Abstract
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.
