ABSTRACT:
The present invention discloses a method and apparatus for maintaining cold carbonated water in a beverage dispensing device so that unacceptably warm water is not dispensed therefrom. A modified beverage dispensing apparatus is shown including a carbonated water supply, a cold plate, a cabonated water supply line extending through the cold plate, and in fluid communication with a carbonated water plenum immediately adjacent and in fluid communication with a plurality of beverage dispensing valves. An electronic control device connected to a temperature sensing thermostat located in the plenum and to a solenoid discharge valve of the plenum. The control device is also connected to a temperature sensing thermostat in the cold plate and to a pressure sensor located in the line between the source of compressed carbon dioxide and the carbonated water reservoir. In operation, the control device provides for sensing of the temperature in the plenum so that the solenoid valve can be operated to discharge carbonated water from the plenum if the temperature thereof rises above a predetermined value. So that the water therein can be replaced by water of a suitable lower temperature. The control device also senses cold plate temperature and CO2 pressure so that unacceptably high temperature or low pressure respectively thereof is indicated to the operator and so that the control device can interrupt beverage dispensing.
