Being aware and paying attention to what’s around you, where you are, and what’s happening can be really important. Sometimes for whatever reason, we miss something that we may be looking right at, hearing, smelling, etc. I’m sure that we all have some lack of awareness and/or have not been paying attention at various times. Lack of awareness and attention can be caused by several factors such as exhaustion, sickness, demands on your time, stress, boredom, hunger, etc.
Read MoreAs in other regions of the world, the past months have been heavily influenced by the global pandemic. But despite or perhaps because of the pressures introduced by the pandemic, business in European industrial refrigeration has increased quite a lot, and as such, the difficulty has been and still is to maintain the human resources to continue working even with pandemic-related challenges.
Read MoreOver the last 15 years the market for high-temperature ammonia heat pumps has been growing in Europe and now it is also taking off in North America. That period in Europe has yielded many lessons as higher pressure and temperature present new challenges in refrigerant design. This paper explains where heat pump installation differs from refrigeration installation through three case studies of installations in Europe.

Many times we don’t think about how we learn, which is something we are or should be doing most of our lives. This fact was brought home to me this past winter as I became involved as an instructor in a winter sport I like. As I was learning to be an instructor and understanding how people might learn I could see a correlation between what and how someone is teaching and how people learn.

What happened to the IIAR Bulletins? Short Answer: The IIAR Bulletins were all “Superseded!” Let’s discuss the history of the onset of IIAR Bulletins and how their material was eventually distributed and captured to become superseded.
Read MoreSafe oil draining is a subject that is well documented in IIAR publications, and workshops dealing with proper oil draining are always well-attended. Removing oil from an ammonia refrigeration system is routine maintenance that nearly every ammonia refrigeration system operator will encounter sooner or later. One major advantage of ammonia systems is that oils are not normally soluble with ammonia and will therefore collect at the lowest spot in the system. However, accumulation of oil is gradual, and the location for accumulation must be suitable, i.e., calm enough, such that oil gets a chance to settle.
Read MoreThe IIAR Compliance Committee has updated the Guideline for Developing an Energy Control Plan for Manual Hand Valves and released a second edition. “After a guideline has been out and used in the industry, members and users will ask questions and provide input for consideration to make the guideline even clearer to use or capture additional information that enhances its value as a practice,” said Tony Lundell, senior director of standards and safety for IIAR. “An addendum typically will have minimal changes which could include simple edits, and/or provide statements that can add value to the guideline.”
Read MoreAdoption of natural technologies in new and existing retail space is increasing as companies work to increase sustainability while meeting consumer, employer and shareholder expectations. “Many retailers, especially national chains, are prepared to make very large investments to significantly reduce their carbon footprint by converting to naturals in existing stores,” said Danielle Wright, executive director of the North American Sustainable Refrigeration Council.

Participating in IIAR conferences, webinars, committees, and sub-committees has certainly increased my knowledge and my access to information. I have listened to and worked with very knowledgeable people from many backgrounds. Even after being involved in the ammonia refrigeration industry, and specifically IIAR for many decades, I am still learning. This reminds me of a famous statement I read in a book by Donald Rumsfeld, who served as George W. Bush’s secretary of defense.

Joe Biden began his presidency on January 20th by signing a series of Executive Orders impacting a wide range of policy issues. In just the first 10 days of his Administration, Biden took 42 individual executive actions, many of which reversed policies instituted by former President Trump. Regulatory review and climate change are among the major actions that will have an impact on the natural refrigerants industry.
Read MorePressure relief design documentation is often the most misunderstood portion of the Process Safety Information required under 29 CFR 1910.119(d) (3)(i)(D) and 40 CFR Part 68.65(d)(1) (iv). The two regulations state that the relief system design AND design basis shall be included in the process safety information pertaining to the equipment in the process. The word “design” is fairly straightforward. The Cambridge Dictionary defines the word design, when used as a noun, as “a drawing or set of drawings showing how a … product is to be made and how it will work and look” or “the way in which something is planned and made.” Sounds simple, right? We need to have the technical specifications and physical arrangement of the relief design documented. Easily done.

Buckling our seatbelts, filling our own gas tanks, sending an email, and burning propane or natural gas in our homes for heating was once unthinkable. These technologies replaced dad’s arm across your chest during a fast stop, the serviceman pumping gas and checking your oil level, typewriters and the mail service, and coal or wood-burning stoves. There are times I wish to go back. Like when it’s pouring rain and I am nearly out of gas, or when my PC fails, and I feel helpless. Boy wouldn’t that gas station attendant or typewriter be great now.

Conference time is here again and although it’s hard to think we’ll spend one more year meeting online rather than in person, there’s a lot to look forward to. For the executive committee and your staff at headquarters, that means everyone is working hard to make sure our recent initiatives – from the renewed focus on IIAR member benefits to the many new projects our committees have started – will put us in the best possible position as we look forward to the eventual end of this pandemic.
Read MoreIn the first article of this series, some of the factors that affect the relief capacity of a relief system that are often overlooked were highlighted to raise awareness of what is needed to properly document the safety relief design. In this article, we will discuss some of the pitfalls associated with internally relieving relief valves. It has long been held that the best way to relieve overpressure in an ammonia refrigeration system is to have the safety relief valves (SRVs) relieve into another part of the system, often simply on the opposite side of the downstream isolation valve. While this can be a viable option, it is often fraught with pitfalls.

In my February 2019 article, I examined the need for sprinkler systems in machinery rooms in the USA and their prohibition in Europe. Afterward, I was contacted by Jeff Shapiro who indicated that Anders Lindborg, an honorary life member of IIAR and expert on ammonia releases, had changed his mind just before he passed away and was no longer arguing against sprinkler systems in machinery rooms. Jeff also provided his article from 2011 that laid out the different perspectives of experts from each side. It is evident that this has been a long-running discussion and has caused some confusion within the industry.

Estimating the amount of ammonia lost due to an accidental release can be a complex process and when they do occur, end-users want to avoid underpredicting or over-predicting release quantities. Presently, there is not a single reference guideline that provides details for calculating ammonia quantities released as a consequence of incidents.
Read MoreAfter years of work, it is more than likely that all code bodies will now refer to IIAR for ammonia refrigeration requirements by 2024. IIAR has made significant progress towards this goal over the past 20 years, but there was one outlier—the International Fire Code. However, the IFC’s technical committee has approved a proposal for the 2024 edition of its model code, deferring all matters related to ammonia refrigeration to IIAR.
Read MoreRemoval of non-condensables and excess water is essential when starting up new refrigeration systems or large retrofits. Non-condensables contribute to higher than necessary head pressure, and excessive water in a system can cause inefficiency and operational problems. In all refrigeration systems, non-condensables and water vapor are removed from systems by vacuum pumps prior to charging with refrigerant. Removing liquid water (dehydration), can be done by “pulling” a deep vacuum – enough to boil the standing water and remove the vapor through the vacuum pump.

A revocable living trust can be a useful and practical estate planning tool for certain individuals, but not for everyone. This type of trust is most commonly used to avoid probate because, unlike property that passes by will, trust assets are distributed directly to heirs. This type of trust is also used as a way to maintain management of one’s financial affairs during a period of incapacity because someone else can immediately take charge when needed. A revocable living trust does not minimize income, gift, or estate taxes, nor does it shelter trust assets from creditors in most cases.
