より、温度の行き過ぎ量が押えられる。The operation of the temperature controller configured as described above will be explained below using FIG. 2. The temperature controller 1 measures the indoor temperature by the temperature measuring means 2 using the temperature sensor 7, and compares the measured value of the indoor temperature with a preset indoor temperature setting value by the opening control means 3, The opening degree of the cold/hot water valve 8 is controlled based on the deviation. At this time, if the operation is started from the indoor temperature state at time a, the cold/hot water valve 8 begins to open, the indoor temperature rises, and the cold/hot water pulp 8 begins to close at the time b when it exceeds the set value. However, since the indoor temperature is delayed with respect to the operation of the cold/hot water valve 8, the indoor temperature rises to point C and starts to fall from there, and at point d when the indoor temperature falls below the set value again, the cold/hot water valve 8 closes. It begins to open. At this time, the maximum temperature detection means 4 detects the maximum temperature during this period from the measured value of the indoor temperature, and the upper and lower limit setting means 6 determines the upper limit of the valve opening based on the deviation between the set value of the indoor temperature and the maximum temperature. Set. As a result, the cold/hot water valve 8, which has started to open again, reaches the upper limit at time 0 and maintains its opening in that state, and begins to close at time q when the indoor temperature exceeds the set value again, but the pulp opening By being controlled, the amount of excessive temperature can be suppressed.

がシ過ぎを押える。On the other hand, by detecting the lowest temperature after time b (time f) from the measured value of the indoor temperature by the lowest temperature detection means 6, the upper and lower limit setting means 6 detects the difference between the set value of the indoor temperature and the minimum temperature. Set the lower limit of the μ-pu opening to prevent it from opening too much below the room temperature.

By setting the upper or lower limit of the pulp opening degree based on the deviation and constantly correcting excessive valve operation,
This has the effect of allowing stable temperature control under any indoor load conditions.
