Abstract

A constant-temperature liquid supply apparatus includes a circulation route for circulating liquid between an inlet and an outlet connected to a processing apparatus, a tank that accommodates the liquid supplied through the inlet, a pump that discharges the liquid in the tank, a temperature adjusting unit that adjusts the temperature of the liquid, an outflow quantity measuring section that measures the flow rate of the liquid, a solenoid valve that controls whether the liquid should be circulated in the circulation route, and a controller. The controller switches from a normal mode of supplying the liquid to the processing apparatus to a stand-by mode of circulating the liquid in the circulation route, when the flow rate is zero, and the discharge quantity from the pump is smaller than that in the normal mode, to thereby lower the power consumption of the pump in the stand-by mode.
