摘要： System and methods of operating a water heater receiving power from an electrical grid. The water heater includes a heating element, a controller, and a first control circuit. The first control circuit including an energizing terminal and a microprocessor. The method includes connecting an energizing terminal of the first control circuit between a power output terminal of the controller and the heating element, receiving driving power from the controller based on a temperature signal. The method also includes receiving a control signal from the controller based on electrical grid information, and selectively energizing the heating element, by the microprocessor of the first control circuit and through the energizing terminal of the first control circuit based on the control signal.

摘要： Systems and methods are provided for adaptive flow across multiple water heaters. The system may include a plurality of water heaters provided in a cascaded arrangement, with each of the water heaters including a valve. The valves may be, for example, motorized isolation valves that may be automatically closed and/or opened by one or more controllers associated with the water heaters. This may allow for the system to automatically regulate the flow rate through each of the water heaters to provide for optimal usage of the cascaded water heaters. For example, if it is determined by the one or more controllers (based on sensor data from the water heaters) that a flow rate has decreased below a threshold value for a giving water heater firing rate, one or more valves may be closed such that fewer water heaters are used and the flow rate is increased.

摘要： A water heating system includes a burner and a gas valve fluidly connected to the burner to deliver a flow of combustible gas thereto. The gas valve has an adjustable throttle for the flow of combustible gas, along with a motor to adjust a position of the throttle. A controller is configured to determine a throttle position corresponding to a target air-fuel ratio of the burner during a calibration sequence, and to control the motor in order to operate the burner at that target air-fuel ratio throttle position during a start sequence. The controller is configured to monitor a characteristic of the burner during the start sequence, and to initiate the calibration sequence if the monitored characteristic exceeds an error threshold.

摘要： A water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively run only the pilot for at least part of a heating cycle to increase the recharge time of the rechargeable power storage device while still heating the water in the water heater.

摘要： A beverage preparation machine includes a thermal conditioning device, such as a heater or cooler. The thermal conditioning device contains a control unit for controlling a start-up phase of the thermal conditioning device from a temperature of inactivity to an operative temperature. The control unit includes a controller with a start-up profile for starting-up the thermal conditioning device, and the start-up profile has at least one parameter. The controller has a self-learning mode for adjusting the at least one parameter. A temperature sensor is connected to the controller for measuring a temperature of the thermal conditioning device. The self-learning mode causes the controller during a start-up phase to: calculate a ramp value representative of a rate of change in temperature during the start-up phase of the thermal conditioning device; adjust the at least one parameter as a function of the adjusted ramp value; and use the adjusted at least one parameter for a remainder of the start-up phase.

摘要： The present disclosure discloses a method and apparatus for measuring carbon emission of a district heating system, an electronic device, and a medium. The method includes: obtaining a steady carbon emission amount of a current district heating system using a pre-trained steady carbon emission flow model; obtaining a dynamic carbon emission amount of the current district heating system using a pre-trained dynamic carbon emission flow model; and counting a carbon emission amount of the current district heating system based on the steady carbon emission amount and the dynamic carbon emission amount. Therefore, the present disclosure can effectively identify carbon emission details of each link of a source, a grid, and a load of the district heating system, clarify carbon emission responsibilities on both a source side and a load side, and realize accurate measurement of carbon emission of the district heating system, which has high application value.
