A valve with a built-in temperature sensor and an automatic flow control hot water heating system using it}

The present invention relates to a temperature sensor of a flow rate control valve for controlling the flow rate of hot water during heating and a hot water heating system that automatically adjusts the flow rate of hot water using the temperature sensor. It is installed in the flow control valve installed in the return pipe of the hot water and protrudes inside the flow control valve when the hot water supplied to each heating room is recovered. It is formed of a synthetic resin material containing glass fiber to reduce the manufacturing cost, and the flow rate is adjusted using the current temperature and set temperature of each heating room. This is a technical field related to a valve with a built-in temperature sensor that can increase the efficiency of heating by controlling the flow rate and an automatic flow rate control hot water heating system using the same.

In general, heating methods are divided into individual heating methods, central heating methods, and district heating methods depending on the production method of the heat source. Heating is provided to each household by supplying the heat source produced in the central machine room of each complex directly or through a heat exchanger in the machine room, and the district heating method is collectively produced by production facilities such as a cogeneration plant of a certain area or a certain size. It is a method of heating by supplying a heated heat source to an apartment complex or large building in a certain area.

In the heating methods as described above, a distributor for distributing heating water is installed in each heating room requiring heating in common, and the distributor receives heating water through a heating water supply pipe and supplies heating water to each heating room. The heating water supplied to the heating room is configured to be cooled and discharged to the outside through the heating water return pipe after transferring heat energy through the heating pipe installed in each heating room.

At this time, a flow rate control valve corresponding to the number of the heating rooms is installed in the distributor so that the flow rate of heating water is controlled and supplied to each heating room, and the flow rate control valve is the size of each heating room or the external environment. The heating water supply flow rate for heating is differently supplied to each heating room according to the conditions, so that the same temperature rises at a certain time.

According to the control method, these flow control valves are classified into three types: ON/OFF type, constant flow type, and proportional control method. When the temperature of the heating room reaches the temperature set by the user, the valve is blocked to cut off the supply of heating water, and when the temperature of the heating room falls below the temperature set by the user, the valve is closed It is open to supply heating water.

In the constant flow method, when a valve is installed in a heating water return pipe through which heating water is exchanged, heating water does not flow beyond the flow rate set in the valve itself, and heating water is supplied to a plurality of heating rooms from one heating water supply source Since the pipe lengths of each heating room are different, the time for the temperature of each heating room to reach the set temperature is different from each other. Accordingly, by installing a flow rate control valve on a pipe connected to each heating room in order to solve the heating imbalance, the time to reach the set temperature of each heating room is made uniform.

This constant flow method is known to have advantages of reducing the total length of the heating pipe, reducing the number of distributors, and resolving the heating imbalance, and was used in the heating system.

However, in the constant flow method, the construction company sets the flow rate at the time of construction according to the pipe length and the diameter of the pipe, and once the flow rate is set, it is impossible for the user to change the flow rate arbitrarily. If the length is changed, the problem of heating imbalance may occur again.

In addition, in the constant flow method, the amount of heat required in each heating room during heating is not determined only by the length of the pipe, but the location of each heating room (whether it is a sunny room or not), Depending on the conditions, there is a difference in the amount of heat required for each heating room for equalization of the actual heating. There is a problem that this cannot be done.

On the other hand, a proportional control method was developed to solve the problem of the constant flow method as described above. In the proportional control method, a flow control valve is installed in the distributor where the heating water supplied from the heating water supply source passes through each heating room and then is returned. It is installed to adjust the flow rate of heating water to create a comfortable indoor environment according to the temperature set in each heating room.

However, the conventional proportional control type flow control valve controls the supply flow rate of heating water by receiving flow data feedback from the flow sensor and adjusting the opening and closing.

In addition, when the flow sensor is not used, the temperature sensor measures the return temperature of the heating water, and the measured return temperature is fed back to the target (set) temperature and the current temperature until the target temperature is reached. PID (Proportional-plus-Integrate-plus-Derivative) control, which calculates the deviation from and gives a control amount proportional to the deviation value, was used. That is, this method calculates the deviation between the target (set) temperature and the current temperature, adjusts the opening/closing amount of the flow control valve in proportion to the deviation value, and then measures the change in the current return temperature again to measure the opening/closing amount of the flow control valve It is a method to control the flow rate by repeatedly adjusting the opening and closing of the flow control valve until the target (set) temperature is reached.

Since the return temperature of the heating water is the temperature after passing through the heating pipe installed in each heating room, it is the best information to determine the amount of heat required in each heating room, but it is controlled so that the heating of each heating room is uniform. There was a problem in that the response characteristics were too slow to be controlled.

That is, when the flow rate is adjusted by controlling the opening and closing of the proportional control type flow control valve, it takes a lot of time for the adjusted flow rate to affect the heating return temperature, so you can immediately know whether the adjusted flow rate is an appropriate flow rate Since the flow rate control valve is controlled separately for each heating room, a change in the flow rate in one heating room will not only affect the other heating room, but also in each heating room due to the slow response characteristics as described above. It is fatally impossible to control the flow by organically connecting it.

In addition, in the conventional heating system of the proportional control method, when heating only the minimum space among all heating rooms, for example, when heating only one heating room, the circulation of heating water is not smooth, and noise due to the control of the flow rate is generated. However, in the case of a boiler, there is a problem in that the heating is not performed smoothly due to the occurrence of a hunting phenomenon.

In addition, since the conventional heating system of the proportional control method controls only the heating water return temperature, there is a fear that the hot water supply may be blocked regardless of the room temperature, so proper heating control may not be performed. Only by adopting the parallel control method by room temperature (atmospheric) while using the temperature difference in temperature, the heating control in Korea, where hot water heating is the main type, can be smoothly controlled while satisfying the many needs of energy saving and well-being.

As a prior art for satisfying these needs, Korean Patent Laid-Open No. 2007-0032563 discloses a heating control system and heating control method using a difference between a hot water inlet temperature and a return water temperature. That is, after inputting a ΔT value that arbitrarily sets the difference between the inlet temperature and the return temperature difference, the value obtained by subtracting the ΔT value from the inlet temperature is set to an arbitrary set value, and then the return temperature value is set to the set value. When the valve is closed to a certain degree and only a small amount is returned, the above problems are solved and a lot of energy is prevented from being wasted as the burner of the boiler is repeatedly turned ON/OFF.

However, this method compares only the return temperature with the set value by subtracting the inlet temperature and the arbitrarily set temperature difference value. There is a disadvantage in that the heating temperature of each room is unnecessarily prolonged due to the difference in the time when the heating temperature of each room is reached.

More specifically, in the prior art, the temperature difference between the inlet temperature and the return temperature is arbitrarily set, that is, the return reference temperature is determined by subtracting the ΔT value from the inlet temperature, and only the return reference temperature and the return water temperature are compared. By doing so, there is a problem in that heating is not performed smoothly due to excessive or insufficient heating due to a difference in the time required to reach the target temperature, which is the heating temperature, as the current (atmospheric) temperature of each room is not taken into account.

On the other hand, the temperature sensor installed in the proportional control type flow control valve to measure the return temperature protrudes inside the flow control valve, and the protruding outside is generally made of SUS material, and the flow rate control valve is the flow rate of hot water. Since impurities in the hot water are accumulated, there is a problem that the temperature cannot be sensed stably. In this case, it is replaced and installed. However, the temperature sensor including the SUS material has a problem in that the manufacturing cost is high and the maintenance cost is increased.

Republic of Korea Patent Registration No. 10-0952985 (2010.04.07.) Republic of Korea Patent Registration No. 10-1916357 (2018.11.01.)

The present invention is a technology devised to solve the problems according to the prior art. Among the conventional heating methods, the proportional control method using PDI control calculates the deviation between the current temperature and the set temperature and adjusts the flow rate according to the deviation value. After adjusting the opening/closing amount of the valve, by measuring the change in the current return temperature again and adjusting the opening/closing amount of the flow control valve, there is a problem that hot water supply may be blocked or excessive heating may be made regardless of the room temperature of the heating room, In the case of heating only one heating room in a minimum space, for example, there is a problem in that not only noise is generated due to the control of the flow rate, but also a hunting phenomenon occurs, so that heating may not be performed smoothly. Its main purpose is to provide solutions.

In addition, the present invention is a temperature sensor installed to protrude inside the flow rate control valve installed in the hot water return pipe so as to measure the return temperature of the hot water supplied to each household and returned to the hot water return pipe through the hot water supply pipe of the heating room.

The hot water return pipe 400 has one side connected to the hot water supply pipe 300, and the other side is connected to the hot water distributor 200, the hot water supply pipe 300 extending to each heating room (R). It is connected to and passes through each heating room (R) to recover the heat-exchanged hot water so that it can be returned.

The valve 600, that is, the valve 600 having the temperature sensor 620 described above to control the flow rate is installed on the other side of the hot water return pipe 400, and has a actuator 610, and then As the actuator 610 is controlled by the controller 700 to be described in detail, the opening and closing amount is adjusted by the driver 610 to adjust the flow rate of heating water, that is, hot water supplied to each heating room R. characterized in that

The controller 500 is installed in each heating room (R) to determine whether to heat, to measure the current temperature of each heating room (R), and to allow the user to set the set temperature, after The current temperature and the set temperature of the heating room R corresponding to the controller 700 to be described are transmitted so that the flow rate of hot water is controlled by the valve 600 .

The controller 700 is connected to the plurality of controllers 500 to receive information on whether heating is performed or stopped in each heating room (R), and the current temperature and set temperature, and a plurality of valves (600). It is connected to the temperature sensor 620 to control the driver 610 by receiving the exchanged heating water, that is, the hot water exchange temperature every predetermined time. It is characterized in that the flow rate of the hot water supplied to each heating room (R) of the is controlled so that it can be supplied.

At this time, the controller 700 receives the return temperature of the hot water from the temperature sensor 620 of the valve 600 every predetermined time, so that the temperature change of the heat exchanged hot water is periodically grasped and the flow rate of the hot water is adjusted, Accordingly, the heating can be maintained at the reached set temperature. Here, the predetermined time may be, for example, 10 minutes, 20 minutes, 30 minutes, and the like.

More specifically, if the controller 700 receives information on whether or not heating is performed from any one or more of the plurality of controllers 500 as an example, the set temperature of the corresponding heating room R is currently When the temperature is less than the temperature, the amount of closing of the valve 600 of the corresponding heating room R is determined as 100% and the corresponding actuator 610 is controlled, so that hot water is not supplied to the corresponding heating room R. Make sure there is no heating.

In connection with the above, the controller 700 determines the opening amount of the valve 600 of the corresponding heating room (R) when the set temperature of the corresponding heating room (R) exceeds the current temperature, but the setting When the temperature is 2 degrees or more than the current temperature, the opening amount of the valve 600 is determined as 100% so that the current temperature can reach the set temperature in the shortest time.

In addition, when the set temperature of the corresponding heating room R is 1 degree or less than the current temperature, the controller 700 opens the corresponding actuator 610 to open by the opening amount of the preset valve 600 based on the current temperature. ) so that hot water is supplied to the corresponding heating room (R) by controlling the heating to be performed.

At this time, when the set temperature of the corresponding heating room (R) is 1 degree or less than the current temperature, the opening amount of the preset valve 600 is the size of each heating room (R) and the heating environment such as rain wind, heat insulation, etc. It is set in the controller 700 in consideration of the condition.

In addition, the set value of the opening amount of the preset valve 600 when the set temperature of the corresponding heating room (R) is 1 degree or less than the current temperature is the current temperature of the corresponding heating room (R) It is preferable to set as a reference, that is, characterized in that the opening amount is set to be inversely proportional to the current temperature, which is characterized in that the opening of the valve 600 when the current temperature is low (eg, lower than room temperature (25° C.)) By increasing the amount so that the current temperature can quickly reach the set temperature, and when the current temperature is high (for example, when it is higher than room temperature (25° C.)), by reducing the opening amount of the valve 600, the current temperature is low In this case, the temperature should be raised quickly, and if the current temperature is high, the temperature should be raised slowly in consideration of the heating efficiency.

That is, the controller 700 opens and closes the opening amount of the valve 600 to a preset value based on the current temperature when the set temperature of the corresponding heating room R is 1 degree or less than the current temperature, thereby heating efficiency to realize the maximum effect.

In connection with the above, the controller 700 has a set temperature of the corresponding heating room (R) exceeding the current temperature in a state in which it is transmitted whether or not heating is performed from any one or more of the plurality of controllers 500, When the set temperature is less than 2 degrees and 1 degree more than the current temperature, that is, when the set temperature is in the range of 1 < set temperature < 2 compared to the current temperature, the set temperature of the heating room R It is characterized in that it is determined that the current temperature is the same.

That is, when the set temperature of the corresponding heating room (R) is less than 2 degrees and 1 degree more than the current temperature, the controller 700 controls the valve when the difference between the set temperature and the current temperature is in a range where the difference is neither minute nor significantly different. (600) is not opened 100% nor is it opened by the preset flow rate value, and the current temperature reaches the set temperature with the return reference temperature and the additional opening and closing amount of the valve 600 using the return temperature, which will be described in detail later. By doing so, it is characterized in that the current temperature can reach the set temperature more quickly.

In addition, when the controller 500 is initially adjusted for heating, the user sets the set temperature to 2 degrees or more above the current temperature so that the boiler can be operated, so the valve 600 is 100% open during the first heating. The current temperature reaches the set temperature.

At this time, when the current temperature reaches the set temperature or the difference is less than 1 degree, the first valve 600 is more precisely adjusted than the additionally adjusting the opening and closing amount of the valve 600 at 100% of the initial opening and closing amount of the valve 600 . In a state ignoring 100% of the opening/closing amount, that is, assuming that the opening/closing amount of the valve 600 is 0%, the final opening/closing amount of the valve 600 is immediately determined and the current temperature reaches the set temperature, so that the current To maintain the state that the temperature has reached the set temperature, if the current temperature does not reach the set temperature but is less than 2 degrees and exceeds 1 degree, that is, 1 < set temperature < 2, use the return temperature that will be explained in detail later Thus, by determining the additional opening/closing amount of the valve 600, the control of the opening/closing amount from the previously adjusted opening/closing amount of the valve 600 can be made more smoothly.

In addition, since the aforementioned 'one or more of the plurality of regulators 500' means only one regulator 500, the opening amount of the valve 600 can be 100%, so 'at least two regulators 500 )' will be self-evident.

In connection with the above, the controller 700, which has received information on whether or not heating is performed during heating, from any one or more of the plurality of controllers 500, has the valve 600 of the corresponding heating room R currently closed. When the set temperature and the current temperature are the same when the amount or the current opening amount is determined, that is, when the current temperature reaches the set temperature Comparing the return water temperature measured at the valve 600 of (R), if the return water temperature is higher than the return reference temperature, it is determined that the heat exchange is not performed efficiently, and the additional closing amount of the preset valve 600 is determined, Accordingly, by controlling the corresponding actuator 610 to close the valve 600 of the corresponding heating room R by an additional closing amount, it is characterized in that the heating efficiency can be increased.

In addition, the controller 700 determines that the heat exchange is not performed efficiently because the exchange temperature is high, similar to the case where the set temperature of the corresponding heating room R is 1 degree or less than the current temperature. This is determined in consideration of the temperature, which is to reduce the flow rate of hot water when heat exchange is not performed efficiently because the current temperature is high so that hot water can be supplied to the heating room (R) that requires a large amount of hot water. This is to keep the current temperature of (R) reaching the set temperature.

As an example, if heating is being performed in two heating rooms, assuming that the set temperature of one of the heating rooms is 30 degrees and the set temperature of the other heating room is 24 degrees, the current of the two heating rooms is When all the temperatures have reached the set temperature, the current temperature (30 degrees) of any one heating room becomes lower than the current temperature (24 degrees) of the other heating room, and accordingly, the Because the difference between the return water temperature and the return reference temperature recovered from one heating room is greater than the difference between the return water temperature and the return reference temperature recovered from any other heating room that maintains a low current temperature, that is, the amount of heat exchanged is the above. Since there are more other heating rooms, if the return temperature is higher than the return standard temperature in consideration of heating efficiency, the current temperature is considered to determine the additional closing amount.

To explain numerically, when the temperature of the hot water supplied to the heating room is 90 degrees and the standard exchange temperature in consideration of normal heat exchange is 70 degrees, the return temperature of any one of the heating rooms is 80, and the If the return water temperature of the heating room is 75, it is determined that more heat exchange is being performed with the hot water supplied to the other heating room, which has a lower current temperature, and the hot water supplied to the one heating room undergoes heat exchange efficiently. By determining not to lose and determining and controlling the additional closing amount of the valve 600 of the corresponding heating room, heating is performed more efficiently.

In addition, when the valve 600 of the corresponding heating room R is equal to the set temperature and the current temperature in a state in which the current closing amount or the current opening amount is determined, the controller 700 is pre-stored or input from the outside. By comparing the reference temperature and the return water temperature measured at the valve 600 of the heating room R, if the return water temperature is lower than the return reference temperature, it is determined that the heat exchange is being actively performed, and By determining the additional opening amount, and controlling the corresponding actuator 610 to open the valve 600 of the corresponding heating room R by the additional opening amount, it is characterized in that the efficiency of heating can be increased do it with

That is, as in the opposite case described above, the controller 700 determines that heat exchange is actively performed because the return temperature is lower than the return reference temperature by increasing the flow rate of hot water when the current temperature is low and heat exchange is actively performed, This is to more efficiently maintain the state in which the current temperature of each heating room R has reached the set temperature.

In the example described above, when the current temperature of both heating rooms reaches the set temperature, the current temperature (30 degrees) is lower than the current temperature (24 degrees) of any one heating room is lower than that of any one heating room Accordingly, the difference between the return temperature and the return reference temperature recovered from any other heating room maintaining a low current temperature Because it is smaller than the car, that is, since the amount of heat exchanged is less in one of the heating rooms, if the return temperature is lower than the return reference temperature in consideration of heating efficiency, the current temperature is considered and the additional opening amount is determined.

At this time, the controller 700 indicates that efficient heat exchange is being performed when the return reference temperature and the return temperature are the same in a state in which the current closing amount or the current opening amount of the valve 600 of the corresponding heating room R is determined. It determines and controls the corresponding actuator 610 to maintain the current closing amount or the current opening amount.

On the other hand, the controller 700 is the heating room (R) after the set temperature and the current temperature of the corresponding heating room (R) is the same when the water exchange reference temperature is not stored in advance or is not input from the outside. It is characterized in that the return temperature measured by the temperature sensor 620 of the valve 600 of the It may be input, but more preferably, when the set temperature and the current temperature of the corresponding heating room R are the same, the set temperature, that is, the current temperature, is set as the water exchange reference temperature.

In addition, in general, the temperature of hot water for heating is supplied at about 50 degrees for efficient heating, and the temperature set as the indoor temperature in winter is 25 degrees or more and 35 degrees or less, so that heat exchange in the heating room (R) is not performed. It will be obvious that the temperature of the hot water made is lower than the temperature of the supplied hot water, and the set temperature is also set lower than the temperature of the supplied hot water, but it changes for each user or according to the use environment.

Conventionally, the temperature of the hot water supplied to the heating room is 50 degrees, the return reference temperature is preset to 40 degrees, and when the set temperature is 28 degrees, when the current temperature reaches the set temperature, it is higher than before the heating room starts heating. Since the heat exchange of hot water is small, the difference between the return reference temperature and the return temperature occurs, and accordingly, the change value of the return temperature becomes small. For example, if the initial return temperature is 30 degrees, when the current temperature reaches the set temperature, the return temperature becomes 35 degrees, and the change value due to the difference between the standard exchange temperature and the return temperature is reduced to 5 degrees to 10 degrees.

Then, the controller adjusts the amount of change, that is, when the change value due to the difference between the return water reference temperature and the return water temperature decreases, partially closes the flow control valve to adjust the opening/closing amount to reduce the hot water flow rate, and vice versa, that is, opening and closing If the amount of change due to the difference between the standard return temperature and the return temperature is increased by controlling the amount, the flow rate control valve is partially opened again to adjust the opening/closing amount to increase the hot water flow. In case of change, there is a problem that heating is not performed efficiently because the value of change due to the difference between the water exchange standard temperature and the water exchange temperature is different from the set value.

However, the controller 700 of the present invention does not set the return reference temperature in advance, and when the current temperature reaches the set temperature, the return temperature measured first is set as the return reference temperature, so that the return temperature and It is characterized in that the flow rate of hot water can be adjusted by comparing the water exchange reference temperature.

That is, the controller 700 of the present invention sets the return reference temperature when the current temperature reaches the set temperature as described above, so that the current temperature and the set temperature are used first before adjusting the flow rate of hot water using the return temperature. By adjusting the flow rate of hot water so that the current temperature of each heating room (R) can reach the set temperature within a short time and then the current temperature that has reached the set temperature can be maintained by using the return water temperature secondly, It realizes the effect of heating efficiently.

In addition, the controller 700 of the present invention can obtain a change amount of ± value when comparing the return water reference temperature and the return water temperature determined as described above, and accordingly, in the case of +, the valve 600 is closed to reduce the flow rate of hot water. In the case of -, by opening the valve 600 to increase the flow rate of hot water, heating is efficiently performed using the return water temperature that changes even when the temperature of the supplied hot water changes.

Specifically, the controller 700 determines the additional closing amount of the valve 600 of the heating room R corresponding to 15% when the return temperature is higher than the return reference temperature by 2 degrees or more, and the return standard When the return water temperature is lower than the temperature by 2 degrees or more, the additional opening amount of the valve 600 of the corresponding heating room (R) is determined to be 15%.

That is, the controller 700 of the present invention determines that a difference between the current temperature and the set temperature may occur when the return temperature is 2 degrees or more or less than the return reference temperature, and the opening and closing amount of the valve 600 is generated. (For example, the standard exchange temperature of 25 degrees, the exchange temperature of 27 degrees (when it is higher than 2 degrees) or 23 degrees (when it is lower than 2 degrees))

At this time, the controller 700 determines that the current temperature does not differ from the set temperature when the return temperature is less than 2 degrees higher or less than 2 degrees higher than the return reference temperature, and the return reference temperature and the return By determining that the temperature is the same and not adjusting the opening and closing amount of the valve 600 accordingly, energy is saved by not receiving hot water from the heating room R or the heating water supply source 100 that requires a larger amount of hot water make it possible

In addition, the controller 700 of the present invention determines the additional closing amount of the valve 600 of the corresponding heating room (R) as 30% when the return temperature is higher than the return reference temperature by 5 degrees or more, and the return When the return water temperature is lower than the reference temperature by 5 degrees or more, the additional opening amount of the valve 600 of the corresponding heating room R is determined to be 30%.

That is, the controller 700 of the present invention determines that the current temperature can deviate from the set temperature in a short time when the difference between the return reference temperature and the return water temperature, which is determined after the current temperature reaches the set temperature, is 5 degrees or more. By adjusting the opening/closing amount of 600 to 30%, the current temperature is not changed.

However, the controller 700 of the present invention, when the difference between the return reference temperature and the return temperature changes abruptly, that is, when the return temperature is higher or lower than the return reference temperature by more than 5 degrees, the current temperature is set from the set temperature. It is determined that the temperature is out and heating is performed with the opening/closing amount of the valve 600 based on the current (standby) temperature, so that the current temperature can reach the set temperature again in a short time.

In addition, in the state that the controller 700 of the present invention receives information on whether or not heating is performed during heating from only one of the plurality of controllers 500 , the set temperature of the corresponding heating room R is currently When the temperature is exceeded, the corresponding actuator 610 is controlled by determining the opening amount of the valve 600 of the corresponding heating room (R) as 100% until the set temperature and the current temperature are the same do.

In addition, the controller 700 of the present invention receives the setting received from any one of the controllers 500 among the plurality of controllers 500 in a state in which information on whether or not heating is performed is received from two or more of the plurality of controllers 500 . Only when the temperature exceeds the current temperature, the actuator 610 is controlled by determining the opening amount of the valve 600 as 100% until the current temperature and the set temperature of the heating room R are equal. do.

That is, the controller 700 of the present invention heats only one heating room (R) even if the first user heats only one heating room (R) or performs a plurality of heating rooms (R), that is, the valve ( When 600) is opened and hot water is supplied, the valve 600 is opened at 100% until the current temperature reaches the set temperature, thereby reducing the noise caused by the control of the flow rate of hot water and the boiler (in the case of individual heating) Not only can it prevent the non-firing phenomenon, but it also allows the current temperature to reach the set temperature in a short time, thereby saving energy.

In addition, the hot water heating system of the present invention is another embodiment, the supply temperature sensor 12 installed in the main supply pipe 10 to measure the temperature of the hot water supplied to each household from the heating water supply source, and the hot water supply pipe 300 . Installed, doedoe installed in the entry temperature sensor 310 and the hot water return pipe 400 for measuring the temperature of hot water just before supply to the corresponding heating room (R) of each heating room (R), that is, immediately before entering, In each heating room (R), heating is performed through heat exchange in the corresponding heating room (R), and an exit temperature sensor 410 for measuring the temperature of the hot water at the point of departure from the corresponding heating room (R) is further included. It is characterized in that it is configured.

The supply temperature sensor 12 measures the degree of heat loss from the heating water supply source 100 or the temperature of the hot water accurately supplied to the hot water for heating, and transmits it to the controller 700, so that the controller 700 Based on this, by determining the heat loss for each section using the measured values received from the entry temperature sensor 310 and the exit temperature sensor 410, the additional opening/closing amount of the valve 600 considering the heat loss for each section By determining, it is characterized in that more smooth heating can be achieved.

The section for each section is supplied to each heating room (R), is recovered again and is discharged to the outside of the household, from the hot water distributor 200 to any one of the heating rooms (R). The first section in which hot water is supplied to R), the second section through which hot water passes through any one of the corresponding heating rooms (R), and the hot water distributor 200 from the corresponding one of the heating rooms (R) again It is divided into a third section until it is recovered.

At this time, the second section of the section is a section in which hot water is actually heat exchanged for heating, and the first section and the third section are not sections in which heat exchange is performed for heating of any one of the corresponding heating rooms (R). Since the hot water supply pipe 300 and the hot water return pipe 400 installed in the inside are heated in a common space (normally corresponding to a 'living room'), the first section and the third section are a common space, that is, heating of the living room. The living room of the city household and at least one heated room (R) are to be considered in a heated state.

That is, the controller 700, which has received information on whether or not heating is performed during heating from any one or more of the plurality of controllers 500, firstly adjusts the opening and closing amount of the valve 600 using the current temperature and the set temperature, In the case of a heating room (R) other than the living room, only the heat loss of the second section is considered, that is, the temperature of the hot water measured by the exit temperature sensor 410 of the heating room (R) other than the living room is determined as the return temperature, In the case of the heating room (R) corresponding to the living room, the first section and the third section of the heating room (R), which is not the living room, in which the hot water supplied to the heating room (R), not the living room, is heat-exchanged, and corresponding to the living room Considering the heat loss of the second section (the first and third sections are included in the second section) of the heating room (R), that is, the supply temperature sensor 12 of the heating room R, not the living room, and The valve 600 additional closing amount considering the temperature difference between the entry temperature sensor 310 and the exit temperature sensor 410 corresponding to the living room (corresponding to the temperature sensor 620 built in the valve 600 in the living room.) By determining the temperature of the measured hot water as the return water temperature, heating is made.

In other words, in the case of a heating room (R) other than the living room, the controller 700 is not the temperature sensor 620 built in the valve 600, but the exit temperature installed at a point out of the heating room (R) other than the living room. Adjust the opening/closing amount of the valve 600 of the heating room (R) rather than the living room so that the temperature of the hot water measured through the sensor 410 can be used as the return temperature,

In the case of the heating room (R) corresponding to the living room, since the exit temperature sensor 410 corresponds to the temperature sensor 620 built in the valve 600, the exit temperature sensor 410 or the temperature sensor 620 measured through the The preset heating rate is set so that the temperature of hot water can be used as the return temperature, but the heating rate is preset in consideration of the temperature difference between the supply temperature sensor 12 and the entry temperature sensor 310 of the heating room (R), not the living room. After the current temperature and the set temperature become the same, when the opening/closing amount of the valve 600 is adjusted using the return reference temperature and the return temperature, the additional closing amount is added to increase the heating efficiency.

The additional closing amount calculated using the heating rate must take into account the environment of the heating room (R), such as the length of the pipe and the temperature of the supplied hot water, so a detailed description is omitted, and those skilled in the art can calculate the increase in the current temperature taking this into account. will be self-evident

At this time, the 'at least one of the plurality of regulators 500' means only one regulator 500 and thus the opening amount of the valve 600 can be 100%, meaning 'at least two regulators 500' It will be obvious, and the 'heating room (R) corresponding to the living room' means 'the heating room (R) in which the hot water distributor 200 is installed'.

As a result, in the present invention, in the valve with a built-in temperature sensor, the material of the body 626 of the temperature sensor 620 is made of a synthetic resin material, so that maintenance costs can be reduced, and the current temperature and By considering the set temperature and secondly, the standard temperature for exchange and the return temperature, it is possible to obtain the effect of making heating more efficient.

The above has been described with reference to a preferred embodiment of the present invention, and is not limited to the above embodiment, and a person of ordinary skill in the art through the above embodiment does not deviate from the gist of the present invention It can be implemented with various changes in
