System and method for varying ozone production based upon ozone demand

An ozone production system for producing ozone, the ozone production system comprising:

• a plurality of washing machines;
• an ozone generator for generating ozone for supply to the plurality of washing machines;
• an ozone supply conduit for supplying ozone from the ozone generator to each of the plurality of washing machines;
• and
• each one of the plurality of washing machines having a respective venturi located along a water supply conduit, between a water source and an inlet into the respective washing machine, and a throat of the venturi being connected to the ozone supply conduit so that, as water flows through the respective venturi from the water source into the respective washing machine, such water flow creating a negative pressure within the ozone supply conduit, and each respective venturi being located along the water supply conduit less than about 30 inches away from an inlet of the washing machine;
• and
• wherein at least one sensor is located so as to detect the negative pressure within the ozone supply conduit;
• a one way check valve is located along the ozone supply conduit, adjacent the throat of the venturi, and the one way check valve permits the ozone to flow into the water, as the water flows through the venturi, but prevents water from flowing through the one way check valve toward the ozone generator;
• and
• the at least one sensor is connected to a control box, coupled to the ozone generator, which controls ozone production of the ozone generator depending upon the negative pressure detected within the ozone supply conduit by the at least one sensor.

A method of producing ozone with an ozone production system, the method comprising:

• providing a plurality of washing machines;
• generating ozone, via an ozone generator, for supply to each one of the plurality of washing machines;
• supplying ozone, from the ozone generator to each of the plurality of washing machines, via an ozone supply conduit;
• locating a respective venturi, for each one of the plurality of washing machines, along a water supply conduit between a water source and an inlet into the respective washing machine, and connecting the ozone supply conduit to each respective venturi for supply of ozone thereto;
• permitting water to flow through the respective venturi, from the water source into the respective washing machine, so that such water flow creates a negative pressure within the ozone supply conduit;
• locating at least one sensor so as to detect the negative pressure within the ozone supply conduit;
• and
• connecting the at least one sensor to a control box, coupled to the ozone generator, to control ozone production of the ozone generator depending upon the negative pressure detected within the ozone supply conduit by the at least one negative pressure sensor/switch.
