Embodiments of the present disclosure provide a system for disinfecting water for hydronic space conditioning and domestic hot water. The system includes a thermal storage tank, a disinfecting device and a control unit. The control unit monitors an outlet temperature of water exiting the thermal storage tank. Further, the control unit calculates a temperature difference between a temperature threshold limit associated with the disinfecting device and the outlet temperature. The control unit transmits a first signal to the disinfecting device when the temperature difference is a positive value. The first signal operates the disinfecting device in the activation mode for heating the water to provide anti-bacterial sanitation. The control unit transmits a second signal to the disinfecting device for deactivating the disinfecting device when the temperature difference is a negative value. The sanitized water from the disinfecting device is used for conditioning an enclosure and a domestic hot water.

The present disclosure pertains to a system configured to prepare and use prediction models for classifying images. Some embodiments may: obtain, via a system return temperature sensor, a system return temperature; obtain, via an appliance return temperature sensor, an appliance return temperature; and responsive to a determination that the appliance return temperature is greater than the system return temperature by at least a first threshold amount, decrease, via a hardware processor, a speed of the appliance pump.

The heat exchanger inlet is connected to the feed conduit of the district cooling grid; and the heat pump inlet is connected to the return conduit of the district cooling grid and to the heat exchanger outlet.

An external control unit to be connected between a power source and an electrically driven pump to act as a smart switch to convert a “dumb” pump into a smart pump. The control system of this invention comprises a microcontroller-operated switch, located between the power source and the pump, or other fluid flow control device to be operated by electricity, and which can be programmed to record usage data of, e.g., hot water, by the household; it sets up the operating times in accordance with such usage. A temperature sensor is connected to the microcontroller to sense a temperature change, in a hot water system is turned on, by measuring an increase in temperature to indicate flow through the hot water pipe, and to record such data. This will determine, in the context of a hot water system, when the pump should be activated to bring up hot water.

A heat emitting radiator for use in a fluid circuit containing coolant therein, and which can generate substantial amounts of heat to heat larger spaces, such as in a home or business, while utilizing minimal power to run, and which can be utilized in various implementations and configurations. The radiator can be selectively activated or de-activated by, for example, a cell phone or the like whereby the fluid circuit in the radiator can be monitored for time of use, temperature and cost of use.

The present invention relates to a local thermal energy consumer assembly and a local thermal energy generator assembly to be connected to a thermal energy circuit comprising a hot and a cold conduit. The local thermal energy consumer assembly is selectively connected, via a pump or a valve to the hot conduit. The local thermal energy generator assembly is selectively connected, via a pump or a valve to the cold conduit. The use of either the valve or the pump is controlled by determining a local pressure difference between heat transfer liquid of the hot and the cold conduits.

A fluid transportation network (1) comprises a plurality of parallel zones (Z1, Z2), fed by a common supply line (L), with a regulating zone valve (V1, V2) in each zone (Z1, Z2) for regulating a flow of fluid (ϕ.sub.1, ϕ.sub.2) through the respective zone (Z1, Z2). A processing unit (RE) receives valve positions (pos.sub.1, pos.sub.2) of the regulating zone valves (V1, V2) and determines and sets an adjusted valve position for a line valve (VE) arranged in the supply line (L), depending on the valve positions (pos.sub.1, pos.sub.2) of the regulating zone valves (V1, V2). A processing unit (RE) further receives a measurement of a total flow of fluid (ϕ.sub.tot) through the supply line (L) and determines and sets adjusted valve positions for the regulating zone valves (V1, V2), depending on the measurement of the total flow of fluid (ϕ.sub.tot) through the supply line (L).

One embodiment of present disclosure discloses an electrode boiler system including a body portion formed to receive the electrolyzed water therein, an electrode portion having a plurality of electrodes disposed in the body portion, wherein at least a portion of the plurality of electrodes contacts the electrolyzed water within the body portion, a first flow path portion through which the electrolyzed water in the body portion flows out and moves after heated by a current applied to the electrode portion, a second flow path portion through which the electrolyzed water flows into the body portion and which is formed to be spaced apart from the first flow path portion, and a control portion to control the current applied to the electrode portion.

The present disclosure provides a method for controlling rate of heat delivery in a hydronic system, which includes receiving, by a control unit, at least a first temperature, a second temperature from two spatially separated points in the hydronic system and a flow rate. The two spatially separated points correspond to inlet of heat transfer device and outlet of heat transfer device. The method also includes calculating at predefined interval, by the control unit, an actual rate of heat delivery to the heat transfer device based on flow rate and temperature difference between the two spatially separated points. The control unit determines heat delivery rate difference between actual rate of heat delivery and target rate of heat delivery. The control unit adapts flow rate of fluid into inlet of heat transfer device based on heat delivery rate difference to maintain target rate of heat delivery in heat transfer device.
