Ten findings on the Australian HVAC/R market

It seems that the characteristic optimism of Australians is also reflected in the country’s HVAC/R market. Whereas HFC refrigerant prices in Europe are rising dramatically, and the lack of a drop-in for R-410A is creating great concern among stakeholders, the general feeling in Australia is that the phase down will go smoothly. This was one of the conclusions I brought back home after spending...

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...

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...

Pros and Cons of Hydrocarbons as Refrigerants

Brief history of CFCs, HCFCs, HFCs, HFOs and natural refrigerants The damage caused by chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) to the ozone layer led to the establishment of the Montreal Protocol on Substances that Deplete the Ozone Layer. Enforced on 26 August 1989 and ratified by 197 countries, it replaced CFCs and HCFCs with other substances that have no...

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...

Italy and Argentina united for more sustainable commercial refrigeration

I knew that this business trip would be different from the others. Going more than 11,000 km away together with representatives of Italian refrigeration companies to explain what is currently happening in Europe definitively seemed promising. “We have 10 refrigeration experts who are like Messi at football”, was how Prof. Cavallini introduced us in Messi’s home capital city. This was very...

Looking for alternative refrigerants to R-410A @ Heat Pump Summit in Nuremberg

Late 2017. “What is the replacement refrigerant for R-410A” is the question that perhaps more than any other is being asked in the HVAC industry. This is a consequence of other factors, such as: how much will R410A cost in the next semester ? Will it continue to be so difficult to source as has been the case for the last few months? Personally, I tried to find a response by participating...

ATMOsphere Ibérica: how to cool when it’s really hot?

With an outdoor temperature of 26°C on 24 October, it could be said that the weather in Madrid was in line with the main focus of the first ATMOsphere Ibérica event: the challenges of natural refrigerants in warm climates. “Climatic conditions in Spain, Portugal and Latin American make the transition to natural refrigerants, in particular CO 2 , more difficult”, stated Alvaro de Oña, the...

How will commercial refrigeration develop in the future?

Undoubtedly, the expansion of commercial refrigeration is likely to continue due to the growing importance of food preservation . The food chain from “ field to fork ” must be able to guarantee food quality and safety , and above all for fresh products with a short shelf-life this can only be ensured by low temperature transport and storage, so as to prevent bacterial growth: indeed, ...
