Drying of food products in open air under sun is the most common and easiest way of drying. However, it cannot assure the hygiene of the dried product because of the involvement of wind-borne dust, rain, insects, rodents and birds. This will affects the quality of the product and hence may have contrary economic effects on domestics and global markets. Some of the problems associated with open-air sun drying can be solved through the use of a cabinet type or indirect type solar dryer. The major drawback of all these types of conventional solar dryers is that they cannot be used in cloudy weather or during night time. By incorporating Thermal Energy Storage (TES) we can make use of the dryer throughout the day or at least during late evenings. Water is one of the best sensible TES medium within its operating range. Solar water heater is a device used to collect solar energy and heat up water without any electrical or fossil fuel aid. So the idea of this project is to incorporate solar dryer with solar water heater so that the dryer can be used even at late evenings or in cloudy weather, and also it can be used as water heater for hot water consumption

Abstract: Solar energy, the renewable energy is only available at certain hour. So it is essential to develop efficient, economical solar thermal energy storage. Thermal energy storage (TES) systems provide several alternatives for efficient energy use and conservation. Phase change materials (PCMs) for TES are materials supplying thermal regulation at particular phase change temperatures by absorbing and emitting the heat of the medium. TES in general and PCMs in particular, absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling process. PCMs possesses the ability of latent thermal energy change their state with a certain temperature. Paraffin is the PCM used in this research. Paraffin is being added to a solar water heater to store thermal energy at daylight and supply the stored energy to the heat pipe when the sundown. From this research, it is found that the solar water heater with paraffin need longer heating time than the conventional solar water heater but it could provide steadier heating performance and warm water even when the sun was down.

Hospitality is a relatively large energy user in the tourism sector. The application of renewable energy in this field will certainly save energy and contribute to reduce the effect of global warming. An interesting application to study is the use of solar energy for preparing hot water in hotel. This study is a literature study that explored research articles on solar water heater, especially used in hospitality, that have been published. Studies on solar energy have always increased over the past five years, 66.2% of which were in the field of solar thermal energy, where 11.2% of solar thermal energy researches were related to the use of solar energy for the process of heating water. For the research originating from Indonesia, the figures are 48.7% and 6.6% respectively. There is no research on the use of solar water heater in Indonesia. Research on tourism in Indonesia itself tends to decline. A simple example of simulation about solar water heating system using TRNSYS 18 simulation program was presented to motivate researchers in this field.

In the solar dryer is a device in which drying the substance with the help of only solar energy. In this system we observe that the time take to perform the operation high and the effectiveness is very low, and availability also low. With the help of thermal energy storage device, we update the solar dryer. In solar dryer with thermal energy storage device. The energy used is solar as well as thermal energy, availability is increase and effectiveness is also increase. When the blower switch is on the atmospheric air is drawn in the copper tube, surrounding of the copper tube is hot water is available. Hence the hot water is available the atmospheric air is exchange the heat the air get hot this hot air is hot water is move to container (vessel). Then the temperature of the container (vessel) increase. Hence the time take for the perform operation is decrease.

Energy Sharing

Due to increased grid problems caused by renewable energy systems being used to realize zero energy buildings and communities, the importance of energy sharing and self-sufficiency of renewable energy also increased. In this study, the energy performance of an energy-sharing community was investigated to improve its energy efficiency and renewable energy self-sufficiency. For a case study, a smart village was selected via detailed simulation. In this study, the thermal energy for cooling, heating, and domestic hot water was produced by ground source heat pumps, which were integrated with thermal energy storage (TES) with solar energy systems. We observed that the ST system integrated with TES showed higher self-sufficiency with grid interaction than the PV and PVT systems. This was due to the heat pump system being connected to thermal energy storage, which was operated as an energy storage system. Consequently, we also found that the ST system had a lower operating energy, CO2 emissions, and operating costs compared with the PV and PVT systems.
