Abstract

The invention discloses a passive energy storage solar ventilating system adopting a day-lighting solar heat collection technology. The passive energy storage solar ventilating system comprises a ventilating duct frame installed on a wall body, an outdoor side tempered double-layer glass cover and an indoor side tempered double-layer glass cover, wherein the outdoor side tempered double-layer glass cover and the indoor side tempered double-layer glass cover are parallelly fixed on the ventilating duct frame at a certain interval. Ventilating ports and air doors are arranged between the upper portions and the lower portions of the outdoor side tempered double-layer glass cover and the indoor side tempered double-layer glass cover and the ventilating duct frame. Rotary heat collecting and storing pieces are evenly arranged one side of the outdoor side tempered double-layer glass cover facing the indoor side tempered double-layer glass cover from top to bottom. The passive energy storage solar ventilating system utilizes solar energy resources to the most extent, reduces the building ventilation energy consumption, improves the building comfort, overcomes the shortcoming that an existing passive energy storage solar ventilating system cannot achieve day-lighting and meet the day-lighting demand. The passive energy storage solar ventilating system can be flexibly applied to office buildings, hospitals, residences and various buildings with high window walls, adopts a flexible and simple installing mode and has important significance on old building renovation projects.

Description

[0001] technical field [0002] The invention relates to the technical field of natural energy utilization, in particular to a passive energy-storage solar-energy ventilation system adopting daylight-capable solar heat collection technology. Background technique [0003] With the foreseeable rise in fossil energy prices and the need to reduce carbon dioxide emissions, many countries have introduced mandatory policies to increase energy efficiency while reducing the use of fossil energy. Among them, reducing building energy consumption is the key to achieve this goal: in Europe, building energy consumption can reach 37% of final energy in 2004; in the United States, it can reach 41% in 2002; in China, it can reach 40% in 2008 . An important way to reduce building energy consumption is to enhance the thermal insulation capacity of the building envelope and provide more stringent airflow organization and heat management. [0004] The passive ventilation design based on therma...
