摘要： The present disclosure provides a method for operating the hydronic system, which includes monitoring, by a control unit, a volume of hot water in a hot storage tank via a first set of flowmeters and a volume of chilled water in a cold storage tank via a set of second flowmeters. A first outlet temperature of the hot water is monitored by the control unit, via a first temperature sensor and a second outlet temperature of the chilled water via a second temperature sensor. A heat pump unit is operated by control unit, for recharging the hot water and the chilled water within the hot storage tank and the cold storage tank respectively. The heat pump unit is operated when a respective predetermined limit reaches for at least one of the volume of the hot water, the volume of the chilled water, the first outlet temperature and second outlet temperature.

摘要： 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.

摘要： Embodiments of the present disclosure provide systems and methods for determining temperature profile associated with a thermal storage tank of a hydronic system. The method performed by a control unit includes monitoring a flow rate and a temperature of a volume of hot water and a volume of cold water entering a thermal storage tank via a set of flowmeters and a set of temperature sensors, respectively. The method includes determining a current location of plurality of water layers in the thermal storage tank. The method further includes computing an average temperature value of the at least the hot water and the cold water withdrawn from the thermal storage tank. The method includes generating a temperature profile of the thermal storage tank based at least on the current location, the flow rate and the temperature of the hot water and the cold water, and the average temperature value.
