Description

[0001] The present invention relates to a method for controlling heating temperature in a room heating system,

The present invention relates to an efficient heating control method for each room heating system, and more specifically, by opening only one heating valve for each room and heating it, it is possible to maintain a maximum flow rate flowing into a pipe, The heating can be performed quickly and the installation cost can be reduced because a sufficient amount of heating can be achieved even if a boiler smaller than the entire heating load is installed. When heating is requested in several rooms simultaneously, It is possible to minimize the heating delay time between rooms by heating one room after setting the priority by using the car, and it is repeatedly performed until the current temperature of all the rooms requesting heating is higher than the set temperature, So that it can be satisfied.

Generally, a boiler is a boiler that uses oil, coal and gas as a fuel and burns it or uses heat of combustion and heat generated by supplying electricity to a heater to supply water to various heating facilities In the case of a domestic boiler, hot water is supplied to the piping installed on the floor of the room or the like, and the hot water is supplied to the hot water through a water pipe.

In recent years, a system has been developed and widely used for heating and supplying hot water to a plurality of rooms by using a single boiler. Such a boiler usually has one main remote controller and at least one wired or wireless sub remote controller And is controlled by a multi-remote control device, that is, a plurality of temperature control devices installed in each room.

At this time, the main remote controller is configured to be able to set various functions such as heating and heating temperature, and display the results thereof, and the sub remote controllers installed in other kitchens or other rooms can be operated for heating of the corresponding indoor space, So that the setting and the result thereof can be displayed.

Accordingly, the user can control the heating and the heating temperature of the entire room through the main remote controller, and control the heating and heating temperature of the corresponding room through the respective sub remote controllers.

In the cubic control system that controls the heating and hot water supply to a plurality of rooms using one boiler, there is a separate cubic temperature controller between the main body of the boiler and the multi remote controller (i.e., the main remote controller and the sub remote controller) Install it.

In each temperature regulator interlocked with the boiler having such a configuration, the heating temperature of the room is controlled by supplying or stopping the hot water to the pipe connected to the room by turning on / off the valve connected to each room to heat each room .

However, in the conventional each heating system, the heating effect can be obtained only by installing a boiler having a required capacity in the entire area of a place (i.e., rooms) where heating is desired.

In addition, even if a suitable boiler is installed in the heating area, if the heating area is wide, the heating water circulation pipe is long and circulation of the heating water is not easy, so that the heating effect can not be maximized.

In the case where the conventional room heating system having the above-described configuration is applied, when the rooms are heated at the same time, the above-described phenomenon occurs. Also, when heating is performed in several places, There is a problem in that the effect of heating is lower than that in the case of performing in one room and the desired heating effect can not be obtained.

That is, conventionally, when a heating signal is input to each of the room temperature control devices in each room, the respective valve driving device is immediately activated to heat the room, so that there is no heating problem when only a part is used in each heating system. When the heating request signal is inputted from all the temperature control devices of the system, all the valve driving devices are operated and all the rooms are heated simultaneously. Therefore, there is a problem that the time to rise the temperature is long. In addition, The capacity of the boiler is so small that heating problems are occurring.

In addition, when the heating effect of one room is taken into consideration by adjusting the amount of opening of the valves to each room so as to equalize the heating, the flow amount flowing therethrough is reduced, so that the heating time or effect tends to decrease.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an interior heating system to which the present invention is applied. FIG. 2 is a flow chart for explaining the method of the present invention. FIG. 3 is a flowchart A graph showing the temperature difference between the heating supply temperature and the heating return temperature.

As shown in FIG. 1, each of the heating systems to which the method of the present invention is applied includes a boiler 1 that operates largely as a heat source, a plurality of temperature control devices 2 corresponding to each number, A driving device 4 and an oven temperature controller 3.

At this time, the boiler 1 has a small capacity compared to the total area of the rooms to be heated, and is supplied to the inlet and the outlet of the controller 11 including the computing device 111 and the storage device 112, The temperature control device 3 has a configuration in which the circulation temperature detecting devices 12 and 13 and the flame detecting device 14, the fan driving device 15, the gas supply driving device 16 and the temperature adjusting device 17 are connected, And performs the function of providing the required number of heating units in each room under the control of the controller.

The outdoor temperature controller 3 is provided with a plurality of outdoor temperature control devices 2 and a plurality of outdoor temperature control devices 3 at an inlet and an outlet of a controller 31 having a computing device 311 and a storage device 312, The control unit 11 of the boiler 1 including the boiler 1 and the control unit 11 including the boiler 1 and the control unit 11 including the boiler 1, Function.

In addition, a plurality of outdoor temperature control devices 2 are installed in each of the rooms, respectively, so as to allow the user to select a heating or hot water mode, and to set a heating temperature and the like.

The plurality of valve units 4 are installed at the inlet or outlet of each heating pipe and are opened and closed in response to the output signal of the temperature controller 3 for each room and the heating water provided by the boiler 1 is heated And supplies the water to the pipe or automatically cut off the supplied water.

As shown in FIG. 2, the method according to the present invention applied to an open-angle heating system having the above-described configuration is as follows. First, each room temperature controller 2 installed in the entire room A in the room temperature controller 3, It is determined whether or not the heating request signal is inputted in any one of the outdoor temperature controllers 2.

As a result of the determination, if a heating request signal is input in any one of the outdoor temperature controllers 2 (S1), it is judged whether or not the outdoor temperature controller 3 Quot; is "0" (S2).

As a result of the determination by the respective temperature controller 3, if there is no round trip valve driving device 4 having a state of "on" (S4) the corresponding cubic valve driving device 4 corresponding to the output signal of the corresponding cubic temperature regulating device 3 and the boiler to the heating mode (S4) The heating operation is performed.

As described above, when the heating of one room A in which the heating request signal is inputted is started by the operation of the boiler, each of the room temperature controller 3 turns the pipe of the heating room A by one turn and is returned to the boiler It is determined whether the heating water return temperature T2 is higher than a value obtained by subtracting the constant temperature B from the heating water supply temperature T1 which is the hot water temperature of the boiler operating in the heating mode do.

The value of the constant temperature B used to keep the difference between the heating supply temperature T2 and the heating return temperature T1 within the constant temperature range in the cubic temperature controller 3 may vary depending on the capacity of the boiler, Water was circulated once through the pipe, and it was experimentally determined that it was set between about 15 ° C and 20 ° C.

As shown in FIG. 3, when the heating water is supplied to a specific room from a boiler, the temperature difference between the heating supply temperature (T2) and the heating water return temperature (T1) (B), which is set between " C " and " C ".

As described above, the heating water return temperature T2 returned to the boiler in the cubic temperature controller 3 is lower than the heating water temperature T1, which is the hot water temperature of the boiler operating in the heating mode, minus the constant temperature B If the heating water return temperature T2 is not greater than the value obtained by subtracting the constant temperature B determined at the heating supply temperature T1 as a result of the determination at step S5, The heating water return temperature T2 is determined by subtracting the constant temperature B determined at the heating supply temperature T1 from the heating water supply temperature T1 after the return water temperature T2 is greater than the heating water supply temperature T1 minus the constant water temperature B. (S6), it is judged whether or not the number of the respective valve driving apparatuses 4 currently waiting for heating is still "0" or less.

If the number of valves 4 for driving each room is not more than "0" (that is, if the heating request signal is not inputted in the other room A other than the one currently being heated) The heating set temperature Rts set by the user and the current temperature Rth of the room A in the room temperature control device 2 of the room A corresponding to the currently opened " (S7).

The current temperature of the room A corresponding to the respective valve driving device 4 during the current "on" operation using the detected heating set temperature Rts and the current temperature Rth of the room A If the present temperature Rth is not equal to or higher than the set temperature Rts (No in S8), it is determined whether or not the heating temperature of the room A is still higher than the set temperature Rts Since the set temperature Rts of the user is not reached, the individual temperature controller 3 returns to step S6 to determine whether or not the number of valves for each valve in the standby state is equal to or less than " 0 " .

However, if it is determined in step S8 that the present temperature Rth of the room A in which each valve driving apparatus 4 is on is greater than or equal to the set temperature Rts, (A) in which the respective valve driving apparatus 4 is in the ON state since the heating temperature of the room A is sufficiently higher than the user's set temperature Rts Off "(S9) of the respective valve driving apparatus 4 in the room where the current temperature Rth is equal to or higher than the set temperature Rts (that is, the room where the heating has been performed so far), and the heating operation of the boiler is also" (S10), the user of the specific room A determines whether he / she wants to heat the room, and enters the heating standby mode so as to perform heating if necessary.

On the other hand, when it is judged at S2 that the "ON" count of each valve driving device 4 stored in itself in the initial (S2) stage in the cubic temperature controller 3 is not "0" In other words, if the temperature of the room A is more than "1", the cubic temperature controller 3 recognizes that the boiler is already heating the specific room A, It is judged whether the water temperature T2 of the heating water is greater than the heating supply temperature T1 of the boiler operating in the heating mode minus the predetermined constant temperature B in operation S11.

 As a result of determining the value obtained by subtracting the constant temperature (B) determined from the heating supply temperature (T1) with respect to the heating return temperature (T2) of the specific room (A) in the heating operation in the respective room temperature controller (3) (T2) of the room is not greater than the value obtained by subtracting the predetermined constant temperature B from the heating supply temperature T1 (No in S11), the heating water return temperature T2 of the room is equal to the constant temperature B determined at the heating supply temperature T1. (S12) until the temperature of the room A becomes larger than the value obtained by subtracting the temperature of the room A from the temperature of the room A.

However, if it is determined in step S6 that the number of valves in each valve in the standby state is not equal to or smaller than "0" (No in S6), or the resultant heating return temperature T2 to be determined in step S11 (Step S11), the respective valve driving devices for the room A to which the heating has been performed previously are respectively turned " off "(S13).

In each of the temperature controllers 3 that have turned off the respective valve driving devices 4 for the room A that has been previously heated (S13), the heating of the user is subsequently requested but the heating is not performed The temperature control unit 2 sequentially receives the output signals of the respective room temperature control devices 2 corresponding to the respective valve driving devices 4 of the rooms waiting for heating and outputs the heating set temperatures Rts ) And the current temperature Rth of the corresponding room, and then sequentially calculates the temperature difference (Rty = Rts-Rth) between them (S14).

Then, in each of the room temperature controllers 3, it is judged whether or not the temperature differences (Rty) of the rooms currently waiting for heating are less than "0" (that is, If the temperature differences (Rty) of the rooms currently waiting for heating are not less than "0" (that is, if the current temperature is lower than the set temperature in either room and both temperature differences are higher than "0" The room having the largest temperature difference Rty is selected (S16).

Subsequently, in each of the room temperature controllers 3, it is determined that the temperature difference (Rty) among the plurality of rooms to be heated is the largest, so that only the respective valve driving device 4 of the selected room A is turned "on" The process returns to the step S4 to turn the heating room T2 back to the room A until the heating return temperature T2 of the room A becomes larger than the value obtained by subtracting the constant temperature B from the heating supply temperature T1, The next step is repeated until the current temperature reaches the set temperature.

However, if it is determined in S15 that the temperature differences Rty in the rooms waiting for the current heating are all less than 0 in the room temperature controller 3 as a result of the judgment in S15, If the temperature difference (Rty = Rts - Rth) between them is lower than " 0 "(Yes in S15), it is recognized that the heating for all the desired rooms A is completed, (S10). Then, the user of the specific room (A) judges whether he or she desires to heat the room, and enters the heating standby mode so that heating can be performed if necessary.

As described above, according to the present invention, if a heating request signal is sent to a specific room among a plurality of rooms, it is checked whether there is a room currently heating. If there is no room heating, Open heating to check whether the difference between the heating supply temperature (T1) for heating and the heating return temperature (t2) is within a certain range, make minimal heating, check whether there is a heating standby room, If the current temperature is higher than the set temperature, the current valve driving device (4) is closed and the current temperature of all the rooms requesting heating is lower than the set temperature If it is confirmed that it is high, if the heating is stopped, the boiler can be stopped because the heating can be performed at a desired temperature quickly, It is possible to use the boiler with small capacity compared to the total area of the desired rooms, thereby reducing the price burden of the consumer, and it is possible to heat the boiler at a required temperature for each room with a small capacity boiler.

If there is another room currently being heated when there is a heating request signal in a specific room, it is checked whether the difference between the heating supply temperature (T1) and the heating return temperature (T2) of the room being heated is within a certain range or not, (Rth) between the current temperature (Rth) and the set temperature (Rts) in the waiting state in the state of requesting heating after the heating is requested, so that the room having the largest temperature difference can be selected to be heated preferentially, It is possible to significantly improve the satisfaction and, in particular, to improve the reliability of the heating and heating system of the interior heating system itself.
