COMPARISON OF POLYNOMIAL REGRESSION AND LINEAR INTERPOLATION AS METHODS FOR TEMPERATURE DISTRIBUTION STUDIES UNDER GREENHOUSES |
| Authors: | S. Vanhoutte, H. Verlodt |
| Abstract:
The temperature distribution under greenhouse has been studied by simultaneous temperature measurements in different points of vertical (27 points) or horizontal (45 points) sections. The calculation of the isotherms in the different sections of the greenhouses has been realised by means of both bidimensionnal polynomial regression and linear interpolation. Comparison of the plotted images shows the differences. A comparative analysis of the results with both methods and the deviation between the calculated image and the temperature measurements has been realised. For vertical distributions the polynomial regression gives results with similar precision as the linear interpolation, but for horizontal distributions the linear interpolation seems to be the most accurate method. | |
