COMPARISON AND ANALYSIS OF REAL SEER OF AIR CONDITIONER OPERATED IN DIFFERENT CITIES AND BY DIFFERENT OPERATIONS MODES

摘要

Real SEER of air conditioners’ changes with the local climate characteristics and practical work modes. In this paper, the 15 temperature zones from 24°C to 38°C were brought forward to calculating the SEER, which adapts to the climate characteristic in China. Two important temperature points are set respectively to express non-load temperature point and full cooling-load temperature point during refrigeration seasons. The hours-temperature datas of special cities, such as Shanghai, Wuhan, Chongqing and Guangzhou in China, were setup. Above datas and the datas of GB/T7725 China nominal temperature zones were analyzed .Based on the practical features of operation, four operational modes are proposed and the hours-temperature statistic datas of the four modes are set up in the city of Wuhan. The SEER of above four cities and GB/T7725 are calculated respectively according to their hours-temperature datas. In the same way the SEER of above four operational modes are also computed . The SEER to the same air conditioner in different cities and by different operational modes is different, and the influences on SEER are analyzed.
