Energy-saving potential of a passive cooling system for thermal energy management of a residential building in Jaipur City, India

A major percentage of the energy is utilised for the building sectors for cooling the building which is used for Airconditioning systems. One of the techniques for decreasing energy consumption in building systems is passive cooling. The PCM materials was integrated in the building which is isothermal temperature for storing and retrieving the energy during a phase change. The stored PCM is a constant temperature for phase change and also gives the large potential of energy during the storing and releasing energy. The integrated building wall to prevent the solar heat infiltration into buildings and controlling the indoor temperature swing. The selection and efficiency of PCMs are highly subjective to climatic conditions where they applied. In the present study, a real time PCM integrated residential building is studied through numerical simulation using Design Builder software in moderate climatic condition in Bangalore city, India. The result shows that throughout the year, the PCM room does not required any air-conditioning device for cooling application.

Nowadays the energy usage in the building sectors in the construction industry has been increased for increasing the cooling and heating loads of buildings. The renewable energy generation and incorporation of PCMs in building sectors attains around the world for energy savings. A passive cooling method with PCM integration in the building system is to decrease the energy demand of buildings. This process involves storing cool and heat energy and discharging it as needed. In this work, the ENERGYPLUS simulation has been carried for the PCMs incorporated in the constructed building wall in hot climatic weather conditions in India for considering the passive cooling method. It reduce the daily indoor temperature variation in PCM building throughout the year through absorption of cool energy in PCM during early morning hours without using mechanical energy devices.

“…The energy consumption of the PCM structure is lower in tropical and snowy climes. Zhou et al [7] and Arun Prakash et al [8] examined the thermal PCM's performance in buildings, taking into account the PCM layer and the time lag. The PCM layer thickness has less of an impact on the decrement factor during the warmer months, lowering the PCM room temperature and maintaining comfortable conditions.…”

Incorporating PCM in building envelopes is a promising energy-saving technique. Because the PCM container maintains a constant temperature when storing and retrieving energy. The PCM is used in building envelopes to diminish solar irradiation, reducing heat penetration and lowering heating and cooling loads. It’s vital to get the right PCM for different climates. Because the ambient air temperature fluctuated a lot throughout the year. PCM temperature effectiveness is highly determined by local ambient weather conditions. It is challenging to design the PCM integrated building for year-round thermal regulation. This research discussing PCM’s thermal energy effectiveness in building walls for decreasing interior temperature variance in composite climatic systems using numerical simulation using EnergyPlus software.
