【摘要】：針對夏熱冬冷地區(qū)冬季供暖問題,以空氣源熱泵+毛細(xì)管網(wǎng)地板輻射供暖系統(tǒng)為對象建立實驗系統(tǒng).實驗測試并分析了供水溫度分別為40℃,37℃,35℃,33℃和30℃時,不同供水工況毛細(xì)管網(wǎng)地板輻射供暖房間的室內(nèi)空氣溫度、各內(nèi)壁面溫度的變化特性以及室內(nèi)環(huán)境的舒適性.實驗結(jié)果表明:在重慶地區(qū),當(dāng)毛細(xì)管網(wǎng)輻射面積占地面的50%,毛細(xì)管網(wǎng)間距為20mm,填充層厚度為50mm的豆石混凝土,面層為12mm的木質(zhì)地板時,40℃,37℃,35℃,33℃和30℃供水工況穩(wěn)定時的室內(nèi)溫度分別為18.73℃,18.06℃,17.03℃,16.09℃和15.28℃;室內(nèi)熱感覺(PMV)分別為-0.65,-0.82,-1.09,-1.31和-1.44;不滿意百分率(PPD)分別為14%,19.08%,30.18%,40.71%和47.39%;各工況室內(nèi)豎直方向和水平方向上最大溫差分別為0.39℃和1.12℃.該地區(qū)供水溫度≥33℃時,室內(nèi)溫度可滿足舒適要求;供水溫度≥37℃時,室內(nèi)PMV和PPD滿足我國熱舒適評價標(biāo)準(zhǔn),各工況毛細(xì)管網(wǎng)地板輻射供暖系統(tǒng)室內(nèi)溫度分布非常均勻.
[Abstract]:In order to solve the problem of heating in hot summer and cold winter, an experimental system was established with air source heat pump capillary net floor radiant heating system as the object. The indoor air temperature, inner wall surface temperature and indoor environment comfort of capillary net floor radiant heating room under different water supply conditions were tested and analyzed when the water supply temperature was 40 鈩，
