1. A system comprising:
a high side heat exchanger configured to remove heat from a refrigerant;
a flash tank configured to:
store the refrigerant from the high side heat exchanger; and
discharge a flash gas;
a first load configured to use the refrigerant from the flash tank to remove heat from a first space proximate to the first load;
a second load configured to use the refrigerant from the flash tank to remove heat from a second space proximate to the second load;
a first compressor;
a second compressor configured to compress the refrigerant from the second load and the first compressor; and
a thermal storage tank configured, when a power outage is determined to be occurring, to:
receive at least a portion of the flash gas from the flash tank;
remove heat from the received flash gas, thereby condensing at least a portion of the received flash gas to a liquid refrigerant;
direct at least a portion of the liquid refrigerant to the flash tank;
wherein, the thermal storage tank is further configured, when the power outage is determined not to be occurring, to direct refrigerant to the second compressor.
