1. A cooling method comprising:
sensing a first temperature at a first location in a fluid circuit;
determining whether the first temperature is greater than a first predetermined temperature;
if the first temperature is not greater than the first predetermined temperature, cooling a fluid using ambient air;
if the first temperature is greater than the first predetermined temperature, cooling the fluid using the ambient air and a refrigeration circuit;
sensing a dry bulb temperature of the ambient air;
sensing a second temperature at a second location in the fluid circuit;
determining whether the dry bulb temperature is greater than the second temperature;
if the dry bulb temperature is greater than the second temperature, cooling fluid flowing through the fluid circuit using the refrigeration circuit;
determining whether a fan power is greater than a predetermined power;
if the fan power is not greater than the predetermined power, cooling the fluid flowing through the fluid circuit using the ambient air; and
if the fan power is greater than the first predetermined temperature, cooling the fluid using the ambient air and the refrigeration circuit.
