Polymeric Membrane for Dehumidification and Air Dryer System.

Hollow Fiber Membrane Dehumidification Device for Air Conditioning System

In order to provide a comfortable living and working environment indoors in tropical countries, the outdoor air often needs to be cooled and dehumidified before it enters the rooms. Membrane separation is an emerging technology for air dehumidification and it is based on the solution diffusion mechanism. Water molecules are preferentially permeating through the membranes due to its smaller kine...

Experimental study for hybrid humidification–dehumidification water desalination and air conditioning system

• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...

Air-Heating Solar Collectors for Humidification-Dehumidification Desalination Systems

Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products. However, in the context of a humidification-dehumidification (HDH) desalination cycle, air heating accounts for advantages in cycle performance. Solar collectors can be over 40% of an air-heated HDH system’s cost; thus, design optimization is crucial. Be...

Polymeric Membrane Sensor for Potentiometric Determination of Tin(II) Ions

Tin(II)-ion-selective electrode consisting of dibenzo-18-crown-6 (DB18C6) as an ionophore inPVC matrix was developed. The influences of membrane composition, selectivity, response time,reversibility and temperature on the electrode performance were investigated. The electrodeshowed a near Nernstian response for Sn2+ ions over a concentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27...
