The Refrigeration Service Engineers Society’s (RSES’s) 2008 Conference and HVACR Technology Expo had a special sense of occasion. For it came during the year in which the society was marking its 75th anniversary.
An expansion valve has a sensing bulb that constantly monitors the evaporator and varies the flow of refrigerant so that the evaporator is used with maximum efficiency. To provide its advantages to existing systems, a universal valve kit was developed that includes all three types of connections found on older units.
Just before the start of the Summer Olympics in China, the HVACR industry hosted a different kind of competition when the United Association’s (UA’s) 55th annual Instructor Training Program (ITP) was held recently at Washtenaw Community College’s Great Lakes Training Center.

Updated codes and improved standards have helped push for tape improvements.
Studies estimate that more than one-half of all air conditioners in U.S. homes do not perform to their rated efficiencies due to improper installation. Because of this, EPA’s Energy Star™ program decided to utilize the Air Conditioning Contractors of America (ACCA) Quality Installation Specification to start the HVAC Quality Installation (QI) program.
January 2009 will bring about major code changes as they relate to grease duct systems. These changes are far reaching and affect contractors, as well as architects, engineers, and specifiers. These changes, if not addressed, could cause confusion and, in some instances, major redesign, delays, and added costs.
