摘要： A control method is provided for a cryogenic refrigeration system having an evaporator-heater coil, an electronically controlled valve for regulating the amount of cryogen to the coil, and a vapor motor driven by the cryogen that is coupled to both an alternator for recharging a battery, and a fan for generating a discharge air flow through the coil and into a conditioned space. The shaft rpms of the vapor motor is determined by a rectified output of the alternator, and the electronically controlled valve is incremented or decremented so that the shaft rpms stay above a preselected amount sufficient to both to recharge the battery of the system, and to circulate sufficient air in the conditioned space to avoid undesirable temperature non-uniformities therein. The pressure of the cryogen in the system is further continuously measured, and the electronically controlled valve is incremented or decremented in order to maintain a sufficient pressure to maintain the cryogen in a gaseous state. Finally, the difference between the measured temperature of the return air in the conditioned space and a set point temperature is determined, as well as the rate of change of the measured temperature and the acceleration or deceleration associated with the rate of temperature change. The electronically controlled valve is further incremented or decremented in accordance with a fuzzy logic routine partially on the basis of the temperature difference, the temperature rate of change, and the acceleration or deceleration of the temperature rate of change dependent upon how close the measured temperature is with respect to the set point temperature.

摘要： Both an system and method are provided for transferring liquid carbon dioxide from a storage tank pressurized at 300 psi to a truck-transportable tank pressurized at about 110 psi. The system includes an inlet conduit having a hose portion connected between the storage and transportable tanks for conducting a flow of liquid carbon dioxide therebetween, and a vent hose connected to the transportable tank for venting gaseous carbon dioxide. Pressure regulators are connected to the inlet and vent hoses, respectively. In operation, the pressure regulator connected to the inlet conduit reduces the pressure of the flow of liquid carbon dioxide entering the transportable tank from 300 psi to 175 psi, while the pressure regulator connected to the vent conduit maintains a back pressure of 110 psi in the transportable tank while the allowing the venting of gaseous carbon dioxide. Automatic shut-off and purging mechanisms are provided for shutting off the flow of liquid carbon dioxide when the transportable tank is filled, and purging the inlet hose. A muffler is connected to the outlet of the vent hose for reducing the noise associated with the venting of gaseous carbon dioxide. The system allows an operator to easily and automatically fill a transportable cryogenic storage tank with liquid carbon dioxide with a minimum amount of waste and noise.

摘要： Air conditioning and refrigeration apparatus for controlling the temperature of a conditioned space to a predetermined temperature band adjacent to a predetermined set point temperature via cooling and heating cycles utilizing a supply of pressurized cryogen. A cryogen driven motor drives a fan and an alternator. The alternator provides control voltage for operating electrical control devices which select a heating cycle, or a cooling cycle, as required, and which control the flow of cryogen during the selected cycle. Electrical load on the alternator, and thus a load on the vapor driven motor, is minimized to maintain air delivered by the fan to the conditioned space at a level which provides a substantially uniform air flow and temperature throughout the conditioned space. A cryogen flow control valve is motor controlled and only requires electrical energy when a change in the cryogen flow rate is desired. Heating and cooling cycle selecting valves require no electrical energy during a cooling cycle, and very little electrical energy during a heating cycle, as cryogen pressure is utilized to shift the heating and cooling cycle selecting valves when a heating cycle is desired.

摘要： A refrigeration system associated with a conditioned space to be controlled to a predetermined set point temperature via heating and cooling cycles. The refrigeration system includes a fluid flow path through which a predetermined liquid is circulated. The fluid flow path includes a slush tank and first and second heat exchangers, with cryogen from a supply vessel being expanded into liquid disposed in the slush tank. The first heat exchanger is disposed to condition the air of the conditioned space, and the second heat exchanger is in heat exchange relation with heating apparatus. The first heat exchanger and slush tank are interconnected when the conditioned space requires a cooling cycle, and the first and second heat exchangers are interconnected when the conditioned space requires a heating cycle. Cryogen of the cryogenic cooling apparatus is thus not expended to heat the conditioned space, or for defrosting purposes.

摘要： Methods and apparatus for controlling a conditioned space to a predetermined set point temperature, utilizing a supply of cryogen. Cryogen is drawn from the supply in a flow path to provide a cooling mode via a heat exchanger disposed in the flow path. A vapor motor in the flow path, downstream from the heat exchanger, drives a fan which moves air between the conditioned space and the heat exchanger. Heat is applied to the cryogen downstream from the heat exchanger, after all cooling modes have been performed, to provide the desired fan horsepower, without interfering with a cooling cycle. A by-pass flow path selectively directs cryogen directly to the vapor motor, by-passing the heat exchanger, to provide air circulation in the conditioned space when the temperature of the conditioned space is satisfied.
