Although refrigerants have received intense scrutiny over the past decade or so, contractors and technicians know it is only one piece of the HVACR puzzle. Thus, this new refrigerant management software is taking a more comprehensive approach.
Temperature taking requires more and more precise readings given today's complex systems. At the same time, technicians still want thermometers that are easy to use, so time at the jobsite is kept to a minimum.
In order to service today's HVACR systems, technicians need to use more sophisticated procedures and tools. One solution is the Digital Refrigeration System Analyzer (DRSA) from Digi-Cool Industries.
In the supermarket sector, people who make decisions on what kind of mechanical refrigeration systems to use have a variety of options. They are able to spec out every component and control. A new tool can help fine-tune compressor selection.
The recent China Refrigeration Expo (CRE) had so much diversity and complexity, it rivaled the same aspects of its host city. The expo showed the dynamics of the refrigeration and air conditioning industry in the broadest sense, as a global marketplace.
The Kwik-Charger service manifold has a built-in control valve that is said to charge refrigeration systems up to eight times faster than conventional manifolds.
It is truly a global marketplace when it comes to HVACR, and this issue of The News reflects the magazine's commitment to covering industry developments worldwide. The China Refrigeration Expo, held this spring in Shanghai, has gained stature as one of the premier industry events, and News Refrigeration Editor Peter Powell was there.
We install systems in buildings and homes that either add heat or remove it. In this article, we examine what heat is, the various types of heat, the dynamics involved in transferring heat from one substance to another, and the measurement of heat.
In order to differentiate themselves, contractors need to develop "differentiation strategies." Those are the words of Jim Graening, director of commercial programs for Building Services Institute (BSI).
