Page 25: Failure Analysis
Failure analysis Failure Analysis 5-1 Low Air Flow Rate The actual static pressure needed in the outside of the unit is greater than the design static pressure and the air flow rate is turned into the static pressure. Thus, the air flow rate is lower than the normal. The loose belt reduces the rotation speed of the fan, resulting in a low air flow rate. - Page 26 YORK Guangzhou Air Conditioning & Refrigeration Co.,Ltd.
