METHOD FOR CONTROLLING AN ABSORPTION SYSTEM
A method for controlling an absorption system, comprising the step of performing slow open control for opening a control valve of a heat-source fluid feeding pipe connected to a regenerator at a predetermined speed and controlling the heat input at the time of start; wherein said control valve is qu...

| description | A method for controlling an absorption system, comprising the step of performing slow open control for opening a control valve of a heat-source fluid feeding pipe connected to a regenerator at a predetermined speed and controlling the heat input at the time of start; wherein said control valve is quickly opened up to a predetermined opening degree at the time of start and thereafter, said control valve is opened at said predetermined speed is provided. There is no loss in the starting time by improving an operation delay of a heat-source fluid control valve at the start of operations and it is prevented that the heat-source fluid is excessively supplied to the absorption system itself which has still a low temperature to affect an equipment-side boiler even after the valve fully opens. When a start switch is operated, a controller 30 controls a motor 37 for opening/closing the control valve 36 so as to quickly increase the opening degree of the control valve 36 up to 20%, thereafter increase the opening degree at an opening speed of 50%/min until the opening degree reaches 70%, and opens the control valve at a low speed of 7%/min up to 100% after the opening degree exceeds 70%. Therefore, overshoot is prevented and any trouble does not occur that the water vapor excessively enters a high-temperature regenerator 1 though high-temperature high-pressure water vapor is quickly supplied to the regenerator 1. |
