Abstract
A cryogenic temperature control apparatus comprises a storage tank housing a quantity of cryogenic fluid, a housing defining a conditioned space, and a heat exchanger in thermal communication with the conditioned space. A first flow path fluidly connects the storage tank and the heat exchanger. A first valve is positioned along the first flow path to selectively fluidly seal the first flow path between the storage tank and the heat exchanger. A second flow path fluidly connects the storage tank and the heat exchanger. A second valve is positioned along the second flow path to selectively fluidly seal the second flow path between the storage tank and the heat exchanger.
