Many service technicians believe that frost on a suction line or on the compressor’s head itself indicates there is liquid refrigerant coming back to the compressor. Is this really true?
When it comes to industrial and commercial refrigeration, high on the research radar screen are low GWP alternative refrigerants for everything from small bottle coolers and freezers to entire supermarket systems.
When the EPA’s Greenchill’s Keilly Witman spoke at the Food Marketing Institute Expo last spring she said so-called natural refrigerants would dominate the conversation and begin to appear in supermarkets in North America. Was she right?
HVACR contractors who replace TXV valves during servicing are always seeking ways to carry the variety of valves they need in their vans or trucks. One new approach comes from Danfoss with its Maximizer and Minimizer kits, which package multiple TXV combinations in one place.

ICOR International has developed Tech Tools, a mobile application that will supply refrigerant knowledge and resources for anyone that carries an iPhone®, iPad®, or iPod touch®.
As this is being written temperatures are near 100°F here on the Illinois/Wisconsin border and a drought is in full force. The hue and cry is, “See, see, global warming! Told you it was real!” But folks from Europe were telling me that the Old World was experiencing one the coolest and wettest summers on record.
Demand for HVACR products looks to be rosy over the next several years, as HVAC and commercial refrigeration equipment demand is expected to go up several percentage points through 2016, according to the studies World HVAC Equipment and Commercial Refrigeration Equipment from The Freedonia Group.
