摘要:
A method to control a carrier fluid through a service line (5) of a conditioning and/or heating system (1). The service line includes a heat exchange unit (7), a flow regulator (8), temperature sensors (9; 9a, 9b) detecting a temperature difference (ΔTi) between the carrier fluid in a first section (5a) of the service line (5) upstream of said heat exchange unit (7) and carrier fluid in a second section (5b) of the service line (5) downstream of the same heat exchange unit (7). The method includes calculating a value assumed by a control parameter (Pc) which is a function of at least one or more values assumed by the temperature difference in the transition of the flow regulator from a first to a second operating condition, for then determining whether the value of the control parameter (Pc) is higher than a threshold (S).

摘要:
Control process of a thermal plant including a distribution circuit for a carrier fluid having a delivery line and a return line, a central thermal treatment group placed on the circuit, and channels, each of which is hydraulically interposed between the delivery line and the return line to serve respective environments. For each of the channels, the plant includes a respective exchange unit, a flow regulator to regulate a flow rate of carrier fluid through in the respective channel, an ambient temperature detector, a temperature detector of the carrier fluid for detecting a delivery temperature of the carrier fluid in each channel, and a return temperature of the carrier fluid in each channel. The process also includes a thermal optimization procedure as a function of ambient temperature, delivery temperature and return temperature of the carrier fluid.
