    Abstract: An improved refrigerator is provided with a freeze tolerant valve for the water tank assembly in the refrigerator. The valve includes a body with an internal plastic spool which minimizes the volume of water within the valve, and which provides a space in the valve to accommodate freezing water in the valve. The valve will not crack or fail in the event of a temperature control problem in the refrigerator which results in frozen water within the valve.

  • Publication number: 20100307173
    Abstract: An external heat exchanger is used to transfer heat from a compressor lubricant to an expanded working fluid, thereby cooling the lubricant. The heat exchanger may also be used to sub-cool condensed working fluid with the same flow of expanded working fluid. A horizontal scroll-type compressor includes an intermediate lubricant sump between a main bearing support and a scroll member. A counterweight on the crankshaft can travel through the lubricant in the intermediate sump to splash the lubricant around. A horizontal scroll-type compressor can include multiple machined surfaces that are utilized to precisely center and align components of the compressor.

  • Patent number: 7757498
    Abstract: A beverage dispensing system is characterized by a beverage dispenser and a beverage dispensing tower located remote from the beverage dispenser. The beverage dispenser has a cold plate and the tower has a heat exchanger. To deliver chilled beverage components to and for dispensing by the tower, a closed-loop water circulating circuit extends between and includes a fluid chilling circuit of the cold plate and a heat exchange circuit of the heat exchanger. The closed-loop circuit is fluid coupled to a beverage valve of the tower to deliver chilled water to the valve, and a supply of beverage syrup is fluid coupled to the tower valve through a fluid chilling circuit of the heat exchanger for delivery of chilled syrup to the valve for mixing with chilled water in the dispensing of a beverage from the tower valve.

  • Publication number: 20100162741
    Abstract: A heating/cooling system includes a closed circuit refrigeration system including an evaporator. Water circulating through a closed water circuit exchanges heat with refrigerant in the evaporator, cooling the water for a cooling application. The water can also be heated by a boiler, and the heated water is used to heat a space. A water pump flows the water through the water circuit. When a current sensing relay detects a power failure, a boiler control algorithm is initiated to “trick” a motor of the compressor into believing the heating/cooling system is operating in a heating mode. Therefore, a compressor failure alarm is not generated. The water pump is powered by a battery pack during the power failure. Water continues to flow through the water circuit, preventing the water from freezing.

  • Patent number: 7735327
    Abstract: An active thermal insulation system is disclosed. The system utilizes a cool air source or ambient air below a threshold temperature in conjunction with a phase change material and/or conventional insulation. In a controlled manner, the cooled air or ambient air facilitates the transition of the phase change material from a substantially liquid state to a substantially solid state allowing the solid phase change material to absorb heat. Cooled air or ambient air may be directed to the phase change material via a gap or plenum capable of introducing the cooled air or ambient air adjacent to the phase change material. A fan, blower or air intake device may be used to direct ambient air to the gap or plenum.

  • Patent number: 7628023
    Abstract: An apparatus and method are provided for cooling a dispensed beverage. Direct cooling of the beverage is achieved by circulation of a refrigerant in contact with a reservoir that holds the beverage just prior to being dispensed. The reservoir is disposed within a dispense font. The open space within the font acts as an evaporator of a closed refrigeration loop thereby achieving cooling without having to use a separate heat transfer loop. A refrigeration subsystem is mounted directly adjacent the dispense font to provide a controlled flow of refrigerant to the open space within the font. Evaporated refrigerant is recycled in the refrigeration subsystem.
