COLORADO SPRINGS, Colo. — The International Institute of Ammonia Refrigeration (IIAR) held its 40th annual Natural Refrigeration Conference and Expo…

On May 3rd, the North American Sustainable Refrigeration Council (NASRC) in Boise, Idaho will offer a free, full-day overview of natural refrigerants hosted by the Idaho Department of Environmental Quality (DEQ).

Saying goodbye is never easy, whether it’s a relative, friend, or coworker. Last month, I was sad to say goodbye to my dear colleague, Ron Rajecki, who has been the editor of FROSTlines for the last three years. Ron has decided to pursue another “adventure” in the HVAC industry, and he leaves behind some very large shoes to fill.

The Sporlan Division of the Parker Hannifin Corp. certainly made an impact at the 2018 AHR Expo with its ZoomLock Roadshow Experience setting up shop within the company’s booth.

Just like bees return to the hive every day for sunset, Yellow Jacket has habitually returned to the AHR Expo every January for the past 45 years.

The International Institute of Refrigeration (IIR) has launched a quiz on refrigeration and the environment that it says enables participants from all fields and backgrounds to gain rapid insight on key environmental issues.

Focusing on the impact the refrigeration sector can have on the environment from a technical, scientific, and societal point of view, the 10-question quiz is designed to be an informal and amusing way for individuals to familiarize themselves with, and test their knowledge on, this issue.

Known as the “Green Mountain State,” Vermont generates significant amounts of its electricity from renewable energy sources and boasts the smallest carbon footprint in the country. To make sure it stays green, Vermont's Public Utility Commission in the year 2000 created Efficiency Vermont. The innovative program is an energy resource for all in-state rate payers with the end goal of saving energy and putting money back in their pockets.

Motors and drives might be thought of as the elegant workhorses of HVAC and refrigeration systems. They combine old-school toughness and durability with the latest in Internet of Things (IoT) connectivity, and manufacturers are constantly striving to make them more efficient and versatile and easier to monitor and control.

How technicians troubleshoot refrigeration system problems is very personal. Each technician has his or her own style and will use various methods.

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.
