Experimental Study on Two PCM Macro-Encapsulation Designs in a Thermal Energy Storage Tank

an experimental study of energy charging and discharging in a pcm thermal storage

in this work, a thermal energy storage system was designed and equipped with measuring instruments to study heat transfer characteristics and energy storage and release. in this system, a cubic container which is made of plexiglass was filled with dodecanoic acid as a phase change material. in order to transfer heat to the storage container, a constant temperature heat exchanger was designed an...

Development of Hollow Steel Ball Macro-Encapsulated PCM for Thermal Energy Storage Concrete

The application of thermal energy storage with phase change materials (PCMs) for energy efficiency of buildings grew rapidly in the last few years. In this research, octadecane paraffin was served as a PCM, and a structural concrete with the function of indoor temperature control was developed by using a macro-encapsulated PCM hollow steel ball (HSB). The macro-encapsulated PCM-HSB was prepared...

Energy efficiency in a building complex through seasonal storage of thermal energy in a confined aquifer

Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
