Solar energy-driven passive reversing ventilating system

Abstract

The invention relates to a solar energy air exchange system and a convection drive reverse direction air exchange system thereof. Solar energy is utilized to heat the air and drives hot air to convect, the rising hot air due to convection drives the convection drive reverse direction air exchange device in the solar energy air exchange system to intake downwards fresh air outside to the inside from the top of a building, thus achieving the purpose of air exchange; the convection drive reverse direction air exchange system comprises a convection exhaust pipeline, a vane, a transmission mechanism, an air inlet pipeline and a supply fan, the rising convected air due to the solar energy heating enters the convection exhaust pipeline to drive the vane, the vane drives the transmission mechanism, and the transmission mechanism drives the supply fan, thus intaking fresh air outside to the inside thereof by the air inlet pipeline in the reserve direction.

Description

technical field [0001] The invention relates to the technical field of indoor and outdoor ventilation, and is a passive ventilation system driven by solar energy, especially a convective reverse ventilation system driven by solar energy, which uses solar energy to heat air, drives air convection, and convects hot air , drive the impeller in the convection exhaust pipe, the impeller drives the transmission mechanism, drives the intake fan in the intake duct, sucks the outside air into the intake duct, transports it in the direction opposite to the convection exhaust, and performs ventilation. Background technique [0002] In desert areas, there are generally abundant sunshine and hot and dry climate, especially in summer, when the ground and indoor temperatures are very high, which must be cooled down for human living activities, and the ground temperature often reaches above 40 degrees Celsius. Generally, outdoor air is used for natural convection The cooling method cannot b...

Problems solved by technology

[0002] In desert areas, there are generally abundant sunshine and hot and dry climate, especially in summer, when the ground and indoor temperatures are very high, which must be cooled down for human living activities, and the ground temperature often reaches above 40 degrees Celsius. Generally, outdoor air is used for natural convection The cooling method cannot be applied in desert areas

Although air conditioning was invented in the 20th century, it is extremely uneconomical and consumes a lot of energy to use air conditioning to cool down in desert areas
