Amazing smart technology: are we ready for the new Nerds?

Last night I was watching a TV game show: there was a 23-year-old contestant who didn’t know that the acronym CPU stood for the central processing unit of a personal computer. This seemed strange to me, and so I started wondering why. When I was that age, a little less than 20 years ago, a computer was an object of desire, whose hardware specifications, such as the processor, RAM and hard...

DCW London - Continuous evolution of Data Centres: IoT, edge and “fog computing”

Once again this year Carel took part in “Data Centre World” (DCW) London, one of the most important events in this sector worldwide, attracting the main operators in the field of ICT (Information and Communication Technology) infrastructure. The trade show is held in conjunction with other events (Cloud Expo, Cloud Security Expo, Big Data World and Smart IoT) and thus represents a very...

MCE 2018: innovation frozen by lack of HFCs?

Mostra Convegno Expocomfort (MCE), held this year in Milan from 13 to 16 March, has always been an exhibition showcasing innovation in the HVAC/R business. Indeed, I have always appreciated the emphasis placed by exhibitors in presenting their new ideas and solutions in Milan, much more than at other important events that are held periodically in Europe, Asia and America. The 2018 event saw ...

Making sense of the uncertainty that the future holds for refrigerant regulations in the USA

To say that the next few years will be a smooth ride for the HVAC/R industry in the United States of America easily transitioning to the next generation of low GWP refrigerants, would be the understatement of the year. There is a network of potential pathways to achieve HFC (hydrofluorocarbon) phasedown in the USA; each one is a mixed bag of educated guesses, misinformed opinions and litigated...

Why improve when things are going well?

We all know the story of Nokia, which in the 1990s was the undisputed leader in the sale of mobile phones. They made the best phones, with a quality of reception that even now few others match. But then someone in the USA invented the iPhone and the company went into a downward spiral that it has still not recovered from. In the past, makers of audio tapes found themselves displaced by the...

New efficiency limits for condensing units!

Less than 4 months remain to prepare for more stringent limits on European condensing units! In detail, Ecodesign requires an increase in efficiency of between 6-14 %, depending on the categories, compared to the 2016 tiers. This comes at a crucial moment for HFC phase-down and with some uncertainty among condensing unit manufacturers regarding the alternative refrigerants to be used, which...

The best trade-off for a low carbon footprint In commercial refrigeration units

Undoubtedly the best results in terms of reducing carbon footprint and environmental impact are achieved using a variable-speed compressor working with a natural refrigerant, i.e. R-290 (Propane), with intrinsically high thermodynamic efficiency. In our point of view, a compressor for a plug-in commercial refrigeration unit (i.e.: bottle coolers, chest freezers, display cases) should be: ...

From 150 to 500 g of propane: higher charge, same risk?

2018 may be the year when the charge limit of 150 g for flammable refrigerants in commercial refrigerators will be increased to 500. This may be a very important step towards the use of natural refrigerants , while on the other hand it entails a huge responsibility in terms of safety. Indeed, the working group that is defining the additional requirements has the scope of ensuring that the...

AHR EXPO Chicago: improving the user experience

From 22 to 24 January, Chicago hosted AHR Expo, a great opportunity to take stock of HVAC/R market trends: a goal that was fully met over three very intense days of meetings and discussions, with the possibility to explore topics of current interest from both a technical viewpoint (the future of refrigerants, the continuous search for better energy efficiency...) and as regards the ...

2018 ASHRAE Winter Conference in Chicago

  Humidification: renewed interest! Refrigerants: feeling the “natural” pressure?   The ASHRAE Winter Conference was held on 20-24 January 2018, during some mild winter weather (incredibly for Chicago, just around freezing!). Like all ASHRAE Conferences, the event was attended by several thousand people, who asked questions, learned and profitably networked during the...
