Abstract

The chapter presents the recent studies focusing on optimizing the efficiency of air-conditioning (AC) systems using solar energy. For this purpose, several advanced AC plants (absorption, adsorption, and desiccant) are designed. Their technology and components are described in this chapter. It also discusses the energy intake of the solar energy use in air-conditioning, especially in rural regions where the electricity shortage is frequent, as well as the reduction of the energy costs and the pollution rate. A comparison between solar AC systems and traditional AC systems at the level of the designs, costs, and effectiveness is made at the end of the chapter.

Highlights

  • In recent years, the demand for comfort has been accentuated due to the earth’s changing climate

  • The solar AC systems reported in this chapter present an interesting worldwide solution to reduce the harmful effects of traditional AC systems

  • Research studies revealed that absorption, adsorption, and desiccant systems allowed saving energy up to 80, 50, and 52%, respectively, thanks to the optimization of their designs at the level of using environmentally unfriendly refrigerants, investing in the free and clean solar energy to power them, as well as at the level of the choice of the components that comprise them

Summary

Introduction

The demand for comfort has been accentuated due to the earth’s changing climate. The use of air-conditioning systems is increased, which leads to higher costs and consumption of energy. An increasing interest has been concentrated on the design of modern sustainable AC systems powered by renewables, especially the solar energy that is a universally inexhaustible natural and clean resource [1]. It can offer a reduction of the consumption, the demand, and the costs of energy, without decreasing the desired comfort. These systems allow converting the solar thermal energy
