Abstract: 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.

Abstract: 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.

Abstract: Both a system and method are provided for achieving temperature control in a refrigeration circuit by providing a bypass flow of saturated, gaseous refrigerant from the receiver tank to a point in the circuit downstream of the evaporator coil. The system includes a bypass conduit for conducting a bypass flow of saturated, gaseous refrigerant from an upper portion of the receiver tank to a point in the circuit between the evaporator coil and a suction line throttling valve to partially offset the cooling of the evaporator coil from the expansion valve. The bypass conduit includes a valve mechanism for modulating this flow to achieve a desired temperature setpoint. The system also includes a temperature monitoring sensor located in a space conditioned by the refrigeration circuit, as well as a microprocessor. The input of the microprocessor receives an electrical signal generated by the monitoring sensor indicative of the temperature of the space. The output of the microprocessor is connected to the valve mechanism in order to modulate the flow of bypass refrigerant to achieve a desired temperature setpoint in the conditioned space.

Abstract: In a transport temperature control system having a cooling and heating mode of operation an apparatus and method are provided for enhancing the heating capacity during the heating mode of operation. A second expansion valve is provided to connect the higher pressure liquid line to the refrigerant circuit downstream of the evaporator. When additional refrigerant is needed in the heating circuit to increase heating capacity, especially during low ambient temperature operating conditions, the second expansion valve is caused to open to admit more refrigerant to the system. After passing through the second expansion valve low pressure gas is passed to the compressor, optimizing compressor efficiency such that an increased amount of hot refrigerant gas is delivered to the evaporator for enhanced heating capacity.

Abstract: Both a system and method are provided for mapping the magnitude of residual compressive stresses over the surface of a ferromagnetic machine component, such as a valve ring of the type used in refrigeration compressors. The system includes an eddy current probe having a detection coil for emanating a fluctuating electromagnetic field that shallowly penetrates the surface of the valve ring or other ferromagnetic component, a probe circuit connected to the coil for both conducting a high frequency alternating electric current through the coil and detecting changes in the impedance in the coil, and a scanning mechanism having a turntable for supporting and rotating the component. A support arm positions the coil of the eddy current over a central portion of the valve ring while the ring is rotated by the turntable and changes in coil impedance are detected by the probe circuit. A microprocessor converts the fluctuations in the impedance detected by the eddy current probe circuit into residual stress values, and correlates these values with regular positions on the valve ring in order to generate a map of the residual surface stresses over the ring.

Abstract: A method for controlling a transport refrigeration system is provided that advantageously avoids the top-freezing of items stored in a conditioned space without the need for modulating the flow of refrigerant through the heater-evaporator coil that heats and cools the space. The method includes the steps of operating the refrigeration system in a cooling mode at high speed for no more than 300.degree. minutes below the temperature set point of the conditioned space to rapidly cool the space. Next, the system is operated in a low speed heating mode in order to raise the temperature of the conditioned space to no more than about 5.degree. F. above set point in order to avoid top-freezing items in the conditioned space. Thirdly, the refrigeration system is operated in a low speed cooling mode to reattain a temperature set point assigned to the conditioned space. If necessary, these three basic steps of the method may be reiterated in order to stabilize the temperature of the space at set point. The method is particularly applicable to refrigeration systems capable of cooling or heating multiple conditioned spaces.

Abstract: A method of determining the condition of a battery which backs up a real-time clock (RTC) when a main power supply fails or is disconnected, in a system which includes a controller having a volatile random access memory (VRAM) and a non-volatile random access memory (NVRAM). The method includes the steps of periodically storing the time value of the RTC in NVRAM, and periodically writing a predetermined data pattern in VRAM, while the main power supply adequately powers the real time clock. The method then includes the steps of detecting a power-down condition of the main power supply, and terminating the recording and writing steps when the detecting step detects power-down. Return of main power, or power-up, is then detected, with the data pattern stored in VRAM then being compared with the predetermined data pattern. When the patterns are not the same, indicating more than a transitory loss of main power, the difference between the time value indicated by the RTC upon power-up and the last time value of the RTC stored in NVRAM before power down is compared with a predetermined constant time value. When the RTC has not incremented by at least the predetermined constant time value the method includes the step of indicating that the back-up battery is bad.

Abstract: A method of adding asynchronous logging of data relative to events into a time based data logger which stores operator initiated headers in a data array, as well as synchronously storing data relative to variables of a transport refrigeration unit at predetermined constant time intervals. The operator associated headers include a preamble having a predetermined number of data bytes which include a header designator and a digital code which identifies the specific type of header being entered. An event header is provided having a preamble which includes the same number of data bytes as the preamble of the operator associated headers, for each type of event to be asynchronously stored in the data array. The header designator associated with the operator associated headers is inserted into the preamble of each of the event headers. A digital code is provided which identifies each event header, and the digital code is inserted into the preamble of each of the event headers. A data field follows the preamble of each event header, with predetermined data being inserted into the data field when an event occurs. An event header is stored in the data array asynchronously, at the time the associated event occurs. Each event header is time stamped when stored in the data array, and data stored in the data array is downloaded to a predetermined device, including asynchronously stored event headers and synchronous data stored at predetermined time intervals.
