Thermal insulation structure of building

Abstract

The invention discloses a thermal insulation structure of a building, which comprises a wall body, a solar photovoltaic panel arranged on the outer surface of the wall body, and a battery, a water pump and a circulating water pipe connected with the solar photovoltaic panel, wherein the battery is electrically connected with the water pump; the wall body comprises a structure layer, a thermal insulation layer and a filling layer sequentially arranged from inside to outside; part of the circulating water pipe is arranged in the filling layer; one end of the circulating water pipe passes out ofthe filling layer and then passes through the ground to be connected with a water inlet end of the water pump; and the other end of the circulating water pipe passes out of the filling layer and is then connected with a water outlet end of the water pump. Water has a large specific heat capacity, the circulating water pipe is used to cool the wall body, and in comparison with the arrangement of the thermal insulation layer in the wall body purely, the cooling efficiency is higher; besides, in summer, the underground temperature is lower than that of the surface, in winter, the underground temperature is higher than that of the surface, after water in the water pipe flows underground to perform heat exchange with the underground, water temperature reduction effects are achieved in summer, water temperature rising effects are achieved in winter, water flows back to the wall body through the underground again and performs heat exchange with the filling layer, and the purpose of efficientthermal insulation is achieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a building insulation structure. Background technique [0002] my country is currently facing tremendous pressure on energy conservation and emission reduction. Building energy consumption accounts for about 24%-30% of the total energy consumption in the country, ranking first in energy consumption. Among them, energy saving of walls is the most important part of building energy saving. The outer wall of the building is the interface of building heat exchange, and the realization of thermal insulation technology and energy-saving materials has become the main way to achieve building energy conservation. In the prior art, materials with low thermal conductivity such as polystyrene, phenolic foam, polyurethane, etc. are usually used as thermal insulation materials to weaken the heat transfer process, but the thermal insulation effect obtained by the prior art is not ideal. The effect ...

Problems solved by technology

In the prior art, materials with low thermal conductivity such as polystyrene, phenolic foam, polyurethane, etc. are usually used as thermal insulation materials to weaken the heat transfer process, but the thermal insulation effect obtained by the prior art is not ideal. The effect can only increase the filling thickness of the insulation material, but this will increase the weight and volume of the building, so it is not advisable to simply use insulation materials for heat preservation
