Ventilation system:

The formula for calculating the number of air changes in the ventilation aging test chamber is as follows:

among them:

N--gas exchange times, times/hours;

P1--the average power when the valve is closed, W;

P2--the average power when the valve is open, W;

T1--ambient temperature, °C;

T2--tank temperature, °C;

V--the internal volume of the ventilation aging test chamber, L;

D-- Ambient air density at the test, g/L.

Circulating air supply system:

1. Air supply mode: internal hot air circulation;
