摘要:對夏熱冬冷地區江蘇省某研發中心被動式超低能耗辦公樓室內外環境參數進行為期7 d的實測,并對室內外熱濕環境參數進行線性擬合,考察了不同功能區的室內溫濕度及舒適性。結果表明:在夏熱冬冷地區室外大溫濕度差的干擾下,從逐時室內溫濕度來看,被動式超低能耗建筑室內溫濕度受干擾很小;但在過渡季逐漸轉夏季時,室內最高溫度間歇性達到28 ℃,相對濕度基本處于70%~90%,均值為72.5%,存在著濕度大且間歇性過熱的現象.良好的建筑密閉性和適當的通風是解決夏熱冬冷地區室內舒適度有效的被動式節能措施。

Abstract:The indoor and outdoor environmental parameters of a passive ultra-low energy office building in a research and development center in Jiangsu Province in the hot summer and cold winter area were measured for one week, and the indoor and outdoor thermal and humid environment parameters were linearly fitted. The indoor temperature,humidity and comfort of different functional areas were investigated. The results show that under the disturbance of outdoor large temperature and humidity in the hot summer and cold winter regions,the indoor temperature and humidity of passive ultra-low energy buildings are less affected by the indoor temperature and humidity. However,during the transition season when it gradually turns to summer,the indoor maximum temperature intermittently reaches 28 ℃,the relative humidity is basically between 70% and 90%,the average value is 72.5%,there is a phenomenon of large humidity and intermittent overheating. It can be concluded that good building tightness and proper ventilation are effective passive energy saving for solving indoor comfort in hot summer and cold winter areas.
