展会介绍：
美国奥兰多空调、供暖和制冷展International Air -Conditioning、Heating、Refrigeration Exposition 简称：AHR是由美国供暖、制冷和空调工程师学会(ASHRAE)和美国制冷空调协会( ARI )主办，美国国际展览公司(International Exposition Co.)承办。首届展览会举办于1930年，是北美地区历史久、规模大的空调、供暖及制冷产品的交易展，每年一届。该展汇集新产品、新理念、新服务于一体，吸引了大量的专业人士到场参观。
现场火爆：上届美国空调、供暖和制冷展AHR EXPO在美国亚特兰大举行，共有来自全球100多个国家的5000多家参展商。有来自全球160多个国家的118582名专业观众与买家参加该会。68家赞助和支持单位进行全球宣传。我国参展商有：美的、海尔、TCL、志高、奥克斯、扬子、格兰仕、海信·科龙、美芝、东贝、中化集团、贝莱特、奇威特、金龙、海亮等300多家企业参与该次展会，均取得较好的效果，95%企业反馈还会继续参加下一届展会，使得AHR EXPO已成为国内企业参加外展的首选展会。
专业度高：美国空调、供暖和制冷展给所有参会者提供一个交流学习的平台，来自业内的专业人士以及相关产品协会的专家将免费提供讲座、座谈机会，主题从商业运营到当前的科学技术发展等，覆盖领域广泛;同时，展会还设立了建筑自动化控制成品展示区，包括辅助管理系统、自动建筑系统、能量管理系统、气候控制监控等的展示以及软件中心区，包括产品的设计，计算机辅助设计系统，商业管理系统，能量分析，软件程序及升级等。在专业展行业里，只有美国制冷展能够做到每年一届的盛大展出，并且展出优质效果。
需求量大：据美国奥兰多空调、供暖和制冷展参展反馈：近年来，我国制冷空调和供暖行业快速发展，制冷空调产品除满足国内市场需求外，还不断扩大进入国际市场的比例。因此,跟踪国际制冷空调技术发展动态，加强制冷空调设备制造及应用领域的对外交流与合作，对促进我国空调、供暖和制冷产品的出口已十分必要。
