  • Patent number: 10190788
    Abstract: An auto changeover mechanism for a thermostat. A heat and cool mode auto changeover with single or crossed setpoints may be an approach for doing a single setpoint auto changeover, an approach that can handle auto changeover with separate heat and cool setpoints that do not require the cool setpoint to always be higher than the heat setpoint, and also an approach that does not necessarily require a dead band between the setpoints. A hysteresis may be associated with switching to the other mode. The thermostat having the auto changeover mechanism may have a display of a mode that automatically changes between heat and cool.

  • Patent number: 10194562
    Abstract: A dew point of air entering an information handling system is determined based on the temperature and humidity of the air. Also determined is a temperature of facility cooling water entering the information handling system. A condensation mitigation procedure is activated if a difference between the temperature of the facility cooling water and the dew point temperature is less than a first threshold value. The condensation mitigation procedure includes reducing a flow-rate of the facility cooling water to a liquid manifold using a valve. The liquid manifold is in thermally-conductive contact with a heat-generating component included at the information handling system.

  • Patent number: 10132510
    Abstract: A system for heating water to improve safety and efficiency. The system may have normal operation measured in time. After a time of normal operation, a water temperature setpoint may be checked. If the setpoint is not at a certain level, normal operation may continue. If the setpoint is within the certain level, water temperature may be measured. If the water temperature is less than a desired level, one or more draws of water may be measured for a preset temperature drop. If the draws do not meet the temperature drop, a return to check the setpoint may be made. If the draws meet the temperature drop, the setpoint may be reduced and a time of normal operation may be measured to determine whether a burn cycle occurs within the time. If not, normal operation may continue; but if so, a return to check the setpoint may be made.

  • Patent number: 10126032
    Abstract: A system for cooling and controlling a cooling system having a variable speed compressor, a condenser, a variable flow regulator, a metering device, an evaporator, and a refrigerant. The system includes controlling the speed of the variable speed compressor by transmitting a control signal to the variable speed compressor such that the speed of the variable speed compressor is based on the control signal and lowering the speed of the variable speed compressor results in a lower flow rate of the refrigerant and thus a reduced rate of cooling. The system also includes selectively opening or closing the variable flow regulator such that a closed variable flow regulator restricts the flow of the refrigerant through the evaporator and thus reduces the rate of cooling.
