Abstract. Introduction. Currently, cooling residential buildings accounts for 20% of the world's total energy consumption, and this figure will increase to 25% by 2050. Therefore, reducing the specific energy consumption of building cooling systems is an urgent problem, and the use of renewable energy sources, in particular solar energy, in building cooling systems is the most rational solution. Methods and materials. In order to reduce the specific energy consumption in residential cooling systems, a combined evaporative cooling system based on solar photovoltaic modules has been developed, which operates entirely on solar energy and allows for simultaneous cooling and humidification of outside air to the required temperature based on a combination of an evaporative cooling device and solar photovoltaic modules. To determine the refrigeration load of the combined evaporative cooling system, a mathematical model based on heat balance equations has been developed and a numerical study has been conducted to determine the change in the indoor air temperature of the experimental house over time with a change in the intensity of solar radiation, outside air temperature and heat flows over time.
