*** General Introduction ***

The data presented in this study comprises information gathered during the development of an absorption solar cooling system. This research project became feasible through a grant (approval) awarded by the University Research Projects Council in Algeria (PRFU) under the reference number: (B00L02UN410120190003). The primary focus of this project revolves around simulation and modelling, with the utilization of the TRNSYS18 software (userld:18-T0272)
This absorption solar cooling system is designed to harness solar energy for cooling purposes, representing a vital step towards sustainable and energy-efficient cooling solutions

***Purpose of the Research and Data Collection***

The primary objective of this research and data collection endeavour was to develop an innovative and efficient absorption solar cooling system. This system aims to provide the necessary cooling load for the Laboratory Building (LPMR) located at the University of Souk Ahras.The successful development of such a system can significantly contribute to sustainable building practices.

***Description of the Data in this Dataset***

To compile a comprehensive dataset and extract valuable insights, the following steps were undertaken:

1-	Climate data for the specific location of the study were extracted using Meteonorm8 software . These data are structured in the (.tm2) format and provide extensive weather information on an hourly basis for an entire year, offering critical insights into local climate conditions.	
2-	A three-dimensional building model, faithfully simulating the Laboratory Building under investigation, was meticulously designed using SketchUp 2019. Details of this model were preserved in an (.idf) file format, enabling seamless integration with the TRNBuild software. This integration facilitates the monitoring and control of various building parameters, a fundamental aspect of the study.
3-	The building model was then incorporated into Transys Studio (Importing the building model into Simulation Studio). Subsequently, it was equipped with various components constituting the proposed solar cooling system (types). The entire project was stored in the tpf format for comprehensive system analysis and evaluation.
4-	Specific areas where parameter values vary were identified, and these areas were subject to thorough analysis using Minitab19 software. This analysis aimed to formulate proposed experiments for optimization, addressing critical aspects of the solar cooling system's performance:

                                  parameters    	Levels
		                                (1)	(2)	(3)
                         A	 Area(m²)	10	80	150
                         B	Slope(°)	20	30	40
                         C	Volume(m³)	4	9	15
                         D	Flow(Kg/hr)	100	500	900

5-	A total of 25 proposed experiments were meticulously executed, yielding results denoted as SF&Eff (Solar Fraction and Efficiency). These results were subsequently subjected to further analysis using Minitab19. This in-depth statistical analysis encompassed the identification of the most influential factors, determination of optimal values, exploration of correlated and independent variables, and more. The outcomes of this analysis, whether presented in tables or graphical representations, were carefully documented in the mpx file format.
The comprehensive analysis of these results plays a pivotal role in guiding the refinement and optimization of the proposed absorption solar cooling system, ultimately contributing to the advancement of sustainable cooling technologies.
