摘要： A water heater includes a tank defining an interior space adapted to contain water and a shroud over the water heater and defining a component space inside the shroud. A first pipe nipple is coupled to a spud of the water heater, the first pipe nipple and spud defining a non-collinear axis that is non-collinear with a pipe axis of a pipe to be fluidly connected to the tank. A flexible connector is connected at one end to the first pipe nipple along the non-collinear axis. A second end of the flexible connector is positioned collinear with the pipe axis. A second pipe nipple is coupled at one end to the second end of the flexible connector and coupled at an opposite end with the pipe. Fluid communication is established between the pipe and the interior space of the tank through the pipe nipple and flexible connector.

摘要： A fluid heating system including a burner unit is operated based on feedback control loops. The fluid heating system comprises a burner unit configured to heat a fluid, a sensor configured to sense a characteristic of the appliance, and a controller coupled to the burner unit and the sensor. The controller includes an electronic processor and a memory. The controller is configured to receive a first signal corresponding to the characteristic from the sensor, determine, based on the first signal, a first feedback loop control, control combustion of the burner unit based on the first feedback loop control, determine, based on the first feedback loop control, a second feedback loop control, and control combustion of the burner unit based on the second feedback loop control.

摘要： A gas-fired water heater including a water tank, a combustion chamber, a burner assembly disposed within the combustion chamber, a gas valve for controllably supplying gas to the burner assembly, a temperature sensor coupled to the combustion chamber, wherein the temperature sensor generating a signal related to the temperature of the combustion chamber, and a controller having an electronic processor and memory. The controller is configured to receive the signal at a first predetermined time and at a second predetermined time, calculate a change in temperature based on the signal received at the first predetermined time and the signal received at the second predetermined time, compare the change in temperature to a rate of change threshold to produce a first comparison, and shut the gas valve in response to the change in temperature being less than the rate of change threshold.

摘要： A water dispensing unit adapted for communication with a water supply includes a main body including a first end, a second end opposite the first end, a first axis extending through the first and second ends, and a second axis extending perpendicular to the first axis. The water dispensing unit additionally includes an inlet configured to receive water from the water supply, an outlet configured to dispense water, wherein the outlet extends along an outlet axis, an inner wall including a reflective liner, and a light emitting diode positioned within the main body. The outlet axis is oriented at an angle relative to the second axis to direct water from the water supply toward the light emitting diode before exiting through the outlet.

摘要： A diffuser is provided for use in a thermal storage tank. The diffuser includes a fluid inlet to receive a flow of liquid into the diffuser, and a fluid outlet to discharge the flow of liquid out of the diffuser into an internal volume of the thermal storage tank. A flow circuit extends between the fluid inlet and the fluid outlet. A plurality of flow sections are sequentially arranged along the flow circuit. Each one of the plurality of flow sections defines a cross-sectional flow area for the flow of liquid. The cross-sectional flow area within any one of the plurality of flow sections is greater than the cross-sectional flow area within any of the plurality of flow sections arranged upstream of said one of the plurality of flow sections.

摘要： A system and method for treating water containing at least one contaminant. The system and method include a water treatment module such as a reverse osmosis unit. An electrochemical contaminant detection system is positioned in the waste water stream of the water treatment module. The contaminant detection system includes a contaminant sensor and a water quality sensor module. The contaminant sensor measures the concentration of the contaminant in the waste water stream and the water quality sensor module measures one or more water quality parameters of the waste water stream. A processor uses an algorithm to determine the concentration of the contaminant in the feed water based on the measurements of the contaminant sensor and water quality sensor module.

摘要： A multi-cavity gas-air mixing device includes at least two mixing cavities each having an air inlet and a mixture outlet communicated with a combustor, wherein each of the mixing cavities has a built-in gas pipeline, each of the gas pipelines is provided with a gas jet, and the orientation of the gas jet is intersected with a flow direction of air entering into the mixing cavities. The device effectively segments the gas-air mixer and achieves a large load regulation ratio, without producing condensate water at any load segment, thereby improving the system reliability and service life. The built-in gas pipeline not only actively controls the fuel in the open-close control pipeline, but also reduces the volume of the mixer and largely decreases the cost.
