2019 AHR Expo

Just returned from attending the Air Conditioning, Heating, and Refrigeration Expo held in Atlanta Georgia.  Some of the biggest names in the HVAC industry, such as Carrier, Trane, and York, were in attendance.  Along with cooling and heating equipment, those manufacturers that make specialty items such as boilers, compressors, piping, controls, motors and refrigerants were also in attendance.  Visitors, as well as vendors, came from all over the world to see new product lines as well as to showcase their products.  The trend, as has been the case for several years now, is to make machines more energy efficient.  Incorporating electronics to measure different parameters such as temperature and pressure, is now routinely done.  Depending on the type of equipment, manufacturers are also offering options on how the equipment is monitored.  Some owners prefer to let their on-site personnel keep up with the operation of their equipment while others are connected by internet to a servicing agency.

No matter how efficient or how well built a machine is, it will eventually fail.  Hopefully, when it does, there won’t be any property damage or personal injury.  But if there is,  the information collected during the Expo on various products will be invaluable in helping to determine the cause of failure and subsequent damage.  More specifically, the literature can be used to help identify a machine by model number, determine the pressure limitations, or establish the power requirements.
