Abstract (en)

[origin: EP2000754A2] In a refrigerating machine (3) for an air-conditioning system (1), which is provided with one or more fan coils (2) and with a hydronic circuit (15) having a delivery branch (16) for circulation of a service fluid (5) from the refrigerating machine (3) to the fan coils (2) and a return branch (17) for return of the service fluid (5) at inlet to the refrigerating machine (3), via a pair of temperature sensors (21, 22), a delivery temperature (TDLV) of the service fluid (5) at outlet from the refrigerating machine (3) and a return temperature (TRET) of the service fluid (5) at inlet to the refrigerating machine (3) are measured, and the thermal load (FL) of the hydronic circuit (15) is estimated (106, 107, 109, 111) by processing, via a Kalman filter, the measurements of the delivery temperature (TDLV) and return temperature (TRET).
