VAV-TYPE AIR CONDITIONING SYSTEM

摘要

A VAV-type air conditioning system (1) computes a motor-power-setting value (Wc) for a blower (22) from a present rotation speed (Na) of a blower (22), and a correlation between a motor power value (Ws) and a rotation speed (Na) of the blower (22) when a static pressure (P) at an air outlet (21b) of an air conditioning unit (2) equals a predetermined static-pressure setting (Pc). This VAV-type air conditioning system (1) performs a control for changing the rotation speed (Na) of the blower (22) so that the difference between the present motor-power value (Ws) of the blower (22) and the motor power setting (Wc) is reduced.
