HEAT EXCHANGERS; TERMINOLOGY
01-11-1997
12-01-2013
Purpose of this standard is to establish a heat exchanger terminology so that consistent terms are used. For the purposes of this standard a heat exchanger is a device, the main function of which is to transfer heat between two fluids, with physical separation by a wall. Heat exchange between a fluid and a solid material (in the case of ovens in particular) is therefore excluded.
