摘要:
针对燃气热水器能效等级评价,选取典型样机,评价了不同样机在部分热负荷下热效率的变化规律以及热效率对能效判定的影响。结果表明:各样机热效率随着热负荷的减小而逐渐降低,60%额定负荷上时热效率变化为 2% ~5%,20% ~60%额定负荷下热效率的变化最大达到 8%;部分负荷下热效率差异对等级判定影响很大,特别是小负荷下容易造成误判。
Abstract:
Abstract: In view of gas water heater energy efficiency rating evaluation, by choosing the typical prototype, the paper analyzes the variation of the partload thermal efficiency of different prototypes and the influences of thermal efficiency on energy efficiency determination. The results show that with the reduction of the heat load in each prototype, the thermal efficiency reduces gradually. Thermal efficiency does not change significantly when the rated load is more than 60% and thermal efficiency changes significantly when the rated load is 20% -60%. The variation of partload thermal efficiency has a great impact on the level determination, especially it is easy to misjudge under small load.
