ABSTRACT
This chapter reviews analysis and design strategies for solar-assisted air conditioning systems in hot and humid climates. The general strategy consists of presenting three different options. They include an absorption unit coupled with an array of flat-plate collectors, an absorption unit coupled with an array of flat-plate collectors and a liquid desiccant system, and an absorption unit coupled with an array of flat-plate collectors and a solid desiccant system. The chapter provides a brief historical background on the development of solar-assisted air conditioning and dehumidification technologies. It summarizes the operation of closed absorption machines and liquid and solid desiccants, when coupled with arrays of solar collectors. The desirable properties for the refrigerant are high heat of vaporization, low specific heat capacity, and good thermal stability, while for the absorbent, chemical stability, high boiling point, and low heat capacity are advantageous.
