Abstract

PURPOSE: To facilitate control of an object room for circulation by providing a resistor between a place where an air quantity distribution control mechanism is installed in a circulating air passage and an induction air passage connector in an apparatus which provides an exhaust passage and a fresh gas induction passage in the midway of a circulation air passage.
CONSTITUTION: An air-conditioning room 1 as a circulation object room is connected with an air supply fan 3 through an air passage 2A and with an air return fan 6 through an air passage 2E. The supply fan 3 is connected with an air-conditioner 4 through an air passage 2B and the return fan 6 is connected with an air-conditioner 4 through a distribution damper 5 and air passages 2C, 2D as an air quantity distribution control mechanism. The air-conditioner 4 is connected with an induction air passage 8 for inducing fresh gas through a filter 9 and the induction air passage 8 is connected with the middle of an air passage 2C in place of the old connecting method indicated by a broken line. A resistor 14 for an air passage with a movable wing 14A provided in the air passage between the connecting point and a branching damper 5.
