Modeling of a LiBr-H2O absorption air conditioner system driven by a solar flat plate collector

In regions with hot and mixed climates, the principal energyusers in buildings are the systems that provide cooling and air-conditioning.Buildings consume more energy as a result of their reliance on traditionalelectrically powered systems. Solar energy has emerged as an importantalternative for many uses, including cooling and air-conditioning. In thispaper, to simulate a solar-assisted single-stage LiBr-H2O absorption airconditioner system, a mathematical model is presented. The model maysimulate either the static or the quasi-static state of the system. The model isconstructed using mass and energy balances that are applied to the variouscomponents found on the inside of the machine. The experimental data thatwere acquired for one of the other works in the body of literature are used tovalidate the model that was developed. In this study, the quantity of energygiven by a flat plate solar collector to cool the air in a room in Meknès cityon a typical summer day is compared to the cooling load imposed by acooling fan in the same room. The simulation shows that a flat plate solarcollector to power our system can only be used effectively under specificsolar irradiance conditions.
