This paper summary the investigation and analysis of thermal energy storage extracted from solar heater and use for domestic purpose. Choosing a suitable phase change materials honey wax used for storing thermal energy in insulation tank. The tank carries minimum of 45 liters capacity of water and 50 numbers copper tubes each copper tube carries minimum of 100 grams PCM materials. Inside the tank phase change materials are receiving hot water from solar panel. This solar energy is stored in Copper tubes each copper tube contains PCM Materials as latent heat energy. Latent heat is absorbed and stored in Copper tubes. Large quantity of solar energy can be stored in a day time and same heat can be retrieved for later use. The tank was instrumented to measure inlet and outlet water temperature. The differences of temperature of the water is measured in a definite interval of time have been noted then calculating heat transfer rate and system effectiveness. The heat storage system is to be applied to store solar energy and the stored heat is used for domestic hot water supply system.Keywords

Heat energy is the vital source of energy being utilized in various fields. If a compact thermal storage device, which permit storage of heat and retrieval of heat, it will become more suitable for many process industries as well as domestic applications. In this present work, the heat carrying capacity of the domestic water heater (Geyser) is improved with the help of PCM capsules. Melting and solidification of phase change materials (PCM) in a capsule is of practical importance in latent heat thermal energy storage (LHTES) system which are considered to be very promising to reduce a peak demand of electricity. Here heat energy is stored in domestic geyser with encapsulated PCM, it has been planted inside the geyser. The encapsulated PCM balls used as energy conserving or storing unit. Heat energy is to be stored in the geyser by providing phase changing materials as latent heat thermal storage, when power supply is given to geyser then water is heated by heating rod up to a temperature range of 55°C to 60°C at the same time heat is transferred to number of encapsulated PCM balls inside the geyser. Since large amount of heat is stored in that PCM material. This stored energy can be retried by pouring water for next usage of hot water without giving heat supply again. Modified geyser is different from the conventional geyser PCM encapsulated are used inside it to increase the efficiency of geyser by giving better heat storage unit. PCM material can store 5 to 14 times more heat per unit volume than conventional geyser. PCM encapsulation inside the modified geyser can hold or conserve heat energy for a much longer time as compared with ordinary geyser, in this paper to improve the thermal capacity of domestic geyser an experiment has done and examined.Keywords

Location based services became an important application in recent world. Users can search a location using smart phones and can also track the location. It is also possible for the users to retrieve information about the nearest location. The objective of this paper is to reduce the respond time of the server for the user queries. A proxy based approach is proposed to reduce the waiting time of the user and to increase the information about the location. Many location based services, provides details about the user queries. The proxy based approach creates an Estimated Valid Region which reduces the number of queries approaching the server there by reducing the waiting time of the mobile clients due to server load.Keywords
