In this work, melt blending method was used to prepare two composite phase change materials of myristic acid-stearic acid (MS) and myristic acid-stearic acid-lauric acid (MSL). The optimum mass ratios of MS and MSL were 77 : 23 and 28 : 9 : 63 by step cooling curve assay, respectively. The phase transition temperature of MS and MSL were 47.13 °C and 28.81 °C by differential scanning calorimetry (DSC), and the latent heat of phase transition of MS and MSL were also measured to be 153.3 J/g and 143.3 J/g, respectively. On the other hand, the phase transition temperature of MSL had little change after 300 cycles, indicating that it had good stability. In addition, the structure characteristics of MSL was found to be the same as that of pure material by FTIR, which indicates that materials are interacted by molecular force. Therefore, MSL can be used in construction and has a good application prospect.

“…Furthermore, the porous properties of the carrier increase the surface area of the composite adsorbent-these materials enhance the heat and mass transfer efficiency with increasing surface area [33]. Commonly used porous matrix (CSPM) include silica gel [34,35], zeolite [36,37] and expanded graphite [38]. Zeolites are porous materials with good water absorption capacity and the ability to function at high temperatures, thus forming excellent matrices for composite materials [39].…”

Adsorption-based thermochemical heat storage is a promising long-term energy storage technology that can be used for seasonal space heating, which has received significant amount of efforts on the research and development. In this paper, the heat storage capacity of composite adsorbents made by LiCl + LiBr salt and 3A zeolite was investigated. The basic characteristics of composite material groups were experimentally tested, and it was found that the adsorption composite with 15 wt% salt solution had excellent adsorption rate and adsorption capacity, which was considered as the optimal composite material. Furthermore, the heat storage density of the composite material could be as high as 585.3 J/g, which was 30.9% higher than that of pure zeolite. Using 3 kg of the composite material, the adsorption heat storage experiment was carried out using a lab-scale reactor. The effects of air velocity and relative humidity on the adsorption performance were investigated. It was found that a flow rate of 15 m3/h and a relative humidity of 70% led to the most released adsorption heat from the composite material, and 74.3% of energy discharge efficiency. Furthermore, an adsorption heat storage system and a residential model were built in the TRNSYS software to evaluate the building heating effect of such heat storage system. It is found that the ambient temperature will affect the heating effect of the adsorption heat storage system. The coefficient of performance (COP) of this model is as high as 6.67. Compared with the gas boiler heating system, the adsorption heat storage energy can replace part of the gas consumption to achieve energy savings.
