Stupid fridge question

[ffutures]

Wearing my mad scientist hat again...

Just had the fridge-freezer delivered and they told me it has to sit for three hours before plugging in "because they don't use CFCs any more."

I knew that CFCs were banned, but I hadn't thought about what replaced them and why it would need so much longer to stand. I know that early fridges used ammonia, have they gone back to using that or is it something else?

Update Got home - fridge appears to be pretty cold, ditto freezer, so presumably working OK. I'll bung some frozen food in a little later, once I've checked the temperature. Now where did I put the freezer thermometer.

later Minus 18 - should be OK.

One of the CSI (IIRC Miami) episodes had a similar thing which I think they referred to as 'swamp air conditioning' or some such. Basically a big chunk of ice and an electric fan. Spoiler I guess ()

Swamp coolers are evaporative coolers that blow air past damp pads. They work well in the dry air of the West, but would be useless in Florida.
