  • Patent number: 11713905
    Abstract: A system and a method for reducing a risk of bacterial contamination in a water heater are disclosed. A bypass conduit is connected to cold water supply and hot water outlet conduits of the water heater with T-shaped fittings, the bypass conduit generally extending in a same horizontal plane as the fittings and running alongside a top surface of the water heater. A thermostatic mixing valve is integrated to the bypass conduit close to the fitting with the hot water outlet so that its mixed water outlet is connected to the fitting with the hot water and its cold water inlet is connected to the fitting with the cold water, its hot water inlet being blocked. The thermostatic mixing valve is adjusted to regulate the hot water temperature at the outlet of the system and to produce a thermosiphon loop in the system depending on whether there is extraction or no extraction of hot water from the water heater.

  • Publication number: 20220263316
    Abstract: A power control device for use in an AC power grid for regulating an electrical power a load that is supplied by the AC power grid consumes. The power control device has a frequency sensing functional block for detecting a deviation of the grid frequency from a nominal grid frequency and a logic functional block for performing a load adjustment process during which the power the load consumption is reduced. The load adjustment process is based at least in part on the variation of the frequency of the AC power grid. The load adjustment process is design such that for a plurality of power control devices the individual response produce a grid-wide effect that compensates imbalance between power generation and load in fashion that may reduce unwanted distortion in the AC power grid, such as flicker.

  • Publication number: 20210180829
    Abstract: A system and a method for controlling an electrical water heater as per a load shedding request signal are disclosed. A temperature sensor is positioned so as to measure a water temperature in a lower area of a tank of the water heater to be controlled. A controller continuously determines a salubrity index of the water heater as a function of the temperature measured by the sensor and a time measurement, and decides to interrupt an electrical power supply of the water heater through a switch so as to interrupt or not interrupt an operation of the water heater upon the load shedding request signal and only if the salubrity index meets a preestablished criterion.
