AMMONIA LOW-PRESSURE RECEIVER SYSTEMS - This article is based on a presentation at the 2012 IIAR Industrial Refrigeration Conference. The paper received the Andy Ammonia Award for best paper at the conference.

There has been a great deal of discussion in recent years of the merits of “low charge” systems. The incentives to follow this trend are diverse, ranging from the flammability of hydrocarbons or the toxicity of ammonia to the expected higher cost of the new fluids
currently under development and not yet on the market.
The second of this two-part article looks at the practical side of refrigerant phaseout and outlines the various options available, along with some key considerations to help professionals plan for the future.
Star Refrigeration's US subsidiary Azane Incorporated was one of 250 refrigeration end users, HVACR contractors, regulators and industry associations who met in San Francisco to discuss natural refrigerants and the impending R22 phase-out.
The UK’s leading independent industrial cooling and heating contractor, Star Refrigeration, has announced plans to manufacture and supply climate friendly industrial chilling and freezing solutions into the US markets.
We are still thinking about the role of water in refrigeration, so we turn to the old-style absorption refrigerators. I was asked the question recently “why is the hydrogen pressure in a refrigerator so high?” If you are thinking “what hydrogen?”, then what follows may come as a surprise.
May this year marked the 125th anniversary of the birth of Thomas Midgley Jr., a man who transformed our lives in more ways than most of us know, and someone who, for several years now, has been something of a hero of mine.
One hundred and twenty years ago a fire in the cold storage facility at the World’s Fair in Chicago claimed the lives of 16 victims, mainly fire fighters, and injured many more. Recent news reports of multiple
fatalities in China and India have shown that the lessons have still not been learned.
