Becoming a successful HVAC salesperson can be an intricate juggling act. Instead of juggling dozens of balls to get a sale, there are really only five items that you need to master and put into place to become a sales master
With more manufacturers building R-410A systems, the need for training and certification continues to grow. To assist educators and trainers in teaching R-410A safety, installation, and service, the ESCO Institute has released two new teaching aides.
Pumps are responsible for a significant part of the world’s electrical energy consumption, but their impact can be by using variable-speed pump control, especially in hydronic systems, according to speakers at the annual meeting of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
Planning is already underway for the every-other-year conferences at Purdue University dealing with compressor engineering and refrigeration/air conditioning. The International Compressor Engineering Conference and the International Refrigeration and Air Conditioning Conference take place concurrently July 14-17, 2008, on the Purdue campus.
The compressor’s discharge temperature can tell the service technician what is going on inside a refrigeration or air conditioning system. The compressor’s discharge temperature is a reflection of the hottest part of a refrigeration system, and there are limits as to how hot a discharge temperature should be. This article will explore discharge temperatures and their limits.
A move toward sustainability was highlighted at the annual meeting of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Approximately 1,600 members attended the meeting, which supported the society’s mission of advancing HVACR science to serve humanity and promote a sustainable world.
Servicing and maintaining refrigeration equipment often requires techs to measure the pressures and temperatures, and calculate the condition of the refrigerant at several different locations throughout a system. One aspect that is sometimes overlooked is the superheat value of the refrigerant at the inlet of the compressor. This is commonly referred to as the system’s total superheat.
Some 25 experts from the HVACR industry addressed growing concerns about the U.S. energy situation at the fifth Danfoss EnVisioneeringSM Symposium, “Making Dollars and Sense of Energy Efficiency: A Focus on Conservation.”
Call it a church revival or preaching to the choir, but when
Joel Gilbert of Apogee Interactive gives the keynote talk at the upcoming Food
Marketing Institute Energy & Technical Services Conference, he will be
telling those who think they have done it all in terms of energy savings that
there are still ways to do better.
In order to understand the future of the school market, you have to look at and understand the past while staying on top of new technologies and codes.
