Method for controlling heating system

Abstract

Provided is a method for controlling a heating system capable of uniformly heating the respective rooms by proportionally calculating heat supplies required by the respective rooms, even when the heat supplies required for heating the respective rooms are different from each other depending on indoor temperature conditions and external conditions of the respective rooms. The method for controlling a heating system adjusts flow rates of heating water supplied into the respective rooms by adjusting opening rates of a plurality of room valves installed on heating water pipes, characterized in that current temperature differences between temperatures set for the respective rooms and indoor temperatures measured in the respective rooms are calculated, and opening rates of the room valves of the other rooms, except rooms having the current temperature difference larger than a previously set temperature difference, are reduced.

Description

technical field [0001] The present invention relates to a method for controlling a heating system, more specifically, to a method for controlling a heating system capable of adjusting the flow of hot water according to the heating needs of each room to heat each room in a balanced manner. Background technique [0002] Typically, boiler systems include warm water distributors that distribute hot water to the various rooms to be heated. The warm water distributor receives water heated by the heat exchanger of the boiler through the hot water supply pipe to supply the heated water to the respective rooms. The supplied water transfers heat energy to the various rooms, where it is cooled and sent to the return pipe. The warm water distributor includes a room valve for adjusting the flow rate of hot water supplied to each room. [0003] Room valves are classified into three types according to the control method: open / close type, constant flow type, and proportional control type....

Problems solved by technology

However, the response characteristic is too slow to evenly control the heating of the individual rooms 30

[0016] That is, when the flow rate is adjusted by adjusting the opening ratio of the proportional control valve 42, the adjusted flow rate affects the temperature of the returned hot water, which is time-consuming, and therefore, it cannot be immediately determined whether the adjusted flow rate is appropriate

In addition, since the valves 42 respectively control a plurality of rooms 30 independently, a change in the flow rate of one room affects another room, and therefore, it is basically impossible to organically control the flow rates of the respective rooms 30 due to slow response characteristics.

[0017] Therefore, the traditional proportional control method cannot evenly control the heating of each room 30
