High Utility

The solar water heater is a method of utilizing solar thermal energy by storing heat energy in water which can be used directly. Solar thermal energy has a high utility potential. It has a power of 1 kW/m2 on average on the surface of the earth with energy up to 7 kWh/m2/day on average per year. One of the uses of the solar water heater is that it can be implemented in the milk pasteurization system. The research equipment consists of an accumulator vessel with an area of 2x2 m2 and a water pipe collector. The water that had been heated in an accumulator (thermos) was used directly as the heating source in the milk pasteurization process. Meanwhile, the most common heating method used in the pasteurization process is electricity and gas energy. The result showed that using 82oC of accumulator water, it took 12 minutes (14.48–15.00) to reach the milk temperature needed in the pasteurization process which is 70oC for 6.75 litres of milk. The efficiency of solar heat energy absorption by an accumulator is 47%. This value can be increased by increasing the volume of water.

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.

The Impact

Aiming at the problems of water temperature and water level control system of conventional solar water heater and low solar thermal control efficiency, this paper developed an AT series single-chip solar water heater control system for rural areas. In this paper, the detailed design of hardware and software is presented, and the method of evaluating the collector efficiency is simplified by the temperature rise rate and solar irradiance of the collector plate. The software compensation algorithm we adopted can effectively reduce the impact of different water quality on water level measurement and improve solar thermal control efficiency. It is found that the control system designed in this paper has the characteristics of low cost, high safety, and strong practicability.

The Cost

Energy saving today is an integral part of the development strategy of agricultural organizations. Considerable attention is paid to the modernization and automation of technological processes in agricultural enterprises, which can improve the quality of work and reduce the cost of production. The direction of modernization is to reduce the consumption of electric energy by improving the water treatment system in livestock complexes. (Research purpose) The research purpose is to determine the potential of solar energy used in the Nizhny Novgorod region and to determine the possibility of its use for water heating in livestock complexes and to consider the cost-effectiveness of using a device to heat water through solar energy. (Materials and methods) Authors used an improved algorithm of Pixer and Laszlo, applied in the NASA project «Surface meteorology and Energy», which allows to calculate the optimal angle of inclination of the device for heating water. (Results and discussion) Designed a mock-up of a livestock complex with a solar water heater installed on the roof, protected by patent for invention No. 2672656. A mathematical model was designed experimentally to predict the results of the plant operation in non-described modes. (Conclusions) The article reveales the optimal capacity of the circulation pump. Authors have created a mathematical model of the device that allows to predict the water heating in a certain period of time. The article presents the calculations on the energy and economic efficiency of using a solar water heater. An electric energy saving of about 30 percent, in the economic equivalent of 35 percent.
