Chemours and the NHL are working on outreach to community rink owners, operators and mechanical contractors “to offer resources for selection of safe, operationally cost-effective, environmental and financially sustainable alternatives, such as Opteon refrigerants which are non-ozone depleting and have low global warming potential,” Skidd said. The effort covers both retrofits of refrigerants in existing systems as well as equipment replacement in new and existing locations.
Some key players of the global heat exchangers market are Cummins, Alfa Laval, Atlas Copco, Aggreko, SPX Corporation, GEA group, Kirloskar Brothers Ltd., Danfoss, Xylem, Kelvion Holdings, API Heat Transfer, Modine Manufacturing Company, Gunter, HRS Heat Exchangers, Hindustan Dorr-Oliver, and Hisaka Works.

“Whole-house Ventilation System is a set of independent air treatment system, consisting of fresh air ventilator and pipe accessories. Fresh air will be transported through the pipeline to the interior by fresh air ventilator, while the indoor dirty, low oxygen content of air will be emitted to outdoor.”
Tomorrow I’ll post part two of this three part series, explaining standard maintenance and operation of HRVs. On Sunday I’ll post part three, explaining the most common HRV installation defects.
In replacing an R22 system, the CanmetENERGY study found that for a CO2 system the cost would range from $207,000 (€181,585.57) with an unchanged brine loop to $685,000 (€600,900) with a new CO2 loop under the ice.
After building a prototype in the couple’s garage, the startup did a pilot test at a horticultural high school, where energy was being wasted by simultaneous heating of the greenhouse and opening windows to ventilate it. The Terrao system forced cold outside air into stored rainwater that warmed and purified it, then used this air to ventilate the greenhouse. The school’s gas and electricity needs dropped by 45 percent.
As to which refrigerant or system the 31 NHL teams will ultimately employ, “each team or arena owner will be the final decision maker after considering the many factors for their situation,” said Skidd. No NHL arena is known to have used Opteon refrigerants to date.

Gallahan, who started as a journeyman electrician, hopes to head his department one day. “I’ve been here 23 years and I’m still one of the young pups,” he says. “There’s a lot of people that have 30 or 40 years in this company. To me that says a lot.”
Both whole house generator installation companies that I had come out to my property and assess the site for the generator were insistent about keeping the propane tanks relatively close by. They recommend that only 15 to 20 feet should separate the two. The main reason for their recommendations was that trenching for the gas and electric lines is very expensive, and in some cases impossible to do if there are large tree roots in the way. Unless you are willing to pay a high premium for the generator installation, or dont mind taking out a tree or two, then expect to place your whole house generator and propane tanks fairly close to one another.
