Patent 11035581 was granted and assigned to Kuwait Institute for Scientific Research on June, 2021 by the United States Patent and Trademark Office.
The integrated desalination and air conditioning system can provide desalinated (fresh) water, cold air or both in a single efficient system. The system incorporates a humidification-dehumidification (HdH) desalination system with a water-lithium bromide (H2O—LiBr) vapor absorption cycle (AbC) system. The AbC system includes an AbC generator that provides a heating source for an AbC condenser that heats the air input of the HdH; two AbC absorbers that provide heating sources for the feed seawater; a first AbC evaporator that provides a cooling source for the humidified air produced in the HdH; and a second AbC evaporator that provides a cooling source for use outside the system. The heat input for the AbC generator can be provided by low-grade heat sources, such as waste heat or solar thermal energy. The system is capable of producing fresh water and/or cold air at different capacities, depending on water demands and cooling load requirements.
