A device, named a geostill, was fabricated and tested for supplying greenhouse heating and pure water for irrigation, from salty geothermal water. A thermal analysis for this is presented and was tested experimentally, using geothermal water of different temperatures between 20 and 68 °C. A computer model was derived for calculation of water and heat yield of the geostill. Good agreement was found between theoretical results derived from the proposed model and experimental observation. It is concluded that the geostill makes a useful contribution to greenhouse heating and pure water production. For a layout of 0·5 m of geostill per m2 of greenhouse floor area and using geothermal water of 60 °C and mean greenhouse air temperature of 10 °C, geostill transfers heat of 135 W per m2 of greenhouse and during a 12 h night, yields 1·2 kg water per m2 of greenhouse. © 1992 Silsoe Research Institute. |
