Abstract

The use of steam compression refrigeration systems is growing both domestically and commercially. The impact of electrical energy consumption in this sector is quite large compared to the need for electrical energy in other electronic equipment. Various efforts were made to be able to reduce the consumption of electrical energy for the cooling system. One of the efforts made by utilizing the natural potential of energy around is solar energy as a source of electrical energy in the mango freezing unit. This fruit is one of the main commodities in West Java, especially in Indramayu Regency. This study aims to determine the performance of the use of solar energy and the need for electrical energy for freezing mango fruit. In the process, freezing is carried out at temperatures below the freezing point of the ingredients/food. Good freezing usually ranges from -12 oC to -24oC. With this temperature, food can last up to 3 to 12 months. Although for freezing mango fruit, it is necessary to have additional treatment so as not to damage the physical structure and quality of the fruit. The method used is to use solar panels as a source of electrical energy in the mango freezing unit. From the tests carried out with variations in the tilt angle of the solar panels, 0°, 20°, and 40° which then from the calculation analysis it is known the comparative value of performance/efficiency and also the consumption of electrical energy generated from each angle of inclination

Abstract

Given the increasing concerns about the environmental impact of fossil fuel-based electricity sources, effective efforts are needed to encourage the use of green energy to meet electricity needs, especially for buildings. Air conditioning systems generally contribute the largest electricity consumption in commercial buildings, so planning an energy conservation system is very important. This study designs a building air conditioning system that uses solar power plants (PLTS) as a power source, by applying the principles of district cooling and cold thermal energy storage (CTS) with ice slurry to optimize the performance of the cooling system. With a case study in a building in Jakarta, Indonesia, this study aims to determine the capacity of the PV system and CTES that can reduce energy consumption and emissions, while considering the costs involved. This study shows 3 CTES charging schemes. In this study, a comparison of several CTES charging schemes shows that the charging scheme using a hybrid power supply is the most cost-efficient option, followed by the off-grid scheme, while the conventional system is the most expensive due to the high cost of electricity. Overall, the CTES system with ice slurry is not only a technological innovation, but also a strategic step towards a more environmentally friendly and energy-efficient building system, where energy needs are balanced with the principle of long-term sustainability.
