Container refrigerant technology has depended on refrigerants that, though improved over the past 14 years, still have a negative impact on the ozone layer.
Carrier Corp., a global leader in in high technology heating, air-conditioning and refrigeration solutions – recently announced their newest innovation called NaturaLine, the world’s first natural refrigerant technology for container refrigeration.
This natural refrigerant technology creates a container refrigerant system that incorporates non-ozone depleting carbon dioxide (CO2) in place of conventional synthetic hydrofluorocarbon refrigerants, which have higher global warming potential (GWP). A higher GWP means it contributes to global warming at a higher level. NaturaLine has a GWP of one.
The company says in the event of a leak, the use of CO2 poses no new envinromental risk.
- The system includes a new gas cooler/condenser coil that wraps around the fan.It has enhanced surfaces to maximize heat transfer.
- It takes advantage of a new marine-duty multi-stage compressor.
- It includes new power electronics and an advanced software control system that combine to efficiently optimize fan speeds and compressor capacity to match cooling loads and temperature control.
This new innovative system was announced in Amsterdam on November 30th at Intermodal Europe 2010. Carrier already has several demonstration units in place for around-the-world tests with Hamburg-based Hapag-Lloyd and in 2011, the company plans to extend the program with full field trials.
