“…Khan et al [47] found out that based on various collector areas, for Chennai city, the solar desiccant-assisted Dedicated Outdoor Air System (DOAS) integrated radiant cooling system could achieve 7.4% to 28.6% energy savings in comparison with the cooling coil-assisted DOAS radiant cooling system. In the last several decades, solar-assisted cooling technology has widely been evaluated worldwide, including solar electric cooling powered by PV [15][16][17], solar absorption cooling [18][19][20][21][22][23], solar adsorption cooling [24,25], and solar desiccant cooling [26][27][28][29][30][31][32][33][34][35]. A theoretical modelling with experimental validation studied by Nie et al [36] demonstrated that the solid desiccant cooling assisted by heat pump was more efficient than the conventional cooling system due to high efficient dehumidification capacity.…”

Abstract:This study has investigated the feasibility of three different solar-assisted air conditioning systems for typical medium-sized office buildings in all eight Australian capital cities using the whole building energy simulation software EnergyPlus. The studied solar cooling systems include: solar desiccant-evaporative cooling (SDEC) system, hybrid solar desiccant-compression cooling (SDCC) system, and solar absorption cooling (SAC) system. A referenced conventional vapor compression variable-air-volume (VAV) system has also been investigated for comparison purpose. The technical, environmental, and economic performances of each solar cooling system have been evaluated in terms of solar fraction (SF), system coefficient of performance (COP), annual HVAC (heating, ventilation, and air conditioning) electricity consumption, annual CO 2 emissions reduction, payback period (PBP), and net present value (NPV). The results demonstrate that the SDEC system consumes the least energy in Brisbane and Darwin, achieving 56.9% and 82.1% annual energy savings, respectively, compared to the conventional VAV system, while for the other six cities, the SAC system is the most energy efficient. However, from both energy and economic aspects, the SDEC system is more feasible in Adelaide, Brisbane, Darwin, Melbourne, Perth, and Sydney because of high annual SF and COP, low yearly energy consumption, short PBP and positive NPV, while for Canberra and Hobart, although the SAC system achieves considerable energy savings, it is not economically beneficial due to high initial cost. Therefore, the SDEC system is the most economically beneficial for most of Australian cities, especially in hot and humid climates. The SAC system is also energy efficient, but is not as economic as the SDEC system. However, for Canberra and Hobart, reducing initial cost is the key point to achieve economic feasibility of solar cooling applications.

“…According to [4], the recommended storage capacity for a solar cooling system is 50-100 L/m 2 of the collector area. This can act as an indication and guidance to choose the values for the storage tank volume sensitivity analysis.…”

“…The working principle of the solar desiccant cooling system is that the desiccant material in the desiccant wheel first dries and heats the outside air (1)(2), then the dehumidified process air is cooled to near ambient temperature through a sensible air-to-air rotary heat exchanger (2)(3). The process air is further cooled by the evaporative cooler (3)(4) and is eventually sent to the conditioned space. In the regeneration air stream, the return air is cooled by a second evaporative cooler (5-6) in order to increase the heat exchanger's efficiency.…”

“…The best solution for achieving the economic feasibility of the solar desiccant cooling system was the installation of 16 m 2 evacuated tube collectors, which allowed 50.2% primary energy savings and 49.8% CO 2 emissions reduction compared to the referenced conventional system, with about 20 years payback period. Rafique et al [4] conducted a theoretical analysis of desiccant-based evaporative cooling systems for five cities in Saudi Arabia. They found that the system thermal COP ranged from 0.275 to 0.476 based on different locations.…”

Solar desiccant cooling is widely considered as an attractive replacement for conventional vapor compression air conditioning systems because of its environmental friendliness and energy efficiency advantages. The system performance of solar desiccant cooling strongly depends on the input parameters associated with the system components, such as the solar collector, storage tank and backup heater, etc. In order to understand the implications of different design parameters on the system performance, this study has conducted a parametric analysis on the solar collector area, storage tank volume, and backup heater capacity of a solid solar desiccant cooling system for an office building in Brisbane, Australia climate. In addition, a parametric analysis on the outdoor air humidity ratio control set-point which triggers the operation of the desiccant wheel has also been investigated. The simulation results have shown that either increasing the storage tank volume or increasing solar collector area would result in both increased solar fraction (SF) and system coefficient of performance (COP), while at the same time reduce the backup heater energy consumption. However, the storage tank volume is more sensitive to the system performance than the collector area. From the economic aspect, a storage capacity of 30 m 3 /576 m 2 has the lowest life cycle cost (LCC) of $405,954 for the solar subsystem. In addition, 100 kW backup heater capacity is preferable for the satisfaction of the design regeneration heating coil hot water inlet temperature set-point with relatively low backup heater energy consumption. Moreover, an outdoor air humidity ratio control set-point of 0.008 kgWater/kgDryAir is more reasonable, as it could both guarantee the indoor design conditions and achieve low backup heater energy consumption.

“…The increasing demand for primary energy in the Kingdom of Saudi Arabia (KSA) is illustrated in Figure 3 [8]. The annual energy consumption was around 169 billion metric ton of oil equivalents in 2007, and reached 268 billion metric ton of oil equivalents in 2017 [8,9]. The comparative greenhouse gas (GHG) emissions for different countries are shown in Figure 4, which indicates the highest emission by China.…”

Wind power is the world's fastest-growing energy source. More power can be generated from wind energy through the use of new wind machine designs and techniques. The objective of the present work is to encourage people and governments to develop wind energy-based power plants to achieve sustainable energy infrastructures, especially in developing countries. In this paper, a feasibility study of a 100 MW grid-connected wind farm is conducted for five different cities of Saudi Arabia (KSA). The results indicate that the proposed power plant is feasible both technically and economically. All sites are found to be within the profitable range with Dhahran being the most feasible site among the others for the installation of the wind farm. A sensitivity analysis has also been carried out to find out the effects of different incentives on the payback period of the project.
