DEFINITION

Classification: 95/288

HEAT EXCHANGING:

(under the class definition) Process in which there is transfer of heat.

(1) Note. The heat transfer steps must be part of a larger process containing subject matter for Class 95. If the only separation involved is conducted by indirect heat transfer steps, then classification in Class 165 is proper. However,

Class 95 does take cold wall-hot wall thermal diffusion and condensing a constituent of a gas to the solid state.
