Experimental Verification of a Mathematical Model for the Temperature Mode of a Solar-Fuel Trench-Type Greenhouse

A mathematical model for nonstationary heat balance is presented in the paper. It is used for investigating the indoor air temperature behaviour in a solar-fuel trench-type greenhouse. The microclimate of a solar-fuel trench-type greenhouse is estimated from the heat engineering point of view for Uzbekistan climate conditions. For verifying the presented mathematical model, we measure the air temperature inside the greenhouse built at the experimental site of Tashkent State Technical University. The accuracy of the presented mathematical model for a solar-fuel trench-type greenhouse is estimated by using the “standard deviation” method and correlation coefficient square. As the results show, the standard deviation is equal to 1.5°С, the standard deviation in percent is equal to 7.2% and the correlation coefficient is 0.86.
