The modelling of the inside temperature of the greenhouse depending on the sun radiation

In the paper the temperature processes in the greenhouse under two conditions have been studied: firstly if the water for plants is unreachable and secondly if there is enough water for plants. MATLAB and SIMULINK were used for analysis. The greenhouse has a complicated heating system. The analyses show that the microclimate controlling system is not able to warrant good conditions for plants in case the water for plants is unreachable. The analyses also show that if in the greenhouse there exists perfect air and soil humidity controlling system, the temperature for plants is not rising
