dc.description.abstract The study investigates the performance of displacement ventilation (DV) aided by a novel evaporative cooled ceiling using Maisotsenko cycle (M-cycle). The integrated DV and evaporative cooled ceiling system is known to increase the load removal of the DV air conditioning system beyond the 40 W-m2 limit with no additional energy consumption. To increase the efficiency of the evaporative cooled ceiling, solid desiccant (SD) dehumidification system regenerated by parabolic solar concentrator thermal source is used. Predictive mathematical models of the conditioned space, the SD and the evaporative cooled ceiling are integrated to study the energy performance of the suggested combined system while utilizing an optimized control strategy for typical offices of moderate humid climate. The control strategy aims to determine optimal values of supply air flow rate and temperature and regeneration temperature while meeting space load, indoor air quality, and thermal comfort requirements. The integrated system performance is optimized to get the minimal energy cost and then compared to the cost when using a chilled ceiling displacement (CC-DV) air conditioning system.
