Lynn Dison, an applications engineer at RAE Corp., shares the wisdom of six decades
April 4, 2016
Looking back on a refrigeration technology career stretching over six decades, Lynn Dison, an applications engineer with RAE Corp., said that he knew from the very start of it all that he would be at home in the industry for his entire career.
Bob and Tim had just finished a routine service call on a house with a gas furnace for the heating system. They were talking to the housewife when she asked: “Our house is very dry in the winter time, and the humidity must be very low. How can we put a system in this house to keep the whole house at a higher humidity level?”
It is my firm belief that airflow and air distribution is every bit as important in refrigeration design as load calculations. What good is a properly sized system that can’t deliver the air to areas that need it? Poor air distribution and airflow lead to stratification in temperature and humidity as well as poor heat transfer.
For employers, an increase in OSHA fines could be a costly problem, underscoring the importance of a robust and effective workplace safety policy. However, OSHA’s recent enforcement positions are creating confusion over how to implement an effective safety policy.

Located in Zuidas, Europe’s fastest growing business and knowledge district, The Edge in Amsterdam, The Netherlands, is heralded as the world’s most sustainable office building. Officially opened in May 2015, this 40,000-square-meter, multi-tenant, Class A office building was conceived by OVG Real Estate.
In this troubleshooting situation, the equipment is a split system that’s approximately five years old, consisting of a gas furnace to provide heat in the winter, and a condensing unit and “A” coil to provide summer cooling. There are actually three questions to answer in this problem.
Finding R-22 and R-410A alternatives for high-ambient-temperature environments
March 7, 2016
The Oak Ridge National Laboratory (ORNL) High-Ambient-Temperature Evaluation Program for low-global warming potential (GWP) refrigerants aims to develop an understanding of the performance of low-GWP alternative refrigerants to HCFC and HFC refrigerants in mini-split air conditioners under high-ambient-temperature conditions.
Turn on the television, pick up a newspaper, or visit the Internet and you will be inundated with messages about brand products. Tide is a brand. Pepsi is a brand. Nike is a brand. And so are you — or at least you should be.
