PURPOSE: A method for automatically controlling the heating temperature of each room in a room heating system is provided to uniformly maintain the temperature of each room regardless of the season. CONSTITUTION: A method for automatically controlling the heating temperature of each room in a room heating system is as follows. When the opening degrees of valves of rooms, in which heating on signals are inputted, are lowered proportional to a temperature difference of water circulated in each room, it is determined whether an automatic control key for heating temperature is turned on in real time(S1). When the automatic control key for heating temperature is turned on, the temperature of water circulated in each room is detected and is stored to a predetermined place(S2).

PURPOSE: An automatic operation control method of a boiler using detected temperature of tap water for determining seasons is provided to automatically operate the boiler with the temperature proper for seasons. CONSTITUTION: An automatic operation control method of a boiler using detected temperature of tap water for determining seasons is as follows. A CPU(Central Processing Unit) of a main controller determines whether an auto-function operation button of a room controller is turned on or not(S11). If the auto-function operation button is turned on, the temperature of tap water for determining seasons and room temperature are detected(S12). Control temperature of heating water comparing to present temperature of the tap water or room control temperature and control temperature for hot water are calculated using a pre-set table(S14). A combustion process of the boiler is operated corresponding to the calculated control temperature of heating water, the room control temperature, and the control temperature for hot water(S15). If the combustion process is operated, whether the temperature of the heating and hot water reaches preset temperature or not is determined. If the temperature does not reach, a step is returned to an initial step. If the temperature reaches, all processes are completed(S16).

PURPOSE: A heating source interlocking heating control method using an answer signal and a time control is provided to secure the stability of a system by operating a room con and a heating control valve using an answer signal and a time control. CONSTITUTION: A heating source interlocking heating control method using an answer signal and a time control comprise next steps. A controller decides whether a valve driver is the driver capable of the output of the answer signal or not(S11). If general drivers is a general driver cannot outputting the answer signal, it decides which room con inputs heating valve opening request signal for heating(S12). If the heating valve opening request signal is outputted, the existence of opened heating valve(S13). If the opened heating valve exists, the corresponding room with the open request is operated(S14). The heating valve of the corresponding room is open, if the opened heating valve does not exist(S15). If the waiting time is expired, the heat operation is performed by outputting combustion request signal in the heating source(S17).

PURPOSE: A heat control method using boiler heating water in a controlling system in each room is provided to increase a consumer's satisfaction and improve heating efficiency using a boiler. CONSTITUTION: A heat control method using boiler heating water in a controlling system in each room comprises following steps. A boiler is installed and a MICOM performs the testing working of the boiler. The number of the heating pipe flow metering valves which are opened for heating is counted. Whether the value of the opened heating pipe flow metering valve is 0 or not is confirmed. In case of "0", a heating off mode of the boiler is performed. In case the value of the opened heating pipe flow metering valve is not "0", a heating on mode of the boiler is performed. The target flow of each heating pipe is calculated according to the pipe length rate of each room connected corresponding to the number of the opened heating pipe flow metering valve(S6). Each heating pipe flow metering valve is opened according to the calculated target flow.
摘要:
A heat treatment apparatus and auto-tuning method for a control constant, and a storage medium are provided to tune a PID constant by resetting the PID constant with reference to a temperature profile. A reaction chamber(2) contains a process atmosphere and a target. Heaters(41,42,43,44) are installed in the reaction chamber to heat the process atmosphere. Temperature detectors(TC1,TC2,TC3,TC4) detect the process atmosphere which is heated by the heaters. A controller(7) controls the heaters through a PID control. The controller includes a rule table, an execution unit, and an updating unit. The rule table is prepared by matching an estimated variation amount and a variation rate of a PID constant. The execution unit acquires a temperature profile based on temperature detection values from the temperature detector and repeats a process for obtaining a difference between a measured value and a target value based on the temperature profile and a process for resetting the PID constant a variation rate corresponding to the estimated variation amount, until the difference satisfies a permissible range.
