CONDITIONING AND/OR HEATING PLANT AND PROCESS OF CONTROLLING THE SAME PLANT

摘要

A conditioning or heating plant and a process of controlling the plant, wherein plant comprises at least one circuit for distributing a carrier fluid, having a delivery line, a return line, and a plurality of channels directly or indirectly connected to the delivery line and return line and configured for supplying respective environments to be conditioned and/or heated, at least one heat treatment central group placed on the circuit. The plant has, for each of the channels, at least one respective heat exchange unit and at least one flow-rate regulator.

1. Process of controlling a conditioning and/or heating plant, said plant being of a type comprising:
at least one circuit configured for distributing a carrier fluid, having:
at least one delivery line of the carrier fluid,at least one return line of the carrier fluid, anda plurality of channels directly or indirectly connected to said delivery line and return line and configured for supplying respective environments to be conditioned and/or heated, at least one heat treatment central group placed on the circuit, wherein for each of said channels, the plant further comprises:
at least one respective heat exchange unit operating on each of said channels and configured for supplying a respective environment to be conditioned and/or heated,at least one flow-rate regulator operating on each of said channels and configured for regulating a flow-rate of a carrier fluid passing through the respective heat exchange unit, wherein each flow-rate regulator comprises at least one valve having a valve body exhibiting at least one inlet, at least one outlet connected by at least one passage which puts in fluid communication the inlet with the outlet, and at least one fluid intercepting element operating in said passage, said fluid intercepting element defining, cooperatively with the valve body, a fluid passage opening having a size variable as a function of positions taken by the fluid intercepting element in relation to the valve body,wherein said controlling process provides to:command the central group to regulate at least one general parameter selected among:
the hydraulic head imposed to the carrier fluid passing through the central group, the heating imposed to the carrier fluid passing through the central group, the cooling imposed to the carrier fluid passing through the central group, the flow-rate imposed to the carrier fluid on the delivery line,command the flow-rate regulator on each of said channels to impose a respective desired value of an operative parameter in relation to each channel wherein a respective flow-rate regulator is present,and wherein the controlling process comprises a hydraulic optimization cycle having at least the following steps:
commanding the central group for reducing the value of said general parameter, controlling each flow-rate regulator by increasing the size of said fluid passage opening.
