Air intake before the ground heat exchanger should have a funnel shape tapering towards the ventilation duct. This will increase flow over the GHE in the case of wind and the effect is achieved as air compressor.
Hewa ulaji kabla exchanger ya joto ardhi kuwa na mpare sura tapering kuelekea duct ya uingizaji hewa . Hii itaongeza zaidi ya GHE katika kesi ya upepo na athari ni mafanikio hewa compressor .
