Green just got cool<br />
Is there an industry in the world today not concerned<br />
about the environment? If it exists, it is not the cruise<br />
industry. <strong>Cruise</strong> customers are aware of environmental<br />
issues and increasingly expect cruise lines to follow greener<br />
practices. One way the industry can improve its standing is<br />
through the application of environmentally friendly<br />
refrigeration technologies.<br />
GEA Grenco is a market leader in implementing<br />
environmentally friendly refrigeration systems for the marine<br />
industry. Headquartered in Den Bosch, The Netherlands, it has<br />
a second office in Miami, US.<br />
There are two factors related to environmental refrigeration<br />
systems: the loss of refrigerant into the atmosphere and the<br />
energy efficiency of the refrigerant.<br />
Some of the most commonly used synthetic refrigerants have<br />
ozone depletion potential (ODP). There has been pressure for<br />
years to ban so-called HCFC refrigerants.<br />
The Montreal Protocol, which came into force in Europe in<br />
January 2010, practically brought an end to the use of HCFC<br />
refrigerants with a total production ban of the synthetic<br />
refrigerant known as R22, and the topping up with virgin R22.<br />
Technically, R22 is a good refrigerant and widely used.<br />
However, when it leaks into the atmosphere, it damages the<br />
ozone layer. The next generation of synthetic refrigerants has no<br />
ODP. However, the total environmental global warming potential<br />

GEA Grenco’s environmentally friendly refrigeration systems use natural refrigerants that allow<br />
cruise lines to drastically cut some of the emissions that contribute to global warming, helping<br />
them improve their green credentials.<br />

Efficient refrigeration can help ships improve<br />
their environmental performance.<br />
<strong>Cruise</strong> line’s are increasingly improving their green practices.<br />
(TEWI) has become an issue. TEWI describes the combined<br />
effect of refrigerant leakage and energy consumption on global<br />
warming. The impact is comparable to the emission of 1kg of<br />
CO 2 . The leakage of 10kg of the refrigerant R404 has the same<br />
impact on global warming as driving a medium-sized car<br />
approximately 90,000km. In comparison to natural refrigerants,<br />
the use of synthetic refrigerants increases fuel consumption for<br />
marine refrigeration systems.<br />
The refrigeration industry has re-introduced natural<br />
refrigerants as they have no ODP and practically no impact on<br />
global warming. It is expected that the next generation of larger<br />
cruise ships will apply this technology.<br />
GEA Grenco also uses these refrigerants for other marine<br />
applications and sees possibilities of using 100% natural<br />
refrigerants. By implementing this technology, the cruise<br />
industry will take another step towards offering environmental<br />
friendly holidays for its customers. �<br />
