  • Patent number: 7788943
    Abstract: A heat exchanger has at least one inlet and outlet to permit circulation of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin flat outer plates. Each of the thin sections of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then from one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use for cooling liquids, the heat exchangers are arranged within a frame and brought into contact with the liquid to be cooled. When the heat exchangers are used to cool liquid sufficiently to produce ice crystals, a rotating scraping device sweeps across the surface of the heat exchanger, removing any ice crystals that have formed.

  • Patent number: 7765812
    Abstract: A system for detecting a mis-connected state between communication lines for a multi-type air conditioner and a method thereof. The system comprises an indoor unit pipe temperature detection unit for detecting a temperature of an indoor unit pipe, and a microprocessor for controlling an opening of an electronic expansion valve based on a temperature detected by the indoor unit pipe temperature detection unit, comparing a temperature response characteristic of the indoor unit pipe with a preset temperature response characteristic of a normal indoor unit pipe based on an opening of the electronic expansion valve, and thereby judging whether the communication lines are mis-connected to one another or not. An indoor unit from which the mis-connection has been generated is fast detected, and error information is displayed. Accordingly, the mis-connected state between the communication lines is restored, thereby preventing a damage of the system due to the mis-connection.

  • Patent number: 7762089
    Abstract: A refrigerant charging system and method for charging a refrigeration system with a vapor-phase refrigerant includes a refrigerant source, an input line, a sensor and a pressure regulator. The input line connects the refrigerant source to the refrigeration system. One or more valves are disposed between the refrigerant source and refrigeration system to regulate the pressure of the refrigerant being introduced into the refrigeration system, and the sensor measures the pressure of the refrigerant entering the refrigeration system. A pressure regulator can also be used to regulator the flow of refrigerant. Once the pressure of the refrigerant reaches a predetermined pressure, the refrigeration system is fully charged, and the transfer of refrigerant to the refrigeration system is stopped.

  • Patent number: 7757500
    Abstract: An ice making, and delivery apparatus for making and delivering ice to different ones of a plurality of receptacle units is provided, in which ice delivered via a conduit to a diverter valve mechanism, is diverted from alignment with one ice discharge line to another, depending upon sensors in ice receptacles recognizing a level of build-up of ice in any given receptacle, for computer control of a gearmotor for moving the diverter valve from one position to another. Various controls are provided for preventing ice build-up, and for operating the diverter valve during a “dwell” period of ice movement in the conduit, as distinguished from a “push” period of ice movement in the conduit to the diverter valve. A force multiplication technique is employed for moving the diverter valve notwithstanding the presence of ice therein.
