间歇供暖房间有效能耗影响因素分析
Influencing factors of effective energy consumption in intermittent heating rooms
摘要：
在人工气候室内，对热风间歇供暖房间的空气温度、围护结构内表面温度、蓄热体（家具）表面温度和能耗进行了实测，提出了有效能耗的概念，对其影响因素进行了实测和分析。结果表明：蓄热体蓄热在供暖全过程中均降低了有效能耗占总能耗的比例；供暖功率、室内外温差和供暖时长对室温上升阶段的总有效能耗减小率和室温平稳阶段的无效能耗比产生不同影响。
Abstract：
Measures the indoor air temperature, inside surface temperature of envelope, surface temperature of thermal mass and energy consumption of the intermittent heating room in an artificial climate chamber. Presents the concept of effective energy consumption (EEC), and measures and analyses its influencing factors. The results show that the proportion of EEC in the total energy consumption is decreased by the heat gain of the thermal mass in the whole heating process. The heating power, air temperature difference between indoor and outdoor and length of heating time have different impacts on the decrease rate of total EEC in the air temperature rising period and the proportion when invalid energy consumption in the period when stable air temperature.
