Hydrocarbons and CO2 are moving to become the European standard for commercial refrigeration equipment, ice makers, and refrigerated display cases. SandenVendo, Epta, Liebherr and AHT Cooling Systems were among those showcasing this accelerating trend at HOST Milano 2015.
Les Atokas Bieler, in collaboration with Carnot Refrigeration, opted for a CO2 transcritical technology to chill cranberries at its new refrigeration warehouse in Quebec, Canada.
A new paradigm in industrial refrigeration is emerging in the United States with ammonia-CO2 systems helping alleviate safety concerns while catering for large-scale refrigeration capacities. Accelerate America investigated the trend in the magazine’s October edition.
The industrial refrigeration sector in North America is changing rapidly as the regulatory environment evolves, driving adoption of natural refrigerants such as ammonia, R744, and even hydrocarbons.
In June 2015 Frialsa opened a new facility. The company had a long history using ammonia since its inception in 1983, but in 2010 decided to work with CO2 as well.
A refrigerated warehouse in the Philippines has reduced its electricity demand and ammonia charge by 85% thanks to an innovative project that preserves perishable food by burning rice husks to provide heat to an ammonia absorption refrigeration unit.
