On a novel integration of a multistage absorption heat pump with a balanced humidification-dehumidification desalination unit
This study investigates a novel cooling-desalination system having a single-double-effect absorption heat pump coupled with a humidification-dehumidification desalination unit. A waste-heat source drives the system in addition to natural gas. Using a waste-heat source lowers the cost of the desalina...

This study investigates a novel cooling-desalination system having a single-double-effect absorption heat pump coupled with a humidification-dehumidification desalination unit.

Using a waste-heat source lowers the cost of the desalinated water and thus gives the proposed system considerable attention in the water market. The results reveal that the system can produce desalinated water of about 110 l per day for 0.0068 $/l with a gained output ratio of 4.15.
