“…PCM are energy storage materials and must therefore be replenished/ recharged after being used. In the case of PCM boards, night ventilation is a very common method used to recharge PCM during the summer, whereby cool night air is passed through the building and absorbs the heat stored during daytime [1,2,3,4,5].…”

“…However the different ventilation charging strategies do not affect the performance. Previous studies have primarily shown that PCM systems can reduce cooling demand or temperature swing in intermittently occupied buildings [1][2][3][4][5][6]. However, as the airport schedule is less uniform and different to intermittently occupied buildings, this study shows that the PCM-HX has a higher impact on the heating demand of the space during the intermediate and summer periods.…”

“…As elaborated in various studies [1][2][3][4][5], the energy stored when the PCM is charged, has to be discharged in order to allow the appropriate and repetitive functioning of the energy storage system. The most common PCM charging method involves passing cold night air to solidify the PCM and restore its cooling potential.…”

“…The use of these materials in different forms and applications such in building wallboards and PCM plates for the thermal control of relatively small and thermally lightweight spaces have been extensively studied in the literature [1][2][3][4][5][6]. The aim has mainly been to provide additional thermal mass to lower the indoor temperature swing and prevent overheating in the space, as well as reduce the energy demand in air-conditioned spaces.…”

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). 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. The PCM-HX is also simulated in CFD, and is integrated into the overall model as a secondary coupled component in the TRNSYS interface. Different night charging strategies of the PCM-HX were investigated and compared with the conventional DV diffuser. 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.

“…Phase change materials (PCMs) are substances that have the ability to absorb and release energy at a certain temperature range [1][2][3][4][5]. Thus, they are very effective to increase the level of comfort of the building and reduce the energy consumption.…”
