Abstract

The invention provides a heat pipe heating and fluid heating composite type pavement snow melting system and an operation control method thereof and relates to the technical field of airport pavementsnow melting systems and operation strategies. The problems of low snow removing efficiency, serious environment pollution, large pavement damage and large energy consumption of an existing airport pavement snow removing method are solved. Multiple gravity type heat pipes of a heat pipe heating system are placed in a pavement structural layer and an underground soil layer in parallel; a condensingsection, a heat insulating section and an evaporation section of each gravity type heat pipe are connected with each other in sequence from top to bottom; the condensing sections are obliquely placedin the pavement structural layer; the evaporation sections are vertically placed in the underground soil layer; liquid storage tanks are arranged at the lower parts of the evaporation sections; and afluid heating system comprises an underground heat taking system, a heat pump unit and a pavement system; the heat pump unit is positioned between the underground heat taking system and the pavementsystem. According to the heat pipe heating and fluid heating composite type pavement snow melting system, the operation cost of the fluid heating system is reduced; and meanwhile, the temperature application domain of the heat pipe heating system is expanded.

Description

technical field [0001] The invention relates to the technical field of an airport pavement snow melting system and its operation strategy, in particular to a heat pipe heating and fluid heating composite pavement snow melting system and an operation control method thereof. Background technique [0002] More than 100 airports in my country are in the snow belt. The problem of snow and icing on roads in winter has become the main factor restricting the safe operation of airports. The main reason is that the existence of the ice and snow layer reduces the friction coefficient between the tire and the road surface, which can easily cause flight accidents. [0003] Existing snow and ice removal technologies for airport pavement mainly adopt mechanical snow removal, chemical snow melting and electric heating snow melting and so on. Among them, the efficiency of mechanical snow removal method is low, and the removal is not thorough, and it is easy to generate a thin ice layer on ...
