The results show that: i) the displacement ventilation system is more efficient for cooling than heating a space ii) the addition of a PCM-HX system reduces the heating energy requirements during the intermediate and summer periods for specific night charging strategies, whereas winter heating energy remains unaffected iii) the PCM-HX reduces cooling energy requirements, and iv) maximum energy savings of 34% are possible with the deployment of PCM-HX retrofitted DV diffuser.

Different night charging strategies of the PCM-HX were investigated and compared with the conventional DV diffuser. Mastering Ansys CFD (Level 1) Become pro in computational fluid dynamics (CFD) from A to Z using Fluent, CFX, ICEMCFD and Ansys Workbench. The PCM-HX is also simulated in CFD, and is integrated into the overall model as a secondary coupled component in the TRNSYS interface. Simulations Evaluating game system behavior Petri Lankoski Södertörn Univeristy 2. A TRNSYS-CFD quasi-dynamic coupled simulation method was employed for the analysis, whereby TRNSYS ® simulates the HVAC and PID control system and ANSYS FLUENT ® is used to simulate the airflow inside the airport terminal space. Capable of performing dynamic thermal simulation for the world’s largest and most complex buildings, Tas allows designers to accurately predict energy consumption, CO2 emissions, operating costs and occupant comfort. Tas is an industry-leading building modelling and simulation tool. This paper reports on the energy performance evaluation of a displacement ventilation (DV) system in an airport departure hall, with a conventional DV diffuser and a diffuser retrofitted with a phase change material storage heat exchanger (PCM-HX).
