A technical review on regeneration of liquid desiccant using solar energy

In a global era, continuous increment in energy requisition with its associated cost and relevant climate problems is causing accentuation in exploring more efficient ways to provide air conditioning in enclosed space without degradation of the environment. In the hot and humid area, major part of conventionally produced electrical energy is consumed by air conditioning. Also in the rapidly growing world scarcity of clean water is dilemma as equal as green-house and ozone layer depletion. Thus, there is emergence of dehumidified air for human comfort conditions with having potable clean water same time. In summer with largely available solar radiation, use of hybrid solar system is viable option to overcome problems of dehumidification of liquid desiccant as well as of potable water. Up till now the conventional dehumidification with desiccant solution has been improved or replaced by less costly new systems. This paper provides an extensive literature review on development of liquid desiccant regeneration using solar energy. The paper also includes the recent findings of hybrid solar system in which either two sources of heat is used for regeneration of liquid desiccant or solar energy is used for regeneration of liquid desiccant along with other application.
