EDITORIAL ACKNOWLEDGMENT FOR 16 years the Heating, Ventilating, Air Conditioning Guide has been published by the American Society of Heating and Ventilating Engineers and it retains its leadership as the authoritative reference volume of the profession and its allied industries. Its users are legion and they have adopted The Guide as their standard reference source because they recognize that the data are unbiased, up-to-date and readily usable. TJiis has been made possible because of the willingness of hundreds of technical experts to contribute freely from their knowledge and practical experience for the advancement of the profession. To the following individuals the Guide Publication Committee is profoundly grateful for their assistance in the production of the 1938 edition, and also to those former contributors who have previously prepared a firm foundation for the addition of new material.
