**1. Introduction**

The world's main development is the energy because the technological advances and economic growth in countries rely on it. The energy demand is basically affected by three major factors, namely, population, economy, and the per capita energy consumption. The increase in energy demand leads to increased greenhouse gas emissions associated with the burning of fossil fuels and contributes to global warming. The energy demand associated with air-conditioning in most industrialized countries has been increasing in recent years. Traditional mechanical steam compression systems have been used for decades; nevertheless, it demands large amounts of electrical energy for the operation of the compressor; this energy demand not only affects the environment but also negatively impacts the user in economic terms associated with the cost of operation. Therefore, it has become crucial to design air-conditioning systems that are respectful to the environment and are capable of operating using waste or renewable energy sources. Commercially available absorption chillers for air-conditioning applications usually operate with LiBr/H2 O mixture and use steam or hot water as the heat source [1]. It has been testified that single-effect LiBr/H<sup>2</sup> O absorption units using fossil fuels are not competitive from the energy, economic, and environmental points of view. They are only competitive when using waste or renewable heat as part of the driving energy [2]. Besides, according to the operating temperature range of driving thermal source, single-effect LiBr/H<sup>2</sup> O absorption chillers have the advantage of being powered by ordinary flat-plate or evacuated tubular solar collectors. The main advantages of solar absorption cooling systems concern the reduction of peak loads for electricity utilities, the use of zero ozone depletion impact refrigerants, the reduction of primary energy consumption, and the reduction of global warming impact [3, 4]. Cold production through absorption cycles has been considered one of the most desirable applications for solar thermal energy.
