Design a solar power air conditioning system for the engineering building at Mutah University

Abstract

Jordan like the other non-oil countries, spend significant amount of its budget on importing foreign energy. Also, the power demand increases due to, the population growth, in addition to hosting high number of refugees, from neighboring countries, and the enhancement of the citizen life style. The objective of this study, is to define the cooling load requirement, for the engineering building, at Mutah University, in order to analyze suitable cooling system, to cater the required cooling load. Energy analysis carried out, using the climate variables tabulated data, and Cooling Load Temperature Difference (CLTD), and Cooling Load Factor (CLF). The required power, to drive the cooling system was defined. Climate data shows that the average temperature was 33.2 °C, 32 °C and 33.3 °C in 2015, 2016 and 2017, respectively. The maximum temperatures was 38 °C registered in 2015. In this study the implementation of renewable energy, was considered by analyzing the viability of using, photovoltaic system, to provide power for the cooling system. Two options, to provide power for the system analyzed, the first option is supply the power from the grid, and the second option is, to supply the required power using photovoltaic power plant. The results show that, the cooling load of the building is 560 kW, and the required electrical power, to operate the cooling system is 224 kW electrical power. In addition, the results show that, the cost of power from PV system is, 40 % less than the cost of power from grid for the first 10 years. In addition, the payback period for the designed system is 5 years.

Performance Optimization of Solar PV System Utilized for Cooling System

“…The results of this study are consistent with the findings of Farajat et al [16]. The comparative analysis results indicated that the cooling load required equalled 560 kW, while the electrical energy needed to power the cooling system equalled 224 kW.…”

“…However, when the weather is cloudy and no sufficient solar radiation exists, their efficiency in cooling can remarkably decline. Farajat et al [16] carried out research to investigate the key role of solar PV system in providing cooling, depended on a comparative analysis. They compare the economic feasibility of two options to provide cooling.…”
