Building double-layer energy-saving window structure and energy saving method thereof

Abstract

The invention discloses a building double-layer energy-saving window structure and an energy saving method thereof. An external window unit is formed by two layers of windows, i.e., an inner window and an outer window; one external window unit can be separately arranged, or a plurality of external window units are continuously arranged in parallel. The inner window is made from a bridge-cutoff aluminum alloy frame material and hollow glass; a double-layer energy-saving window is provided with a cavity, and the cavity is internally provided with an electrically-lifted rotary shutter curtain; the outer window is made from an aluminum alloy frame material and a single layer of glass. The building double-layer energy-saving window structure can effectively reduce the numerical value of a heat transfer coefficient of the outer window, fully utilizes the sunlight so as to achieve an ideal energy-saving effect, can effectively reduce the influence of building outdoor noise on the interior of a room, and can improve and adjust the indoor light environment by means of the electrically-lifted rotary shutter curtain in the cavity so as to improve the indoor environmental quality; the building double-layer energy-saving window structure can be flexibly installed, enriches the architecture modeling design and improves the whole quality of a building.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of architectural design, and in particular relates to a double-layer energy-saving window structure and method for a building. [0003] 【Background technique】 [0004] In today's world, energy conservation has become the theme of the times. my country's building energy consumption accounts for more than 27.8% of the total energy consumption of the whole society. As the weakest link in energy conservation in the building envelope, external windows rank first in energy consumption. Therefore, energy-saving exterior windows have become a hot issue in the field of building energy conservation. Existing building exterior window products are mostly single-layer exterior window systems using single-layer insulating glass, with high heat transfer coefficients. Although they can meet the most basic lighting and energy-saving requirements for enclosure structures, they cannot achieve sunlight protection. If it is fully...

Problems solved by technology

Existing building exterior window products are mostly single-layer exterior window systems using single-layer insulating glass, with high heat transfer coefficients. Although they can meet the most basic lighting and energy-saving requirements for enclosure structures, they cannot achieve sunlight protection. Fully utilized, unable to meet better energy-saving requirements for external windows and requirements for improving indoor light environment

In addition, under the existing external window system, the size and form of windows on the building's facade are greatly restricted, which has greatly restricted and affected the architectural shape and the indoor environment of the building.
