A propane BBQ tank's cooling effect is due to the liquid propane warming and boiling to gas due to the lower pressure (when the valve is opened).
The same thing happens when you recharge the A/C of a car -- the refill bottle contains a liquid which boils/evaporates when the trigger is pulled (the refrigerant goes from high pressure to a lower pressure environment). This cooling effect is when you know the A/C system is being recharged properly.
