First Call Heating and Cooling has a growing Indoor Environment Department that, just a few years ago, was strictly a duct-cleaning business. Today it focuses on all IAQ issues and sees itself as a proactive business pushing the company and its customers towards environmentally conscious heating and cooling options.
Industrial refrigeration, magnetics, and China are apparently on the minds of HVACR engineers. That was reflected in three plenary talks during the most recent combined International Compressor Engineering and International Refrigeration/Air Conditioning conferences hosted by Purdue University.
CO2 as a refrigerant and scroll technology as an important compressor approach were reaffirmed at the most recent combined conferences on refrigeration/air conditioning and compressor engineering at Purdue University. Each topic was addressed in close to 30 papers.
Why do people leave teams and organizations? The No. 1 reason people leave jobs is because they fail to connect with their bosses as leaders and as people. Emotional connections provide the fuel that greatly enhances retention.
Chad Pregracke spent his younger years filled with experiences on the Mississippi. But it was in 1997, at the age of 22, that he kick-started his “cleaning-up-the-river” crusade. Pregracke quickly won the hearts of millions through media coverage of his stubborn insistence that one person really can make a difference.
The daily cost of doing business is becoming a sizeable burden for small and large business owners alike. The Marriot hotel chain is not exempt from these challenges and, with the help of Carrier, it stands to significantly reduce energy costs with the installation of new cooling towers and variable speed drives.
The rigors of cleaning the nation’s major rivers can take its toll on employees and volunteers alike, especially when it’s cold and wet outside. So it’s no surprise that, in compiling the wish list for the new Living Lands & Waters (LL&W) building last year, energy efficiency and comfort were on the list.
Philip Beere, of Green Street Development, a green design-consulting firm in Phoenix, decided in May 2007 to buy and remodel a 1960s-era, ranch-style home. Today, the home - which is Beere’s residence - is the first Leadership in Energy and Environmental Design (LEED)-certified home remodel west of the Mississippi River.
With a new product package, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has put the tools for making the most out of a LEED-intended project at contractors’ fingertips.
Long ago, the industry determined that the combination of copper tubing and aluminum fins provided the most efficient transfer of thermal heat in condenser coils. Manufacturers of residential units are not necessarily on that same page - or that line of thinking - today. Most manufacturers, if not all, are revising, have revised, or continue to revise outdoor coil construction to increase efficiency.
