I found this explanation on the our cool house web site.

When I was trained to fast-fill SCUBA tanks, I was told to always put the tank
in a big bucket of water, to keep the steel tank from over-heating.
I asked my boss, "is the steel expanding and getting hot"?
He said, nope, it's the atoms inside the tank being forced together so hard.
They are rubbing against each other, producing friction heating.
Since we used large air tanks to fill the SCUBA tanks, with the compressor off,
it's electric motor heat wasn't contributing to the hot air in the SCUBA tank.
I can see how the motor's heating is going to put some BTUhs into the R410A,
but the amount seems too small to account for the
difference in pumped BTUs (heat vs cool).
1 watt hour of motor heat equals 3.412 BTUh.
5,000 BTUh of extra heating from the motor heat, means it would be
producing 1.465 kWh in heat losses.. That would blister the paint..
