“…For the study, a floor heating system with heat pipes was designed; the heat pipes heat the floor from two opposing sides in order to ensure a uniform distribution of the temperature for the floor. The interest in phase change materials in the scientific community is highlighted by the increased interest towards their applications in buildings and their integration in various building elements such as walls [9][10][11][12][13], windows [14,15], ceilings [16,17], floors [18][19][20][21][22][23].…”

The subject of buildings energy efficiency has gained increased interest in modern society. Recently, researchers aiming to reduce the energy demand of buildings have studied the implementation of phase change materials (PCMs) in various building elements. At the same time, researchers studied the implementation of unconventional technologies such as heat pipes (HP) in the buildings’ heating system. This paper combines both of these technologies in order to take advantage of the thermal storage properties of PCMs and overcome their reduced conductivity with heat pipes. Through computational fluid dynamics (CFD) simulations, this paper studies and highlights that with the implementation of a PCM, a reduction of the daily energy demand is achieved through the increase in the discharge phase time.

Usage of phase change materials’ (PCMs) latent heat has been investigated as a promising method for thermal energy storage applications. However, one of the most common disadvantages of using latent heat thermal energy storage (LHTES) is the low thermal conductivity of PCMs. This issue affects the rate of energy storage (charging/discharging) in PCMs. Many researchers have proposed different methods to cope with this problem in thermal energy storage. In this paper, a tubular heat pipe as a super heat conductor to increase the charging/discharging rate was investigated. The temperature of PCM, liquid fraction observations, and charging and discharging rates are reported. Heat pipe effectiveness was defined and used to quantify the relative performance of heat pipe-assisted PCM storage systems. Both experimental and numerical investigations were performed to determine the efficiency of the system in thermal storage enhancement. The proposed system in the charging/discharging process significantly improved the energy transfer between a water bath and the PCM in the working temperature range of 50 °C to 70 °C.

“…Pirasaci [2] applied the PCM into the exterior walls of the residential-apartment to investigate the heating and cooling process in different seasons and found that winter heating energy requirement is reduced by the PCM layer integrations. Another application of PCMs in building energy savings by using -encapsulated PCMs (Nano-PCM) and shape-stabilized PCMs is described by Wijesuriya et al [3].…”
