Synopses & Reviews
The only text that takes basic math concepts and applies them specifically to HVAC! This unique text covers the entire range of mathematical problems and subjects encountered by HVAC technicians in real-world situations. With practice problems, a review unit, and three review tests, students can easily assimilate the material presented and visualize its use in the field. A glossary defines terms specific to HVAC, while conversion charts present critical field information at a glance. This book works well as a math text all by itself, or in conjunction with a general math text. An instructor's guide includes two achievement review tests with answer keys, as well as answer keys to problems in the book.
Synopsis
An excellent refresher or reference source, this book provides HVAC technicians with a simple presentation of basic mathematical concepts--and how they apply in the field. Numerous figures help technicians visualize the practice problems presented in the book, all of which relate directly to HVAC. Detailed mathematical charts--for conversion equivalents, formulas, trig functions, and heat transfer multipliers--present critical field information at a glance, while a unit on bill writing helps technicians deal with the public.
Synopsis
From basic arithmetic to using formulas, this fully updated edition applies essential practical math skills directly to the field of heating and cooling technology. All math concepts use terminology specific to the HVAC-R trade to help technicians prepare for problems they will encounter on the job. The entire range of mathematics problems used in the field are covered - from whole numbers, fractions, ratio and proportion, to percentages, measures, formulas, and trigonometry. Useful practice opportunities in the book also help readers learn to write up estimates and bills.
