Indoor solar secondary ventilation and heating system

Abstract

The invention provides an indoor solar assisted ventilating and heating device, which relates to a building energy saving device which uses the solar energy to promote indoor ventilation and heating. The device consists of a sunshine well, an assisting ventilating fan and an outer window or the outer window and a minisize ventilating fan. The device has a simple structure and low cost and integrated with a building into a whole, and can satisfy the requirements on indoor assisting ventilation, heating and heat insulation in the daytime or at night in summer, in the daytime or at night in winter and in the transitional season by using the solar energy, thereby effectively using natural resource and reducing the building energy consumption. The device can be widely applicable to different regions such as the south where is warm in winter and hot in summer and the north where is cool in summer and cold in winter, and can be widely used as the indoor assisting ventilating and heating system of the buildings such as residential buildings, commercial buildings, commercial residential comprehensive buildings, office buildings and working and teaching comprehensive buildings and the like.

Description

1. Technical field: [0001] The invention belongs to the technical field of building ventilation and heating, in particular to a building energy-saving device that utilizes solar energy to promote indoor ventilation and heating. 2. Background technology: [0002] According to incomplete statistics, my country's building energy consumption has reached 27.5% of the total energy consumption at present, and this figure will continue to increase with the rapid development of my country's construction industry. Therefore, with the establishment of the basic national policy of energy conservation and emission reduction, the development of building energy conservation work is even more significant. According to the country's goal of achieving 65% energy saving in buildings, in addition to improving building enclosures to achieve energy savings of 30% to 35%, energy-consuming equipment and systems must also achieve energy savings of more than 30%. Therefore, it is necessary to fully ...
