摘要： A hot water circulation system comprises a water heater having a cold-water inlet and a hot water outlet. A water pump circulates water through the water heater to produce hot water. The hot water is circulated to a thermal bypass valve, which is configured to close when hot water contacts a heat activated seal. A bypass circuit is coupled between the hot water outlet and the cold water inlet of the water heater. The bypass circuit prevents hot water from circulating from the hot water outlet to the cold-water inlet when the thermal bypass valve is open and promotes circulating hot water from the hot water outlet to the cold water inlet when the thermal bypass valve is closed. Upon a temperature sensor sensing hot water entering the cold-water inlet, the water heater turns of the water pump.

摘要： In a method for operating a heating system, a heating circuit medium is guided in an overall heating circuit and in first and second sub-heating circuits connected to the overall heating circuit. A heating circuit medium volumetric flow through the sub-heating circuits is defined by a valve device and fed to the second sub-heating circuit via a first valve device connection and/or guided via a second valve device connection. The heating circuit medium volumetric flow is fed via a connection of the valve device connected to the overall heating circuit. If necessary, the heating circuit medium volumetric flow is fed to the first sub-heating circuit via the second connection of the valve device, and if necessary, the heating circuit medium volumetric flow is delivered via a bypass on the second sub-heating circuit. If necessary, the heating circuit volumetric flow is guided through a buffer store at the bypass.

摘要： The present disclosure provides a water heating system for efficient heating of water for immediate use that fits either to industrial applications or household applications. The water heating system is suitable to be combined with a solar heating unit and it can be operated on electric power or on gas-based heating units for providing hot water to multiple consumers for household or industrial utilization. Furthermore, the system can be stand-alone, operating without any additional water heating system and can provide an immediate stream of hot water, e.g. it can be installed within a water supplying appliance. The water can operate in two modes: (1) heating for immediate use of hot water; and (2) heating water to be contained in a reservoir for later use. The system uses a two (bi) directional flow valve.

摘要： The prompt hot water and water conservation system includes a hot water supply pipe connected to a hot water heater outlet. A discharge faucet is connected to the supply pipe. A return pipe is connected to the supply pipe and to a hot water tank drain. The return pipe carries cooled water to the drain for reheating. Reheated water circulates into the supply pipe. A flow control device, in the return pipe, includes a chamber that houses a sphere. Return water flow moves the sphere toward a stop and permits unimpeded movement of water into the tank drain for reheating. When the faucet is opened, water flows from the tank drain into the flow control device. The sphere is moved to contact a small end of the chamber and substantially stop flow through the return pipe. Water is circulated through the system by increased density of cooled water.

摘要： A furnace for a heating, ventilation, and air conditioning (HVAC) system, comprises a burner configured to ignite a mixture of air and fuel and a sensor configured to detect a parameter indicative of an intensity of sound generated by the furnace and configured to transmit a signal indicative of a value of the parameter. The furnace further comprises a controller configured to receive the signal indicative of the value of the parameter, compare the value of the parameter to a threshold value, and in response to a determination that the value of the parameter meets or exceeds the threshold value, control operation of the furnace to adjust a flow rate of the air, a flow rate of the fuel, or both.

摘要： A water heater appliance includes an electronic mixing valve configured for adjusting a ratio of cold water from a cold water inlet conduit to hot water from a hot water outlet conduit at a mixed water outlet of the electronic mixing valve. A flow meter is mounted to the mixed water outlet conduit or the cold water inlet conduit. A controller is configured to calculate a flow rate of hot water through the hot water outlet conduit based on a temperature measurement from each of a mixed water temperature sensor, a cold water temperature sensor and a hot water temperature sensor and a flow rate measurement from the flow meter.
