<p><P>PROBLEM TO BE SOLVED: To solve a problem wherein a conventional method of controlling air supply quantity in an air-conditioning target room requires time for damper control and thus, prompt response is difficult, in regard to a method of controlling air supply quantity in an air-conditioning target room such as a clean room. <P>SOLUTION: In the method of controlling the air supply quantity to keep the air supply quantity constant in the air-conditioning target room 3, dynamic pressure within an air supply duct 5 is measured in an air supply flow passage 4 between an air supply fan 2 for outside air etc. and the air-conditioning target room 3, and based on the pressure deviation, the air supply quantity is kept constant via a control device 8 by a pressure control damper 7. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
