Abstract

The objectives of this study are to evaluate the decrement rate in the ice bath water temperature in different environment conditions and study the decrement rate in the ice bath water temperature using a different pump capability. First, in the study of different environment conditions, the decrement rates of water temperature were tested with and without top cover. In addition, both conditions were tested with their environments i-exposed directly to sunlight, ii-exposed indirectly to sunlight and iii-tested in the air-conditioned rooms. The study was done experimentally using a chiller provided by Institut Jantung Negara (ISN). Second, in the study of the decrement rate in the ice bath water temperature, two pumps with Hilea chiller are considered. Two pumps with different flow rate were used using Hailea chiller model HS-90A where 1400 litre per hour and 4000 litre per hour of pump were tested. All temperature data for each experiment were taken and plotted in the graph using linear equation y = mx + c for each experiment. Using the equation, the duration of time required for the ice bath water temperature reaches 12degC can be evaluated. Therefore, the best experimental conditions can be determined through the shortest period of time. Where the test done in air-conditioned rooms and bath tub with top cover were the best conditions for ice bath cooling process. Whereas, for the test with different pump flow rate, pump A with 1400 litre per hour has a better rate of temperature decrease compared to pumps B with 4000 litres per hour.
