Abstract
In this study, ventilation performance of liquid desiccant in an evaporative-cooling assisted 100% outdoor air system was evaluated. Carbon-dioxide gas was used as a tracer gas to evaluate the ventilation performance. Air change rate (ACR) was considered as a ventilation efficiency index. CO₂ gas was injected in to test room of 81 m³ and concentration decay was measured when ventilating room with LD-IDECOAS and VAV system. Supply air flow rate of two system is set to 1500 CMH and 1200 CMH of return air was used in VAV system. Conquently, it was found that the LD-IDECOAS has better ventilation performance than VAV system.
