Abstract
Liquid desiccant air conditioning systems (LDAS) are an energy-efficient and eco-friendly
alternative to conventional air conditioning systems. The performance of a LDAS significantly
depends on its simultaneous heat and mass transfer components, namely dehumidifier and
regenerator. These components are referred to as liquid desiccant energy exchangers (LDEEs)
since the working fluids (air and desiccant) exchange both heat and moisture. There has been
a lot of research on LDEEs over the last two decades to improve their performance, thereby
enhancing the efficiency of the LDAS. The main objective of this comprehensive review paper
is to summarize the developments of LDEEs. The desiccant material, and design, operating,
and performance parameters of LDEEs are explained in detail. Even though a lot of research
has been done on LDEEs, they are not much utilized in the practical heating, ventilation, and
air conditioning (HVAC) systems. To address this issue, future research should prioritize its
focus on (i) practical problems of LDEEs such as cross contamination, and leakage and
blockage of the membrane, (ii) long term performance study in the practical systems, (iii)
noncorrosive and inexpensive solution, (iv) compatible material for efficient heat and mass
transfer, and (v) generalized design and performance control methodology. The discussions
presented in this communication will be useful to ascertain the crucial research gaps that need
to be addressed by future research studies.
