根据寒冷地区人类居住特点,利用VB语言编程,以ISO7730为理论依据,通过PMV和PPD模拟计算了寒冷地区室内热环境,给出了寒冷地区人体不同代谢率条件下常规采暖和地板辐射采暖的舒适性温度。结果表明,在PPD≤20%的前提下,寒冷地区满足人体热舒适的室内常规采暖设计温度推荐值为20%,地板辐射采暖设计温度推荐值为19%,明显高于我国现行的设计温度。
根據寒冷地區人類居住特點,利用VB語言編程,以ISO7730為理論依據,通過PMV和PPD模擬計算瞭寒冷地區室內熱環境,給齣瞭寒冷地區人體不同代謝率條件下常規採暖和地闆輻射採暖的舒適性溫度。結果錶明,在PPD≤20%的前提下,寒冷地區滿足人體熱舒適的室內常規採暖設計溫度推薦值為20%,地闆輻射採暖設計溫度推薦值為19%,明顯高于我國現行的設計溫度。

According to the characteristics of human living in cold areas, the use of VB language programming, with ISO7730 as the theory basis. The paper simulates and calculates the cold regions indoor thermal environment through PPD and PMV. The paper gives the comfortable temperature of conventional heating and floor radiant heating in cold region under different metabolic rate conditions. The results show that, in PPD ≤20% under the premise, indoor conventional heating and radiant floor heating recommended temperature should be 20℃ and 19℃,which are higher than Chinese current design temperature.
