I just returned from the first-ever National HVACR Residential Sales Managers Forum. Prior to attending seminars and conferences, I always think to myself, “If I can walk away from this event with one good idea, it’s worth the trip.” Little did I know that I would be traveling home with 10, 11, or 12 great ideas - and still counting.
Two persons in the manufacturing sector of industrial refrigeration were among the top honorees at the most recent annual conference and exhibition of the International Institute of Ammonia Refrigeration (IIAR) in Dallas.
The linkage between the refrigerants ammonia and CO2 took another step forward with the announcement at the most recent International Institute of Ammonia Refrigeration (IIAR) Annual Conference and Exhibition in Dallas that “significant progress has been made during the past year on a new CO2 handbook.”
A service technician should not only fix the problem but also, to the best of his ability, ensure the system operates reliably. This means once a technician identifies the system problem, he should try to discover why the failure occurred and what can be done to prevent it from happening again.
The Environmental Protection Agency’s (EPA) GreenChill Advanced Refrigeration Partnership continues to garner more members with the addition of Raley’s stores. According to the EPA, GreenChill partners in the food retail business have refrigerant emissions rates nearly 50 percent lower than the EPA-estimated industry average.
In an effort to address what it calls “hidden costs” and “difficulties in program administration,” the refrigerant reclaim company Hudson Technologies is introducing what it calls a Platinum Reclamation Program.
There are a number of ways that the airflow over an evaporator can become restricted. Anytime the evaporator coil sees reduced airflow across its face, there will be a reduced heat load on the coil. No airflow will cause a lot of the refrigerant in the coil to remain a liquid and not vaporize.
Manufacturers of walk-in coolers and freezers are concerned that a new federal energy-efficiency law that regulates the design of their equipment is going to cause them to lose bids to noncompliant competitors.
After 37 years and dozens of burned-out compressor replacements in the refrigeration service business, Paul Getejanc thought he had seen everything until he peered into the line sets of a recently burned-out 35-ton split-system air conditioning rooftop unit.
Just as much of the world is looking at China as a growing market for most all products, including HVACR systems, it is also a country where researchers are developing their own ways of doing things especially when it comes to chiller technology.
