The Role of Phase Change Materials for Lifetime Heating of Buildings in Cold Climatic Conditions

Abstract

The study focuses on utilization of the solar insulation in buildings by means of thermal storage materials. During months of April to October, a significant part of solar gain was noticed in outer walls as well as in roof of the structure. Light weight modern construction materials have low thermal inertia so it stores less energy. The study focuses on the utilization of Phase Change Materials (PCM) for harnessing solar thermal energy for heating buildings. Various researches that show the effect of implementing PCMs in different parts of buildings like in walls, roof, windows, doors, floor etc. has been shown in the paper. The PCMs are helpful especially for those buildings which are located in cold climatic condition. Effective solutions are still required for harnessing maximum possible solar energy for heating buildings by storing heat energy by means of thermal storage materials like PCMs in hot days and to liberate it in cold night.

The influence of micro channel on the performance of low concentrator parabolic collector systems with phase change material

“…The specific heat capacity of the material, the quantity of the material, and the temperature change gradient all affect how much energy SHS systems can store. The amount of heat can be calculated by Equation (1) and Equation (2) [19]:…”

Performance Assessment of Phase Change Materials Integrated with Building Envelope for Heating Application in Cold Locations

“…Therefore, they can be applied as a heat supplier when it incorporates building envelope under cold climate conditions [58]. It has been reported that PCMs can increase the thermal storage of the building envelope, which is usually constructed from materials with low thermal inertia [59]. Seong and Lim [60] numerically studied the thermal benefits of PCMs have different melting temperatures incorporated lightweight building envelope under weather conditions of Seol, Korea.…”
