A novel form-stable phase-change material (PCM) based on facing bricks was developed by incorporating thermoregulating PEG-SiO2, synthetized by sol-gel method and based on polyethylene glycol as phase-change material and silica as stabilizer compound. The PEG-SiO2 in its liquid form (sol) is firstly adsorbed inside the porous brick and lastly stabilized (gel) by controlling its gelation time, obtaining form-stable PCMs with PEG-SiO2 contents within 15–110 wt.%. Kinetic adsorption curves of the sol into bricks having different porosities as well as maximum adsorption capacities were obtained. The effective diffusion coefficients (Deff) were estimated by means of Fick’s second law, it being possible to predict the adsorption of sol PEG-SiO2 by the brick as function of its porosity and the free diffusion coefficient. Finally, form-stable PCMs demonstrated an improvement in their thermal energy storage capacity (up to 338%), these materials being capable of buffering the indoor temperature during an entire operational day

The author reports an experimental investigation of the thermal performance of a multipurpose photovoltanic (PV) solar wall with phase change material (PVSW-PCM). The PVSW-PCM configuration was made of double layers. The external layer consists of a 12 Wp photovoltaic panel attached to a 15 cm thick PCM tank integrating water pipes. The internal wall is an ordinary clear glass pane. There is an 8 cm air gap between the two layers. The PVSW-PCM was integrated into the southern side of a small house of 4.05 m3 volume built by autoclaved aerated concrete block walls 0.07 m thick. On top of the external layer, three glass blocks (3 × 0.2 × 0.2 cm2) are installed to ensure indoor illumination. The absorbed solar radiation by the PV panel and PCM heats the water in the pipes and the air in the gap. The hot water produced is stored in a 10 liters tank located near the roof. At the inner lower part (room side) and the external upper part (ambient) of the gap, a small DC fan (12 V, 0.48 A) box was installed. The fans were connected to the PV panel directly to enhance indoor ventilation. The investigation considered both natural (fans OFF) and PV assisted ventilation. Another similar house without the PVSW-PCM referred to as glass wall (GW) was built and used as a reference for comparison. The experimental results revealed that the indoor temperature of the PVSW-PCM house was considerably lower than that of the GW house. Moreover, the PVSW-PCM could produce hot water temperature of 55–62 °C and induce a ventilation rate proportional to the intensity of solar radiation. Indoor illumination was sufficient for general house use. Therefore, the PVSW-PCM offers a new alternative for architects and engineers to reduce electric energy use for producing hot water and ventilation and save electrical energy consumption of air conditioner, as the indoor temperature is lower than that of the conventional house.

Since energy storage with phase change materials is an effective means of energy saving or conservation in buildings, its investigation and applications have received more and more during the recent years. The research actuality on energy saving of adjustment and control of building indoor temperature was summarized in this paper, and the two types of the major techniques with phase change material applied in adjustment and control of building indoor temperature was reviewed, in which one is the technique combined phase change material with building maintenance structure, the other is the technique to make phase change material applied to heating or air conditioning systems. The future research of phase change energy storage in adjustment and control of building indoor temperature was prospected.

Experimental study was conducted on the thermal performance and energy saving effect of a room with shape-stabilized phase change material (PCM). The results showed that the mean indoor temperature of the room with PCM floor was about 2°C higher than that of the room with normal floor and the indoor temperature swing range narrowed greatly. The results also manifested that by applying shape-stabilized PCM in room suitably, the thermal comfort level could be raised and space heating energy in winter could be saved. Finally, the experimental results enriched the database for the further modeling and simulation research.

Change Material

The novel shape-stabilized phase change material (PCM) has the following salient features: large apparent specific heat for the phase change temperature region, suitable thermal conductivity, and the ability to keep the shape stabilized when it undergoes a phase change. In this technical brief, we put forward a kind of shape-stabilized PCM floor that is able to absorb solar radiation energy in the daytime and to release the heat at night in winter. The thermal performance of a prototype room using such a floor was studied. The experiments show that the mean indoor temperature of a room with the PCM floor is about 2°C higher than that of the room without a PCM floor, and the indoor temperature swing range is obviously minimized. Therefore, installing shape-stabilized PCM in a room may increase the degree of thermal comfort and reduce space heating energy consumption in winter. In addition, the experimental results provide data for modeling and simulation research for such PCM floor systems.
