The evaporator includes an inner evaporator plate, an outer evaporator plate coupled to the inner evaporator plate, and an evaporator tube channel formed on one of the inner evaporator plate and/or the outer evaporator plate. The heat exchanger also includes an insulation layer extending between the inner condenser plate and the inner evaporator plate. Each of the plates that form the skin condenser and/or evaporator can be formed from different materials and/or have different material thicknesses to reduce heat transfer through the insulation layer from the condenser to the evaporator while also promoting heat transfer through natural convection with surrounding air.

Abstract: The present application provides a cooler for cooling a beverage fluid flow. The cooler may include a thermoelectric cooling device in communication with a fluid heat exchanger with the fluid flow therein and a water permeable membrane. The cooler further may include a fan positioned about the water permeable membrane for evaporative cooling therein.

Abstract: The present application provides a compressor for use with a flow of carbon dioxide. The compressor may include a first stage compression mechanism for compressing the flow of carbon dioxide from a low pressure to an intermediate pressure, an oil separator downstream of the first stage compression mechanism, and a second stage compression mechanism positioned downstream of the oil separator for compressing the flow of carbon dioxide from the intermediate pressure to a high pressure.

Abstract: The present application provides a cooler. The cooler may include an outer frame, a product space within the outer frame, and a number of shelf assemblies positioned within the product space. The shelf assemblies may include an evaporator and a phase change material therein.

Abstract: The present application provides a refrigeration system. The refrigeration system may include a compressor and a condenser downstream of the compressor. The condenser may include a refrigerant tube, an outer jacket surrounding the refrigerant tube, and a phase change material positioned between the refrigerant tube and the outer jacket and in contact with the refrigerant tube.

Abstract: The present application thus provides an expansion device for a refrigeration system. The expansion device may include a multi-way valve with an inlet port, a number of outlet ports, and a selectable valve member movable between a number of open positions related to the outlet ports and a closed position, and a number of capillary tubes in communication with the outlet ports.

Abstract: A sealed unit of refrigerant fluid for a refrigeration appliance, comprising a hermetic compressor (1), a condenser (3), an evaporator (2), an expanding device, and conducting tube (4) of refrigerant fluid, at least one of the parts consisting of the condenser (3) and the evaporator (2) being defined as a prismatic body which is at least partially tubular, the component parts of the sealed unit being relatively displaced from an inoperative position of transportation, in which the hermetic compressor (1) and the conducting tubes (4) remain contained within a contour defined by the contour of at least one of the parts consisting of the condenser (3) and the evaporator (2), to a mounting operative position in a refrigeration appliance.
