Comparison simulation between ventilation and recirculation of solar desiccant cooling system by TRNSYS in hot and humid area

摘要: Two modeling of solar desiccant cooling system in different modes of ventilation and recirculation were designed based on hot and humid weather of Malaysia. The latent load and sensible load of the test room were 12283.71 BTU/hr, 37533.56 BTU/hr respectively. The mass flow rates of process air and regeneration air were 0.86 kg/s. The effectiveness of components is selected based on high efficent system because the main objective of this study is comparison between ventilation and recirculation modes. By investigation of simulation results of ventilation and recirculation modes, it was found that, amount of ventilation and recirculation COP were 0.8, and 1.6 respectively. Therefore it was achieved that the recirculation solar desiccant cooling system in hot and humid area is higher efficent than the ventilation solar desiccant cooling system.
