Register Now, the IIAR Heavy Equipment Show is Just Around the Corner!

The end of the year is coming to a close quickly, and that means your IIAR staff at headquarters is busy preparing for the next annual conference, in March at the Rosen Shingle Creek Hotel and Resort in Orlando, Florida. I’m excited to announce many additions to this Heavy Equipment Show that are new in 2020 and highlight the many advantages of IIAR membership, so consider this your official invitation to another can’t-miss IIAR conference!

Energy and Sustainability

I often think about the myster of human thought. How something unseen and metaphysical can affect and alter things that are seen and physical. The old saying is certainly true, that “Ideas have consequences”. As an engineer I was taught that entropy (disorder) unavoidably increases in the universe according to the second law of thermodynamics.

IIAR Moves Forward on CO2 Standard

The use of carbon dioxide as a refrigerant has continued to increase, and the IIAR is moving closer to finalizing a new CO2 standard, which will address several critical aspects of CO2 refrigeration, such as installation, startup, inspection, testing and maintenance.

Advancements in Refrigeration Equipment Require Advanced Lubricants

Any machinery with moving parts requires a lubricant, and the lubricant landscape within the refrigeration industry has gotten more complicated over the past 25 years as new types of equipment have entered the marketplace.

Foundation Sees Fundraising Success

The Ammonia Refrigeration Foundation is in the midst of its annual fundraising drive, and this year is already looking promising, said Joe Mandato, chairman of the ARF board of trustees.

Clean Evaporator Coils Reduce Energy Expenditure, Lower Costs

Numerous factors can contribute to decreases in a refrigeration system’s energy efficiency, not the least of which is its cleanliness. Much of the time, when facility operators see a facility’s efficiency drop, they believe that indicates they must replace the systems with larger units, when in fact, they often simply need to clean the systems they’re currently using - particularly the evaporators.

ASME Low Temperature Requirements for Impact Testing

For those of us that didn’t major in metallurgy, steel was always a pretty simple material. It was pretty springy and flexible stuff. Just about any shape was possible. Steel could be loaded up to a point and it would bend, but when unloaded it would spring back to its original shape.

From the Montreal Protocol to the Paris Agreement: How Refrigerants Have Felt the Chill of Global Environmental Regulations

International refrigerant related environmental regulation began in a laboratory at the University of California, Irvine, in 1973 when a postdoctoral fellow, Mario J. Molina, under the supervision of F. Sherwood Rowland, made a groundbreaking and controversial hypothesis that chlorofluorocarbons (CFCs) could destroy ozone (O3) in the Earth’s stratosphere.

International Update: A Focus on Education in Latin America

In Chile, the International Committee of the IIAR has been working with the University of Santiago’s department of mechanical engineering along with the Chilean Chamber of Refrigeration and Air Conditioning (CChRyC) to develop a diploma track specifically to prepare refrigeration engineers to work with ammonia systems. The first class – 14 engineers in total – recently graduated.

Understanding Bond Yields and the Yield Curve

When it comes to investing in bonds, one of the first factors to consider is yield. But what exactly is “yield?” The answer depends on how the term is being used. In the broadest sense, an investment’s yield is the return you get on the money you’ve invested. However, there are many different ways to calculate yield. Comparing yields can be a good way to evaluate bond investments, as long as you know what yields you’re comparing and why.

Pre-emergency preparedness

Are you prepared? I think most of us think we are LESSON prepared, at least to deal with whatever we expect to happen. The trouble is that often what we come up against is not something we expected – therefore we are not prepared to deal with it. For ammonia refrigeration whether a system has 400 lbs. or 40,000 lbs. (or more) we should do pre-emergency planning and training.

Regulatory Reforms Advance in Canada and U.S.

Regulations are a major consideration for the industrial refrigeration industry in the United States, Canada and many other countries. IIAR has long worked to improve the regulatory climate in the U.S. and is now working to broaden its influence across the globe. In some cases, this takes the form of promoting IIAR standards in countries that do not have well established regulatory schemes. In other cases, IIAR is working to advance regulatory reforms to reduce regulatory burdens while maintaining safety.

Developing and Implementing Effective Ammonia Refrigeration System Operating Procedures

This paper provides guidance on developing and implementing operating procedures for ammonia refrigeration systems. The regulatory information is based on the U.S. Occupational Safety and Health Administration (OSHA) Process Safety Management (29CFR1910.119) standard (1992), the Environmental Protection Agency (EPA) Chemical Accident Prevention Provisions’ (40 CFR part 68) Risk Management PlanRule(1996), and the IIAR standards for Developing Operating Procedures for Closed-Circuit Ammonia Refrigeration Systems (ANSI/IIAR7-2013).
