Thermal energy storage systems have become most essential in case of solar thermal applications in order to supply the energy during cloudy and off sunshine hours. In this study, the thermal energy storage and recovery capacity of solid desiccant consisting of 60% bentonite, 10% calcium chloride, 20% vermiculite and 10% cement on dry weight basis combined with paraffin wax latent heat storage medium are studied. The ratios for volume percentage of solid desiccant and paraffin are 90: 10, 80: 20 and 70: 30. The paraffin wax with melting point of about 61.6°C and latent heat of fusion 253 kJ/kg is filled inside the hollow cylindrical solid desiccant mould. An experiment is conducted at air mass flow rate of 0.01, 0.02, and 0.03 kg/m2s with temperatures of 40, 50 and 60°C. The heat storage and retrieval capacity of 80% solid desiccant with 20% paraffin wax at 50°C and 0.02kg/m2s show the better results which are suitable for solar drying. © Research India Publications.

An indirect type forced convection solar dryer integrated with solid desiccant and phase change material has been designed, fabricated and tested. The major components are flat plate collector, blower, and an integrated thermal storage drying chamber. The dryer was constructed using locally available materials. Drying experiments were performed for Turmeric (Curcuma longa) with initial moisture content of 87 %(wb) with forced convection mode and with the integration of desiccant unit combined with phase change materials(PCM) at different mass flow rates of air. The drying time takes about 43 hours to reach equilibrium moisture content of 8% (wb) in the case of desiccant integrated solar drying and about 57 hours without the integration of desiccant unit. The inclusion of paraffin wax with the solid desiccant advances the drying process by 7 hours. © Research India Publications.

This paper proposes smart energy efficient lighting system based on intelligent controller and sensors. This present project target at designing and executing the advanced development systems for energy saving of street lights with light depending resistor (LDR). This project is designed to detect vehicle movement on street ways to switch ON only a block of street lights ahead of it (vehicle), and to switch OFF the tracking lights to save energy. This project gives the best vital for electrical power distribution. This is achieved by sensing an impending vehicle and then switches ON a block of street lights ahead of the vehicle. Further the project can be assisted by using appropriate sensors for detecting the failed street light and then sending an Sending Message Service (SMS) to the control department via Global System For mobile Communication (GSM) modem for appropriate action. This present systems are once implemented on a large scale can bring powerful reduction of the power consumption caused by street lights. This firm will help the government to save this energy and meet the domestic and industrial needs. © Research India Publications.
