Debunking the myths about humidity

Often the word humidity is associated with commonplaces that have negative connotations. In reality, many ideas we have about humidity are wrong, based on just superficial knowledge of what it really is.  The aim of this article is to list some of the most common "false myths" regarding humidity, to understand how it is more useful (and often essential) than is often thought...

Walk-in coolers and freezers in USA: the deadline is getting nearer!

Whereas many media-friendly political decisions have been made during the first 100 days of the new US administration, people working in HVAC/R sector are wondering whether the refrigerant and energy efficiency rules previously published will be kept. Looking at the DOE (Department of Energy) website, it can be seen that at the end of December 2016 a large number of final rules were...

Relative humidity: our first ally in the invisible war against bacteria

Every day, an invisible war is waged in hospitals and healthcare facilities whose outcome is crucial for people’s lives. On one side, the vast number of bacteria and viruses that are omnipresent in such places, being brought inside by sick patients, visitors and even the medical personnel, and that reproduce very quickly and are often able to resist the most common antibiotic...

Which refrigerants are allowed worldwide on stand-alone units?

Undoubtedly, the phasing out of HFC refrigerants has already started. The prices of high GWP refrigerants are gradually rising while availability is decreasing. For instance, Honeywell announced a few days ago that they are going to stop selling R-404A and R-507 in Europe . At the same time, Chemours has recently announced consecutive monthly price rises of 25% and 30% for high GWP...

New regulation on hospital humidification: cheap and clean, is it possible?

Air conditioning systems, including humidification, account for a major part of hospital daily running costs. Achieving energy and cost savings on these systems can bring considerable relief to hospital budgets, which often have to respond to public spending cuts and challenging energy consumption targets. The important question is therefore: can the need for humidification in...

EuroShop 2017, the challenge of natural refrigerants

The fiftieth Euroshop held last March in Düsseldorf was the biggest in the event’s history.

Humidity control in museums and libraries

The materials used to make the conserved artworks are the same as those already examined: canvas, wood, paper, parchment; nonetheless, the conservation of these requires limits that are much stricter than those relating to the material alone. An alteration in the dimensions of the canvas of a painting may cause the paint to peel; the same effect with wood may produce cracks in the...

Vegas! So dry, so nice. Or is it?

Las Vegas, Nevada, the city of fun, gambling, good food and many, many wonderful shops inside glittering hotels! I spent there a few days there for the 2017 ASHRAE Winter Conference at the end of January, and indeed I enjoyed it. The seminars and conferences were very helpful and instructive. The weather was great, with the sun shining, blue skies and temperatures around 18 °C / 64 °F;...

What was the HVAC/R sector talking about in Madrid?

Two weeks ago I was lucky to attend the Climatización y Refrigeración show in Madrid. It was exciting to once again see how our HVAC/R sector is not only thriving, but extremely active in the development of new solutions that the market is demanding. As predicted, this time the trends are mostly being driven by standards and regulations, specifically F-gas and Ecodesign in...
