A refrigeration system especially useful for refrigerating biological samples wherein a cryocooler, such as one employing a pressure wave from a pressure wave generator, is used to generate refrigeration for cooling liquid coolant or purging fluid, which is employed within hollow structures bordering an enclosed space of a storage unit or within the storage space of a storage unit and is subsequently cleaned of contaminants purged from the storage space.
The invention claimed is: 1. A refrigeration system comprising: (A) a storage unit having a storage space which contains biological material; (B) a purge gas generator, a gas contaminant cleaning system, a heat exchanger, a cryocooler having a cold head, means for passing gas from the purge gas generator to the gas contaminant cleaning system, means for passing gas from the gas contaminant cleaning system to the heat exchanger and then from the heat exchanger to the cold head of the cryocooler, and means for passing fluid from the cold head of the cryoc...
