'circular cooler' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'criticise choice after carbon enters' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'choice' becomes 'option' (synonyms).
'after' is a charade indicator (letters next to each other).
'carbon' becomes 'C' (chemical symbol).
'enters' indicates putting letters inside.
'pan'+'option'='panoption'
'panoption' going around 'c' is 'PANOPTICON'.
