At present, thermal management in greenhouses is an important task for the greenhouse industry. This is facilitated by assessing heat loss through the greenhouse enclosing structures, which is an important component of energy management when designing a greenhouse, taking into account local climatic conditions. In this work, for the first time, a mathematical model is proposed for studying the behaviour of the dependence of the air temperature in a solar-fuel trench-type greenhouse in the climatic conditions of Uzbekistan. Since, at present, there is no thermal technical assessment of the microclimate of a solar-fuel trench-type greenhouse for the climatic conditions of the regions of Uzbekistan. The study aims to develop a mathematical model of the thermal regime and microclimate in a solar-fuel trench greenhouse. To check the reliability of the proposed mathematical model, experimental measurements of the air temperature inside the greenhouse were carried out. The accuracy of the proposed mathematical model of a solar-fuel trench-type greenhouse was estimated using the methods of "standard deviation" and the square of the correlation coefficient. As the results show, the standard deviation is equal to 1.5 °C, the standard deviation in percent is equal to 7.2% and the square of the correlation coefficient is 0.86.
