About Of The Book:
Refrigeration and air conditioning technology 7th edition pdf by WILLIAM C. WHITMAN. Refrigeration & Air Conditioning Technology is designed and written for students in vocational-technical schools and colleges, community colleges, and apprenticeship programs. The content is in a format appropriate for students who are attending classes full-time while preparing for their first job, for students attending classes part-time while preparing for a career change, or for those working in the field who want to increase their knowledge and skills. The emphasis throughout the text is placed on the practical applications of the knowledge and skills technicians need to be productive in the refrigeration and air-conditioning industry.
The book is also written to correspond to the National Skill Standards for HVAC/R
technicians. Previous editions of this text are often carried to the job site by technicians and
used as a reference for service procedures. “Do-it-yourselfers” will find this text valuable for
understanding and maintaining heating and cooling systems.
As general technology has evolved, so has the refrigeration and air-conditioning indus-
try. A greater emphasis is placed on digital electronic controls and system efficiency. At the
time of this writing, every central split cooling system manufactured in the United States
today must have a Seasonal Energy Efficiency Ratio (SEER) rating of at least 13. This energy
requirement was mandated by federal law as of January 23, 2006. SEER is calculated on the
basis of the total amount of cooling (in Btus) the system will provide over the entire season,
divided by the total number watt-hours it will consume. Higher SEER ratings reflect a more
efficient cooling system. Air-conditioning and refrigeration technicians are responsible for
following procedures to protect our environment, particularly with regard to the handling
of refrigerants. Technician certification has become increasingly important in the industry.
Global warming has become a major environmental issue. When HVAC/R systems are
working correctly and efficiently, they will greatly reduce energy consumption and green-
house gases. Organizations like the Green Mechanical Council (GreenMech) are advocates
for the HVAC/R industry and assist the industry in meeting with government, educational,
industry, and labor interests to find solutions to the world’s global-warming problem. Green-
Mech has created a scoring system designed to help engineers, contractors, and consumers
know the “green value” of each mechanical installation. The “green value” encompasses the
system’s energy efficiency, pollution output, and sustainability. Realtors, building inspectors,
builders, and planning and zoning officials will now have some knowledge about and guid-
ance on how buildings and mechanical systems are performing. Green buildings and green
mechanical systems are becoming increasingly popular in today’s world as a way to curb
global warming.
