Executive Summary : | Waste heat energy recovery from building needs lot of attention and focus to minimise energy consumption. The role of degradable material is inevitable in energy recovery process as it improves the self-sustainability of environment. Indian Metrological Department (IMD) reported that the annual mean temperature rise of 0.99 degree for the last 100 years causes higher heat load on buildings and leads to human discomfort and health issues. About 20-25% of energy consumption occurs due to space cooling based on the report given by International Energy Agency (IEA) 2018. Cooling demands are increasing, also conventional cooling is energy intensive and environmentally damaging refrigerants are employed. In order to ensure the pro- environmental materials on the building cooling application, Phase Change Materials (PCMs) are introduced. There are several methodologies in existence to prevent heat load and one such methodology is introduction of (PCMs) in buildings, PCM material used as additional layer in both roof as well as side walls. This additional layer on the walls and roofs are fixed through panels and Compact Storage Modules (CSMs). The effective cooling is achieved in buildings through charging, discharging of PCMs from sunshine and sun set. Several recent works reported either theoretical or experimental temperature profile of the building using PCMs, very few only discussed energy savings point of view. This investigation focuses both organic PCMs and bio-based PCMs on energy savings with respect to temperature difference attained by the building. Previous investigations also revealed the need of PCM in the buildings but very few researchers have worked on Macro encapsulated organic PCMs and bio-based PCMs. which can create environment friendly material for future. In this project, it is proposed to replace the conventional types with novel envelopes, CSMs as macro encapsulation technique. Also it ensures the higher thermal cycling rate with optimum induction of PCMs. |
