Abstract: The invention provides an ozone generator controlling apparatus capable of controlling an ozone generator so that when a discharge breakdown occurs in some discharge element, the operation of generating ozone can be continued without imposing a bad influence on the remaining normal discharge elements. When an anomaly occurs in one of or a plurality of discharge elements during the operation of generating ozone, the anomaly is detected by an anomaly detection means. In response to the detection of the anomaly, first output control means reduces the output of an AC power supply circuit to a sufficiently low level so that after the discharge element having the anomaly is isolated from the circuit the operation of generating ozone can be continued with the remaining normal discharge elements without interruption and without causing the normal discharge elements to encounter an overload current thus preventing them from being broken one after another.

The refrigerant passage is divided into a first section on the top side and a second section on the bottom side by a bridgewall. In the first section, a liquid or gas-liquid two-phase refrigerant is introduced from the bottom of the refrigerant passage so as to flow parallel to the feed gas. In the second section, a gas fraction of the refrigerant discharged from the first section flows.
