Review of Phase Change Materials Integrated in Building Walls for Energy Saving

Procedia Engineering (2015)

Yaping Cui Jingchao Xie Jiaping Liu Song Pan

Thermal energy storage systems (TES), using phase change material (PCM) in building walls, has become a hot topic within the research community in recent years. As more and more articles have been published, it is essential to review previous work so as to have a good knowledge of PCM walls in energy saving. Several aspects are discussed in this review, including the PCM thermo-physical properties, PCM types, PCM incorporation methods suitable for PCM walls, and specific application methods of PCM walls. Although it is known theoretically that PCM walls have a relatively good potential for energy saving, more researches focusing on real full-scale buildings and real operation conditions should be done to prove the authenticity and reliability of current study.

A review on phase change material application in building

Advances in Mechanical Engineering (2017)

Yaping Cui Jingchao Xie Jiaping Liu Jianping Wang Shuqin Chen

In the past several decades, many literatures have emerged on the topic of phase change material and latent heat storage techniques used in building. Accordingly, it is essential to review previous work to know about phase change material application in building better. This article presents a review on phase change material application situations in building, and several aspects are discussed: phase change material major applications in building, phase change material application areas, phase change material application types, phase change material thermal–physical properties, and phase change material application effects. The results of this research show that phase change material application areas are mainly concentrated into four parts of north latitude from 25° to 60° and south latitude from 25° to 40°. No matter in which region, the use of paraffin is the broadest (the maximum use frequency is up to 87.5%). For organic phase change material, the melting temperature and the heat of fusion vary from 19°C to 29°C and from 120 kJ/kg to 280 kJ/kg, respectively. The best phase change material application effect found is a reduction of 4.2°C for air temperature in room. This study has important and directive significance for the practical application of phase change material in building.

A Performance Assessment Method for Main HVAC Equipment with Electricity Submetering Data

Procedia Engineering (2017)

Ying Ji Peng Xu Jingchao Xie

HVAC system is one of the biggest contributors to building energy use, and meanwhile a considerable part of energy is wasted due to the faulty operation of it. Hence, detecting and diagnosing HVAC system faults and improving energy efficiency are of large economic and environmental impact worldwide. However, the current study or application is highly limited by the scarcity of energy usage data, while in recent years electricity submeter was widely implemented and massive amounts of submetering data were accumulated in China. The aim of this paper is therefore to develop a performance assessment framework which is specifically designed for HVAC systems in such commercial buildings with electricity submetering data. This framework consists of three parts. 1) A HVAC terminal energy usage disaggregation algorithm and 2) a cooling load estimation algorithm are firstly performed to make up data deficiency. And then, 3) a diagnosis algorithm is proposed, which uses EPI generated from a Chinese standard (GB/T 17981-2007) as the benchmarks. Finally, a real case study in Shanghai is presented to illustrate the proposed framework and shows that the building operators can easily identify the poor performance area.

Experimental Study on Capillary Water Absorption Performance of Coral Sand Concrete in High-Salt Environment

Journal of Materials in Civil Engineering (2024)

Zhimiao Zheng Jingchao Xie Xin Xu Yue Xie Jiaping Liu

The high-salt fog environment under a marine climate affects the capillary water absorption performance of porous building materials, causing changes in the thermal and wet properties of the materials and in their structural durability. Therefore, a capillary water absorption experiment of coral sand concrete (CSC) in different salt solution concentrations was designed in this study. The experimental results showed that salt had the effect of first promoting and then inhibiting capillary water absorption coefficient (Acap) with increased salt solution concentration. Salt had the effect of promoting liquid diffusivity (Dl). In addition, by analyzing the surface tension and viscosity of a sodium chloride solution, the mechanism of the influence of liquid properties on Acap was briefly explored. The results provide a theoretical basis for the establishment of a coupled heat and moisture transfer model of porous building materials in marine climates.
