The article develops a mathematical model of the modes of change of the indoor air temperature and the loaded biomass temperature over time on the basis of the equilibrium heat balance equation of the reactor of the heat pipe biogas-biofertilizer. Theoretical and experimental studies of changes in air temperature over time in stationary and non-stationary states inside the reactor of a thermal tubular biogas-biofertilizer. According to the results of the study, when the outside air temperature is 10 °C, it is possible to heat the indoor air temperature to 85-90 °C in accordance with the total solar radiation falling on the transparent surface of the device reactor. It is scientifically based to achieve full coverage of the greenhouse heat load using heated water due to the combustion of biogas obtained anaerobically in a water heating boiler as a result of heating of the biomass inside the device.

This article presents the results of experiments on the temperature and humidity regimes in the drying chamber when drying apples and apricots in a refrigerator with a combined solar collector and heat pump. The combined dryer is designed for simultaneous drying and long-term storage of the product. Experiments on the study of temperature and humidity regimes were carried out under natural convection conditions. Experimental studies of temperature and humidity regimes showed that the maximum temperature inside the chamber reached 46 oC and the maximum humidity reached 62%, and in these temperature and humidity regimes, apples were dried in 30 hours and apricots in 48 hours. From a product with a starting mass of 5 kg, 0.65-0.7 kg of dried product was obtained. Experimental results on temperature and humidity during drying of apples and apricots t=f(h) and w=f(h) and presented in the form of a dependency graph.

In this work, an analysis of the thermophysical processes taking place inside a specially designed chamber with a geometry different from other works was carried out. This process is designed in COMSOL Multiphysics software. Boundary conditions were investigated for ambient temperature of 293.15 K and solar radiation of 1000 W/m2. The process was taken as natural convection. In this case, the flow of air with high humidity inside the solar water heater was analyzed. It can be seen that the air temperature rises to 450 K. At the same time, the speed of moist air inside the chamber, heat flow and other thermophysical quantities were determined and analyzed.
