Abstract

Availability of hot water for showers is an important requirement for households and industry. For the hospitality industry, this facility should  held in order to be classified into five-star hotel. So the hotel management had to incur huge costs each month to supply the hot water in every hotel room. One solution for hot water supply cheapest and effective for household and commercial needs is to use solar water heater (SWH). SWH available today still has a weakness, namely the price of the initial investment is still relatively expensive and require a high operational cost because they use an extra heater. Investigation methods are being developed to address the weaknesses of SWH is by adding TES, using phase change material. This study aims to determine the ability of thermal energy storage (TES) in the flat plate solar collector on the charging and discharging process. Type of phase change material used in this study was 19.5kg of paraffin wax. SWH type of flat plate collector with the addition of TES has been created and tested on a small scale for a few days of testing. Test results on the charging process can be concluded that the mass of melted paraffin wax which is as much as 18.81kg and the highest thermal efficiency obtained is 44.28%. Meanwhile in the process of discharging the highest volume of hot water obtained is 40 liters for a minimum temperature of 35°C and the highest thermal efficiency is 46.81%.
