Abstract

The present application provides a cascade refrigeration system (100). The cascade refrigeration system may include a first side cycle (110), a second side cycle (120) with a second side cycle carbon dioxide refrigerant (310), and an auxiliary cooling system (330) to cool the second side cycle carbon dioxide refrigerant in the event of a power outage. The auxiliary cooling system includes an auxiliary carbon dioxide refrigerant.
