Experimental evaluation of commercial heat exchangers for use as PCM thermal storage systems
TL;DR: In this paper, the heat transfer process during melting (charge) and solidification (discharge) of five small heat exchangers working as latent heat thermal storage systems was investigated experimentally, and the results showed that the double pipe heat exchanger with the PCM embedded in a graphite matrix (DPHX-PCM matrix) is the one with higher values, in the range of 700-800 W/m 2 -K, which are one order of magnitude higher than the ones presented by the second best.

Thermal performance of a greenhouse with a phase change material north wall
TL;DR: In this paper, the thermal performance of a north wall made with phase change material (PCM) as a storage medium in an east-west oriented greenhouse is analyzed and discussed, and a numerical thermal model taken into account the different components of the greenhouse (cover, plants, inside air and north wall PCM) is developed to investigate the impact of the PCM on greenhouse temperature and humidity.

Experimental study and evaluation of latent heat storage in phase change materials wallboards
TL;DR: In this article, a phase change materials (PCM) wallboard room was constructed by attaching PCM wallboards, developed by incorporating about 26% PCM by weight into gypsum wallboard, to the surface of an ordinary wall.
