  • Leak detection logic for closed-volume system
    Patent number: 8844551
    Abstract: A method for detecting a leak in a closed-volume liquid system comprises circulating a fluid through a closed-loop with a pump having a reservoir and that is driven by an electric motor. The method also comprises sensing a pressure in the closed-loop, sensing current draw by the motor and sensing fluid level in the reservoir. The method further comprises determining a presence of a leak of fluid from the closed-loop based upon two of the sensed signals using a first leak detection logic, and determining the presence of a leak of fluid from the closed-loop based upon at least one of the sensed signals using a second leak detection logic.
    Type: Grant

  • LEAK ISOLATION LOGIC FOR CLOSED-VOLUME SYSTEM
    Publication number: 20120318366
    Abstract: A method for isolating a leak in a closed-volume liquid system comprises circulating a fluid through a plurality of isolatable zones and a non-isolatable zone in a closed-volume liquid system, detecting a leak in the closed-volume liquid system, isolating all of the isolatable zones from the non-isolatable zone, sequentially detecting if the leak is present in the non-isolatable zone and each of isolatable zones, and taking corrective action after the leak is detected.
