Air conditioners give you a sore throat?

For some reason I keep getting a minor sore throat, especially around my tonsils, and I think it is because of air conditioners. It’s not one specific air conditioner, I seem to get it from any of the ones that come through the wall/window if I stay in the room for a few hours.

Is this normal? why does this happen?
Air conditioning itself may contribute to infection with common cold viruses. The lining of the nose is covered with a thin layer of mucus which protects against infection. Since air conditioners extract moisture from the air they may cause some drying of the protective mucous blanket in the nose and predispose to infection. The cold air may also help viruses to establish a hold in the nose as they reproduce better in a cold nose.

Portable Air Conditioners without hoses?

I’ve seen portable air conditioners that don’t need a hose for the hot air outlet. Are they a waste of time? Surely they must blow the hot air into the room too.
I’v seen a number of models in a office building but the only worth wile ones arn’t really airconditioners…you just fill them with ice and it blows air accross it
