Air con current test; redundant fans

27/03/08 | by Jeff [mail] | Categories: Temperature

Today's experiment was to determine the current drawn by our entire air conditioning system. With the system switched on, we were drawing a total of 252 amps on the three phases. With the system switched off, our consumption dropped to around 131 amps.

We also disconnected some fans in a network switch rack that were not doing anything useful:

There's not much point in having fans at the top of this rack when the side panels are missing! Each network switch box has its own fan anyway.
