Patent ID: 7364095

Claim:
An apparatus for judging a target to be temperature-regulated, which judges whether a target to be temperature-regulated is a first target to be temperature-regulated having a large pressure loss or a second target to be temperature-regulated having a small pressure loss when a fluid is supplied from a fluid supply source to the target to be temperature-regulated, comprising: a flow rate adjusting means which adjusts a flow rate of the fluid supplied to the target to be temperature-regulated; a flow rate measuring means which measures the flow rate of the fluid; a pressure measuring means which measures a pressure of the fluid; and a judgment means which judges, when a prescribed flow rate value Q 3 and prescribed pressure value P 3 on a corresponding relationship between the flow rate and the pressure of the fluid supplied to the first target to be temperature-regulated are determined in advance and the flow rate is adjusted by the flow rate adjusting means, that the target to be temperature-regulated is the first target to be temperature-regulated if the measured value of the flow rate measuring means reaches the prescribed flow rate value Q 3 and the measured value of the pressure measuring means reaches the prescribed pressure value P 3 , but if not, judges that the target to be temperature-regulated is the second target to be temperature-regulated.
