摘要：
The aim of this study was to explore the operation characteristics of marine variable air volume (VAV) air conditioning system during navigation in each representative day and the whole voyage. In the multifunctional cabins of an ocean-going ship, numerical simulation was carried out to investigate diversified performance parameters of this system. At the same time, the mathematical models of main equipment and VAV system simulation model, which were coupled with an hourly dynamic load calculation model, were developed to analyse the energy consumption in a representative day and the whole voyage. The relative deviations of supply air volumes of all VAV terminals were within 11%, and the supply air temperature and room temperature fluctuated within +/- 0.2 K and +/- 0.3 K, respectively. Besides, the energy consumption of this system was lower than that of constant air volume air conditioning system, with the energy-saving rate of 26.82% by simulating calculation.
