Optimal Design and Energy Saving on Central Air Conditioning System of Ocean Going Ships

Optimal design and energy saving have become the hot spots in air conditioning technology. This paper mainly describes the key design techniques of individual air conditioning system for multi-purpose marine monitoring center and central air conditioning system for "practice teaching ship" of Shanghai Maritime University. The results show that outdoor air pretreatment and second return air system give full play to the superiority of energy saving. The refrigerating capacity will be reduced by 25% without heater and about 30% of energy saving can be obtained comparing with the existing conventional air conditioning system.
