Moist air into the condenser helps to pull heat out of the system quicker - we're dealing with an air over tube/fin heat exchanger. It's the same premise as people spraying water over their intercooler on turbo vehicles.
Also, driving the compressor slower will not necessarily make it last longer. It'll be easier on it short term, but it'll be running more frequently. You'll have refridgerant passing through the evaporator slower, thus less cooling capacity (heat removal capacity) for your AC air blowing over its coil (heat exchanger).

VANOS killed M5 engine - totaled out 9/9/2011.
M5 currently in purgatory awaiting its fate...
1. either let go to insurance company and auctioned off for parts, OR...
2. purchased back and reborn with a Dinan stroker engine!
Option 2 please, DONE!
