摘　　要：为计算广州某椭圆形建筑空调负荷。按建筑高及侧立面总面积不变,分别构建朝向比为1:20、1:2、1.6:1、2:1、20:1的平面正朝向建筑,采用冷负荷系数法计算各建筑14:00东西南北围护结构冷负荷,计算分析了椭圆建筑与平面正朝向建筑东南西北围护结构冷负荷相对误差,计算了椭圆建筑侧立面围护结构总冷负荷。研究结果表明,建筑高、侧立面总面积不变,在14:00,椭圆建筑与椭圆"相似建筑"东西南北围护结构总冷负荷相对误差|ε|≈3.2%,该椭圆建筑东西南北围护结构总冷负荷Qc≈3775.9 W。To calculate the air-conditioning load of an oval building in Guangzhou. According to the building height and the total area of the side facade remain unchanged, the planes with orientation ratios of 1:20, 1:2, 1.6:1, 2:1, 20:1 are constructed to face the building. Cooling load coefficient method is used to calculate the cooling load at 14:00, east, west,north and south enclosures, And the relative error of cooling load between the elliptic building and the envelope facing southeast and northwest of the building is calculated and analyzed. The total cooling load of the side facade envelope of the ova building is calculated. The results showed that the total area of the building’s high and side facades remained unchanged, At 14:00, the relative error of the total cooling load of the oval building and the oval "similar building" between the east, west, north and south envelope is about 3.2%, The oval building palisade structure between east and west, south and north total cooling load Qc≈3775.9 W.
