Computer System for Microclimate Management in Closed Areas of the Post-Minning Galleries and Greenhouses

摘要

A number of authors determine the balance components - heat and water of the soil-plant-atmosphere system as the important characteristics of the plant growing in closed chambers. The evapotranspiration is the main and integral component of this balance and some authors propose (suggest) the Bowen ratio’ method for its calculation. Scientists increasingly require quantitative evaluation of the main climatic elements of the system “soil- vegetation-gallery atmosphere”, which has environments with varying sizes. Having computer systems, which can measure these climatic elements and calculate them, it is possible to organize the fully automated evaluation of their space distribution over all chambers' territories. The structure of the submitted microcomputer measurement systems suggests a direct and correct estimation of the energetic balance elements of the system “soil-vegetation-atmosphere”, based on distributed in space continuous measurements. Having data from measurements of the climatic elements, authors show how one can estimate the evapotranspiration and the heat flow as main elements of the energetic balance of the system “soil- vegetation- gallery atmosphere”, because they cannot be measured directly.
