Abstract
The invention relates to apparatus and a method for the creation and provision of a cryogenic cooling environment for at least a predetermined period of time within a predefined volume in a first chamber with a heat exchanger. The apparatus may include a second chamber with a heat exchanger and means for utilising ambient air, refrigeration apparatus to cool said ambient air to or below a predetermined temperature to create the cryogenic cooling environment in at least the second chamber at or below -110 degrees Celsius. The apparatus includes a compressor and control means for control of the operation of the apparatus to create an initial controlled ambient air cool down stage to create cooled air followed by the use of a vapour cycle refrigeration system in which the said cooled air is used as the means to create the cooling medium for said volume. There is also provided a method for allowing an intervention in the operation of a refrigeration system for creating a cryogenic storage environment which allows the system to regain a substantially ambient temperature condition to allow said intervention relatively quickly.
