Naturally…Chillventa 2018

The crowded 2018 Chillventa show was a mirror image of what is happening in the HVAC/R market. The HVAC/R sector continues to grow in volume , influenced by the increase in average temperatures, the growing need for personal well-being and the optimisation of production processes and quality of the food chain.  The consequent rising interest among industrial funds towards the...

Are self-contained units ready for natural refrigerants?

The new requirements for reducing CO 2 emissions due to refrigerant and electricity consumption are leading retailers to consider other alternatives to traditional centralised systems. One of the preferred options is the use of plug-in and semi plug-in units , and these are indeed being increasingly used worldwide in different types of supermarkets, especially medium-sized stores. The...

Present and future of natural refrigerants and connectivity

September has been a month especially busy for HVAC/R stakeholders in Spain: Atmosphere Ibérica , focused on the use of natural refrigerants in Spain and Portugal; Tecnofrío , a national conference about refrigeration installations; and Eurovent Summit , the European biennial meeting of Eurovent Association whose slogan was “ ¡Viva La Conectividad! ”. I was lucky to attend both...

EuroShop 2017, the challenge of natural refrigerants

The fiftieth Euroshop held last March in Düsseldorf was the biggest in the event’s history. The organisers have announced record numbers: more than 113,000 visitors, a total of 2,368 companies exhibiting, 18 halls occupied and a net exhibition area of 127,000 m 2.   As regards commercial refrigeration, the sector I know best and have been dealing with for many years now, the...

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...

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...

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...

Natural refrigerants “to avoid a new problem”

Since 1994, every two years, researchers on compression refrigeration circuits around the world meet in a different city to share their work and experiences on natural refrigerants, in honour to Gustav Lorentzen , the Norwegian scientist who rediscovered CO2 as a refrigerant in heating and cooling applications. This rediscovery happened in the late 1980s, crucial days for refrigerants, as...
