Description

technical field [0001] The invention relates to the field of traffic and transportation engineering, in particular to a method for optimizing operating parameters of a fluid heating and snow melting system. Background technique [0002] In northern China, the problem of snowmelt in snowy weather seriously restricts the safe and efficient operation of roads, bridges and airports. Currently used deicing methods such as deicing agents, snow removal vehicles, or manual snow removal all have certain limitations. Deicing agents have certain harm to the environment and building structures, and their performance is greatly affected by environmental factors; machinery Snow removal and artificial snow removal need to occupy the road, which affects the normal operation of roads, bridges or airports, and the snow removal efficiency is low. With the progress of snowfall, repeated snow removal is often required. In response to the above problems, scholars have developed a fluid heating r...
