Abstract
The use of PCM for thermal energy storage (TES) is part of the research activities carried out by ENEA for solar heating and cooling (SH&C) systems optimization. The test facility is a SH&C system located at ENEA (Rome) and it achieves winter and summer air-conditioning of F-92 building. According to the first experimental analysis of SH&C facility (year 2012), during winter period, it resulted necessary a TES with a capacity bigger than the first tank installed because there were both wasting of energy produced by solar field and the working of integration system. So to better exploit solar energy and therefore to maximize the rate of thermal energy stored in TES, in March 2013 the standard tank (1500 liters), initially present, was replaced with a PCM tank (1000 liters). According to a previous analysis, the solution that optimizes energy and economic SH&C system performance is a latent TES designed to accumulate energy at a temperature of 45 °C (operative temperature during winter). The PCM selected consists of hydrated salts. The effect of PCM TES installation is studied and presented here also by the comparison between results of 2012 and 2013 experimental campaignI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
