Author Description

Principles of air conditioning serves three main purposes: the content provides a broad background of the principles of science, refrigeration," and air conditioning which must be understood by apprentices, designers, and technicians. This technical information is fundamental -to all types of domestic, commercial, and industrial systems. The planning, designing, construction, operation, and servicing of such systems depend on a complete understanding of this material. The instructional units can be- considered as terminal for those who apply immediately the basic skills developed in the laboratory and shop with this background technical information. The instructional units can be considered as preparatory for those who plan to enter more advanced phases of refrigeration and air-conditioning work, including design and engineering. The text contains seven sections representing major blocks, divisions, or areas of instruction. The material within a unit is organized in a pattern which is
