摘要

本研究以國際標準ISO7730為基礎並用數值模擬軟體MATLAB建立了舒適性指標（PMV）與不滿意百分比（PPD）模式。此舒適性指標需輸入7種參數來做舒適性評估，包含了人的代謝率、作功、穿著服飾的熱阻、環境空氣溫度、環境輻射溫度、相對濕度和空氣相對風速。為驗證此舒適性模式運用於台灣的合理性與適用性，此研究根據台灣中央氣象局提供的氣象資料來模擬人穿著標準上班服飾與夏天休閒服飾於台北、台中、台南三城市的戶外進行輕量活動下的冷熱舒適感覺。結果顯示若著標準上班服飾於此三城市，則在3月及11~12月可感到最舒適；若著夏季休閒服飾則在5月及10月感到舒適，結果也可反映出各城市氣候與服裝間的舒適關連性。未來若能搭配檢驗儀器了解服裝的保溫性便能使用此舒適性模式針對此服裝的適用範圍進行評估和驗證。

This study established the comfort index of predicted mean vote (PMV) and predicted percentage dissatisfied (PPD) which based on the international standards ISO7730 by using MATLAB numerical simulation software. This comfort model needs seven parameters to assess the thermal comfort, including a person's metabolic rate, work, thermal resistance of wearing apparel, ambient air temperature, radiant temperature, relative humidity, and relative air velocity. To verify the confidence and applicability of this model used in Taiwan area, this study simulated that people wear Men's business suit or Men's summer casual suit with light activity in Taipei, Taichung, and Tainan cities. The results showed that the more comfortable period of years in these cities appeals in March and the middle time between November and December if wearing business suit. When wearing summer casual suit, the more comfortable period is located in May and October. The different comfort index between cities can also be reflected apparently. This suggested that it may do assessment of the apparel's applicable range by combining the comfort model with the test equipment.
