The Trane Company believes that it is incumbent on manufacturers to serve the
industry by regularly disseminating information gathered through laboratory
research, testing programs, and field experience.
The Trane Air Conditioning Clinic series is one means of knowledge sharing. It
is intended to acquaint a nontechnical audience with various fundamental
aspects of heating, ventilating, and air conditioning.
We have taken special care to make the clinic as uncommercial and
straightforward as possible. Illustrations of Trane products only appear in cases
where they help convey the message contained in the accompanying text.
This particular clinic introduces the concept of the vapor-compression
refrigeration cycle. The absorption refrigeration cycle is the subject of a
separate clinic.
