Transparent Windshields for various vehicles, such as cars, rail vehicles including trains, streetcars, and locomotives,**snowmobiles, airplanes, helicopters and sea vessels, must be deiced or defrosted using available on-board power. Typically,**deicing and defrosting are accomplished by blowing air heated by the vehicle's engine onto the windshield. However, especially**since the engine is initially cold upon startup, deicing/defrosting takes a considerable amount of time with unnecessary emission of**greenhouse gases to the environment. Pulse-electro thermal deicing (PETD) is a technology that can solve this problem. It uses a**high density of heating power (W/m2) using proprietary pulse and frequency, which allows for rapid and energy-efficient deicing.**The pulse and frequency are calibrated based on a number of factors such as temperature, type of ice growth, etc., and melt a thin**interfacial layer (~50 microns) of ice rapidly and energy efficiently. This detaches the ice, without having to expend the time and**energy to melt all the ice. It is the purpose of this project to develop, test and validate the use of PETD technology for automotive**windshield defrosting/deicing. The successful validation of this technology in the above mentioned applications will have**tremendous effect on energy saving as well as the reduction of greenhouse gas emission to the environment.**.**Ontario

各种车辆的透明挡风玻璃，例如汽车、轨道车辆（包括火车、有轨汽车和机车）、雪地摩托车、飞机、直升机和海船，必须使用可用的车载电源进行除冰或除冰。通常，除冰和除霜是通过将车辆发动机加热的空气吹到挡风玻璃上来完成的。然而，特别是 ** 由于发动机在启动时最初是冷的，除冰/除霜需要相当长的时间，并且不必要地向环境排放 ** 温室气体。脉冲电热除冰（PETD）是一种可以解决这一问题的技术。它使用 ** 高密度的加热功率（W/m2），使用专有的脉冲和频率，可以快速高效地除冰。**脉冲和频率基于诸如温度、冰生长的类型等的多个因素来校准，并且快速且节能地融化薄的界面层（~50微米）的冰。这样就可以将冰分离，而不必花费时间和精力来融化所有的冰。本项目的目的是开发、测试和验证PETD技术在汽车挡风玻璃除冰/除冰中的应用。该技术在上述应用中的成功验证将对节能和减少温室气体排放产生巨大影响。安大略
