“…There is an urgent need of incentives for the investment and the setting of taxes that reflect the total environmental cost of conventional fuels in order to overcome the constraints to the development of sun-powered cooling technology. The works of (Boopathi Raja & Shanmugam, 2012;Dickinson et al, 2010;Testi et al, 2016) highlight the costs of implementing and using this type of technologies, even making comparisons between them.…”

Context: The use of solar energy, rather than an alternative, is the viable solution to the energy demands of our planet for sustainable development. Given the population increase and the quality of life at a global scale, it is very reasonable to forecast an increase in global energy demand. In this context, solar cooling systems are a viable and timely strategy to follow. Methods: This work offers a state of the art on the different methods of obtaining solar cold. The review is generated by using the tools offered by the Scopus directory and using the VOSviewer bibliometric analysis software. Results: Solar thermal cooling in buildings is shown as a trend within these energy practices, followed by photovoltaic solar cooling. Today, the United States of America, Italy, and China are the nations that lead this field. The most fertile research areas in this subject matter are engineering, energy and materials science. Conclusions: The next few years will be decisive for the development of solar cooling technologies since they depend on the incentives and promotion plans offered by those responsible for formulating environmental and energy efficiency policies for buildings.

“…The most common pairs of working fluid in absorption chillers are lithium bromide-water (LiBr-H2O) and ammonia-water (NH3-H2O) [18]. The LiBr-H2O pair is more dominant in absorption chillers since it is cheaper, stable, free of toxins and not harmful to the environment [19]. It also has a relatively high latent heat of vaporization, less volatile than water, therefore, a rectifier is not required in the cycle [20].…”

This work investigates the performance of a single-effect absorption chiller utilizing an aqueous lithium bromide solution as the working fluid and driven by hot fluid rejected from either a geothermal power plant or the outlet of a thermal solar collector. This relatively low enthalpy return fluid, which will otherwise be reinjected back into the earth, will be utilized as the thermal energy source of the chiller. Although such chillers are considered low-grade energy refrigeration cycles, the one proposed here has an advantage in terms of economy and efficiency. A parametric analysis is performed using Engineering Equation Solver software and is used to highlight the effect of the heat exchanger size on the coefficient of performance of the chiller. The analysis proved that the proposed device can operate with excellent cooling capacity, reaching 16 kW, and a relatively high coefficient of performance (~ 0.7) while being driven by the low-grade energy. The heat source temperature, solution heat exchanger effectiveness and the size of the absorber were shown to be key parameters for the design and operation of absorption chillers. Moreover, increasing the heat source mass flow rate has a significant impact on both cooling capacity and coefficient of performance at low values (< 10 kg/s) and unnoticeable impact at higher values (> 10 kg/s).

Building energy consumption has distinctly increased in the hot-summer and cold-winter zone in China. Solar cooling technology has been developed to reduce the increasing electricity consumption for air conditioning and to shift the peak load during hot summer days. This paper presents a performance simulation and economic analysis for both photovoltaic (PV) and thermal solar cooling systems compared to a reference system, which is composed of two electric heat pumps. The results show that 30.7% and 30.2% of primary energy can be saved by using the PV and the thermal system, respectively. The payback time is 6-7 years for the PV system, but more than 20 years for the thermal system based on current conditions in China. Therefore, the PV system is more suitable for practical application in the hot-summer and cold-winter zone. The thermal system could be an alternative when middle-and high-temperature solar thermal collector technology has been further developed, as well as following mass production of small-and middle-sized chillers.
