The present disclosure relates to systems and methods for controlling heating, ventilation, cooling, and potable hot water delivery. The method performed by a control unit includes receiving at least one input signal indicating thermal energy requirements associated with an Air Conditioning and Potable Hot Water (ACPH) system. In response to the at least one input signal, the method includes generating an operating scheme for at least generating thermal outcome corresponding to the thermal energy requirements based on the State of Charge (SoC) of a thermal store, parameters, and operating factors. Further, the method includes selectively operating the thermal store, and the plurality of thermal energy systems based on the operating scheme for supplying the thermal outcome corresponding to the thermal energy requirements. Furthermore, the method includes supplying the thermal outcome corresponding to the thermal energy requirements for at least space conditioning and delivery of potable hot water.

Systems and methods for controlling heating, ventilation, cooling, and potable hot water delivery

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.

Control systems and methods for managing rate of heat delivery in hydronic systems

The present disclosure provides methods and systems for tracking temperature profile of water in a hot water storage tank. The method performed by a control unit includes monitoring flow of water at one or more inlets and one or more outlets included in the tank to determine current locations of a plurality of water layers within the tank. The plurality of water layers changes corresponding positions within the tank based on water entering within and exiting from the tank. The method includes receiving a series of temperature values measured at a series of time instances from at least one temperature sensor mounted to the tank. The method includes electronically generating a temperature profile of the tank based at least on the current locations of the plurality of water layers and the series of temperature values.
