| titleOfInvention | How to detect the failure of opening / closing valve of heating pipe of each boiler using overheat prevention function |
| abstract | The present invention relates to a failure detection method for opening / closing valves for heating heating pipes of a boiler using an overheat prevention function. In particular, in a known overheating operation control method for each room control system, a boiler enters an overheating and boiling prevention operation mode. Then, the microcomputer in the controller checks the number (i) of the rooms having the heating mode "on" state among several remote controllers and increments the number "n" of the room to be checked having the initial "0" state by "1". Steps; Open all heating pipe open / close valves installed in the heating pipes of each room to dilute the heating water to a uniform temperature, and continue to operate the circulation pump of the boiler for a predetermined time so that the heating water having a certain temperature circulates and dilutes all the heating pipes. Wow; If the circulating pump stops after being driven for a predetermined time, all other heating piping on / off valves are closed, and only the heating piping on / off valves corresponding to the number of inspection target rooms (n) determined by the increment of “1” are opened and the boiler is opened. Performing a combustion operation of the; Determining whether the heat exchanger tapping temperature of the boiler is lower than an overheat (boiling) temperature which is a reference value; As a result of the above determination, if the tapping temperature is higher than the reference value, an error is displayed on the display unit of the remote controller installed in the corresponding room, and the number of rooms to be heated (i) and the previous increment as before when the tapping temperature of the heat exchanger of the boiler is lower than the reference value. Determining whether or not the number n of rooms to be checked as a result is equal to; As a result of the above determination, it is determined whether the number (i) of the rooms in the heating mode "on" state and the number (n) of the room to be checked previously incremented are equal to each other. Returning to the step of detecting, and if i = n state, detecting whether there was no room where an error occurred; If there is no room where an error occurs as a result of the above detection, it is recognized as a failure of the boiler itself and a boiler check mark is displayed on the display of the controller. Giving step; characterized in that consisting of.n n n Therefore, when the overheat prevention error (or boiling error) of the boiler occurs, it is possible to distinguish between the failure of the boiler itself and the failure of each heating piping open / close valve or AIR PURGE in each room control system, thereby providing after-sales service (A / S). Not only can it be easily implemented, but it can also greatly improve the merchandise and reliability of the boiler itself.n n n n Control of each room, prevention of overheating (boiling), opening and closing valve of heating piping |
