Synthetic jet and heat and electricity dual supply solar wall ventilation system

Abstract

The invention provides a synthetic jet and pyroelectricity double-supplied solar energy wall ventilating system. A thermoelectric device provides energy supply for a synthetic jet device to control and replenish the flow in the solar wall. In sunny days, a solar wall provides fresh air for indoor and promotes air circulation. The thermoelectric device transforms heat into electricity to provide energy for an array synthetic jet, at this time, and the synthetic jet can spray air for a vortex zone (an air stagnation zone) to improve an air flow structure in a channel to increase ventilation quantity. When the sunlight is not sufficient or at night, electricity is supplied to a synthetic jet actuator and the thermoelectric device by an external power grid, not only can the prycelectric deviceheat the interior of a channel, but also the power of air circulation is provided, at the same time, and the synthetic jet adjustment direction is subjected to post injection for the flow. In this way, the combination of solar energy and external network provides an efficient treatment system for improving the indoor ventilation environment, and the problems that the indoor flow structure is notgood when sunlight exists and the solar wall cannot work in the absence of sunlight are solved.

Description

technical field [0001] The invention relates to an indoor ventilation system, in particular to a solar wall indoor ventilation system with synthetic jet technology and thermoelectric technology. Background technique [0002] Nowadays, solar chimney technology is more and more applied to buildings due to its excellent energy-saving characteristics, and solar wall is an example. The solar wall is a ventilation-enhancing system of transparent glass channels connected to interior vents. When sunlight shines on the wall, the air in the channel is heated, and the temperature difference between inside and outside becomes the source of air flow. The traditional solar wall has a single source of energy, which can only promote indoor ventilation when the sun is shining, and its function is greatly reduced or even unable to work when it is cloudy or rainy. Therefore, it is necessary to supplement the energy of the traditional solar wall to meet the needs of indoor ventilation under v...
