Description

Automatically controlling method for heating temperatures in each room in each heating system}

The present invention relates to a method for automatically controlling the heating temperature of each room in each heating system. More specifically, the heating temperature automatic control function is automatically installed by a user by installing a heating temperature automatic control key in the central room cone provided in each heating system. When set, the user can provide a comfortable environment by maintaining the temperature of the same room (29-36 ℃ or 39-46 ℃) regardless of the season of 365 days a year, even if the user does not set a special setting. It is invented to significantly save energy by controlling the temperature of tapping water.

Generally, a boiler is used to heat water by using combustion heat and heat generated by burning it using fuel, coal or gas as fuel, or supplying electricity to a heater, and supplying hot 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 is used for supplying hot water through a water pipe or the like.

On the other hand, in buildings with several rooms, such as inns, test houses, and studios, each room is equipped with a separate room temperature controller, an energy-saving automatic heating system that separately controls the room temperature. Each room is equipped with a heating system.

Looking at the configuration of each room heating system, such as a heating source or individual boiler, each room controller and several room cones installed in each room, the living room installed in each room to monitor the status of hot water use, including the heating conditions of each room A central room cone for heating control of a room (for example, a living room) in which the room cone is installed, a valve for controlling the number of heating in each room (ie, a heating water supply control valve) and a valve driver for controlling opening and closing of the valve Doing.

However, in the case of the conventional proportional control system of each heating system, only the temperature balance control of each room is focused, and there is no control method after the temperature balance of each room.

In this case, when the tap water temperature of the heat source or boiler including the district heating system is fixed, the temperature of the room is controlled for one year because the temperature at the point where the temperature of each room is balanced in the proportional control system depends largely on the environment (seasonal, etc.). In order to keep constant throughout, there is a hassle for the user to adjust the temperature of the tap water (heating water) manually to adjust the temperature of the room.

The present invention has been made in order to solve such a conventional problem, the heating temperature automatic control key is installed in the central room cone provided in each room heating system by the user heating mode in the heating mode through the automatic control key When the automatic adjustment function is selected, the temperature of the same room (29 ~ 36 ℃ or 39 ~ 46 ℃) is maintained regardless of the season of 365 days a year, so that the temperature of the room is 29 ~ 36 ℃ or 39 ~ even if the user does not set it. Since it maintains 46 ℃, it can provide a more comfortable environment for the user and can automatically adjust the temperature of the tap water of the boiler, which not only saves a lot of energy, but also greatly improves the reliability of using the product.

(t1) is maintained, and the return temperature of each room corresponding to the valve which is 100% open every second time (t2) afterwards is measured and When the difference from the stationary position is within the saturation judgment temperature range (± X ℃), the valve opening amount of the room with the lowest return temperature is maintained at 100%, and the opening amount of the remaining valves corresponds to the return temperature difference for each room.

If the minimum value (Tmin) is higher, the tapping setting temperature (Tset) of the heat source or boiler is lowered by one step to a preset temperature range. Returning to the step; characterized in that consisting of.

At this time, if the average return temperature of each room is less than the first limit temperature (Y1 ℃) determining whether the average return temperature of each room is less than the predetermined second limit temperature (Y2 ℃); Maintaining the current state if the average return temperature of each room is greater than or equal to the second limit temperature (Y2 ° C.); Determining whether the tapping temperature Tout of the heat source or the boiler is at or below the maximum value Tmax if the average return temperature of each room is less than the second limit temperature (Y2 ° C); As a result of the above determination, if the maximum value (Tmax) is maintained, the tapping set temperature (Tset) of the heat source or the boiler is maintained, and if it is below the maximum value (Tmax), the tapping setting temperature (Tset) of the heat source or boiler is increased by one step to a preset temperature range. Wow; Subsequently, it is determined whether the return temperature of all rooms having the valve "on" condition is above a predetermined heating minimum temperature, and if the temperature is higher than that, returning to the initial stage, and if less, indicating that the heating capacity is insufficient on the display unit of the central room cone; It is characterized by further performing.

If the minimum value (Tmin) is higher, the tapping setting temperature (Tset) of the heat source or boiler is lowered by one step to a preset temperature range. Returning to the step; characterized in that the further implementation.

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

Figure 1 shows a schematic block diagram of the entire room heating system to which the present invention is applied, Figure 2 shows a flowchart for explaining the method of the present invention, Figure 3 is the heating temperature of each room by the method of the present invention. The graph shows the state that is automatically adjusted.

First, each room heating system to which the method of the present invention is applied includes a room controller 2 including a heat source or a boiler 1 including a district heating system, a storage device such as first and second timers and an EEPROM, and the like. Equipped with an indoor temperature detection sensor 31, and equipped with several room cones (3) and automatic heating temperature control keys (81) installed in each room, and installed in the living room to monitor the use of hot water, including the heating state of each room At the same time, it detects the central room cone 8 which controls the heating of the room where the room cone is installed, the several valves 4 which control the number of heating in each room, and the heating return temperature passing through the valves 4 of each room. A plurality of heating return temperature detection sensor 6, the tapping temperature detection sensor 7 for detecting the tapping temperature of the heat source or the boiler 1 and the control of the controller 2 to control the opening and closing of the valves (4) With several valve drivers 5 And there.

Each room heating system having such a configuration normally controls the controller 2 when a heating " on " signal is input to any one of the room cones 3 in each room, including the central room cone 8, before implementing the method of the present invention. Recognizes this and opens the valves in the room 100% to maintain the first time t1 determined by the first first timer (not shown), and then the heating return temperature detection sensors 6 installed in each room are The return temperature of each room is detected and stored in a specific location of a storage device such as EEPROM, and then the return temperature of each room corresponding to the valve which is 100% open every second time (t2) determined by the second timer is measured. If the difference from the measured value is within the saturation judging temperature range (± X ℃), the valve opening amount of the room with the lowest return temperature is maintained at 100%. Water temperature is also given to lower in proportion to the ratio corresponding to the difference with a function of controlling the amount of heat supplied to each room to be automatically changed.

In this way, the controller 2 is installed in the central room cone 8 while the operation of lowering the valve opening amount of the rooms in which the heating " on " signal is inputted is proportionally lowered at a rate corresponding to the difference in return temperature for each room. It is determined in real time whether the automatic heating temperature control key 81 is "on" by the user (S1).

As a result, when it is detected by the user that the heating temperature automatic adjustment key 81 installed in the central room cone 8 is "on", the return temperature for each room in the state where the valve is open at that time is detected and shown, respectively. Although omitted, it is stored in a specific place in a storage device, such as an EEPROM installed in the controller 2, that is, a predetermined place (A) (S2).

Subsequently, although not shown, after operating the second timer provided in the controller 2, the count is continued until the second time t2 defined by the second timer elapses (S3).

In this case, the first time t1 was set to 3-7 minutes obtained by the experiment at a time sufficient for each initial return temperature of each room having a heating “on” state to reach a saturation temperature, and the second time (t2) was set to 1-3 minutes obtained by the test with a time sufficient for all the return temperature difference of each room which has a heating "on" state to reach predetermined saturation temperature (+/- degreeC).

On the other hand, as a result of counting the second time t2 as described above, when the second time has elapsed, each return water temperature in which the valve is open is detected and stored in the predetermined place B of the storage device such as EEPROM (S4). ), And after the second time has elapsed compared to the return temperature of each room that is detected and stored in the predetermined place (A) before the start of counting of the second time, it is again detected and stored in the predetermined place (B). Calculate the difference (C) for each room and then determine whether the difference in return temperature of all rooms is within the determined saturation judgment temperature range (± X ℃) (S5). X ° C) is not narrowed down to detect the return temperature for each room in the state where the valve is currently open and return to the step (S2) of storing in a predetermined place (A), and repeats thereafter. .

That is, the difference between the return temperature of each room stored at the designated place (A) and the return temperature of each room (C) stored at the designated place (B) does not fall within the specified saturation judgment temperature range (± X ° C). Even if the saturation judgment temperature range (± X ℃) is higher than the specified saturation judgment temperature range (± X ℃), the specified temperature is detected by detecting the return temperature for each room in which the valve is currently open until the difference in return temperature of all rooms is narrowed within the saturation judgment temperature range (± X ℃). From the step S2 of storing in (A), the following steps are repeated.

However, as a result of the above determination, if the return temperature difference of all rooms is narrowed within the predetermined saturation judgment temperature range (± X ℃), the average value of the return temperature of the rooms where the valve is currently open is calculated and stored in the designated place (C) of the EEPROM. (S6).

At this time, the predetermined saturation judgment temperature range (± X ℃) is the storage place after the second time (t2) has elapsed at the return temperature of each room stored in the storage place (A) before counting the second time (t2) The absolute value for the return temperature difference (C) of each room stored in (B) was obtained by the test so as to have a value of ± 1 ° C to ± 3 ° C.

In addition, when the average return temperature of each room is calculated in the above, it is determined whether the value is the first limit temperature (Y1 ° C.), for example, 34-36 ° C. or more, which is determined to be higher in the heating temperature automatic control function (S7). If the average return temperature of each room is equal to or greater than the first limit temperature (Y1 ° C.), it is determined whether the tapping temperature Tout of the heat source or the boiler detected by the tapping temperature detection sensor 7 is the minimum value Tmin or higher. (S8).

As a result of the determination, when the current tapping temperature Tout of the heat source or the boiler is at the minimum value Tmin (for example, 39-41 ° C.), the tapping set temperature Tset of the heat source or the boiler is maintained at the current state (S9) and the minimum value is set. If Tmin or more, the tapping temperature Tset of the heat source or the boiler is lowered by one step (S10), and then returned to the initial step (S1).

At this time, the reference temperature when lowering or raising the tapping set temperature (Tset) of the heat source or the boiler can be set differently according to the heat amount of the heat source or the boiler. It was set at 2 ° C.

On the other hand, if it is determined in the step (S7) that the average return temperature of each room is less than the first limit temperature (Y1 ℃), this time the average return temperature of each room is a predetermined second limit temperature (Y2 ℃), for example 29- It is determined whether the temperature is less than 31 ° C. (S11), and as a result, when the average return temperature of each room is higher than the second limit temperature Y2 ° C., the tapping set temperature Tset of the heat source or the boiler 1 is maintained in the current state.

However, as a result of the above judgment, if the average return temperature of each room is less than 29-31 ° C, which is the second limit temperature (Y2 ° C), the tapping temperature Tout of the heat source or boiler is the maximum value Tmax (for example, 80-85 ° C). It is determined whether or not or not (S12).

As a result of the above determination, if the maximum value Tmax is 80-85 ° C., the tapping set temperature Tset of the heat source or the boiler is maintained at the present state (S13), and if it is below the maximum value Tmax, the tapping set temperature Tset of the heat source or the boiler is determined. To raise the first stage (for example 1-2 ℃) (S14).

Thus, the tapping temperature (Tout) of the heat source or the boiler is the maximum value (Tmax) so that the tapping setting temperature (Tset) is maintained at the current state or the tapping setting temperature (Tset) of the heat source or boiler is set to 1 or less than the maximum value (Tmax). After the step is increased (for example, 1-2 ° C.), the controller 2 determines whether the return temperature of all rooms having the valve “on” condition is higher than or equal to a predetermined heating minimum temperature (S15). Returning to S1) and starting again from the beginning, if it is less than that, the display unit 82 of the central room cone 8 lacks the current heat source or the heat of the boiler 1 so that the heating capacity cannot be heated for each room. It will indicate the status so that the user can recognize it and take the necessary action as soon as possible.

On the other hand, when it is determined in real time whether the heating temperature automatic control key 81 installed in the central room cone 8 is "on" in the controller 2 at the beginning of the operation of the present invention, the heating temperature is automatically adjusted. As in the case where the key 81 is "on", at that point, the return temperature for each of the chambers in which the valve is currently opened is detected and not shown, but specific in the storage device such as an EEPROM installed in the controller 2 is omitted. That is, the place is stored in the predetermined place A (S17).

Subsequently, although not shown, after operating the second timer provided in the controller 2, the coefficient S18 is continued until the second time t2 defined by the second timer elapses, and then, by the second timer. When the set second time (i.e., 1-3 minutes) elapses, each return water temperature in which the valve is open is detected and stored in a predetermined place B of a storage device such as EEPROM (S19).

Subsequently, the difference between the return temperatures of each room detected and stored at the designated place B after the second time has elapsed compared to the return temperature of each room detected and stored at the designated place A before the counting start of the second time. Calculate each room by room and then determine whether the return temperature difference of all rooms is within the determined saturation judgment temperature range (± X ℃; ie ± 1 ℃ to ± 3 ℃) (S20). Since it is not narrowed within the judgment temperature range (± X ° C), the flow returns to the step S17 of detecting the return temperature for each room in the state where the valve is currently open and storing it in the predetermined place (A). do.

That is, the difference between the return temperature of each room stored at the designated place (A) and the return temperature of each room (C) stored at the designated place (B) does not fall within the specified saturation judgment temperature range (± X ° C). Even if the saturation judgment temperature range (± X ℃) is higher than the specified saturation judgment temperature range (± X ℃), the specified temperature is detected by detecting the return temperature for each room in which the valve is currently open until the difference in return temperature of all rooms is narrowed within the saturation judgment temperature range (± X ℃). From the step S17 of storing in (A), the following steps are repeated.

However, as a result of the above judgment, if the return temperature difference of all rooms is narrowed within ± 1 ℃ to ± 3 ℃, which is the determined saturation judgment temperature range (± X ℃), the average value of the return temperature of the rooms where the valve is open is calculated and the EEPROM is determined. It is stored in the place (C) (S21).

In addition, when the average return temperature of each room is calculated in the above, it is determined whether or not the value is the third limit temperature (Y3 ° C.), for example, 44-46 ° C. or more, which is determined to be higher in the heating temperature automatic control function (S22). If the average return temperature of each room is equal to or greater than the third limit temperature (Y3 ° C.), it is determined whether the tapping temperature Tout of the heat source or the boiler detected by the tapping temperature detection sensor 7 is the maximum value Tmax or higher. (S23).

As a result of the determination, when the current tapping temperature Tout of the heat source or the boiler is at the maximum value Tmax (for example, 80-85 ° C.), the tapping set temperature Tset of the heat source or the boiler is maintained at the current state (S24). If Tmax or more, the tapping temperature Tset of the heat source or the boiler is increased by one step (for example, 1-2 ° C.) (S25), and then returned to the initial step (S1).

On the other hand, if it is determined in the step (S22) that the average return temperature of each room is less than the third limit temperature (Y3 ℃), this time the average return temperature of each room is a predetermined fourth limit temperature (Y2 ℃), for example 39- It is determined whether or not less than 41 ℃ (S26) and as a result, if the average return temperature of each room is higher than the fourth limit temperature (Y4 ℃) it maintains the tapping set temperature (Tset) of the heat source or boiler (1) in the current state.

However, as a result of the above determination, if the average return temperature of each room is less than 39-41 ° C. which is the fourth limit temperature (Y 4 ° C.), the tapping temperature T out of the heat source or the boiler is the minimum value T min (eg 38-40 ° C.). It is determined whether or not or not (S27).

As a result of the above determination, if the minimum value Tmin is 38-40 ° C., the tapping set temperature Tset of the heat source or the boiler is maintained at the present state (S28), and if the minimum value Tmin is lower than the tapping set temperature Tset of the heat source or the boiler. To raise the first stage (for example 1-2 ℃) (S29).

In this way, the tapping temperature (Tout) of the heat source or the boiler is the minimum value (Tmin) to maintain the tapping set temperature (Tset) in the present state, or is below the minimum value (Tmin) so that the tapping set temperature (Tset) of the heat source or the boiler is 1. After the step is increased (for example, 1-2 ° C.), the controller 2 determines whether the return temperature of all rooms having the valve “on” condition is higher than or equal to a predetermined heating minimum temperature (S15). Returning to S1) and starting again from the beginning, if it is less than that, the display unit 82 of the central room cone 8 lacks the current heat source or the heat of the boiler 1 so that the heating capacity cannot be heated for each room. It will indicate the status so that the user can recognize it and take the necessary action as soon as possible.

As described above, in the present invention, the user does not select or set the heating temperature automatic adjustment function, which is the saving mode, through the automatic heating temperature adjustment key installed in the central room cone 8, regardless of the season of 365 days a year. By maintaining the temperature (that is, 29 ~ 36 ℃ when the automatic heating temperature control function is selected, and 39 ~ 46 ℃ when the automatic heating temperature control function is not selected), the user can always be provided with a comfortable environment. By automatically adjusting the tapping water temperature of the tapping water temperature according to the average return temperature and the current tapping temperature, the energy saving can be greatly saved and the reliability of using the product can be greatly improved.
