Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating control apparatus and a heating control apparatus,

The present invention relates to an apparatus and method for controlling the heating temperature of a cubic control system using a boiler return water temperature, and more particularly, to a system and method for controlling a cubic control system using an on / off valve driver, The present invention relates to a control system using a boiler return temperature, which can control a heating temperature of each room by calculating a size (a pipe length) of a room to be heated so as to solve a heating unbalance problem in which a floor temperature varies according to a pipe length To a heating temperature control apparatus and a method thereof.

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.

2. Description of the Related Art [0002] In recent years, a cubic control system has been developed and widely used for heating and supplying hot water to a plurality of rooms using a single boiler. Such a system has a main remote controller, ) And a multi-remote controller (hereinafter abbreviated as "room controller") composed of at least one wired or wireless sub-remote controller.

At this time, the central room controller is configured to be able to set various functions such as heating and heating temperature, and to display the results thereof, and the room controllers, which are sub-remote controllers installed in other kitchens or other rooms, Operation and setting, and the result thereof can be displayed.

Accordingly, the user can control whether or not the entire room is heated, the heating temperature, and the like through the central room controller. Further, the user can control the heating and the heating temperature of the corresponding room through each room controller, There is also a function of exchanging various information through the bidirectional communication between the controller and the boiler to check the state of the boiler through the central room controller and the room controller.

As a conventional individual heating control device (or system) having one central room cone and a plurality of room cones and performing the opening and closing operations of the respective valves and the driving control of the boiler, as disclosed in Korean Patent Publication No. 10-0196744 And 10-0438313. ≪ Desc / Clms Page number 2 >

On the other hand, in a building using a boiler and other heat sources interlocked with a cubic control system, when a heating valve installed for each room or each zone is on / off controlled, the length of the heating pipe is usually different, There are many households where heating imbalance occurs despite the closing.

Therefore, in recent years, in order to prepare for such a case, there is a manual flow rate control divider that installers manually set the opening degree of the heating valve in the installation of the distributor according to the length of the piping. However, When the heating is turned "on", the entire heating flow rate is not sufficient, so boiling or boiling of the heat source often occurs. Thus, bypass piping must be separately installed.

In addition, there are automatic flow distributors and electric heating valves that detect the return water temperature or flow rate of each room and adjust the opening of the heating valve in real time. However, since most of the heating valves are equipped with DC motors, The control method is complicated and the price of the product is quite high.

In order to solve the above-mentioned conventional problems, a "micro flow rate control and noise prevention system for a hot water distributor using a motorized valve" has been developed and disclosed in Korean Patent No. 10-0865948.

However, in the micro flow rate control and noise prevention system of the hot water distributor using the electric valve, two micro switches for controlling the power supplied to the AC synchromesh motor in the electric valve driver, that is, And the two microswitches for turning on / off the microswitch for closing and the microswitch for closing are provided, so that the volume of the electric valve actuator itself is very large, and the production cost of the product is increased There is a problem that the number of components is large and the failure rate is high.

Korean Registered Patent No. 10-1039911 (June 01, 2011) Korean Registered Patent No. 10-1506987 (Mar. 24, 2015) Korean Registered Patent No. 10-1476645 (December 19, 2014)

In the method of the present invention,

In constituting the heating temperature control method of the cubic control system,

A step S2 of checking whether the rooms 2 to be heated are two or more when the micom 2 of the controller 2 checks the output states of the respective room cones 4 when the heating temperature leveling for specific rooms is started in the boiler 1 )Wow;

If the number of rooms to be heated is two or more (Yes in S1), all of the valve actuators 5 of the rooms to be heated are operated to turn on all the heating valves 3 installed on the heating pipes 7 of the corresponding rooms (S2) of starting heating;

A step (S3) of starting a coefficient for the determined first heating time (X);

Determining whether the first heating time (X) has elapsed (S4);

When the first heating time (X) elapses after the start of heating, the heating valve (3) is opened for a second time (Y) sequentially sequenced in any one of all the heating rooms and the circulation pump (S5) detecting and storing the return water temperature for the rooms when the second time (Y) elapses, through the return water temperature detection sensor (6) installed on the water inlet side of the boiler (1);

If the result of the maximum return temperature (Max) -minimum return temperature (Min) is lower than or equal to the predetermined first temperature (A) (No at S6), the heating is recognized as being averaged within the predetermined temperature range And terminating the heating temperature leveling (S10).

At this time, the first heating time (X) is an initial stabilization time necessary for stabilizing the heating temperature of each room by sufficiently supplying the heating water to the heating pipes (7) of each room where the heating is performed, And the amount of heat of the boiler 1, but in the present invention, it is set to 8 to 12 minutes,

The second time (Y) is the time for which the heating water has already flowed during the first heating time (X), and the initial heating water in each heating pipe is circulated and the heating temperature is stabilized. In order to estimate the difference of the heating load, it is time to detect the temperature of the return water one by one. In the present invention, it is set to 2 to 4 minutes,

The first temperature (A) is set to 8 to 12 ° C in consideration of the fact that the heating temperature is different according to the length of each heating pipe (7) for the same period of time.

As a result of judging whether or not the result value of the maximum return water temperature (Max) -minimum return water temperature (Min) among the respective water heat exchanger temperatures stored in the microcomputer 2 of the controller 2 is larger than the first temperature (A) If the result of the maximum return temperature (Max) - the minimum return temperature (Min) among the return temperature of the exhaust gas temperature is greater than the first temperature (A) determined (Yes in S6)

A step (S7) of judging whether or not there is a room representing a water-return temperature within a second temperature (B) which is determined from a maximum water-return temperature (Max)

If there is a room representing the water-return temperature within the second temperature B determined from the maximum water-return temperature Max of the room showing the maximum value (Yes in S7), the room indicating the maximum water-return temperature Max The heating valve 3 of the other heating room is turned off to the heating valve 3 of the room showing the refill temperature within the second temperature B defined by the reflux temperature and the third heating time Z (S8), all the valve actuators 5 of the rooms to be heated are operated to turn on all the heating valves 3 installed on the heating pipe 7 of the corresponding room and start heating The process returns to step S2 to repeat the steps thereafter.

In step S7, the microcomputer 2 of the controller 2 determines whether there is a room representing a temperature of the water within the second temperature B, which is set to be higher than the maximum water-return temperature Max of the room, result,

(No in S7), only the heating valve 3 of the room showing the maximum return water temperature Max is set to "Off " The heating valves 3 of the other heating rooms are all turned "on", the heating is further carried out for the third heating time Z (S9), and then all the valve actuators 5 in the rooms to be heated And the heating valves 3 installed on the heating pipe 7 of the corresponding room are all turned "on ", and the process returns to the step S2 of starting heating, and the subsequent steps are repeated.

Here, the second temperature (B) is a temperature difference which is a reference for finding a room having a temperature difference relatively less than a water return temperature of a room showing a maximum value in order to find a room that is not a heating imbalance, The third heating time Z is a heating time that can be taken to quickly equalize the return temperature of the rooms less than or equal to the second temperature B determined from the maximum return temperature, But it is set to 3 to 5 minutes in the present invention.

When the microcomputer 2 of the controller 2 checks the output status of the room controllers 4 and judges whether there are two or more rooms being heated,

Heating only the valve driver 5 and the heating valve 3 of the corresponding room (step S11), and returning to the initial step S1.

The operation and effect of the heating temperature control apparatus and method of the cubic control system using the boiler return temperature according to the present invention having the above-described configuration and steps will be described as follows.

First, as shown in FIG. 1, the present invention apparatus is provided with a return water temperature detection sensor 6 on the side of a boiler 1 water inlet of a known cubic control system, so that each heating control valve 3 (Not shown) of the boiler (not shown) when the averaged return temperature of the heating water circulating in the heating pipes 7 of the rooms in which the heating pipes are opened and the heating valve of the specific room are opened, 1) internal control unit to the controller 2 as a main technical constituent element.

The known cubic control system includes a boiler 1 including a circulation pump 11, a heat exchanger, a burner, etc., a plurality of heating valves 3, 4, a controller 2, and a plurality of valve actuators 5.

A plurality of heating valves 3 are provided on each of the heating pipes 7 and are turned on and off by a valve driving part 23 operated by the output signal of the controller 2 to control heating pipes And the plurality of room cones (4) are connected to the controller (2) in a state where the plurality of room cones (4) are installed in the respective rooms, wherein the temperature and the driving time of the hot water and the heating water, So that the opening degree of the heating valve can be set.

The controller 2 is provided with a communication signal processing unit 21, a microcomputer 22 and a valve driving unit 23 and is installed between the boiler 1, the valve driver 5 and the room cone 4 Off control for each heating valve 3 through the valve actuators 5 including the driving control of the boiler in response to the control signals transmitted from the boiler 1 and the room con- dens 4 through the bidirectional communication line, Function.

The plurality of valve drivers 5 are respectively provided in the heating valves 3 and directly control ON / OFF control of the respective heating valves 3 corresponding to output signals of the controller 2 .

2, when the heating temperature leveling for specific rooms is started in the boiler 1, the microcomputer 2 of the controller 2 confirms the output status of each of the room cones 4 (S1). If it is determined that two or more rooms are desired to be heated (No in S1), only the valve driver 5 and the heating valve 3 of the corresponding room are turned on via the valve driving unit 23, The operation is performed (S11), the room is heated, and the process returns to the initial stage (S1).

However, if there are two or more rooms to be heated (Yes in S1), all of the valve actuators 5 of the rooms to be heated are operated to turn on all the heating valves 3 installed on the heating pipes 7 of the rooms, In this state, heating of each room is started (S2).

Subsequently, although not shown, a count for the first heating time X determined by the counter provided in the microcomputer 2 is started (S3), and it is determined whether the first heating time X has elapsed (S4) .

At this time, the first heating time (X) is an initial stabilization time necessary for sufficiently heating the heating water of each room to sufficiently heat the heating water in each of the heating pipes (7) 7) length and the amount of heat of the boiler 1, which is set to 8 to 12 minutes in the present invention.

If it is determined that the first heating time X has elapsed in the microcomputer 2 of the controller 2 as a result of the determination in step S4 that the first heating time X has elapsed after the start of heating, The circulation pump 11 is driven so that the heating valve 3 is opened for a second time (Y) sequentially determined one by one and the temperature of the present heating pipe is measured quickly through the temperature sensor 6 for returning water And the water temperature for the respective rooms are detected through the water temperature detection sensor 6 provided on the water inlet side of the boiler 1 at every lapse of the second time Y and stored in the microcomputer 2 (S5).

Here, the second time (Y) is a time period in which the heating water has already flowed during the first heating time (X), the initial heating water in each heating pipe is circulated and the heating temperature is stabilized, In order to estimate the difference of the heating load according to the present invention, it is set to 2 to 4 minutes, which is a relatively small time than the first heating time (X) set to 8 to 12 minutes in the present invention.

 At this time, it is also possible to terminate the combustion for the second time (Y), to drive only the circulation pump (11), to circulate the heating pipes in each room, and to detect the temperature of each room.

Subsequently, the microcomputer 2 of the controller 2 reads all of the circulating water temperatures stored in the storage unit and extracts the maximum return water temperature Max and the minimum water return temperature Min among the hot water of these rooms, It is determined whether the result obtained by subtracting the minimum water temperature Min from the water temperature Max is greater than the first temperature A (S6).

In this case, the first temperature (A) is set to 8 to 12 ° C in the present invention in view of the fact that the heating is performed for the same length of time according to the lengths of the respective heating pipes (7) .

In this way, the microcomputer 2 performs the first heating time (X) heating and then the minimum return temperature from the room temperature representing the maximum return temperature Max among the return temperatures of the rooms that have been sequentially heated for the second time (Y) If the result obtained by subtracting the room water temperature Min representing the temperature Min from the value obtained by the maximum water return temperature Max and the minimum water return temperature Min is equal to or lower than the predetermined first temperature A of 8 to 12 ° C (No in S6), it is determined whether or not the circulation temperatures of the rooms to be heated are averaged within the predetermined circulation temperature range (that is, the circulation temperature within the second temperature B determined by the heating temperature of each room being at least the maximum circulation temperature Max And the heating temperature leveling is terminated (S10).

However, as a result of the microcomputer 2 of the controller 2 judging whether the result value of the maximum return temperature Max-minimum return temperature Min among the respective temperatures of the return water stored in the storage unit is larger than the first temperature A, If the result value of the maximum return temperature (Max) -minimum return temperature (Min) among the stored temperatures of the stored cubic temperatures is greater than the first temperature (A) determined (Yes in S6) It is determined whether or not there is a room representing a water-return temperature within a second temperature (B) that is determined based on the temperature Max (S7).

In this case, the second temperature B is a temperature difference which is a reference for finding a room having a temperature difference relatively smaller than a water return temperature of a room showing a maximum value in order to find a room that is not a heating imbalance. Respectively.

If the microcomputer 2 determines that there is a room representing the temperature of the water within the second temperature B determined from the maximum water-return temperature Max of the rooms showing the maximum value among the water-heating temperatures of the respective rooms (S7) (Yes in S7), a room indicating the maximum return temperature (Max) as well as a room indicating the maximum value are set to be higher than the maximum return temperature of the room indicating the maximum value The heating valve 3 of the other heating room is turned " off "to the heating valve 3 of the room showing the return water temperature within the predetermined second temperature B, (S8), then all of the valve actuators 5 of the rooms to be heated are operated to turn on all the heating valves 3 installed on the heating pipe 7 of the corresponding room and start heating S2) and repeats the subsequent steps .

However, if there is no room showing the water-return temperature within the second temperature B determined from the maximum water-return temperature Max of the room showing the maximum value (No in S7), only the heating valve 3 in the room, (S9) for the third heating time (Z) in a state in which all the heating valves (3) of the other heating rooms are turned "on ", and the valve actuators All the heating valves 3 installed on the heating pipe 7 of the corresponding room are turned on and the process returns to the step S2 of starting the heating and the subsequent steps are repeated.

At this time, the third heating time (Z) is set so as to maximize the return temperature of the rooms less than or equal to the second temperature (B), which is lower than the maximum temperature, (Averaged by the circulating water temperature) can be set differently according to the current circulation temperature of the rooms having the second temperature (B) or lower than the maximum return temperature. In the present invention, the heating time is set to 3 to 5 minutes.

Therefore, it is possible to completely solve the problem of unbalance of the heating which is different from the temperature of the floor according to the length of the pipe, so that the reliability according to the control of the boiler itself can be improved greatly.

Although it is not shown in the drawing, after the heating temperature leveling is completed as described above, it is also possible to provide the user with the desired heating temperature according to the heating set temperature set through the room cones 4 installed in each room, Heating temperature control is performed.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Which will be apparent to those skilled in the art.
