Abstract

Meteorological analyzes unambiguously indicate climate warming. An increase in average air temperatures is recorded in both winter and summer. In recent years, an increasing number of hot and very hot days are observed, and the duration of series of days with maximum daily temperature above 30°C is also longer. Occurrence of hot weather adversely affects the person staying outside. The ever-increasing requirements related to thermal comfort, enforce the provision of appropriate conditions not only in the rooms, but also in the external zones of people. Cooling the air in outdoor zones using standard air-conditioning systems can be expensive due to the high demand for electricity. Ensuring cooling through the use of renewable energy, such as solar energy, is a key solution to energy and environmental problems. In this article, the technical potential of solar radiation energy was determined based on data from the Rzeszow- Jasionka meteorological station and the possibilities of using solar energy in air cooling systems in external zones were presented.
