Breakthroughs in hygroscopic materials have enabled the development of innovative systems for energy-efficient building air conditioning and atmospheric water harvesting. These systems are based on the adsorption of water vapour, which allows them to remove water from the air more efficiently compared to existing solutions. This technology provides sustainable air conditioning and drinking water supply even in the driest regions of the world. In the final thesis, we analysed the performance of an energy-efficient heat pump with desiccant coated heat exchangers, which allows the simultaneous extraction of water from the atmosphere and the supply of cooled and dehumidified air to buildings. We then developed a mathematical model in the programming language Python to describe the cooling cycle of the system and calculate its efficiency.
