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.
Highlights
Long-term meteorological observations clearly indicate that the climate is getting warmer
Extreme phenomena have a significant influence on climatic conditions, whose current increase in the number of occurrences noticeably changes the dynamics of climate features in Poland
Thermal phenomena that are unfavorable to humans include heat wavesor series of days with a maximum daily temperature exceeding 30°C [1, 2]
Summary
Long-term meteorological observations clearly indicate that the climate is getting warmer. The amount of sun energy possible to obtain in a given place is affected by the degree of cloudiness or air pollution For this reason, it is justified to perform local measurements specifying the solar energy resources. The local quality of atmospheric air depends to a large extent on the level of use of conventional energy sources This results in significant air pollution during the combustion of this type of fuels, primarily during the heating period [4, 12].
