Section Scope

Heat transfer devices of the type generally used in mechanical refrigeration as outlined in the subsection scopes.

Air Cooled and Evaporative Condensers Subsection Scope

Air Cooled and Evaporative Condensers primarily, but not exclusively, using ammonia based refrigerants.

For Reference: Air cooled refrigerant condensers, remote type, which consists of a condensing coil, a means for air circulation (including drive if furnished), frame and enclosure.

Evaporative condensers which consist of a condensing coil, spray system and pump (if furnished), a means for air circulation (including drive if furnished), frame and enclosure.

Liquid to Liquid Heat Exchangers Subsection Scope

Heat transfer devices used to exchange heat between two fluid streams that are single phase liquids:

  1. Plate-type heat exchangers
  2. Shell-and-tube heat exchangers, shell-and-U-tube heat exchangers and shell-and-coil heat exchangers
  3. Tube-in-tube heat exchangers
Liquid to Refrigerants Heat Exchangers and Liquid Receivers Subsection Scope
  1. Shell-and-tube, shell-and-U-tube, tube-in-tube, and shell-and-coil condensers
  2. Shell-and-tube, shell-and-U-tube, tube-in-tube, and shell-and-coil liquid coolers
  3. Liquid suction heat exchangers
  4. Liquid receivers
  5. Plate-type heat exchangers
Industrial Unit Coolers Subsection Scope

Unit Coolers primarily using ammonia based refrigerants.

For Reference: A unit cooler is a factory-made assembly, including means for forced air circulation and elements by which heat is transferred from air to refrigerant without any element external to the cooler imposing air resistance. These may also be referred to as Air Coolers, Cooling Units, Air Units or Evaporators.
