Passive building graphite composite rock wool outer wall external thermal insulation system

Abstract

The invention discloses a passive building graphite composite rock wool outer wall external thermal insulation system. The system comprises a wall body; the external thermal insulation layer is arranged on the outer side of the wall body and comprises a first graphite polystyrene board, and first grooves are evenly formed in the side face, away from the wall body, of the first graphite polystyrene board; the first phase change material layer is filled in the first groove; the rock wool board is attached to the first phase change material layer; the second groove is filled with the second phase change material layer; a second graphite polystyrene board; the internal thermal insulation layer is arranged on the inner side of the wall body and comprises a thermal insulation board attached to the inner side of the wall body; a third phase change material layer; the heat conduction pipe is of an L-shaped tubular structure; the heat absorption plate is arranged on the outer side of the external heat preservation layer; and the transparent plate is arranged on the outer side of the heat absorbing plate. By arranging the phase change material layer, the heat preservation and insulation effect of the wall is improved, the indoor and outdoor temperature difference can be adjusted, energy is saved, and the comfort level of the indoor environment is improved.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an external thermal insulation system for passive building graphite composite rock wool external walls. Background technique [0002] Passive house, also known as passive energy-saving house, is an energy-saving building based on passive design. A building that does not require traditional heating methods and active air conditioning to achieve a comfortable indoor environment in winter and summer. The building does not actively introduce external energy, and relies on design and technology to reduce energy consumption to the greatest extent. A passive house does not require active heating, it basically relies on passively collected heat to keep the house itself at a comfortable temperature. Using the heat energy brought by the sun, human body, home appliances and heat recovery devices, etc., no active heat source is needed. [0003] At present, the main forms of wall insulati...
