1. A method for inhibiting microbial growth in a heat exchanging system used for human body temperature control during extracorporeal circulation, the method comprising:
coupling a temperature control liquid supply, a temperature control device and a heat exchanger, using fluid conduits, to form a temperature control circuit, wherein the temperature control device and the heat exchanger are disposed at separate locations;
circulating a temperature control liquid from the temperature control liquid supply through the temperature control circuit including at least one of the fluid conduits passing through the temperature control device and the heat exchanger, wherein the temperature control device is configured to regulate temperature of the temperature control liquid; and
circulating blood from a human body through the heat exchanger such that heat is exchanged between the blood and the temperature control liquid;
wherein the temperature control liquid includes a disinfectant to inhibit microbial growth in the temperature control device.
