INDIVIDUAL ROOM CONTROL SYSTEM PROVIDED WITH FLOW LIMITING VALVES, AND FLOW LIMITING VALVE PROVIDED THEREIN

WIPO Patent Application WO/2012/128442

A1

The object of the present invention is to provide an individual room control system provided with flow limiting valves, which is adapted to prevent the cavitation-induced noise that occurs in heating pipes when the heating of one or some of a plurality of rooms is stopped, as a result of the intensive supply of heating water to the rooms that are being heated, and is adapted to allow heating costs to be economised upon and at the same time the system structure to be simplified such that the system is inexpensive to implement. In order to achieve this object, the individual room control system equipped with flow limiting valves of the present invention comprises: a temperature adjusting unit for setting the heating temperatures in individual rooms; individual room valves for adjusting the volume of supply of heating water supplied to the individual rooms in accordance with the heating loads in the individual rooms; flow limiting valves which are provided on the heating-water inlet sides of the individual room valves and limit the maximum volume of supply of the heating water supplied to the individual room valves; and a control unit for controlling the drive of the individual room valves on receiving input in the form of a signal which is set from the temperature adjusting unit.
