摘要： A hot water supply system 400 comprises a cold water inlet 402 coupled to a valve 404 which determines the degree of flow in a first path 406 and a second path 408. The first path comprises an Energy Storage Arrangement including a heat exchanger 410 which can heat the water from the inlet. The second path includes an electrical heater 422 which can also heat water from the inlet. The two paths each include a respective flow sensor 416, 428 and the paths re-join before providing an outlet 420 from the supply system via a temperature sensor 418. A controller 430 controls the valve 404 and the electrical heater 422 in response to the sensor signals to provide hot water at a desired temperature using a suitable proportion of stored energy and electrical energy. By charging the Energy Storage Arrangement using a heat pump, an economical and responsive hot water supply system is provided.

摘要： A heated water recirculation system includes a water heater having a water inlet and a water outlet. The heated water recirculation system further includes a flow detector positioned to detect inflow water flowing into the water heater through the water inlet. The heated water recirculation system also includes a controller configured to control operations of a recirculation pump based on a detection of the inflow water flowing into the water heater through the water inlet. The water heater is configured to provide heated water through the water outlet, and the recirculation pump is configured to circulate the heated water through the heated water recirculation system.

摘要： A method for operating and/or monitoring an HVAC system (10), in which a medium circulating in a primary circuit (26) flows through at least one energy consumer (11, 12, 13), the medium entering with a volume flow (φ) through a supply line (14) into the energy consumer (11, 12, 13) at a supply temperature (Tv) and leaving the energy consumer (11, 12, 13) at a return temperature (TR) via a return line (15), and transferring heat or cooling energy to the energy consumer (11, 12, 13) in an energy flow (E). A control unit (21) adaptively operates the system by empirically determining the dependence of the energy flow (F) and/or the temperature difference ΔT between supply temperature (Tv) and return temperature (TR) on the volume flow (φ) for the energy consumers (11, 12, 13) in a first step, and by operating and/or monitoring the HVAC system (10) according to the determined dependency or dependencies in a second step.

摘要： The invention relates to a method for operating and/or monitoring an HVAC system (10), in which medium circulating in a primary circuit (26) flows through at least one energy consumer (11, 12, 13), the medium entering with a volume flow (φ) through a supply line (14) into the energy consumer (11, 12, 13) at a supply temperature (TV) and leaving the energy consumer (11, 12, 13) at a return temperature (TR) via a return line (15), and transferring heat or cooling energy to the energy consumer (11, 12, 13) in an energy flow (E). A considerable improvement in the operating behavior of the system is achieved by empirically determining the dependence of the energy flow (E) and/or the temperature difference (AT) between supply temperature (TV) and return temperature (TR) on the volume flow (φ) for the energy consumers (11, 12, 13) in a first step, and by operating and/or monitoring the HVAC system (10) according to the determined dependency or dependencies in a second step.

摘要： The present invention relates to methods for operating and controlling flow control systems. The method includes sensing an actual medium flow through a pipe part and outputting an electrical signal indicative of the sensed actual medium flow; comparing the sensed medium flow with a set medium flow and outputting a control signal; using an orifice adjusting system to adjust an adjustable orifice in a pipe part in response to the control signal; and performing a correction of a characteristic curve. The method can include setting an upper limit for medium flow to Vmax wherein Vmax is less than a maximum medium flow.

摘要： A conversion factor learning unit successively updates a temperature conversion factor by learning a performance ratio of an output heat quantity with respect to an input scale number corresponding to a requested heat quantity generation to a hot water supply apparatus. The temperature conversion factor learned by the conversion factor learning unit is reflected in arithmetic operation of an FF scale number by a feedforward control unit and arithmetic operation of the FB scale number by the feedback control unit. An integral control in the feedback control unit is preferably turned off.

摘要： At the time of starting a hot water discharge operation, a controller determines whether the first operation was made after the power source is switched on in S1, and the controller determines whether 5 minutes have passed after the previous operation in S2. When the first operation was not made or 5 minutes have lapsed after the last operation, the controller determines whether a difference between a detected temperature acquired by a thermistor and a preset temperature is more than 10° C. in S3. When a temperature difference is more than 10° C., a water flow rate servo is set at a position where a flow rate of flowing water is reduced from a determined flow rate by a predetermined amount in S4, and the controller performs a temperature control of discharged hot water in S8.

摘要： A water heating system, in which water from a relatively low pressure closed-loop heated water circuit flows through a heat exchanger, through which a relatively high pressure mains cold water feed also flows, to supply both a demand for hot water from the high pressure circuit and/or a demand from heated water consumers such as radiators or showers, is characterised by the feature that the low pressure heated water always flows first through the heat exchanger before supplying any of the heated water consumers; or by the feature that flow restrictors are incorporated into the heat exchanger circuit infeed; or both.
