Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for compensating outside temperature of a boiler using an external network,

The present invention relates to a method of controlling a boiler system according to an outside temperature provided from an external network, and more particularly, to a system for communicating between a room cone equipped with a wireless communication module and an integrated server, The temperature of the outside temperature of the boiler is controlled by controlling the set temperature according to the outside temperature by adjusting the amount of heat supplied and preventing an icicle from being formed in the exhaust gas even in the subzero weather. And more particularly, to a compensation control method.

Ondol heating can be divided into individual heating system, district heating system and central heating system. For the ideal control in Ondol heating, the heat gain and heat loss of the building should be the same. Heat acquisition and heat dissipation processes are dynamic processes that require frequent control of the amount of heat supplied to the room because they change from time to time due to outside temperature, solar radiation, soaking, and internal heat.

In the case of the individual heating, the temperature of the heating supply water is set by seasonally different standards, and in winter, it is generally set at 60-80 ° C. Although the effect of outside temperature is considered by season, it does not consider the effect of outside temperature change on the temperature setting of supplied heating water in the same season, There is a problem that an overheating phenomenon occurs and energy waste is often caused.

In order to solve such a problem, in the prior art 10-1109648, a supply line to which hot water is supplied; A hot water pipe for branching from the supply line to each room to allow heat exchange between the latent heat of the hot water and the corresponding room; A water return line communicating with the hot water line to return heat-exchanged hot water; An outdoor temperature sensor provided for measuring an outdoor air temperature; A control unit for receiving outside air temperature from the outside temperature sensor and outputting a control signal according to the outside air temperature; And a variable flow rate valve that is installed in the supply line or the water return line and receives a control signal from the control unit to adjust a flow rate of the hot water flowing in the pipe.

On the other hand, in general, in the case of a boiler, the air introduced through the air supply pipe from the outside is supplied to the burner together with the fuel by the blower, and the exhaust gas generated by the burning in the burner is circulated in the heat exchanger And then discharged through the exhaust port into the atmosphere outside the boiler.

The exhaust gas contains a considerable amount of water (H2O). Normally, the temperature of the exhaust gas is 100 degrees or higher. Therefore, the moisture contained in the exhaust gas can not be condensed and is discharged through the exhaust pipe in a steam state.

However, when the outside air temperature is very low, such as during the winter, the temperature of the exhaust end of the exhaust gas becomes very low, so that the exhaust gas temperature may become lower than the dew point temperature (the temperature at which the steam contained in the exhaust gas starts to condense, usually 40 to 55 degrees) In this case, the water vapor condenses at the exhaust end.

In this case, in the winter when the outdoor temperature is below zero, the condensed water condensed at the end of the exhaust pipe is frozen to form an icicle. Such an icicle is not very good in appearance, and human or material damage occurs when icicle falls from the upper floor of a high- There is a problem.

In order to solve such a problem, in the conventional patent No. 10-0805551, a boiler is operated to perform a combustion stroke; Determining whether an outside air temperature measured by the outside air temperature sensor is lower than a predetermined temperature; Switching the three-way valve to a hot water position when the measured outside air temperature is lower than the set temperature; Performing a fire extinguishing process of the burner when the temperature of the heating water pipe reaches a predetermined temperature; Circulating pump and blower are operated so that heat exchange occurs in the main heat exchanger and hot air is discharged through the exhaust pipe.

In the above-described related arts, a separate outside temperature sensor is required to be attached to the outside wall or the supply mechanism of the boiler for measuring the outside air temperature, and it is inconvenient to connect to the controller of the boiler.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

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

The method for compensating the outside temperature of the boiler using the external network according to the present invention comprises: (a) registering the room cone 110 of the boiler 100 in the integration server 130; (b) transmitting the outside temperature information from the integration server 130 to the room controller 110; And (c) performing outside air temperature compensation control in the boiler 100 using the outside air temperature information received from the room cone 110.

First, as shown in FIG. 1, a room controller installed in a home is equipped with a wireless communication module 111 so that wireless communication is possible, and a unique number is input for each product.

When the room controller 110 is connected to the wireless router 120 installed in the home, the wireless router transmits the unique number using wireless communication, and the wireless router receives the wireless number and transmits it to the integration server 130 again.

The integration server 130 is provided with an authentication server 131 and a database 135. The integration server 130 analyzes the received unique number and performs an authentication procedure to determine whether it is correct. When authentication is completed, 135).

The step of transmitting the outside temperature information to the room controller 110 in the integration server 130 can be performed by two methods.

First, the user or the installer inputs the address information. The user or the installer accesses the integration server 130 through the terminal 140 such as a smart phone, a PC, or a notebook computer, inputs the unique number, ), And the address information is stored in the database 135 together with the unique number. When the outside air temperature compensation control function is set in the room con- trol 110, the service server 132 for searching and updating the outside air temperature in each region of the country in real time searches for the unique number and address information of the room con- tention 110, Real-time outdoor temperature information of the area is transmitted to the room controller 110.

The integration server 130 extracts the IP address of the wireless router 120 that has performed the wireless communication with the room controller 110 and transmits the extracted IP address to the Korea Internet Information Center //), and stores the corresponding location information in the database 135. The process of transmitting the outside temperature information to the room cone 110 is the same as that described above.

The room controller 110 receiving the outside temperature information through the above steps transmits the outside temperature information to the control unit 101 of the boiler 100 by a wired communication method such as RS485 to perform compensation control according to the outside air temperature.

Although the room temperature 110 is shown as an essential component in the process of transmitting the outside temperature information from the integrated server 130 to the control unit 101 in the above description, the room temperature 110 transmits / Such as, for example, panels attached to a boiler, and the like.

Compensation control according to the outside temperature has been proposed in various forms in the prior art. In this case, control for increasing the energy efficiency by adjusting the amount of heat supplied according to the outside temperature and for preventing the formation of icicles in the exhaust gas when the outside temperature is below zero An embodiment related to control will be described.

First, both the flow control method and the heating supply water temperature control method are available for controlling the amount of heat supplied according to the outside temperature.

As shown in FIG. 2, the outdoor air flow rate control apparatus includes a supply pipe 210, a hot water supply header 220, a hot water pipe 230, a hot water return header 240, a water pipe 250, 101, and a variable flow rate valve 260.

The hot water pipe 230 is branched from the hot water supply header 220 to allow heat exchange between the latent heat of the hot water and the corresponding room. The hot water pipe 230 performs heat exchange with the floor in the process of flowing along the hot water pipe 230, And then the hot water is cooled down and returned through the hot water return header 240.

The control unit 101 receives the outside air temperature information output from the room cone 110 and outputs a control signal according to the outside air temperature to control the variable flow control valve 260.

The variable flow rate valve 260 is installed in the supply pipe 210 or the water return pipe 250 and receives a control signal from the control unit 101 to control the flow rate of the hot water flowing in the supply pipe 210 or the water return pipe 250 .

That is, when the outside air temperature rises, the controller 101 controls the variable flow rate valve 260 so that the flow rate of the hot water is decreased, so that the flow rate of the hot water supplied is decreased and the heat exchange time becomes more sufficient As a result, the thermal efficiency is increased.

Meanwhile, the heating supply water temperature control method according to the outside temperature is performed by the control unit 101, which receives the outside air temperature information output from the room air conditioner 110, and supplies the outside air temperature according to a predetermined K- The heating control temperature is determined by determining the water temperature. The heating supply water temperature determined here is limited to a maximum of 80 degrees, and the boiler operation is stopped when the temperature is less than 30 degrees. This makes it possible to reduce unnecessary heating energy consumption as compared with the conventional proportional control method.

FIG. 4 is a graph showing a relation between an outside temperature and a heating supply number set temperature according to a commonly used K-factor value. The K-factor is a value calculated by applying a compensation factor according to the outside temperature, However, it can be changed by the installer or the user.

Next, referring to FIG. 3, a control method for preventing icicles from forming in the exhaust passage of the boiler will be described.

First, the boiler is operated to perform the combustion stroke. The control unit 101 switches the three-way valve 390 to the hot water position when the outside air temperature provided by the room cone 110 reaches 0 占 폚, which is the temperature at which the condensed water at the distal end of the exhaust pipe 360 can freeze. So that the heating water flows to the hot water heat exchanger 380 side. In this case, the combustion process performed in the existing burner 330 is maintained in this state

In this case, the heating water circulates through the closed circuit composed of the circulation pump 350, the main heat exchanger 340, the three-way valve 390, the hot water heat exchanger 380 and the expansion tank 370 by the operation of the circulation pump 350 It is preferable that the heating water has a flow path structure that passes through the expansion tank 370.

That is, the expansion tank 370 can store about 4 to 8 liters of heating water. When the three-way valve 390 is switched to the hot water position, when the combustion is performed, the heating water circulated through the closed circuit is heated The tank 370 has a function of storing heat energy that can prevent formation of ice at the end of the exhaust pipe 360.

The temperature of the heating water flowing in the pipe is detected by a heating water temperature sensor (not shown), and the control unit 101 determines whether the measured heating water temperature has reached a preset temperature, It is judged that the temperature at the end of the exhaust pipe 360 can be prevented from freezing and the fire extinguishing process is carried out.

Here, the heating water temperature set in advance for carrying out the extinguishing stroke of the burner 330 is raised in the heating water circulation closed loop including the expansion tank 370 in a state where the three-way valve 390 is switched to the hot water position It is preferable that the temperature is the maximum possible. Usually, the temperature of the heating pipe inside the boiler can be raised to about 80 to 85 degrees, but if the flow path structure in which the heating water is circulated is specified, the maximum temperature can be determined by the experiment.

The circulation pump 350 and the blower 320 are operated and the air conveyed by the blower 320 undergoes heat exchange with the heated water heated by the above process in the main heat exchanger 340, And this air is brought into contact with water vapor or condensed water at the end of the exhaust pipe 360 when it is discharged to the outside along the exhaust pipe 360, thereby preventing freezing.

The embodiments of the external temperature compensation control method of the boiler using the external network of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent implementations You can see that examples are possible. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims. It is also to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
