Checking the acidity and/or moisture content of refrigerant oil is one of the methods used to test if a refrigeration system is clean and uncontaminated. But how can you take an oil sample without an oil plug?
While natural refrigerants start to slowly — and cautiously — gain a foothold in North America, their impact is more forceful almost everywhere else. What do other countries have to say about this?
Contractors, take note: The Occupational Safety and Health Administration (OSHA) is currently stepping up its vigilance with new regulations and a new national safety campaign to prevent jobsite falls.
Barack Obama has been re-elected president, Republicans have retained control of the House of Representatives, and Democrats continue to rule the Senate. To naysayers, the election may have seemed like one big waste of energy; however, to energy-efficiency advocates, the election may help eliminate a great deal of energy waste.
Some contractors claim they have been converting oil equipment to natural gas at a record pace. But that doesn’t mean oil furnaces will fade from the marketplace, as there are many areas that have limited access to natural gas. In addition, it can be expensive to convert, and new oil furnaces can provide better comfort and higher efficiencies.
Renewable energy generated by solar, wind, and geothermal technology has garnered a lot of attention lately, but residential biomass central heating systems have not enjoyed the same exposure. What’s holding biomass back?
One sector where CO2 is making the strongest inroads in the United States is in supermarkets as more stores and refrigeration manufacturers embrace its use. Where are two recent examples that make for good reading?
Barring any changes stemming from the pending lawsuit against the Department of Energy (DOE), the new regional efficiency standards for residential furnaces, air conditioners, and heat pumps are scheduled to become effective May 1, 2013. What does that mean for you?
YWCA Toronto recently completed construction of the YWCA Elm Centre, an $80 million, 302-unit affordable and supportive permanent housing complex for women and women-led families. What went into this project?
Recently, there has been a lot of talk about natural refrigerants such as CO2 and hydrocarbons gaining a stronger foothold. Yet much of the talk is related to the possible phasedown of HFC production. And currently, while there may be some talk about a possible phasedown, no actual action seems to be taking place.
