Johnson Controls Marine Case Study - Absorption Chillers
In the cruise market of today, it is of the utmost importance that we all are committed to low emissions and energy conservancy. As Johnson Controls continuously improve the efficiency of our conventional chillers, and charge them with environmentally friendly, low GWP refrigerants, there still is a huge opportunity left onboard.
Historically most ships have dumped vast amounts of waste heat into the sea – waste heat produced by the propulsion engines in such quantities that shower, swimming pool and laundry heating just cannot use it all. In addition, as more and more ships operate on LNG instead of oil, there is even less use of the waste heat as it isn’t used in preheating the oil.
What better way then, than using proven physics and modern technology in converting this heat into the sought-after cooling, by means of our Absorption chiller?
The waste heat can come in several forms: as steam, as hot water or a mix of the two. The Absorption chiller comes in two sizes, at about 1.0MW or 2.0MW at 32°C sea water depending on conditions.
