Device for control room temperature of each room adapted to heating environment and its method

Abstract

The present invention relates to a device for control room temperature of each room adapted to heating environment that allows a temperature control system to be adapted by itself to heating environment (quantity of heat of a heating source, magnitude of load, difference between setting temperature and room temperature) by reflecting the changes in the heating environment and data obtained by previous heating into the control, and reduces unnecessary energy consumption by controlling the quantity of heat of a boiler at the minimum required level. In order to achieve the above, the present invention includes: a boiler that creates combustion heat, exchanges the heat with heating water, and then circulates the heating water through each heating load; one or more heat pipes that are provided to heating positions; heating control valves that is provided to allow or stop the circulation of the heating water through the heat pipes; an individual room controller that makes it possible to set interior temperature for each room, and converts the set interior temperature into return water control temperature and then outputs the return water control temperature; a valve controller that controls quantity of heat of the boiler by integrating the return water control temperature transmitted from one or more individual room controllers and outputs a control signal to the boiler to maintain the highest return water control temperature of the return water control temperature required by the individual room controller; and a valve actuating unit that turns on/off the valve control valve according to the control signal of the valve controller.

1 . A device for control room temperature of each room adapted to heating environment, comprising:
 a boiler that creates combustion heat, exchanges the heat with heating water, and the circulates the heating water through each heating load;   one or more heat pipes that are provided to heating positions;   heating control valves that is provided for the heat pipes to allow or stop the circulation of the heating water through the heat pipes;   an individual room controller that makes is possible to set interior temperature for each room, and converts the set interior temperature into return water control temperature and then outputs the return water control temperature;   a valve controller that controls the quantity of heat of the boiler by integrating the return water control temperature transmitted from one or more individual room controllers and outputs a control signal to the boiler to maintain the highest return water control temperature of the return water control temperature required by the individual room controller; and   a valve actuating unit that turns on/off the valve control valve according to the control signal of the valve controller.   
     
     
         2 . A method of controlling room temperature of each room adapted to heating environment, comprising:
 outputting return water control temperature of each room after converting interior temperature set by a user through an individual room controller into the return water control temperature of each room;   controlling the quantity of heat of a boiler to maintain the highest control from the return water control temperature of each room received by the valve controller;   multiplying a value, which is obtained by subtracting return water control temperature of a room to be controlled from the return water control temperature of the boiler, by a control calibrating constant, and then determining an object value for control of the interior temperature by subtracting the above value from the set interior temperature;   performing heating by opening a heating control valve until the present interior temperature increases higher than the valve closing temperature, which is set in advance, when the present interior temperature is lower than the valve opening temperature that is set in advance, in the individual room controller;   detecting a difference in temperature between the temperature when the interior temperature of each room is higher than the valve opening temperature in the heating, in the performing of heating, and the temperature when the interior temperature of each room is lower than the valve closing temperature in stopping the heating; and   controlling opening/closing of the heating control valve at a renewal object value for control which is obtained by reflecting the difference in temperature to the return water control temperature of the previous control cycle, before performing again heating, as the present interior temperature becomes lower than the valve opening temperature that is set in advance.   
     
     
         3 . The method of controlling room temperature of each room adapted to heating environment according to  claim 2 , wherein the return water control temperature of the boiler is set to the highest return water control temperature of the return water control temperature of each room, in the performing of heating.
