Method for measuring the ventilation rate of ventilation type aging test box
The measurement method of the ventilation rate of the ventilation type aging test box:
1 Seal all ventilation holes, doors, thermometer holes and the gap around the blower (most surfaces can be effectively sealed with pressure-sensitive tape. If it is not close to the blower shaft, the blower must be covered and sealed), connect the standard electric meter Aging box power system.
2 Control the temperature of the working room of the ventilating aging test box to be 80 ± 2 ℃ higher than the ambient temperature. The temperature in the working room is measured by the central test point. The ambient temperature is 2m away from the aging box and at least 1m away from other objects around , And the position of the air inlet of the aging box is almost equal to the horizontal plane.
3 When the temperature of the test point in the working space reaches the control temperature for the first time to stabilize for 2h, measure the power consumed by the aging box within 30min.
4 Remove all the seals, open the ventilation port and vent, and measure the power consumed by the aging box within 30 minutes according to the method described in 6.4.1.2 ~ 6.4.1.3 (if the ventilation volume does not reach the specified range, it can be readjusted Vent)
