Study of solar regenerated membrane desiccant system to control humidity and decrease energy consumption in office spaces

The validated model was applied to a case study consisting of an internal office during the month of August in Beirut hot humid climate. A decrease of 10% in indoor relative humidity is observed when the system was used. The cost of the proposed system was compared to the cost of a conventional vapor compression cycle that provides the same indoor conditions. A payback period of 7 years and 8 month was estimated compared to the investment in the vapor compression cycle.
