Description
Technical Field
The utility model belongs to the technical field of the building, concretely relates to underground shallow civil air defense engineering outer wall heat collection system that buries.
Background
The city is a national or regional political, economic, cultural and traffic center, is a gathering place of population and materials, and is a target of attack in war. Thus, the fact that cities need protection is not a conflict. Civil air defense engineering is an important component of urban protection.
The general definition of civil air defense engineering is: the protective engineering can resist the killing damage of certain weapon effect and protect the life and property of people during war. China pays great attention to air defense engineering construction, and the air defense construction method can improve the national integral defense capability, improve the life line engineering of natural disaster resistance and air defense resistance of cities, and is also an important component of city construction. The combination of civil air defense engineering and urban construction comprehensively develops and utilizes the novel territorial resources of urban underground space, can exert the overall benefits of the city, relieve the important measures of a plurality of contradictions in urban development and is also beneficial to the sustainable development of the city. At present, the scale of development and utilization of urban underground space is continuously enlarged, and underground buildings such as subways, underground pedestrian streets, underground shopping malls, underground parking garages and the like which are built in large quantities in recent decades are gradually subjected to the strategic policy of 'peacetime combination'.
The protection requirement of the underground civil air defense engineering can be met without leaving the air-conditioning cooling system, and the normal operation of the air-conditioning cooling system is an important guarantee for a good thermal environment in an underground space.

Once during a war, the air conditioners in the buildings on the ground stop working, there is little heat generation, and as people and equipment are transferred to the underground part, a large amount of waste heat is generated in the underground part, and once the war breaks out, it will last for a long time, which will cause heat to accumulate in the concrete. Because the heat transfer coefficient of outer wall reinforced concrete layer is higher, the heat can transmit to ground fast to there is the risk of infrared exposure. On the other hand, during non-war periods, civil air-defense projects are often used in commercial, residential, etc. complexes, with air-conditioning on the ground running during the day and off at night. From the heat recovery properties of the soil: in the daytime, due to heat exchange modes such as convection and radiation with indoor air, the temperature of the outer wall body is increased and is close to the indoor temperature; at night, when the air conditioner does not work, heat is gradually diffused to surrounding rock soil due to the temperature difference between the air conditioner and the surrounding soil, and at the moment, the temperature of the outer wall on the ground is gradually reduced and approaches to the outdoor temperature; when the air conditioner is started again in the daytime, the outer wall with the lower temperature forms a heat load for the air conditioner.
