摘要： PROBLEM TO BE SOLVED: To safely close valves without causing damage in a room when shutting valves used for air volume control to a shut-off position simultaneously.SOLUTION: A room pressure control system includes: an air supply valve which adjusts air volume of air supply; a general exhaust valve which adjusts air volume of exhaust; a local exhaust valve which adjusts exhaust air volume of a local exhaust device installed in a room; air volume control units (2-4) which, when starting a simultaneous shut-off control operation, controls the air supply valve, the general exhaust valve and the local exhaust valve, and decreases the air supply volume, the exhaust air volume and the local exhaust air volume while maintaining the air volume of the difference in which the sum of the exhaust air volume and the local exhaust air volume is subtracted from the air supply volume always constant; and shut-off control units (8-10) which shut the air supply valve, the general exhaust valve and the local exhaust valve simultaneously to a shut-off position when the air supply volume, the exhaust air volume and the local exhaust air volume become equal to or less than the minimum air volume.

摘要： PROBLEM TO BE SOLVED: To provide a room pressure controlling system extending the service life of a valve having a PCV (Positive Crankcase Ventilation) function, and extending the operating time and maintenance cycle of the whole system.SOLUTION: This room pressure controlling system includes a local exhaust valve EXV, an air supply valve MAV, a general exhaust valve GEX, controllers 105, 106, 107, and a differential pressure sensor 109. The controller 107 calculates a correction control output value with respect to one actuated as a room pressure control valve of the air supply valve MAV and general exhaust valve GEX based on room pressure measured by the differential pressure sensor 109 and a set value. The controller 107 determines whether or not at least one of supply air volume and exhaust air volume is being changed. If air volume is being changed, the controller 107 performs control calculation emphasizing readiness of room pressure control more than a reduction in the number of operation times of the room pressure control valve. If the air volume is being stabilized, the controller 107 performs control calculation emphasizing the reduction in the number of operation times of the room pressure control valve more than the readiness of the room pressure control.
摘要翻译：要解决的问题：提供一种延长具有PCV（积极曲轴箱通风）功能的阀的使用寿命的室内压力控制系统，并延长整个系统的运行时间和维护周期。解决方案：该室内压力控制系统包括局部排气阀EXV，供气阀MAV，通用排气阀GEX，控制器105,106,107和差压传感器109.控制器107计算校正控制输出值相对于作为空气供给阀MAV的室内压力控制阀和基于由压差传感器109测定的室内压力的一般排气阀GEX而动作的一个设定值。控制器107确定供气量和排风量中的至少一个是否正在改变。如果风量改变，则控制器107进行强调室内压力控制的准备的控制计算，而不是减少室内压力控制阀的操作次数。如果空气量稳定，则控制器107执行强调室内压力控制阀的操作次数减少超过室内压力控制的准备的控制计算。版权所有（C）2013，JPO＆INPIT
