Transpired solar collector chimney tower

Abstract

A transpired solar collector chimney tower is provided. Specifically, disclosed herein is a transpired solar air heating collector device comprising: a heat absorbing roof; an interior space adjacent the heat absorbing roof; and, a plurality of air inlet openings distributed over the heat absorbing roof and configured to allow ambient air to flow from outside the heat absorbing roof into the interior space, a porosity of the heat absorbing roof due to the plurality of air inlet openings being in a range of about 0.25% open area to about 5% open area; a chimney tower extending from the transpired solar air heating collector device and connected to the interior space such that heated air in the interior space flows from the interior space through the chimney tower; and, one or more turbines positioned on a path of airflow from the interior space through the chimney tower.

[0001] Cross References to Related Applications [0002] This specification claims the benefit of priority to U.S. Patent Application no. 14 / 740389, filed June 16, 2015, and U.S. Patent Application no. 14 / 504740, filed October 2, 2014, both of which are incorporated by reference This article. technical field [0003] This specification relates generally to solar chimney towers, and in particular to osmotic solar collector chimney towers. Background technique [0004] Solar power moves the air, and the moving air can be directed to wind turbines to generate electricity. In a solar updraft tower or chimney, sunlight heats the air next to a very wide greenhouse-type covered collector structure (i.e., transparent and / or covered panels) surrounding a very tall chimney tower the central base. This heating causes convection, which moves air towards the tower through the stack effect. This air flow drives a wind turbine placed in or around the base of the chimney to generate ele...

AI Technical Summary

Problems solved by technology

[0006] Furthermore, in large areas the roof can easily accumulate dust, so the solar optical efficiency decreases over time due to dust accumulation, and / or the cover must be cleaned

In addition, the durability of such a transparent roof is low because it is difficult to reinforce the transparent board

In addition, glass panels may be easily damaged; and plastic or polymer covers used as tops will degrade over time when exposed to UV rays, and thin plastic sheets may be unraveled in high wind conditions

[0007] Such roofs also have thermal issues including low solar efficiency and low temperature rise affecting the general energy conversion of solar towers or chimneys

This inefficiency requires a larger solar collector area to generate more heat and air movement, resulting in higher investment costs
