To meet this demand, a Vapor Compression Cooling (VCC) is generally used in the cooling of air conditioning. The technology of Solar Cooling of Air SCA was used in this work to minimize the consumption of energy in Jordan, as well as to minimize the emission of Greenhouse Gases (GHG) that accompanies the burning of fossil fuel during the consumption of energy. The economic feasibility was analyzed in this work which has been done on the two scenarios of the system used. The RETScreen® software was used to perform the economic analysis of the proposed scenarios. The simulations results showed the relevance of the economic feasibility with a tariff of electricity, this is in addition to the reduction of emission compared with those (VCC) use electricity. Keywords— Solar Cooling by Air, Vapor Compression Cooling, Absorption, Adsorption. I. INTRODUCTION The temperature rising of climate change will lead to an increase in the cooling load and therefore consume more amount of energy in the air conditioning. All studies show that the technology of Solar Cooling by Air (SCA) has the possibility of reducing the consumption of electricity that by the end effect economic development. There is two SCA technology in Jordan, one of them is the Aqaba Residency Region (ARR) with a cooling capacity of ten kilowatts, which is the case study of this work. A. overview of SCA technology The most widespread chillers are absorption chillers as shown in Fig. 1. About 60% of the existing solar cooling systems is operating with absorption chillers and about 11% with adsorption chillers [1]. Almasri et al. [2] presented the analysis of economic feasibility between the VCC used in solar cooling with classical and electrical VCC, which are for “Absorption Chillers, Adsorption Chillers, and Desiccant Systems”. VCC Cycle is the most common device used in cooling systems [3]. The main idea of thermal SCA technology is to use different solar thermal collectors as a source of heat for the thermal drive chiller. An advanced system of adiabatic compressed air energy storage with a changing of ratio of pressure to improve the efficiency of the energy storage cycle of compressed air was presented [4]. The basic of the absorption chiller operation is almost like those for the normal VCC. The 3 units (absorber, pump, and generator) are instead of VCC compressor [5-7]. On the other hand, Ma et al. [8], used a cost benefit analysis to set Fig. 1 Thermally driven chiller market share [1] the best integration of the re-compression of carbon dioxide Brayton cycle with primary compression inter- cooling. Another study compared the effectiveness of multi effect absorption refrigeration systems. In this work, solar energy is used to provide power to the absorption cooling cycle in order to maximize the efficiency of the heat source used in the absorption system [9]. Kojok et al. [10] studied and analyzed the use of one of the hybrid cooling systems, which are an energy-efficient method of cooling buildings. This work will focus (for the first time in Jordan) on the economic visibility of using VCC cycles, which use an adsorption and absorption chiller for the process of refrigeration. The main objectives of this study are to provide an overview of various commercially available SCA technologies and analyze the economic feasibility of selected SCA technology in Jordan. II. ECONOMIC ANALYSIS OF 2 STAGES ADSORPTION CHILLER (2-SADC) To check whether the 2-SADC is environmentally and economically being convenient compared with VCC under the conditions of Jordanian markets, two scenarios are proposed using the RETScreen® software package. The two scenarios analyzed in this work are: 1. The first scenario is by assuming the solar energy and the CPC collectors represent the technology of heat- driven source, and the ambient (dry cooler) represents the technology of heat rejection. 2. The second scenario is by assuming the waste of heat represents the technology of heat-driven source, and the 2021 Third International Sustainability and Resilience Conference: Climate Change 978-1-6654-1632-0/21/$31.00 ©2021 IEEE 134 2021 Third International Sustainability and Resilience Conference: Climate Change | 978-1-6654-1632-0/21/$31.00 ©2021 IEEE | DOI: 10.1109/IEEECONF53624.2021.9668047 Authorized licensed use limited to: Rutgers University.
