遊艇駕駛艙空調最佳化之分析

Optimal Comfortness Analysis for Yacht Operation Cabin by Field Synergy Theory

摘要


本研究以分析探討遊艇駕駛艙空間內進風溫度、速度、遊艇空間內之駕駛熱負載、開口形狀等參數為模擬之變因,並利用場協同理論於遊艇空間內進出風口位置最佳化分析並用Comsol軟體分析場協同角的特性。本研究發現,場協同角越低表示速度場與溫度梯度場越平行對駕駛艙速度場與溫度場的冷度越佳,也就是說場協同理論可以用來評估遊艇空間風扇入風位置並提供遊艇設計業者裝設位置的一種指標最佳化設計對於遊艇空間熱舒適性之差異影響。利用COMSOL軟體模擬流場及溫度場,模擬結果顯示,對於遊艇空間舒適性可明顯的改善,其速度場變得較穩定,壓力較均勻。並依模擬結果在利用場協同理論可知流場的溫差與流動速度協同越好也就是角度越小使得風扇的最佳位置。

This research is analyzed by way of field synergy principle to imitate the yacht operation room temperature and velocity field for different input/output fan design. The parameters such as fan position, wind-output window and wind velocity are adjusted to simulate whole domain temperature field and velocity field. Utilize Comsol Multiphysics software to research flow field and temperature field. The index of comfortable degrees is found by field synergy mean square method. The simulation result shows the field synergy angle decreases comfortableness increases, the improvement is very obvious when fan inlet is set. Human in yacht operation room comfortness depends on field synergy mean square value.
