Title:
TEMPERATURE CONTROL METHOD FOR WARM WATER
Document Type and Number:
Japanese Patent JPH01276317
Kind Code:
A
Abstract:
PURPOSE:To instantaneously obtain the warm water having a set target temperature by carrying out the feedforward control when the discharge is started and when the set temperature is changed. CONSTITUTION:The opening amount of a mixing valve 4 which discharges the arm water having a set temperature can be operated from the temperature of the hot water and the water as well as a target set temperature. Therefore the warm water having a target temperature is instantaneously obtained by driving a pump 3 after the opening amount of the valve 4 is set at start of the discharge and at change of the set value. In other words, the feedback control is carried out in a normal working state and then the feedforward control is performed at start of the discharge and at change of the set temperature. As a result, the accurate control of temperatures is ensured in the normal working state and the warm having a target set temperature is instantaneously obtained at start of the discharge and at change of the set temperature.
