On June 15, 2017, President Trump signed the executive order expanding apprenticeship programs and vocational training. This executive order calls on the Secretary of Labor, Alexander Acosta, “to propose regulations that promote the development of apprenticeship programs by industry and trade groups, nonprofit organizations, unions, and joint labor-management organizations,”

Let’s say I need a new heating system, and I’m calling around (I’m too old to do anything else). I ask you to stop by, take a look at what I need, and tell me why I should choose you over the others.

“I don’t think I’ve ever seen a subject area where so many of the strategic questions are being sorted out in the field,” said Robert Cavey, a partner with Praxis Inc., in kicking off Danfoss’ 30th EnVisioneering Symposium, Refrigerants2Sustainability, which was held Sept. 27 in Orlando, Florida.

According to the U.S. Environmental Protection Agency (EPA), 10,804,918 pounds of ozone-depleting refrigerant was reported as reclaimed by EPA-certified reclaimers in 2016. That total includes 9,409,494 pounds of hydrochlorofluorocarbon (HCFC)-22 or R-22.

Refrigeration systems are made up of major components in series with one another (see Figure 1). As most of us are well aware, the major components are the compressor, discharge line, condenser, liquid line, metering device, evaporator, and suction line.

Many of us remember the pre-internet days, when access to information was limited to books, newspapers, and other written materials, and controlling systems or machinery was generally confined to manually turning a dial or flicking a switch.

When replacing a failed component or accessory for a compressor, it is always best to use the one specified by the manufacturer. There are some components that may have a universal replacement, but you need to be sure the universal component is the right match for the component that needs to be replaced.

Arkema is widely seen as wearing the black hat in the refrigeration industry right now, thanks to the lawsuit in which it and Mexichem Fluor petitioned a U.S. court of appeals to review the EPA’s 2015 rule in which HFCs were targeted under Section 612 of the Clean Air Act.

RSES has released the third edition of its Hydrocarbon Refrigerants study guide and eLearning course. The study guide and eLearning course are designed to assist HVACR professionals in understanding the requirements to safely maintain and service systems that utilize flammable refrigerants currently approved under the Environmental Protection Agency’s Significant New Alternatives Policy (SNAP) Program.

Emerson has created a cold chain organization focused on supporting temperature-sensitive and asset optimization solutions wherever commercial goods are moved, stored, or sold. According to Emerson, the organization will offer customers a total-channel approach to protect foods and other critical cargo at every step along the cold chain — from grower and processor to distributor and retailer.
