Evaporative cooling is a clean and energy-efficient cooling technology that relies on the water’s latent heat of vaporization to cool the air. It has a long historical record for cooling applications before modern vapor-compression air conditioning was invented. Despite its history, there has not been a revolutionary change on evaporative cooling until the past century, where multiple designs of evaporative coolers were developed, tested and adopted. This chapter presents several key evaporative cooling technologies that have evolved, including direct, indirect, and dew-point evaporative cooling. Direct and conventional indirect evaporative cooling experience thermodynamic limits based on the air’s wet-bulb temperature, and hence have confined applications. To address this issue, an innovative indirect evaporative cooling, termed the dew-point evaporative cooling, has been proposed. Its unique feature of pre-cooling the air enables it to cool the air towards dew-point temperatures.
