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 sp. Increased population, improved economy, comparatively lower cost of air conditioning. As early in history of solar operated LD air conditioning, Lof reported the use of LD TEG in dehumidification followed by evaporative cooling system as shown in Fig. 3. An auxiliar. In last few decades, a Hybrid solar system concept is getting more popular and popular due to its ability to achieve more required condition of air rather than LDAC alone. In the hybr. In the present paper, authors have attempted to include a detailed literature survey on regeneration of LD with the help of solar energy. Authors have also discussed the co. 1.Kodama A. An energy flow analysis of a solar desiccant cooling equipped with a honeycomb adsorber. Springer Science+Business Media Inc. Manufactured in.

Can solar heat be used for regenerating a desiccant wheel?
Substantial energy savings can be achieved by use of renewable solar heat for regenerating the desiccant wheel used in the hybrid cooling system. Thermodynamic performance of the solar powered desiccant based comfort cooling system was evaluated by Koronaki et al. .
Does a hybrid desiccant air-conditioning system reactivate solar energy?
Kabeel experimentally evaluated the performance of a hybrid desiccant air-conditioning system integrated with a rotary honeycomb wheel that utilized renewable solar energy for the reactivation, at various conditions of inlet air and different radiation intensity of solar heat.
How to dehumidify process air?
Dehumidifying the process air was done using liquid desiccant solution of calcium chloride (CaCl 2) concentration 40% by mass. After the dehumidifying process air, solar energy is used to reactivate diluted and continuously operate the system cyclically.
Does a solar powered solid desiccant based hybrid cooling system improve performance?
The ameliorated performance of the solar powered solid desiccant based hybrid cooling system indicates its superiority relative to other heat-driven devices for solar based air conditioning systems, , , , , .
Does room specific humidity affect dehumidification of process air?
The authors have concluded that dehumidification of process air and regeneration of liquid desiccant reduces as room temperature increases and increases with increase in room specific humidity. Fig. 33. Block diagram of hybrid solar system .
What is solar powered desiccant based hybrid air-conditioning system?
In the solar powered desiccant based hybrid air-conditioning system, the latent load is handled effectively by the rotary desiccant dehumidifier while the sensible load is mainly taken by the sensible cooling coil of evaporator in conventional vapor compression system. So, the electricity consumption of the VCR evaporators can be greatly reduced.
