摘要
采用Airpak软件,对北京地区农村住宅低温散热器供暖系统的室内温度场、预计平均热感觉指数(PMV)、预期不满意百分率(PPD)进行模拟,热水由空气源热泵制取,供、回水温度为42、37℃。供暖室外计算温度(-7.6℃)条件下,人静坐高度水平面(1.2 m高度水平面)上平均温度为13.4℃,PMV的平均值为-0.29,PPD的平均值为5.47。实际室外温度(0.8℃)条件下,人静坐高度水平面上平均温度为16℃,PMV的平均值为0.08,PPD的平均值为5.68。低温散热器供暖系统的供暖期能效比为2.76。对于农村住宅,低温散热器供暖系统可满足热舒适性要求。
The indoor temperature field, predicted mean vote （PMV） and predicted percentage of dis-satisfied （PPD） of low temperature radiator heating sys- tem in a rural residence in Beijing region are simulated by Airpak software. Circulating hot water is produced by an air-source pump, and the temperatures of the supply and return water are 42 % and 37 % respectively. Under the condition of outdoor calculation temperature of -7.6℃, the average temperature of the level of people sitting height of 1.2 m is 13.4 % ,the average PMV is -0.29, and the average PPD is 5.47. Under the condition of actual outdoor temperature of 0.8℃,the average temperature of the level of people sitting height is 16℃, the average PMV is 0.08, and the average PPD is 5.68. The COP of the low temperature radiator heating system during heating period is 2.76. The low temperature radiator heating system can meet the thermal comfort requirements for rural residences.
