变容量空调器的季节能效比的计算和分析

利用某变容量家用中央空调器性能参数,拟合出该空调器制冷量、输入功率、EER与负荷率的变化关系.利用我国近30年来的逐时气象资料,建立了广州、武汉、上海、杭州、重庆地区的温区统计数据,计算出了5个城市的季节能效比（SEER）.同时对武汉地区某空调器4个运行模式的季节能效比进行了计算,指出要反映空调器的实际运行条件下的季节能效比,还必须考虑空调器的实际运行时段.

Analysis and Calculation of the Seasonal Energy Efficient Ratio for a VRV Air-conditioner

The refrigerating capacity, input power are fitted as equations of temperatures, and the relation between the EER and load ratio are also acquired by using the performance parameters of a VRV air-eonditioner. The statistic data of temperature spans of Guangzhou, Wuhan, Shanghai, Hangzhou and Chongqing are established according to the meteorologic references of the recent 30 years of China. In addition, the statistic data of temperature zones of 4 operating mode in Wuhan are set up with the operating periods of air- conditioner. The paper calculates the value of the SEER in every city compared with the value of SEER of temperature zones defined . The results show that the climate conditions of the different areas exert obvious effect on the SEER. The results of the SEER in 4 operating modes for air-conditioner in Wuhan are analyzed, the practical operating periods of air-conditioner should be considered for reflecting the SEER of air-conditioner in the practical operating conditions are pointed out.
