I don't know of a single refrigerant in common use which remains liquid at STP. Almost all of them evaporate very, very quickly at atmospheric pressure.
Indeed, the most common one in new equipment (these days) is R-134a. Which is the same thing that goes into the "canned air" commonly sold and used for cleaning computer gear, and is also the same chemical used in the more common forms of freeze spray (the difference being whether it is dispensed as a liquid via an internal dip tube, or as a gas by simple lack of a dip tube).
What were you going on about, again?
Oh, right. Clues.
