Heat insulating wall structure of passive house

Abstract

The invention discloses a heat insulating wall structure of a passive house. The heat insulating wall structure comprises a base wall, a graphite polyphenyl board layer, an alkali-resisting fiber netlayer, a crack resistance mortar layer and a wall internal water circulation device, wherein the wall internal water circulation device comprises a water circulation pipeline, a water storage tank, awater inlet pipe, a water return pipe, a water changing pipe and an electric heating device. The graphite polyphenyl board in the wall structure adopts high heat insulation insulating materials, so that the indoor temperature can be guaranteed to be constant for a long time, the effect of energy saving is achieved; the alkali-resisting fiber net layer and the crack resistance mortar layer are arranged, so that indoor air tightness is further enhanced, and the indoor temperature is maintained to be free from waste to the maximum degree, and energy saving is facilitated; the wall internal watercirculation heating device is arranged, so that water flows circularly, through the specific heat capacity of water, the temperature in the base wall is maintained to be constant, further the indoor temperature is changed and maintained, and the effect of constant temperature is realized; and through a solar power generation device, energy is supplied to elements, so that energy is saved, and theheat insulating wall structure is green and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of passive houses, and more specifically relates to a thermal insulation wall structure of a passive house. Background technique [0002] A passive house is a master of various technical products, a house where the sum of all primary energy consumed does not exceed 120 kW·h / (square meter. year) by making full use of renewable energy. Such a low energy consumption standard is achieved through high thermal and acoustic insulation, a highly airtight building exterior and renewable energy. [0003] Building thermal insulation is an important part of building energy conservation, which is to improve the thermal insulation performance of the building itself. Some existing building exterior walls use 8-10cm extruded board or polystyrene board, which has a high thermal conductivity and is laid on a single board, which has poor thermal insulation effect and poor air tightness. The air exchange volume is large, and ...

AI Technical Summary

Problems solved by technology

Some existing building exterior walls use 8-10cm extruded board or polystyrene board, which has a high thermal conductivity and is laid on a single board, which has poor thermal insulation effect and poor air tightness. The air exchange volume is large, and the temperature in the house cannot be guaranteed. It is hot in summer and cold in winter.
