Scheme of conditioning in room based on evaporative air cooling system using solar energy

Abstract

The article is devoted to the development of promising low-power evaporative cooling systems using solar energy. At the same time, the placement of elements of the system in determining the temperature, the humidity of the air in such indoor areas is determined by the parameters at which the most favorable conditions for the optimal climate in the room are created. The article presents the structural and thermodynamic parameters of the developed two-stage evaporative cooler air. The creating two-stage evaporative cooling installation is shown the efficiency and effectiveness of the cooling air. Given preliminary studies where study the possibility of indoor climate and presented their results. Requirements to ensure the indoor climate. The test evaporative air cooler with rotated regenerative heat exchanger has a design air capacity of 160 m3 / h and 200 W in the cold, it provides for an independent change in the rotation speed of heat exchangers, a change in the amount of sprayed water. The total consumed electric power is not more than 45 watts. Achieved cooling 7°C at an ambient temperature of 35÷40°C (July-August 2019).
