Ground source heat pump heat storage heating system that uses shallow geothermal heat to instantly melt snowfall on airport runways

Abstract

The invention discloses a ground source heat pump heat accumulation and heating system capable of utilizing shallow geothermal energy to instantaneously melt snow on airport runways, in which three closed loops are formed to meet the requirements of different heating and heat accumulation modes. The snow removing method that the system utilizes the shallow geothermal energy as a heat source to heat the surfaces of the airport runways effectively overcomes the disadvantages of a traditional snow removing method. In a snowy season, the shallow geothermal energy in surrounding rocks near the airport runways is adopted to instantaneously heat the airport runways through heating tubes under the airport runways to melt the snow, so that the problem of snow accumulation on the airport runways at an airport in a northern area in winter is solved. The system solves the problem of ground temperature dropping caused by continuously using the shallow geothermal energy. In a non-snow season, a pipeline under the airport runways are used to collect heat on the surfaces of the airport runways generated by sun shine, and stores the heat in surrounding rocks near a ground heat exchanger, so as to realize utilization of solar energy across seasons and ensure the utilization efficiency and reliability of the shallow geothermal energy in winter.

Description

technical field [0001] The invention relates to an instant snow-melting system for an airport runway, in particular to a thermal storage heating system which utilizes shallow geothermal energy to melt snow and utilizes runway to collect heat and store solar energy. Background technique [0002] Our country has a vast territory, and there is snow or sleet in a considerable part of the area in winter. Especially in Northeast China, North China and Northwest China, the frequency and intensity of snowfall in winter are very high, and airports often delay flights due to snowfall. Therefore, timely removal of ice and snow is one of the heaviest tasks of the airport ground management department. At present, the commonly used snow removal methods for airport pavement mainly include mechanical snow removal by snow removal vehicles and chemical snow removal by chemical reagents. Among them, the mechanical snow removal method is slow and inefficient, and requires a lot of manpower an...

Problems solved by technology

[0004] This system uses shallow geothermal heat as a heat source, and the snow removal method of heating the runway effectively overcomes the disadvantages of traditional snow removal methods: in the snowfall season, the shallow geothermal heat in the surrounding rock near the runway is used for heating, and the runway is heated and melted immediately through the heating pipe below the runway Snowfall to solve the problem of snow accumulation on the runways of northern airports in winter;

[0005] At the same time, this system can solve the problem of ground temperature drop caused by the continuous use of shallow geothermal heat: in the non-snow season, use the pipeline running below to collect the heat generated by sunlight hitting the pavement, and store it near the buried pipe heat exchanger In the surrounding rock, realize the cross-seasonal utilization of solar energy, and ensure the efficiency and reliability of shallow geothermal utilization in winter
