i was all set to remove my air con today (its not worked for months) and i just noticed that the same belt that drives the aircon drives the alternator and that its the air con pump that tensions the belt.
You can remove it, you just have to get a new/smaller belt to drive your alternator.
I can't remember what size is needed (I have a underdrive pulley so my belt is different anyways), but the safest bet is to drive to a parts store, loosen up the alternator, take off the belt, take it in tell them you need one that is about 5-6" smaller, then try it out, if it doesn't fit go back in & get the appropriate size.
is it a usdm prelude? i guess it may be different if it wasnt a usdm but on the usdm ones it is definitely the alternater that adjusts the belt.. and when i removed my a/c like 3 weeks ago the belt size to go just around the alternater and crank pulley was a 37 5/8" belt.. and make sure you get the right ribbed belt(cant remember if it was 5 or 6 ribbed)
all this was on my h23 1992... h22s may be different, not sure tho
