Abstract
A heat control system designed to control individual radiators in a heating system where there is only one boiler supplying steam, or one heated fluid source such as a utility steam supply, and where there is no separate condensate return line; each radiator or riser or both may be individually controlled by devices at and external of the radiator without the need for reconstructing the heating system itself or inserting any mechanical device within the system which will block return of condensates; there is an on-off control valve between the radiator and its vent valve and controllable preferably by a room thermostat; additional fuel saving controls may include a device that is responsive to the radiator becoming heated to a desired level or internal pressure in the radiator to provide an additional control for the control valve.
Claims4
A heating system comprising:
- a plurality of radiators (10), each having an inlet end and an outlet (12);
- a source of steam (G);
- conduits (100, etc.) connecting said source of steam to said inlets of all said radiators;
- each said radiator having a vent valve (B) at its said outlet, such that steam from said source of steam passes through said connecting conduits and drives any air in each said radiator through its said vent valve;
- means (15) for closing each said vent valve when steam in the radiator reaches said vent valve;
- an additional vent valve (C) for each said radiator connected to transmit venting flow from the respective radiator to the respective aforementioned vent valve (B);
- an on-off control for each said additional vent valve for permitting individual control of its said radiator comprising:
- a passage (21) from a said radiator to its said additional vent valve;
- a valve means (24) located in each said passage and operable to open said passage and to close said passage to open or close said additional vent valve;
- said valve means when closed, blocking access to its said additional vent valve from its said radiator and thereby preventing passage of air from said radiator through said first mentioned vent valve (B), thereby blocking the entry of steam in said radiator;
- said valve means when open, permitting the steam to drive air through both said vent valves, thereby permitting steam to enter said radiator;
- said valve means comprising means (25) applying a closing bias on said additional vent valve independently of room temperature and further comprising electrical means (31) to operate said valve to an open position;
- and a room thermostat (D) located in the area in which a said radiator is positioned;
- electrical connection means (35, etc.) from said room thermostat to said valve electrical means for operating said valve and causing said valve to open at a predetermined temperature;
- means including said room thermostat (D) for controlling said steam source (G) to cause steam to enter said conduits and to stop additional steam from entering said conduits;
- said latter means comprising transmitting means (E) for transmitting a signal from said room thermostat to said steam source for controlling the steam source to start the entry of steam into said conduits at said predetermined temperature and to halt entry of steam into said conduits at another, higher, predetermined temperature;
- whereby when said room thermostat causes a signal to halt the entry of steam into said conduits, the said electrical means is deenergized thereby causing said additional vent valve to close.
