地域划分对变频空调器SEER值的影响

Influence of Region Zones on SEER of Variable-Frequency Air Conditioner

目前变频空调器在中国得到了广泛使用,故如何客观评价其能耗在当前十分重要。笔者参考美国、日本变频空调器SEER标准并结合我国气候实际情况,建议GB/7725-2002送审稿计算SEER值对我国地域进行划分。并以海信KFR-2601GW/BP变频空调器为研究对象,采用空气焓值法测试不同工况下空调器所消耗的功率和制冷能力。经过相关计算验证了地域划分会对SEER产生一定的影响,同一空调器在热带的SEER值要比在温、寒带低。

At present, variable-frequency air conditioner is widely used in China, so how to evaluate its energy consumption is very important. Based on SEER standard of USA and Japan, and combined with the actual climate condition in China, the advice of making region zones is proposed in the calculation of SEER in GB/7725-2002 in this paper. Hisense KFR-2601 GWP/BP is selected as the experimental object and air-enthalpy method is applied to measure the energy and refrigerating capacity of air conditioner at different working conditions. That region zone will yield certain influence on SEER of variable-frequency air conditioner is verified through calculation. For a same air conditioner, SEER value is lower in tropical zone than in temperate zone and frigid zone.
