Refrigeration just took another step into the green frontier. In October of last year, Kysor/Warren installed an HFC-free refrigeration system in a Fresh & Easy market in Rosemead, Calif. The system, one of only four in the country, uses CO₂ as the refrigerant. Due to their innovation, the Rosemead Fresh & Easy is expected to reduce its impact on the ozone layer by 70% less than the industry standards.
I think this could be really huge news for our industry.
Using CO₂ as a refrigerant makes a lot of sense – though I’m no refrigeration expert. Consider this though: carbon dioxide is assigned a Global Warming Potential (GWP) factor of 1. The current industry-standard refrigerant R134a carries a factor of 1300. This means the negative impact of R134a on the greenhouse effect is 1300 times higher than that of carbon dioxide! If CO₂ does happen to leak from the system, it has negligible negative effects on the environment.
