Claim:
1. A method of supplying a temperature control fluid to a temperature control system that includes a first fluid path into which a liquid regulated to have a first temperature is supplied as a first fluid and in which a first variable valve of controlling a flow rate of the first fluid is provided; a second fluid path into which a liquid regulated to have a second temperature different from the first temperature is supplied as a second fluid and in which a second variable valve of controlling a flow rate of the second fluid is provided; a joint path through which a mixed fluid of the first fluid and the second fluid is supplied to a temperature control target object; a collection path through which the fluid supplied to the temperature control target object is collected; a bypass path in which a third variable valve is provided and through which a part of the fluid flowing in the collection path is circulated into the temperature control target object; and a circulation pump provided in the collection path, and that controls a temperature of a component of a semiconductor manufacturing apparatus as the temperature control target object, the method comprising: a first fluid supplying process of supplying the first fluid for a preset time period by respectively opening the first variable valve and the third variable valve at preset degrees of openness; a second fluid supplying process of supplying the second fluid for a preset time period by respectively opening the second variable valve and the third variable valve at preset degrees of openness; and a circulation pump driving process of driving the circulation pump in a state that the fluid flowing in the collection path is filled in the circulation pump, after the second fluid supplying process.
