Development of Snow Melting Load Design Algorithms and Data for Locations Around the World
世界各地冰雪融化荷载设计算法和数据的开发
美国每年安装的融雪系统的安装成本估计为2亿至3亿美元。应用包括人行道、道路、坡道和跑道,系统包括循环、电气和红外设计。ASHRAE应用手册中给出的计算融雪系统设计加热要求的程序可能会大大高估设计要求。研究人员已经确定了可能影响融雪荷载的理论和经验考虑因素,但ASHRAE手册并未涉及这些因素。为了提供准确的设计指导,需要对这些因素进行彻底和系统的审查。本研究的目的是为工程师提供可靠的算法和足够的数据,以便在各种气象数据输入的情况下,计算广泛地区和国家的融雪负荷。

The installed cost of snow melting systems installed in the U.S. each year is estimated at $200 to $300 million. Applications include sidewalks, roadways, ramps, and runways, and systems include hydronic, electric and infrared designs.The procedures for calculating design-heating requirements for snow melting systems given in the ASHRAE Applications Handbook may significantly overestimate design requirements. Researchers have identified both theoretical and empirical considerations that may affect snow-melting loads but are not addressed by the ASHRAE Handbook. In order to provide accurate design guidance, these factors need to be thoroughly and systematically reviewed.The objective of this research is to provide engineers with reliable algorithms and sufficient data for calculation of snow melting loads in a wide range of locations and countries, with a variety of meteorological data inputs.PRINCAL INVESTIGATOR: James W.
