【摘要】：針對現(xiàn)行夏熱冬冷地區(qū)居住建筑節(jié)能設(shè)計標(biāo)準(zhǔn)中規(guī)定的連續(xù)用能方式與該地區(qū)實際用能情況存在嚴(yán)重偏離的問題,在該氣候區(qū)典型城市杭州開展居民空調(diào)用能行為的問卷調(diào)研,發(fā)現(xiàn)本地區(qū)居住建筑普遍具有間歇用能的特點,空調(diào)開啟行為受人體熱感受影響,室內(nèi)氣溫偏離人體舒適度范圍越大空調(diào)開啟率越高.然后,采用De ST建筑能耗模擬軟件分析不同類別用能方式下居住建筑外墻內(nèi)外保溫的全年節(jié)能效果.結(jié)果表明,在連續(xù)用能方式下,外保溫的全年節(jié)能效果優(yōu)于內(nèi)保溫;在不考慮容忍溫度的間歇用能方式下,內(nèi)保溫的全年節(jié)能效果優(yōu)于外保溫.容忍溫度可變的情況下,內(nèi)外保溫節(jié)能效果相同的容忍溫度臨界點為夏季31.8℃、冬季13.4℃.當(dāng)容忍溫度低于臨界點時,內(nèi)保溫節(jié)能效果更優(yōu);當(dāng)容忍溫度高于臨界點時,外保溫節(jié)能效果更優(yōu).合理規(guī)定節(jié)能設(shè)計標(biāo)準(zhǔn)中的空調(diào)運行工況是準(zhǔn)確評價外墻保溫措施節(jié)能效果的重要前提.
[Abstract]:In view of the serious deviation between the energy use mode stipulated in the current energy saving design standard of residential buildings in hot summer and cold winter area and the actual energy use in this area, a questionnaire survey on the air conditioning energy use behavior of residents in Hangzhou, a typical city in this climate area, was carried out. It is found that the residential buildings in this area generally have the characteristics of intermittent use of energy, the air conditioning opening behavior is affected by the human body thermal feeling, the larger the indoor temperature deviates from the human comfort range, the higher the air conditioning opening rate is. Then, the energy consumption simulation software of De ST is used to analyze the energy saving effect of exterior wall heat preservation of residential buildings under different kinds of energy use methods. The results show that the annual energy saving effect of external heat preservation is better than that of internal heat preservation under the continuous energy use mode, and the annual energy saving effect of internal heat preservation is better than that of external heat preservation under the intermittent energy use mode without considering temperature tolerance. When the tolerance temperature is variable, the critical point of tolerance temperature is 31.8 鈩，
