摘　　要：对采用CO_(2)制冰系统的河北某场馆400 m大道速滑冰层的温度进行数值模拟,并进行冰层温度数据采集,验证CO_(2)制冰系统的实际运行效果。结果表明:模拟冰层表面温度在-5.77℃±0.30℃以内,实测冰层表面平均温度在-8.13℃±0.56℃以内,符合理论预期,可见采用CO_(2)制冰技术冰层温度均匀性较好、冰质优。The numerical simulation is conducted on the temperature of the 400 meter avenue speed skating ice layer in a stadium in Hebei using CO_(2)ice making system.In addition,the ice layer temperature data is collected to verify the actual operating effect of the CO_(2)ice making system.The results show that the simulated surface ice temperature is within-5.77℃±0.30℃,and the measured surface ice temperature is within-8.13℃±0.56℃on the average,which meets theoretical expectations.Thus the use of CO_(2)ice making technology has better ice temperature uniformity and excellent ice quality.
