- Abstract
- The purpose of this study is to evaluate the primary energy saving potential of an organic Rankine cycle integrated with a liquid desiccant and evaporative cooling-assisted ventilation system in a residential building. In cases where non vapor-compression-based systems are used, a evaporative cooler can lower the temperature of processed air using the latent heat of vaporization of water, while a liquid desiccant system can enhance the cooling effect of the evaporative cooler and dehumidify the processed air. This system can operate each component independently according to outdoor air conditions and can provide sensible cooling while meeting the ventilation requirements of the space considered. The organic Rankine cycle driven by a district heat source is applied to the ventilation system, and the heat and power generated are assumed to be used for the operation of the system. A simulation study was conducted during the cooling season that showed an adequate performance for the cooling system. The primary energy consumption of the proposed system was compared to the same ventilation system that was powered by a conventional grid power system and a boiler.
