    摘要: A liquid carbon dioxide refrigeration system is provided. The refrigeration system may include a storage tank arranged for storing liquid carbon dioxide, and a vessel arranged to separate carbon dioxide into a vapor carbon dioxide portion and a liquid carbon dioxide portion. A first conduit is coupled to the storage tank and the first vessel such that liquid carbon dioxide can pass from the storage tank to the first vessel. A second conduit is coupled to the first vessel such that the liquid carbon dioxide portion can pass into a refrigeration device, and a third conduit is coupled to the first vessel and the first conduit to recycle the vapor carbon dioxide portion back to the first conduit. The third conduit may include a refrigeration package to compress and liquefy the vapor carbon dioxide portion

    摘要: A cryogenic freezer with cryogenic vapor control is disclosed. The cryogenic freezer is characterized in that the vapor control system is adapted to control the speed of the transition fan which moves some of the cryogen from a first cryogenic freezer to a second freezer in response to differences between the temperature of the process room, operating temperature of the cryogenic freezer; and a temperature of the exhaust. By adjusting the transition fan speed in response to such temperature differences the vapor control system operates to limit the flow of air from the process room into the freezer and also limits cryogen vapor flow from the freezer to the process room.
