Water scarcity is a pressing global issue driving the need for efficient and sustainable water reuse desalination technologies. In last two decades, humidification–dehumidification (HDH) has emerged as promising method small-scale decentralized systems. This paper presents comprehensive review of recent scientific literature highlighting key advancements, challenges, potential future directions...

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...

In the current context of joint efforts towards decarbonisation buildings, integrating occupants’ comfort and health with latest technological advancements for energy efficiency is at center development research, policies professional practice. Radiant systems are encountering great success since low-thickness can also be used in renovation projects both heating cooling, while guaranteeing opti...

In a 10-ton capacity pilot plant solar liquid desiccant air conditioner (LDAC) developed, dehumidification of the outside air is achieved through a honeycomb packed-bed heat and mass exchanger, using lithium chloride solution as the desiccant. The dry air obtained from the dehumidification process is evaporative cooled inside a cooling pad and directed into the conditioned space. The dilute sol...

Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...
