1 Refrigerating systems are divided into classes, descriptive of the method employed for extracting heat as follows:

Direct system is one in which the evaporator is in direct contact with the material or space refrigerated or is located
In air circulating passages communicating with such spaces.

Indirect system is one in which a liquid, such as brine or water cooled by the refrigerant, is circulated to the material
or space refrigerated or is used to cool air so circulated.
