Abstract

FASSIP-03 NT loop is a medium-scale experimental facility used for research and development of passive cooling systems based on circulating flow phenomena. Meanwhile, the flow rate of natural circulation still has limitations in the absorption of heat in the heating tank and cooling tank for heat release. The purpose of this study was to analyse the heat transfer in the heating tank section based on variations in water temperature. The research method was carried out experimentally by varying the water temperature setting in the heating tank section, namely 60, 70, 80 and 90 degree celcius during steady state. The experimental results show that the magnitude of natural circulation flow is directly proportional to the increase in the water temperature setting in the heating tank section. The minimum flow rate achieved is 0.67 LPM at a setting temperature of 60 degree celcius Cand the maximum value is 1.47 at a setting temperature of 90 degree celcius. The average heat energy (q) released in the cooling tank section is half of the heat energy received in the heating tank section during steady state.
