  • Cryogenic temperature control apparatus and method
    Patent number: 6631621
    Abstract: A method of temperature control in a cryogenic temperature control apparatus comprises providing a heat exchanger in thermal communication with an air-conditioned space. The heat exchanger includes an air inlet and an evaporator coil having an outlet. The method further comprises providing a first temperature sensor being operatively coupled to a controller, measuring the temperature in the outlet and sending the temperature in the outlet to the controller, providing a second temperature sensor being operatively coupled to the controller, measuring the temperature in the air inlet, and sending the temperature in the air inlet to the controller, and providing a plurality of temperature control values. The flow of cryogen from a storage tank to the evaporator coil is altered each time the temperature in the outlet passes one of a first plurality of temperature control values and each time the temperature in the air inlet passes one of a second plurality of temperature control values.

  • Control method for a self-powered cryogen based refrigeration system
    Patent number: 6609382
    Abstract: A method of temperature control in a cryogenic system, wherein the system includes a cryogenic tank. The method comprises providing a motor speed sensor which determines a motor speed, providing a pressure sensor which determines a cryogenic pressure, providing a temperature sensor in the conditioned space which measures a temperature within the conditioned space, providing a deprived integral region, and generating an overriding control signal at the proportional-integral-derivative controller when the temperature and the pressure are beyond a temperature set point and a pressure set point.
