Description

{COMPOUND INDIVIDUAL FLOW CONTROL SYSTEM}

The present invention relates to a system for individually controlling the heating of each room in a building, and more particularly, to an individual flow control system capable of providing flexible and efficient heating operation by providing individually adjustable valves for each room.

Generally, since most of the district heating type apartments lock a part of the heating valve, so much hot water flows to the next room where the valve is opened, and since the total amount of hot water coming into one household is designed to be unchanged, I only open one, but the same amount of hot water comes in.

In other words, as a result of using the constant flow valve, irrespective of locking the valve in any way, the same amount of flow that is originally set is generated.

Furthermore, even if only one valve is opened, the room is not warmed up so quickly and the hot water is not immediately shut off at the specified temperature.

This type of district heating, which has been adopted by most apartments built in the early 1980s and early 1990s, has the same problems as above. Residents of apartment buildings often shut down heating valves to save heating costs, Because of the fundamental problem of the valve device, heating cost was not reduced, and it was often cold winter.

Accordingly, there is a constant demand for an economical and efficient heating apparatus and a heating control system which can individually and individually heat in consideration of the usage situation of a building or a private house.

The present invention relates to a heating energy management system for controlling heating equipment for heating the inside of a building, as shown in FIGS. 2 to 5, 400 and a flow control unit 500. [

The supply pipe 100 can supply the heating fluid to each generation.

The inlet pipe 200 communicates with the supply pipe 100 and is branched by each of the chambers 30 to communicate the heating fluid so that latent heat of the heating fluid can be exchanged with the corresponding chamber 30. [

The circulation pipe 300 communicates with the inlet pipe 200 and passes through the chambers 30, so that the heating fluid having undergone the heat exchange can be recovered.

The discharge pipe (400) communicates with one of the water return ducts (300) to collect the heated fluid collected through the water return ducts (300) and discharge it to the outside of the household.

The individual flow rate control valve 520 refers to the "combined individual flow rate control system" and is installed in the inlet pipe 200 and controls the flow rate of the heating fluid supplied through the inlet pipe 200 to the use The heating time can be adjusted by individually controlling according to the state.

The flow control unit 500 may include a temperature sensor 510, an individual flow control valve 520, an ON-OFF driver 522, and a controller 530.

The temperature sensor 510 may be installed in the water return line 300 to measure the water temperature of the water return line 300.

The individual flow control valve 520 is installed in each of the inlet pipes 200 and can control an inflow amount of the heating fluid flowing into each of the chambers 30 through the inlet pipe 200.

The ON-OFF driver 522 functions to turn ON / OFF the operation of the individual flow control valve 520 so that the individual flow control valve 520 can be operated.

The controller 530 controls the operation of the individual flow control valve 520 based on the data measured by the temperature sensor 510. When the flow rate is concentrated or changed into one of the individual flow control valves 520, 30) can be adjusted to be even.

As an example of the individual flow control valve 520 used in the flow control unit 500, the range of the inflow flow rate may be differentiated according to the numerical value of the inflow flow rate that is set so that the flow rate introduced into each chamber 30 can be individually controlled Lt; RTI ID = 0.0 > 521 < / RTI >

The proportional actuator 521 controls the flow rate of the fluid in accordance with the conditions of the respective chambers 30 by adjusting the dial gauge of the flow control unit 500 to a predetermined scale and adjusting the flowable total flow rate according to the set scale.

For example, a scale of 1 to 10 is displayed on the dial gauge of the proportional actuator 521, and basically, the maximum allowable flow rate (total flow rate) may be set to 4 when the scale is 3.

However, when the scale is changed to 1, the total flow is changed to 2.5 and the scale is changed to 3 or less. When the scale is changed to 6 or 10, the total flow is changed to 5 or 6, Thereby enabling fine flow control.

Thus, efficient and flexible inflow flow control becomes possible, so that efficient and effective individual heating control for each of the chambers 30 becomes possible.

Scaling of the dial gauge of the proportional actuator 521 can be automatically controlled by an internally inserted motor or manually controlled.

The controller 530 detects the opening and closing states of the individual flow control valves 520 and controls the individual flow control valves 520 to open the chambers 30 The heating time of the chamber 30 can be shortened by concentrating the inflow amount of the heating fluid into the inflow conduit 200 connected to the inflow pipe 200.

That is, the flow control unit 500 provides differential heating according to the control of the outside, and the rooms 30 are used or closed while concentrating or limiting the inflow amount of the heating fluid for each of the rooms 30, Can be shortened.

More specifically, the controller 530 may control the inflow pipe 200 to supply the heating fluid at a predetermined ratio to each of the rooms 30, The heating fluid is prevented from flowing into the closed chamber 30 so that the heating is interrupted and the inflow of the heating fluid is concentrated only in the chamber 30 which is currently in use and the chamber 30, It is possible to improve the energy efficiency by controlling the inflow amount of the heating fluid and shortening the heating time.

The controller 530 controls the individual flow control valve 520 to control the flow rate of the heating fluid flowing into the respective chambers 30 when the temperature of each of the chambers 30 measured by the temperature sensor 510 is non- The temperature of each of the chambers 30 can be uniformly maintained.

That is, the flow rate control unit 500 is connected with a wired or wireless connection so that monitoring can be performed between each other, and the flow rate control unit 500 concentrates or restricts the amount of the heating fluid inflow according to the use state or the temperature difference of each chamber 30, Can be autonomously adjusted.

Specifically, when the temperature measured by the temperature sensor 510 provided in each of the chambers 30 varies from room 30 to room 30, if the heating is disturbed effectively, the temperature of each room 30 is maintained uniform The controller 530 connected to the wireless or wired line controls the flow control unit 500 to control the inflow amount of the heating fluid for each chamber 30. The chamber 30 having a temperature higher than the set temperature reduces the inflow amount and controls the temperature The amount of inflow is increased in the chamber 30, which is lower than the set temperature, so that the temperature of each chamber 30 can be uniformly maintained to induce efficient heating.

First, for example, four chambers 30 of R-1: R-2: R-3: R-4 are arranged in a ratio of 4: 3: 2: 1 Set the heating fluid to flow.

The total inflow amount due to ON / OFF of each of the chambers 30 is shown in Table 1 below.

INDEX R-1 R-2 R-3 R-4 Total Supply Flow 0001 X X X X 0 0002 O X X X One 0003 X O X X 2 0004 X X O X 3 0005 X X X O 4 0006 O O X X 3 0007 O X O X 4 0008 O X X O 5 0009 X O O X 5 0010 X O X O 6 0011 X X O O 7 0012 O O O X 6 0013 O O X O 7 0014] O X O O 8 0015 X O O O 9 0016] O O O O 10

When it is necessary to heat only the desired chamber 30 at a rapid rate, that is, when the valves of the chambers 30 of R-2, R-3 and R-4 are closed, the controller 530 detects this The heating time can be shortened by supplying the heating fluid only to the "R-1" chamber 30 and adjusting the heating flow rate of the "R-1" chamber 30 to 6.

The heating fluid is introduced into the R-1, R-2, R-3 and R-4 chambers 30 at a ratio of 4: 3: 2: 1, If the temperature rises unevenly at 22 占 폚: 23 占 폚: 21 占 폚: 24 占 폚, the efficiency of heating may decrease.

In this case, when the temperature of each of the chambers 30 is varied by a predetermined temperature or more after the control of the controller 530, for example, the maximum temperature of the room temperature displayed on the display panel 550 When the difference between the temperature and the minimum temperature is more than 1 ° C or the temperature sensor 510 installed in the water return line 300 determines that the water temperature of the water return line 300 is different from the maximum temperature and the minimum temperature by more than ± 3 ° C The rate of the heating fluid inflow capacity of the "R-3" chamber 30 is increased to 3, the inflow capacity of the "R-3" chamber 30 is increased to 0.5, "R And the inflow capacity of the " -2 "chamber 30 is adjusted to 2.5, respectively, so that the temperatures of the respective chambers 30 can be uniformly maintained.

Accidental flow control for each such private room has been described above with the proportional actuator 521 above.

The above numeric values are only examples of the control system of the present invention, and are not limited to the above-described numerical values, and can be applied under various conditions while varying numerical values.

In the table, "O" means that the individual flow control valve 520 of the corresponding heating space is open and "X" means that the individual flow control valve 520 of the corresponding heating space is closed.

The flow rate control unit 500 may further include a pressure sensor 540 and a display panel 550.

The pressure sensor 540 may measure the pressure of the heating fluid supplied to the inlet pipe 200 through the supply pipe 100 and provide the measured pressure to the controller 530.

That is, the operator can use the pressure sensor 540 to monitor the flow rate of the heating fluid communicating through the inflow conduit 200 and take over the controller to prevent the overpressure in the inflow conduit 200 from being generated.

The display panel 550 may be connected to the controller 530 to display the measurement values of the pressure sensor 540 and the temperature sensor 510 or the operation state of the individual flow control valve 520.

In addition, the control system 10 of the present invention may further include a wireless communication module 600 so that the operation of the flow control unit 500 can be externally and wirelessly controlled.

Accordingly, since the operator can operate the control system 10 from the outside through the wireless communication module 600, the operator can preliminarily supply heating to the building or the rooms to be used to maintain a comfortable environment.

The controller 530 of the present invention may be a part of the flow control unit 500 or may be connected to the flow control unit 500 while being installed outside the flow control unit 500.

The control system 10 of the present invention may further include a main temperature sensor 711 in the shut-off valve 700.

The shutoff valve 700 is installed in the supply pipe 100 and the discharge pipe 400 and is connected to the supply pipe 100 and the discharge pipe 400 through the opening and closing of the individual flow control valve 520, The inflow and outflow amount of the communicating heating fluid can be controlled to maintain the temperature difference in the set range.

Specifically, the temperature is measured for each section through the main temperature sensor 711 of the shut-off valve 700 and the temperature range is set.

For example, when the supply pipe 100 is set at 60 ° C and the discharge pipe 400 is set at 45 ° C, and when the difference is more than ± 3 ° C at the set temperature for each section, that is, 60 ° C - 45 ° C = (I.e., DELTA t is 15 DEG C), and when a temperature difference of +/- 3 DEG C is generated as compared with DELTA t, i.e., a temperature difference larger than DELTA t = 18 DEG C appears, the individual flow control valve 520 is controlled to a certain degree If the temperature difference is smaller than? T = 12 占 폚, the individual flow regulating valve 520 is closed to a certain degree or more so that the discharge amount of the heating fluid is controlled, The temperature difference of each section of the discharge pipe 400 can be maintained within the set range.

The main temperature sensor 711 is separately provided in the state of being contained in the shut-off valve 700 to measure the temperature of the inlet pipe 200 and the water return pipe 300, or separately from the shut- And the temperature of the water return line 300 can be measured.

The main flow meter 710 and the main pressure gauge 720 may be installed in the supply pipe 100 and the discharge pipe 400, respectively.

The main flow meter 710 is installed in the supply pipe 100 and the discharge pipe 400 and controls the inflow and outflow amount of the heating fluid communicated to the supply pipe 100 and the discharge pipe 400 The actual flow value can be measured to maintain the temperature difference in the set range.

The main flow meter 710 continuously monitors the flow rate flowing through each of the supply pipe 100 and the discharge pipe 400 and transmits the result to the flow rate control unit 500.

In addition, the control of the individual flow rate control valve 520 can be controlled not only individually but also through a central main controller 800 or the like.

The main pressure gauge 720 continuously monitors the water pressure flowing in the supply pipe 100 and the discharge pipe 400, respectively.

If the measured pressure difference? P is smaller than a predetermined range, for example, 0.3 to 0.5 kg / cm 2, the individual flow control valve 520 is closed to a certain extent to increase the pressure difference, Range, the individual flow control valve 520 is opened to a certain degree and the pressure difference is controlled to be small so that efficient heating control is possible.

In addition, the present invention may further include a main controller 800 and a sub-controller 810.

The main controller 800 may be connected to the flow control unit 500 to control the operation of the flow control unit 500 from a centralized point of view.

The subcontroller 810 is connected to the main controller 800 and the flow control unit 500 and is installed separately for each chamber 30 to control the operation of the flow control unit 500 in conjunction with the existing products. (30).

That is, the flow control unit 500 of each of the chambers 30 can be controlled collectively through the main controller 800 installed at the central portion of the living room of the house to maintain proper heating, and the main controller 800 The sub-controllers 810 are installed separately for each of the rooms 30 so that efficient heating can be performed through individual heating control for each room 30. [

When the individual flow control valve 520 connected to the chamber 30, which requires heating by the individual flow control system of the present invention or needs to be heated locally rapidly, is opened, the controller 530 detects the flow control valve 520, The heating fluid can be intensively introduced into the chamber 30 through the heat exchanger 200 to shorten the heating time, thereby improving the heating efficiency.

In addition, when the chambers 30 are set to maintain a uniform temperature through the controller 530, the controllers 530 are interlocked with each other in a wired or wireless manner to maintain the uniform temperature of the chambers 30 The operation of the flow rate control valve 520 is controlled to concentrate or limit the inflow amount of the heating fluid to each of the chambers 30, thereby efficiently heating the entire building.

In addition, since the conventional central control heating system requires a separate management device or facility such as a central management room, the initial installation cost and the maintenance cost of the system are increased, while the individual flow control system of the present invention is configured such that the flow control unit 500 It is economical compared with the conventional central control type constant flow valve (1) because the installation is relatively simple and the initial installation cost is low and the separate maintenance system is not required.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And such variations and modifications are intended to fall within the scope of the appended claims.
