Abstract

PURPOSE: To save power sonsupmtion required for operating exhaust fans of air conditioning system, by stopping the operation of all of exhaust fans of a plurality of air conditoners when it is not necessary to take in open air, and specifying the number of exhaust fans to be operated at the time when it is required to take in open air.
CONSTITUTION: In case that it is not necessary to take in open air 9, operation of all of exhaust fans 5, 5 of each air conditioners 1, 1 is stopped. In starting taking of open air 9 in this state, room pressure is raised beyond the upper limit of room pressure controller 14, if opening speed of open-air introducting dampers 3 is too high. Therefore, it is necessary to open the dampers 3, 3 at a low speed within a controllable range of controller 14. Further, number of exhaust fans 5 to be opened is determined such as to satisfy the equation (1) shown in the drawing, and electromagnetic valves 13, 13 are operated to open those dampers 4 associated with the operated exhaust fans. With such an arrangment, it is enabled to operate a necessary minimal number of exhasut fans corresponding to the amount of open air to be introduced and thus to reduce power consumption required for operating the exhaust fans.
