IIARThe Official Magazine of the All-Natural Refrigeration Industry
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.
Read MoreFor 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.
Read MoreInternational 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.

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.

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.

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.
Read MoreThis 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).

Read MoreIn the wake of the pending global phase-down of HFCs due to their contribution to global warming, users and owners of refrigeration systems are faced with decisions that at times appear difficult. These decisions relate to whether or not users continue to employ HFC-based refrigeration systems, switch to low GWP synthetic refrigerants or consider future-proof natural refrigerants such as NH3 , CO2 , hydrocarbons, water, or air in their new and/or expanded systems. In this decision-making process, one very important factor is often either overlooked or underestimated. This factor is energy performance—particularly the energy performance of low charge NH3 systems.
