It is separated and composed by a heat exchanger for use. Of course, the present invention is not limited thereto, and it may be configured to supply hot water for heating and hot water supply through the one heat exchanger according to the connection state of the heat exchanger and the pipe.

A control method for minimizing the heat loss of the saving system boiler configured as described above is as follows.

The saving system boiler control method includes a boiler ON step (S1), a heating hot water setting step (S2), a deviation temperature setting step (S3), a burner operation step (S4), and a deviation temperature arrival confirmation step ( S5), proportional heating hot water heating step (S6), heating hot water setting temperature reached confirmation step (S7), burner operation stop step (S8), boiler operation maintenance check step (S9), and boiler off (OFF) ) Step (S10).

The boiler ON step (S1) is a step of supplying power to the saving system boiler to maintain the boiler ON state when heating or hot water is to be used through heating hot water.

In the control method, the heating hot water setting step (S2) is performed by the user or the administrator (hereinafter collectively referred to as the'user') when the boiler is turned on through the boiler on step (S1). This is the step of setting the temperature.

In this case, an appropriate temperature to be used through the boiler (hereinafter collectively referred to as'set temperature') is set through a control panel (not shown) configured on one side of the main body 110. For convenience of explanation, it is assumed that the preset temperature of the heating and heating water is '50℃'.

The deviation temperature setting step (S3) is a step of setting the deviation temperature when the setting of the set temperature is completed through the heating hot water setting step (S2).

This sets the deviation temperature through a control panel configured on one side of the main body 110 according to the user's judgment or request according to the purpose of use or the installation environment of the boiler. In this case, assuming that the deviation temperature is 10°C, the deviation temperature is recognized in the range of 41 to 49°C corresponding to -10°C from the set temperature of 50°C.

In this case, the deviation temperature is preferably set to have a ratio of 10 to 100% based on the set temperature. That is, if the set temperature is 50°C, the deviation temperature is preferably set in a temperature range of 5 to 15°C.

In the burner operation step S4, when the setting of the deviation temperature is completed through the deviation temperature setting step S3, the burner is started.

That is, when the setting of the range of the set temperature and the deviation temperature is completed, the operation of the boiler, that is, the operation of the burner 120 is started according to the current temperature of the heating hot water.

In this case, the temperature of the heating hot water is determined through a sensor value measured through the sensor 139 of the heat exchanger 130 configured at the upper end of the main body 110, that is, the temperature. For example, when the temperature measured by the sensor 139 exceeds 50° C., the boiler, that is, the burner 120 is not operated, and when the temperature is less than 50° C., the burner 120 is operated. For convenience of explanation, it is assumed that the temperature measured through the sensor 139 is '30°C'.

When the burner is operated through the burner operation step (S4), the heating hot water is heated by the operation of the burner, and the temperature of the heating hot water thus heated reaches a predetermined deviation temperature. This is the step to check whether or not.

That is, heating of the heating hot water is performed through the heat exchanger 130 and the waste heat recovery device 140 configured at the upper end and one side of the main body 110 by the operation of the burner 120, and the temperature of the heating hot water thus heated. Check whether the value reaches the lowest value of the deviation temperature.

For example, 100% operation of the burner 120 causes an increase in temperature as the heating hot water of 30° C. is heated for the first time, and at this time, 41° C. corresponding to the lowest value in the range of the preset temperature range of 41 to 49° C. Check if you have reached

If the sensor value measured through the sensor 139, that is, the temperature has not reached the minimum value of the deviation temperature, the burner 120 continues so that the heating hot water can quickly reach the minimum value of the deviation temperature through 100% combustion. Combustion occurs.

In the proportional heating hot water heating step (S6), when the temperature of the heating hot water reaches the set range of the deviation temperature through the deviation temperature arrival confirmation step (S5), the combustion amount of the burner and the water outlet flow rate of the water outlet passage are proportionally adjusted. This is a step to quickly reach the set temperature while minimizing heat loss.

In addition, the proportional heating hot water heating step (S6) includes a burner combustion amount adjusting step (S62), a heating hot water outlet amount checking and adjusting step (S64), and a heating hot water temperature measuring step (S66).

In the burner combustion amount control step (S62), when the heating hot water reaches the minimum value of the deviation temperature, the combustion of the burner, that is, the flame is controlled to optimize the gas consumption according to the temperature value of the heating hot water.

For example, in a conventional boiler, assuming that the initial heating temperature is 30°C and the set temperature is 50°C, the burner burns 100% of the heating temperature from 30°C to 50°C, and then at the set temperature 50°C. When the temperature drops to 49° C., 100% combustion is again performed in the burner.

Through this, the fuel consumed by the initial start of the burner due to 100% combustion in the burner, that is, the gas for 100% combustion, is made regardless of the temperature deviation of the heating hot water, and accordingly, the fuel consumption of the burner is compared. There is a problem in that heat loss is caused as the thermal efficiency obtained is rather lowered.

In contrast, in the present invention, when the range of the deviation temperature is reached, the combustion amount of the burner is differentially increased or decreased according to the temperature value of the deviation temperature, thereby minimizing heat loss by maintaining the optimal state of thermal efficiency relative to the fuel consumption.

For example, in the present invention, the combustion amount of the burner is applied differentially according to the temperature value of the heating hot water, such as 90% of the combustion amount when the heating hot water is 41°C, 80% when the heating temperature is 42°C, and 70% when the 43°C It is possible to implement a saving system that can achieve fuel saving effect by minimizing the consumption of the product.

In the step (S64) of checking and adjusting the amount of heating hot water, the amount of hot water discharged through the water supply passage is checked according to the user's use of the heating water, and the opening/closing amount of the flow control valve configured on one side of the water supply passage is adjusted according to the amount of water. Thus, it is a step of maintaining the water outlet pressure of the heating hot water by adjusting the circulation pressure of the circulation pump configured on one side of the water return passage and the opening and closing amount of the flow control valve.

That is, as the conventional boiler does not have a separate flow control valve, there is a problem in that energy consumption increases as the circulation pump is operated 100% according to the user's use of heating hot water.

In addition, in the conventional boiler, the heating hot water is discharged at a high flow rate through the water discharge channel by the operation of 100% of the circulation pump, so that the time spent in the heat exchanger and the waste heat recovery device for the heating hot water is shortened, and thus , There is a problem that the heating efficiency of the heating hot water decreases due to heat exchange.

In contrast, the present invention controls the opening and closing amount of the flow control valve 250 configured on one side of the water outlet passage 210 and the circulation pressure of the circulation pump 232 according to the user's amount of heating hot water. While having a water outlet pressure, by minimizing the flow rate of the heating hot water discharged through the water outlet passage 210, the time that the heating hot water stays in the heat exchanger 130 and the waste heat recovery device 140 is delayed. It improves the heat exchange efficiency of heating hot water. In this way, the heat exchange efficiency according to the delay in the residence time of the heating hot water is improved, and as a result, the time for the heating hot water to reach a set temperature is shortened to minimize heat loss.

In the heating hot water temperature measuring step (S66), a reference value for adjusting the opening/closing amount of the flow control valve is provided according to the temperature of the heating hot water discharged through the hot water supply channel by measuring the temperature of the heating hot water.

As described above, the burner combustion amount control step (S62), the heating hot water outlet amount check and control step (S64), and the heating hot water temperature measurement step (S66) are not performed part by part, but are proportional heating through an organic interlocking relationship. By heating the hot water, the consumption of the fuel consumed before the heating hot water reaches a set temperature and the corresponding heat loss are minimized, so that a saving system with a fuel saving effect is achieved.

That is, by controlling the combustion amount of the burner according to the temperature value of the heating hot water, and controlling the amount of hot water discharged through the water outlet channel according to the amount of heating hot water, the heating hot water stays in the heat exchanger and the waste heat recovery device. By delaying the time required for heating, the time to reach the set temperature for the heating hot water is optimized compared to the fuel consumption.

In the step (S7) of confirming that the heating hot water reaches the set temperature, proportional heating of the heating hot water is performed through the proportional heating hot water heating step (S6), and it is a step of determining whether the heated hot water has reached the set temperature.

In this case, if the temperature of the heating hot water has not reached the set temperature, continuous proportional heating is performed, and when the set temperature is reached, the next step is performed.

In the burner operation stop step (S8), when the heating hot water reaches the set temperature through the heating hot water setting temperature reaching step (S7), combustion of the burner is stopped to prevent heat loss due to unnecessary combustion.

The boiler operation maintenance check step (S9) is a step of confirming whether the boiler is continuously used when the burner is stopped through the burner operation stop step (S8).

In this case, if "Yes" to continue using the boiler, it moves to the deviation temperature arrival confirmation step (S5) and determines whether the heating hot water reaches the deviation temperature from the reached set temperature, and the deviation temperature arrival confirmation step The subsequent process of (S5) is cyclically repeated in the process as described above, and continued use of the boiler is maintained.

Or, if you "no" to stop the continued use of the boiler, it moves on to the next step.

The boiler off step (S10) is a step of stopping the operation of the boiler if it is "No" through the boiler operation maintenance check step (S9).

On the other hand, the boiler implementing the saving system boiler control method as described above can be controlled remotely or in real time through a smartphone or a dedicated terminal owned by an authenticated user or manager through an IoT. , It minimizes heat loss and provides convenience of control.
