Method, controller and system of controlling thermal power transfer through a thermal energy exchanger

Abstract

A method of controlling a thermal power transfer of a thermal energy exchanger (80) of an HVAC system (1), the method comprising: receiving, by a controller (10), a setpoint thermal power transfer (Power SP); measuring, by a flow sensor (52), a measured flow of fluid (ϕact) through the thermal energy exchanger (80); determining, by the controller (10), an estimated thermal power transfer (Power EST), using the measured flow of fluid (ϕact) and a defined flow rate to delta-T mapping; comparing, by the controller (10), the setpoint thermal power transfer (Power SP) and the estimated thermal power transfer (Power EST); and regulating, by the controller (10), the flow (ϕact) of the fluid (W) through the thermal energy exchanger (80) based on the comparing.
