Description

Freeze Poretection Method of Boiler Having Each Room Temperature Control Function}

The present invention relates to a method for preventing freezing in a boiler equipped with a temperature control function of each room, and more particularly, heating several rooms by using a single boiler having a main remote control capable of controlling the whole, but each room has a sub In the hot water / heating system where the remote controller is installed so that the user can freely set their own heating temperature and heating function in each room, when the freezing temperature is detected in the boiler body, it is installed on the heating pipe of each room. By opening all the valves and freezing operation to prevent freezing of each chamber, including the main body to prevent the leakage and heating due to the situation is invented in advance.

Recently, a hot water / heating system has been developed and widely used to perform heating / hot water for several rooms using a single boiler. Such a boiler is a multi-remote control, and the main remote control is used for heating / hot water operation and setting. In addition, a number of sub-remote controllers installed in the kitchen or other rooms can be displayed including operation and setting for heating.The main control unit in the boiler and sub-remote controllers in each room can display heating pipes and boilers in each room. Opening and closing of several valves provided between the heating water outlets of the main body, and each chamber control unit for transmitting and receiving the state between the remote control is provided.

Therefore, the user can set ON / OFF and temperature setting of the heating / hot water for the whole through the main remote control, and control and turn on / off the heating in the corresponding room arbitrarily through the sub remote control of each room. Can be.

On the other hand, the conventional freezing prevention method in such a hot water / heating system is configured to detect the ambient temperature through the temperature sensor in the boiler body to perform a body freeze prevention operation in the main control unit ignores the valve opening and closing state of each room.

However, when the user goes out with the sub-remote installed in each room in winter, the mode is turned off, all the valves already installed between the boiler body and the heating pipe of each room are closed. Even if the main controller detects the freezing temperature and operates the boiler in the freezing prevention operation mode, there is a problem in that the heating water is not circulated at all in the heating pipes of the room so that only the boiler is overheated and the freezing prevention of each room is not possible.

In addition, even in some chambers, if the valve is in a closed state, the heating water may not be circulated in the chamber during freezing prevention operation, and there is a concern that the heating drainage of the corresponding room may be freeze.

In other words, in the conventional hot water / heating system in which the individual remote control is performed through the sub-remote controller, the freezing prevention operation of the boiler according to the state of the main remote controller and the sub-remote controllers is not linked, and only simple on / off is performed according to the freezing detection of the main body. No measures were taken to prevent freezing of the rooms.

The present invention has been made to solve such a conventional problem, and when the freezing temperature is detected in the main body of the boiler is installed on the boiler main body and the heating pipe of each room ignoring the previous state for the sub remote control of each room To prevent the freezing of the chamber including the main body by automatically opening all the valves and freezing operation, it is possible to prevent the freezing in the boiler equipped with the temperature control function of the chamber that can prevent the leakage and heating impossibility. To provide.

The object of the present invention described above is to continuously detect whether the temperature in the main body and the heating water tapping temperature reach the freezing temperature by the main control unit in the boiler while the boiler is in operation. Forcibly open all the valves installed on the heating piping of each room and perform freeze operation until thawing, and then close all the valves again, and perform the freeze operation as described above. When the boiler on signal is input from either of the remote controllers, it can be achieved by stopping the freezing operation and performing heating operation according to the user's selection.

Therefore, when the freezing temperature is detected in the main body of the boiler, all valves are automatically opened and the freezing operation is performed, thereby completely preventing itself from freezing each chamber including the main body.

The third and fourth transceivers 31 and 32 for data communication with the main controller 2 and the respective sub-remote controllers 4 and various data inputted from each unit are used to perform a predetermined program. Thereafter, according to the result, each chamber central processing unit 34 generating a predetermined control signal to the valve driving unit 33 and between the boiler main body and the heating pipe 5 of the gig room in response to the output signal of the central chamber processing unit 34. Each chamber control part 3 which has a valve drive part 33 which performs the opening-closing function of the valves 7 installed in it;

Each room controller 3 is provided with a function of receiving and transmitting predetermined data, and is provided in a kitchen or each room, and is composed of several sub-remote controllers 4 which allow a user to arbitrarily operate and set heating.

2 shows a flowchart for explaining the method according to the present invention, whereby the freezing temperature detector 25 and the heating water tapping temperature detector 23 during the shutdown of the boiler by the central processing unit 24 in the main controller 2 are shown. Continually receiving an output signal of and continuously detecting whether the temperature in the boiler body and the tapping temperature have reached a freezing temperature (eg, outside air temperature ≤ 5 ° C or heating water tapping temperature ≤ 6 ° C);

When the freezing temperature is detected as a result of the above detection, a predetermined control signal is generated in the chamber control unit 3, and the central processing unit 34 in the chamber control unit 3 passes through the valve drive unit 33 to control the body 6 and the chamber. Forcibly opening all valves (7) installed on the heating pipe (5);

Thereafter, in response to the temperature detected by the main control unit 2, driving the circulation pump through the electric appliance driving unit 27 and performing a freezing operation such as burning a burner if necessary;

While the freezing operation is performed as described above, the tapping temperature detecting unit 23 and the freezing temperature detecting unit 25 continuously detect whether the freezing release temperature is detected, and at the same time, the sub remote control unit 4 of each room including the main remote control unit 1. Continually detecting whether a boiler on signal is input in any of;

Closing all the valves (7), stopping the freezing operation and waiting when there is no free signal input of the boiler as a result of the detection;

As a result of the detection, when the boiler on signal is input to any one of the sub-remote controllers 4 of each room including the main remote controller 1 during the freezing operation, the valves 7 of the chambers are opened and closed so as to return to the previous state. The step of performing a heating operation according to the user's selection in the stopped state; characterized in that consisting of.

Referring to the effect of the present invention made of such steps are as follows.

First, the first and second transceivers 21 and 22, the heating water tapping temperature detector 23, the freezing temperature detector 25, the central processing unit 24 and the electric appliance driving unit 27 is provided and the boiler body ( The main control unit 2 installed in 6) detects the freezing temperature through the freezing temperature detector 25 and the heating water tapping temperature detector 23 while the boiler is stopped.

That is, continuously detecting whether the temperature in a boiler main body is less than 5 degreeC, or a heating water tapping temperature falls below 6 degreeC, and there exists a possibility that freezing may occur.

As a result, when it is detected that the temperature in the main body has dropped to a freezing temperature (ie, outside temperature ≤ 5 ° C or heating water tapping temperature ≤ 6 ° C), the main control unit 2 controls each room control unit through the second transceiving unit 22. Since a predetermined control signal is output to 3), the central processing unit 34 in each chamber control unit 3 is installed on the main body 6 and the heating piping 5 of each room through the valve drive unit 33. The valve 7 is forcibly opened.

Of course, the chamber valve 7, which is already open before the boiler is stopped, will remain in that state and forcibly open only the valve in the closed state.

Thereafter, the main control unit 2 performs a freezing operation such as driving the circulation pump through the electric appliance driving unit 27 according to the tapping temperature of the heating water and burning the burner as necessary.

That is, when the tapping temperature of the heating water falls below 3.5 ° C, for example, the circulation pump is driven and the burner is ignited to heat the heating water. Heat prevents freezing.

On the other hand, during the freezing operation as described above, the main control unit 2 through the tapping temperature detector 23 and the freezing temperature detector 25 freeze release temperature (for example, outside temperature ≥ 8 ℃ or heating water tapping temperature) ≥ 10 ° C.) and whether the boiler on signal is input from any one of the sub-remote controllers 4 in each room, including the main remote controller 1 through the first and second transceivers 21 and 22. Will continue to be detected.

As a result of this detection, the heating water and the outside air are heated by the combustion of the burner and the operation of the circulation pump in the state that the on-signal of the boiler by the user's remote control is not input. If it is detected as early, the main control unit 2 outputs a predetermined control signal to each room control unit 3 through the second transmission / reception unit 22 as described above, and thus the central processing unit 34 in the room control unit 3. In addition, the valve driving unit 33 forcibly closes all the valves 7 installed on the main body 6 and the heating pipe 5 of each chamber, and of course, the main control unit 2 freezes previously performed. After stopping the operation, it enters the standby state.

On the other hand, when the driver generates the boiler on-signal via any one of the sub-remote controllers 4 of each room including the main remote controller 1 as a result of the detection as described above, the main controller 2 In (), the valves 7 in each chamber are opened and closed to return to the previous state, and the hot water and heating operation are performed according to the user's selection while the freezing operation is stopped.

Of course, the main control unit 2 stores the state information of the sub-remote controllers 4 of each room when the stop command of the boiler is input through the main remote controller 1, and the rooms including the main remote controller 1 as described above. When the boiler on signal is input through any one of the sub remote controllers 4, the valves 7 in each chamber are opened and closed to return to the previous state.

Therefore, the heating water supply according to the previous condition and conditions is automatically supplied only to the room in which the heating water supply is performed when the boiler is restarted after the boiler is stopped through the main remote controller 1.

As described above, according to the present invention, in the hot water / heating system having several sub-remote remote controllers in addition to the main remote controller and heating and hot water operation is performed using one boiler, when the freezing temperature is detected in the main body of the boiler, Ignoring the previous state of the sub remote controllers in each room, all valves installed on the boiler body and heating pipe of each room are automatically opened and freeze-proof operation is performed to prevent freezing of each room including the main body. It is a very useful invention that can prevent the leakage and heating due to the situation in advance, and also to prevent the overheating itself of the boiler body due to the non-heating of the heating water.
