1. A heater-cooler apparatus for an extracorporeal perfusion system, the heater-cooler apparatus comprising:
a cold storage unit;
a refrigeration unit configured to charge the cold storage unit; and
at least one fluid circuit configured to (i) direct a heat transfer fluid through the refrigeration unit to cool the heat transfer fluid, (ii) direct the heat transfer fluid cooled by the refrigeration unit through the cold storage unit from the refrigeration unit to the cold storage unit to charge the cold storage unit, and (iii) provide the heat transfer fluid to the extracorporeal perfusion system,
wherein the cold storage unit comprises a chamber containing a liquid that freezes at a temperature above that to which the heat transfer fluid is cooled by the refrigeration unit, and a passage through which the heat transfer fluid is conveyed, the passage extending through the chamber.
