(54) Method for regulating the delivery temperature of a service fluid in output from a refrigerating machine


(57) In a refrigerating machine (3) for an air-conditioning system (1), which is equipped with one or more fan coils (2) and a hydronic circuit (15) having a delivery branch (16) for the circulation of a service fluid (5) from the refrigerating machine (3) to the fan coils (2) and a return branch (17) for the return of the service fluid (5) in input to the refrigerating machine (3), the compressor (12) of the machine (3) is switched on and off (102-105) as a function of a measurement of the delivery temperature (TDLV) such that the same delivery temperature (TDLV) converges to a set point temperature (TSET), and this set point temperature (TSET) is adapted (106-115) to an estimate of the cooling/heating load (FL) of the hydronic circuit (15).
