Low energy consumption integrated curtain wall building energy system and operation method thereof

Abstract

The invention discloses a low energy consumption integrated curtain wall building energy system and operation method thereof, and aims to provide a system and an operation method for collecting, transferring and storing low-grade renewable energy widely existing in curtain wall building by making full use of the curtain wall building's own enclosure structure and energy storage system. The systemcomprises a curtain wall enclosure structure, a first heat exchange system, a second heat exchange system and an energy storage system; the energy storage system communicates with the first heat exchange system and the second heat exchange system through a power device to realize the exchange and storage of cold or heat; the curtain wall enclosure structure positioned on the south side is sequentially provided with a photovoltaic glass component, an outer film layer, an outer curtain wall base glass layer, an air layer, a fixed mounting glass layer, an inner side film layer and an inner curtain wall base glass layer from outdoor to indoor. By the means of the invention, the widely existing low-grade renewable energy can be fully utilized to reduce energy consumption and save energy.

Description

technical field The invention relates to the technical field of building energy conservation, in particular to a building energy system and an operating method thereof for realizing the goal of low energy consumption of a curtain wall building. Background technique As we all know, the construction industry is actually one of the largest users of non-renewable energy, accounting for about 40 percent of the primary energy consumption of the world's major economies. Photovoltaic curtain walls are gradually being used in office buildings because they can solve part of the building's electricity load. However, due to the characteristics of the photovoltaic curtain wall building itself as a lightweight enclosure structure, the energy consumption has been high, and the solar cells in the photovoltaic curtain wall cannot be effectively cooled, which seriously restricts the improvement of its photoelectric conversion efficiency. In fact, the envelope structure is the main factor aff...

AI Technical Summary

Problems solved by technology

However, since glass is a lightweight enclosure structure, it has serious problems of heat insulation and solar radiation heat gain, which makes the indoor environment prone to serious thermal discomfort problems, so building energy consumption has not been effectively reduced
