  • Publication number: 20220042687
    Abstract: A hydronic distribution system obtains, in real time, valve operating information from one or more valves arranged in a network, executes a speed determination algorithm which processes the valve operating information to determine a desired speed for one or more pumps to maintain a desired amount of process fluid flow of a process fluid to plural coils, and sets a speed of the one or more pumps, based on the desired speed for the one or more pumps that is determined.

  • Patent number: 11162690
    Abstract: A hydronic distribution system includes self-regulating valves networked together and operable to share valve temperature and valve position information with a microprocessor or other type of controller. The microprocessor runs one or more algorithms that process the temperatures and positions of the valves and then computes a desired speed for one or more variable speed pumps within the system. Controlling the pumps to operate at the desired speed and still maintain the correct amount of process fluid flow needed by the system reduces the overall energy use of the hydronic distribution system, saves on the operational lives of the pumps, and increases system efficiency.
