Technical Field
[1] The present invention relates to a device for control each temperature of warm circulation water of each room control system that can control temperature of the floor of each room at a similar level, in which each room is equipped with a plurality of heat pipes. More particularly, the present invention relates to a device for control each temperature of warm circulation water of each room control system that makes it possible to maintain similar level of temperature throughout the floor of one room by controlling the opening/closing of a valve that controls the circulation amount of heating water in each heat pipe by detecting the temperature of heating water in a plurality of heat pipes provided in one room. Background Art
[2] In general, heating apparatuses are apparatuses that burn fuel therein, such as gas or oil, using a boiler, heat heating water using combustion heat created by the combustion, and then heat the inside of a room by circulating the heated water through heat pipes provided in the floor, etc. in the room, or supply hot water using the heating water.
[3] As a control method for maintaining the interior temperature at user-desired setting temperature In these heating apparatuses, there are a method of turning on/off a heating apparatus according to a higher or lower level of the interior temperature than the setting temperature after measuring the interior temperature and comparing it with the setting temperature, a method of turning on/off a heating apparatus according to a higher or lower level of the temperature of water in a heat pipe than setting temperature after measuring the temperature of the water in the heat pipe and comparing it with the setting temperature, and a method of repeatedly operating and stopping a heating apparatus for a time set by a user.
[4] The method of controlling the heating temperature while measuring the interior temperature in the above methods turns on/off the heating apparatus by comparing the temperature set by the user with the interior temperature measured by a temperature sensor attached to an interior temperature controller, in which the interior temperature is increased while the heating water exchanges heat with the floor and the floor exchanges heat with the interior air, such that the interior heating is achieved.
[5] As this method uses a way of adjusting the interior temperature by increasing the temperature of the floor, it has a problem in that the temperature of the floor may ex- cessively increase until the interior temperature reaches the setting temperature, whereas it takes the interior temperature a long time to drop after once increasing above the setting temperature, such that the temperature of the floor may excessively decrease while the interior temperature drops.
[6] Further, the method of controlling the temperature according to the temperature of return water in a valve also has a problem in that non-uniformity of temperatures that are different depending on positions may occur in a room equipped with a plurality of valves having different loads unless each of heat pipes can be individually controlled. Disclosure of Invention Technical Problem
[7] The related art had a problem, as described above, in that users preferring life in an ondol room was inconvenienced due to a phenomenon in which the temperature of the floor excessively increases or decreases by control based on the interior temperature in an individual heating and temperature differences are generated according to positions even in one room, such that there was inconvenience in practical use.
[8] The present invention was designed to overcome the above problems, and it is an object of the present invention to provide a device for control each temperature of warm circulation water of each room control system that can considerably reduce temperature differences according to positions in a room by individually controlling valves on the basis of set return water temperature, in order to resolve a problem of when temperature of the floor becomes different according to loads of heat pipes, while using a boiler configured to prevent unnecessary waste of energy by controlling the operation of the boiler, which is a heat source, at the quantity of heat required according to return water temperature for each room. Technical Solution
[9] In order to achieve the above objects of the present invention, a device for control each temperature of warm circulation water of each room control system, includes: a boiler that creates combustion heat, exchanges the heat with heating water, and then circulates the heated water through a heating load; one or more heating loads having a plurality of heat pipes for one room; heating control valves that are provided for the heat pipes, respectively, to allow or stop the circulation of the heating water through the heat pipes; return water temperature detecting sensors that detect temperature of return water in the heat pipes; an individual room controller that is able to set temperature of the heating water and calculates needed quantity of heat by comparing the set temperature of the heating water with the return water temperature; a valve controller that receives the return water temperature from the return water temperature detecting sensors, transmits the return water temperature to the individual room controller, and outputs control signals by determining independent turning on/off of the heating control valves in order to maintain the same return water temperature for the same heating loads; and a valve actuating unit that turns on/off the heating control valves in response to the control signals of the valve controller.
Advantageous Effects
[10] It is possible to satisfy a user who had been familiar with ondol by maintaining constant floor temperature by applying a method of controlling return water temperature that is suitable for adjusting the temperature of the floor in an each room control system, and to expect energy saving as compared with an each room control system, which cannot control a heat source (boiler), by controlling a boiler to have quantity of heat required for each room. Further, even if a plurality of valves having different loads are provided in one room, it is possible to prevent non-uniformity of temperature according to position in one room by individually controlling the valves on the basis of set return water temperature. Brief Description of Drawings
[11] FIG. 1 is a view illustrating the configuration of the present invention.
Best Mode for Carrying out the Invention
[12] The configuration and operation of a preferred embodiment of the invention is described hereafter in detail with reference to the accompanying drawing.
[13] A boiler 10 creates combustion heat by burning gas or oil in a combustion chamber, exchanges the heat with heating water in a heat exchanger, heats each room by supplying the heating water to heat pipes (individual room heating load) 20:20A, 2OB, 2OC, 2OD provided in each room through a heating water discharge pipe 60, returns the heating water of which the temperature have dropped to low temperature through a heating water return pipe 70, heats again the heating water to high temperature by exchanging heat with combustion heat, and then supplies the heating water to each room heating load 20, which is repeated. The fuel, such as gas or oil, which is supplied to create combustion heat while burning in the boiler 10 is supplied, for example, through a proportional control valve (not shown), such that it is possible to adjust the quantity of heat created in the boiler 10 by adjusting the amount of supplied fuel.
[14] The heating load 20 may be divided into heating loads 2OA, 2OB, 2OC, 2OD having different sizes for each room and the individual room loads 2OA, 2OB, 2OC, 2OD may also be each composed of one or more heat pipes as shown in the figure.
[15] Heating control valves Vl ~ V8 that open/close the heat pipes to circulate or stop the heating water are provided to the heat pipes of the heating load 20, respectively. The opening amount of heating control valves Vl ~ V8 is adjusted by a valve actuating unit 40 that is controlled by a valve controller 30. [16] Further, return water temperature detecting sensors Sl ~ S 8 that each detect return water temperature in the heat pipes are disposed at the heating water return points of the heat pipes, respectively, that is, the position right before the heating water returns to the boiler 10 through heating points in each room. The return water temperature detected by the return water temperature detecting sensors Sl ~ S8 is transmitted to individual room controllers 50: 50A, 50B, 50C, 50D through the valve controller 30.
[17] The individual room controller 50 has a function of setting user-desired interior temperature for each room, such that the individual room controller 50 is composed of individual room controllers 50A, 50B, 50C, 50D which are disposed in the rooms, respectively. The individual room controller 50 according to this embodiment is c onfigured to be able to set the interior temperature by setting the return water temperature of the heating water. Further, the individual room controller 50 calculates the needed quantity of heat by comparing the return water temperature set by the user with the detected return water temperature transmitted from the return water temperature detecting sensors Sl ~ S8, independently determines the opening/closing of the heating control valves Vl ~ V8, and then outputs the determined results to the valve controller 30.
[18] The valve controller 30 controls the quantity of heat of the boiler 10 by integrating information on the quantity of heat transmitted from the individual room controllers 50A, 50B, 50C, 50D, and controls turning on/off of the heating control valves Vl ~ V8 through control of the valve actuating unit 40.
[19] In the example shown in the figure, for the heating load 2OA, three heat pipes are provided in one room and the valves Vl ~ V3 are provided for the heat pipes, respectively, to be independently controlled. That is, when user-desired interior temperature (return water temperature) is set in the heating load 2OA through the individual room controller 50A by a user, there may be a difference in each heat pipe. Therefore, the individual room controller 50A receives return water temperature in the heat pipes from the return water temperature detecting sensors S 1 ~ S3 while receiving the quantity of heat of the boiler from the valve controller 30, and determines and controls the opening/closing time of the valves Vl ~ V3. As a result, it is possible to maintain uniform returning temperature for the heat pipes, that is, to maintain uniform temperature throughout the floor.
[20] Although the heat pipes, in which the heating load 2OA has three lines of heat pipes, the heating load 2OB has two lines of heat pipes, the heating load 2OC has one line of heat pipe, and the heating load 2OD has two lines of heat pipes 2OD, is exemplified in the embodiment shown in the figure, the present invention is not limited thereto and may be equally applied to configurations having a various types of heat pipes for each room, without departing from the spirit of the present invention. Industrial Applicability
[21] As described above, the present invention can make it possible to maintain similar temperature throughout the floor in a room when it is applied to an each room control system including a plurality of heat pipes for one room.
