Outdoor temperature reset control method for boiler using external network

Abstract

The present invention relates to a method for the compensation control of heating temperature in accordance with the outdoor temperature and for preventing icicles from being formed on an exhaust pipe, wherein the outdoor temperature is received from an integration server without the need for having a separate outdoor temperature sensor installed, and a system is constructed so as to be capable of communicating between a room controller to which a wireless communication module is mounted and the integration server.

1 . A compensation control method of a boiler according to an outdoor temperature using an external network comprising the steps of:
 (a) registering a room controller by transmitting a unique number of a room controller having a wireless communication module mounted thereto to an integration server through a wireless router, performing an authentication step of the unique number at the integration server and then storing the unique number to a database;   (b) a user or installer accessing the integration server through a terminal to input location information corresponding to the unique number of the room controller to the database;   (c) searching the integration server for the outdoor temperature information of an area where the room controller is installed and transmitting the outdoor temperature information to the room controller; and   (d) transmitting the outdoor temperature information received from the room controller to a boiler controller so as to perform compensation control of the boiler according to the outdoor temperature.   
     
     
         2 . The compensation control method as claimed in  claim 1 , further comprising the step of identifying location information of the room controller at the integration server using an IP address of the wireless router and storing the location information of the room controller to the database. 
     
     
         3 . The compensation control method as claimed in  claim 1 , wherein the compensation control of the boiler controls flow rate of a hot water supply by adjusting opening degree of a variable flow valve according to change in the outdoor temperature. 
     
     
         4 . The compensation control method as claimed in  claim 1 , wherein the compensation control of the boiler controls temperature of the heating water supply according to change in outdoor temperature using a variable constant (K-factor) value that is in accordance with a preset outdoor temperature. 
     
     
         5 . The compensation control method as claimed in  claim 1 , wherein the compensation control of the boiler switches a three-way valve to a hot water position when the outdoor temperature is below zero, so that an expansion tank can store thermal energy which can prevent freezing of an exhaust pipe.
