L Pipes Geothermal

This idea is an improvement to conventional passive geothermal cooling to improve the volume of cool air produced for applications where a large volume of flow is needed. Applications where this may be of material assistance are buildings that utilize thermosiphon ventilation at the roof line, buildings where there is a substantial egress of air due to necessary openings (warehouses, retail) and applications where there is no air movement system. It may also be well baked but not to my knowledge.

The system is quite simple. A vertical pipe is mounted at the inlet of the geothermal pipe(s). The vertical rise of the pipe is tuned to produce the necessary volume of air. In this pipe water mist nozzle(s) are mounted in such a fashion as to evenly humidify the inlet air. Due to the increased density of the Humid air relative to the pressure on the far end of the L system the air "falls" down the pipe inducing flow and producing a cheap low energy source of humidified cold air. At the outlet end of the L a valve type humidistat regulates the pressure delivered to the mist system limiting the degree of humidification to whatever setting is desired.
