As we finish our “non-summer,” the impact was not as severe on us as it was on many of our competitors because of the strong emphasis we have on maintenance agreements. So once again I am going to make a strong pitch to encourage you to have a very extensive maintenance agreement program.
Maintenance helps mechanical systems live longer, but how about its effects on system efficiency and sustainability? A seminar at the 2008 Annual Meeting of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) offered contractors a way to justify maintenance with efficiency gains.
The Leadership in Energy and Environmental Design (LEED) Green Building Rating Program that has been growing in the United States has now reached the Canadian supermarket industry. Canada’s first LEED-certified supermarket is a showcase of green, sustainable HVACR technologies.
Sustainability and its cousin, “going green,” have stepped up their presence in the refrigeration sector, after gaining a high-profile position in a/c. The most recent Food Marketing Institute Show found dozens upon dozens of the close to 800 exhibitors promoting themselves as sustainable and green in some way.

This is the first in a series of three articles covering the scroll compressor. This first article covers the history of the scroll compressor along with the scroll compressor operation.
One type of starting relay used on fractional horsepower compressors is the positive temperature coefficient (PTC) relay. It performs the same function as a current relay or potential relay but in a much different manner.
The topic “The Owner Nexus: Will Building Owners Transform Energy Efficiency in the Built Environment?” drew city leaders, building owners, engineers, builders, managers, and other stakeholders to Denver to discuss the growing concerns over energy and climate change in the building industry.
Since launching last November, the GreenChill Advanced Refrigeration Partnership has nearly tripled its membership and prevented emissions of 2.5 million metric tons of carbon dioxide equivalent, according to a report from the U.S Environmental Protection Agency (EPA).
Historically, builders haven’t offered a wide variety of HVAC or IAQ options, and home buyers who have wanted something different may have had trouble getting it. That scenario is starting to change, however, as more home buyers are asking builders for upgraded mechanical systems and IAQ options.
