Carrier Transicold, the world's leader in high technology transport refrigeration and shipping temperature control solutions and a part of UTC Climate, Controls & Security Systems, a unit of United Technologies Corp, announced two significant innovations using the natural refrigerant carbon dioxide (CO2), revolutionizing refrigeration technology for temperature-controlled transport applications.
At the Intermodal Europe Show in Hamburg, Germany, Carrier Transicold revealed the NaturaLINE™ container refrigeration system, the world's first to use natural refrigerant CO2 for marine applications. A day earlier, at the Solutrans Fair in Lyon, France, the company displayed a CO2 concept trailer refrigeration model for road applications.
"While presently there are no bans on the use of traditional refrigerant chemicals in transport refrigeration applications, Carrier Transicold is committed to offering a more environmental alternative with natural refrigerant solutions to our customers, even before potential regulations take effect," said David Appel, president, Carrier Transicold. "By using CO2 as a natural refrigerant, the NaturaLINE design improves upon our PrimeLINE™ unit's ability to reduce carbon dioxide emissions 28 per cent compared to previous units."
Carrier uses CO2 recycled from the atmosphere for refrigerant cooling, so it adds no new environmental risk. Considering that the average energy consumption of a container machine using standard refrigeration can reach more than 10,000 kWh per year, CO2 emissions total more than 10 million tonnes for the installed base in excess of 1 million refrigerated containers.
Though this is considered a relatively small number when compared to CO2 emissions produced by the container ships themselves, and even smaller when compared to total emissions produced by global industry, the result still requires attention and action to reduce emissions where possible.
The NaturaLINE product design introduction, which includes a patented, multi-stage compressor and several other innovations equal to the energy efficiency of the industry's most energy efficient unit also produced by Carrier, comes exactly one year after the company announced it had developed the technology and successfully completed three demonstration voyages with one of the leading global container shipping lines, Hapag-Lloyd.
At the Solutrans Fair, Carrier Transicold's CO2 concept trailer refrigeration unit compared very favourably to the conventional units it will eventually replace. The Global Warming Potential (GWP) of CO2 is lower than other alternate natural refrigerants, such as propane and ammonia, so even in the event of a leak, the use of CO2 adds no new environmental risk, the company wrote.
