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.
Highlights
Energy is the driving media of technology
The problem stated that generating electricity, is the reason for humid conditions, and heat because of global warming, and the use of non-renewable energy such as fossil fuel and coal
To ensure enough coolant to compensate heat input, the gained heat was multiplied by factor of 1.6 in order to compensate the expected heat gains from other factors, and the cooling loss due to the frequent opining of the classrooms, and offices doors so, the total cooling load required to provide air conditioning for the building is 560 kW
Summary
Energy is the driving media of technology. Absent of energy, will create huge impact, on the whole societies. The problem stated that generating electricity, is the reason for humid conditions, and heat because of global warming, and the use of non-renewable energy such as fossil fuel and coal. Photovoltaic solar systems, were used, to produce electrical power, to cater cooling demands for buildings and facilities. The objective of this study, is to select, and use solar photovoltaic panels system, with operating parameters, to produce enough electrical power, to energize a cooling system, to supply coolant, for the engineering building, at Mutah University. To minimize the electric consumption, from the local grid, and contribute in carbon dioxide emission reduction, and to calculate the cooling load value, for the classrooms and offices, for the engineering building in Mutah University, and size suitable cooling system. The occupant of each classroom is 60 students. 1 person per office
