Performance Analysis of Air Gap Membrane Distillation Process Enhanced with Air Injection for Water Desalination.

Water scarcity is a global issue, and desalination is an alternative to providing fresh water. Renewable energies could be used in thermal desalination to produce freshwater from high saline concentration solutions. In this paper, the experimental performance of an air-injection-Air Gap Membrane Distillation (AGMD) module is presented.

Experimental Performance of a Membrane Desorber with a HO/LiCl Mixture for Absorption Chiller Applications.

For absorption cooling cycles using water as a refrigerant, HO/LiCl mixtures are suitable for replacing conventional HO/LiBr mixtures. In addition, membrane devices can be used to develop compact and lighter absorption systems, and they can operate with HO/LiCl mixtures. The present paper describes an experimental evaluation of a membrane desorber/condenser operating at atmospheric pressure.

Experimental Performance of a Membrane Desorber Operating under Simulated Warm Weather Condensation Temperatures.

In absorption systems using the aqueous lithium bromide mixture, the Coefficient of Performance is affected by the desorber. The main function of this component is to separate the refrigerant fluid from the working mixture. In conventional boiling desorbers, constant heat flux and vacuum pressure conditions are necessary to carry out the desorption process, and usually, the absorbers are heavy and bulky; thus, they are not suitable in compact systems.

Role of Membrane Technology in Absorption Heat Pumps: A Comprehensive Review.

The role of heat pumps is linked to the actions of human life. Even though the existing technologies perform well in general, they have still some problems, such as cost, installation area, components size, number of components, noise, etc. To address these issues, membrane technologies have been introduced in both heat and cooling devices.
