Abstract
A low-temperature storage device includes an inner vessel, an outer vessel about the inner vessel, a thermal insulation layer between the inner vessel and the outer vessel, and a single heat exchanger in thermal communication with an interior of the inner vessel and adapted to be connected to at least one of an evaporator in a closed-loop refrigeration circuit and an open-loop evaporator for an externally-supplied cryogen. The inner vessel can be a vacuum-insulated vessel, and the heat exchanger can be an internal heat exchanger including at least two fluid circuits: a first circuit with one external connection and one internal connection into the inner vessel and the second circuit with two external connections.
