Abstract

PURPOSE:To have no influence for other rooms even if an air quantity of each room is regulated individually by regulating the air quantity of a fan so that the static pressure in a distribution chamber for feeding air-conditioning air in a plurality of rooms from an air-conditioning unit equipped with the fan and a heat exchanger. CONSTITUTION:Air-conditioning air is fed in each room 5 through a main duct 4 from an air-conditioning unit 1 equipped with a fan 2 and a heat exchanger 3. According to thermostats 8 the opening of dampers 6 of each room 5 is regulated individually and temperatures are controlled. The static pressure of a distribution chamber 11 is fluctuated by air quantity regulation, but it is regulated so that the air quantity from the fan 2 in accordance with the detecting values of a pressure detector 4 is controlled by an invertor and the static pressure becomes constant. Therefore, the air quantities for the other rooms are not changed even if the opening of dampers 6 is changed to modify the quantity of the air-conditioning air and the influence for the temperature is eliminated.
