Recently, due to the fact that reserves of fossil resources are depleted, it would be desirable to make maximum use of renewable energy sources to meet energy needs, including for buildings. In this study, the design and comparison of absorption refrigeration based on the sun's radiant energy has been done by thermodynamic and heat transfer methods. This study is aimed at achieving the goal of zero cooling energy building. First, a selection of related previous studies has been presented. After validating the results, a more detailed parametric analysis of similar recent studies on different types of refrigeration systems was performed, and the effective components were analyzed. Then, a dynamic and annual survey was conducted to eva‎luate the performance of refrigeration types, and finally a climatic survey including performance analysis in four cities of Iran and Iraq. In the results, it can be seen that the absorption chiller based on the sun with thermal storage has a better performance in Mosul than Tehran, and it is better in Baghdad than Mosul. The latitude of the cities also confirms the same thing in terms of the amount of radiant energy received. However, in Basra, due to more humidity, even though it has a lower position than Baghdad, we see a weaker performance than Baghdad. Also, according to the results, it can be said that the single-effect lithium bromide water absorption solar chiller produces 11.62 kilowatts in Tehran, 11.68 kilowatts in Mosul, 12.62 kilowatts in Baghdad, and 11.91 kilowatts in Basra (against fixed and certain parameters).
