The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is moving forward with an ambitious project to identify low global warming potential (GWP) refrigerants. What does that mean?
Offered in sizes 6 through 10 tons with belt-drive blowers, the Tranquility Compact Series is available with a vertical cabinet. The series has an extended range refrigerant circuit, capable of ground loop applications, ground water applications, as well as water loop (boiler-tower) applications.
Greenbuild is a good fit for a city with pedi cabs and green spaces, like Toronto; in a Canadian province with many ecologically aimed initiatives, like Ontario. The expo itself, which took place Oct. 4-7, fit snugly within the North and South Halls of the Metro Toronto Convention Centre.
Since the tax credit program became available, all types of geothermal options have been on the minds of the building community. The earth loop, often referred to as the refrigerant loop, may be installed in three different configurations: diagonal, vertical, and horizontal.
While manufacturers continue to look at ways to make HVACR equipment as energy efficient as possible, just as much attention is being paid to finding ways to get that equipment off the electric grid and powered as much as possible by such alternative energy sources as solar, wind, photovoltaic (PV), and geothermal.
For many in the HVAC industry, this is not the first time they have been involved with renewable energy technologies like solar and geothermal systems.
Some years ago it was common for air-cooled condensers to develop leaks, resulting in unpredictable shorter service life. By studying the causes, it’s possible to come up with solutions. It became obvious that vibration was the major culprit, and thermal expansion/contraction creates some specific problems where the hot gas first enters the coil.
The NEWS’ annual Cooling Showcase has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. In this issue, we focus on the commercial side of the air conditioning industry.
