Estimation of Real Seasons in a Semi-Arid Region, Ghardaia, Case Study

Abstract

For any new applicable and profitable investment in the thermal field of any region, we aim to eliminate or renovate conventional heating and air conditioning systems with new systems, which will work with new energies or renewable. First, you need to know the climate characteristics of these regions. In this study, we determine the diagnosis of the climate of arid and semi-arid regions, taking Ghardaï a as an example. These concerns air conditioning, heating, cold, ventilation, thermal water, for all this, we use the data from the two weather stations located on the Terrace of our research unit applied to renewable energies (URAER), Ghardaï a, for the last five years (2012)(2013)(2014)(2015)(2016), to calculate the day degrees heating and air conditioning (DJC and DJF) and the obtained results have been compared with the RET Screen motor from (1980_2006). Our approach allows us to discover a simple graphic method to characterize the seasons of Ghardaï a; applicable for any region around the world. In addition, it allows the real determination of the hygrothermal comfort of the region as well as the thermal characteristics of the MCPs adaptable to the Saharan climate.
