Performance of Greenhouse Coupled to Earth-Tube-Heat-Exchanger in Closed-Loop Mode
(2009-09-05)
An experimental greenhouse coupled to an Earth Tube Heat Exchanger (ETHE) in closed-loop mode has been installed at Kothara (23o 40' N 72o 38' E), India. Area is hot and extremely arid. ETHE is used to warm the greenhouse ...
Fourier Representation of Climatic Data of Kothara-Kutch
(2009-09-02)
Fourier series representations of some climatic variables were developed using data from the site of an experimental greenhouse at Kothara (Kutch). Hourly data was averaged over a month to yield a profile of an ...
