Solar Heating

Healthcare-associated infections cause a massive burden for the health care system and the patients. Although the standard sterilization protocol with saturated steam (>121°C and >205 kPa) is effective, generating high-temperature and high-pressure steam is challenging without reliable access to electricity or fuel. While abundant solar energy is readily available, utilizing sunlight to generate steam beyond 100°C requires costly and bulky optomechanical components. In this work, we developed a stationary solar thermal device capable of providing the required saturated steam.
This paper presents a review of exergy analysis of solar thermal systems. It includes both various types of solar collectors and various applications of solar thermal systems. As solar collectors are an important technology when sustainability is considered, exergy analysis, which gives a more representative performance evaluation, is a valuable method to evaluate and compare possible configurations of these systems. It should be noted that this review is based on literature published in the last two years.
