Abstract
Backup refrigeration is provided to a cryogenic refrigeration system comprising multiple cooling loops using a single backup coolant storage vessel. The backup coolant storage vessel is in fluid communication with at least one of the cooling loops, and the cooling loops are in fluid communication with each other. Each cooling loop, in turn, is in fluid communication with a refrigeration unit. In the event of lost coolant from one of the loops, coolant, e.g., liquid nitrogen, is transferred from the other loops to the loop that lost coolant, and the backup coolant storage vessel releases backup coolant into the system.
