Producing or causing cold; able to generate freezing or very low temperatures.
From Latin 'frigor' (cold) plus '-fic' (from 'facere,' to make). A scientific term especially used in 18th-19th century physics and chemistry literature.
Early scientists used 'frigorific' to describe anything that made things cold before they understood refrigeration—they'd call ice-making 'frigorific power,' imagining cold as a real force!
