利用場協同理論分析室內空調之舒適度

Indoor Thermal Comfort by Field Synergy Principle for air-conditioning

摘要


本研究以模擬方式分析探討紊流型進風口位子速度U、V、W、大小、進風溫度、人體溫度與位置、熱負載等參數為模擬之變因,對於空間流場及熱舒適性之差異影響。利用COMSOL軟體模擬流場及溫度場,並以熱舒適度指標探討進風口對其流場影響。模擬結果顯示進氣口之後,對於室內坐位高度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找出進風口的最佳位置。

This research is analyzed by way of field synergy principle to imitate the comfortableness of room. The parameters such as U, V, W, and importing wind position are adjusted to simulate whole domain temperature field and velocity field. Utilize COMSOL Multiphysics software to research flow field and temperature field. 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 air inlet is set. Human becomes comfortable depends on field synergy mean square.
