Novel phase-change heat insulation and moisture absorption building external envelope structure

Abstract

The invention discloses a novel phase-change heat insulation and moisture absorption building external envelope structure. The novel phase-change heat insulation and moisture absorption building external envelope structure comprises an outer wall, a roof and a bottom, wherein the outer wall is provided with an interface decoration layer, a wall phase-change material layer I, a wall basic layer, a wall phase-change material layer II, a wall airflow channel, a glass internal curtain wall and a turnover curtain wall which are sequentially arranged from the inside out; an air distribution pipe is arranged in the wall airflow channel on one side; a roof phase-change material layer, a waterproof layer, a cement layer, an inclined top surface and a ceiling are sequentially arranged above the airflow channel; a throttling and cooling device is arranged between the ceiling and the inclined top surface; a supporting and isolating mechanism is arranged under the bottom; and a moisture absorption phase-change material layer, a base layer, a heat insulation phase-change material layer and a baseplate are arranged above the supporting and isolating mechanism. The novel phase-change heat insulation and moisture absorption building external envelope structure has favorable heat insulation and moisture absorption effects, the bottom and the ground are isolated by a certain space area through the supporting and isolating mechanism, and together with the moisture absorption phase-change material layer, a favorable damp-proof role can be played, so that natural resources are reasonably utilized, and environmental protection and energy saving are achieved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a novel phase-change thermal insulation and moisture-absorbing building peripheral structure. Background technique [0002] In hot summer and cold winter areas in my country, due to the climate characteristics formed by its unique geographical location, the temperature in summer is high, and the number of days with a temperature higher than 35°C is 15-25 days, and the temperature on the hottest day can reach above 41°C. The annual average relative humidity Around 70%-80%, sometimes as high as 95%-100%. High humidity throughout the year and long dehumidification periods are a notable feature of the climate in this type of area. High humidity not only affects the thermal comfort of indoor personnel, but also affects indoor hygienic conditions, which adversely affects human health and the service life of indoor equipment and facilities. In order to meet the thermal comfort, healt...
