This edition of Heatcraft Refrigeration Products LLC’s, Engineering Manual covering Commercial Refrigeration Cooling and Freezing Load Calculations has been prepared in the form of a condensed text and reference book.
The theory and principle of modern refrigeration has been omitted due to the many excellent publications currently available
on these subjects. The purpose of this reference book is to furnish the engineering, selling and servicing organizations with accurate and useful data to simplify load calculations.
No attempt has been made to specify a particular make of equipment. We sincerely hope that our efforts will be a tangible contribution to our rapidly growing industry.
