In sport therapy, ice bath cooling is a treatment to rehabilitate soft tissue and muscle trauma after a period of intense exercise. Rehabilitation is important for an athlete to maintain their performance at all time. This project is aimed to introduce a proper arrangement of inlet and outlet nozzles of a square athlete ice-bath pool system currently used at the National Sports Institute (ISN), Malaysia . The challenge is to have the most efficient arrangement to lower the temperature of the water from ambient temperature to11°C. In this study, the system is constructed based on the ambience, dimensions and cooling system used in the national institute. Analysis is performed for four (4) arrangements according to different position of inlet and outlet of the water to the pool. Amazingly, analysis shows that the common arrangement of placing the flow inlet and outlet adjacent to each other gives the most inefficient result. The study also prove that the optimum arrangement is a placement that has the longest distance between inlet and outlet of the water. This finding agrees well with the preassumption where the higher difference between the inlet water temperature as compared to the outlet water temperature will give higher cooling effect to the system. Quantitatively, 21% improvement of efficiency was achieved by rearranging the inlet-outlet nozzles from adjacent to diagonal corners of the pool. Without any complicated modification of the system, a significant improvement was achieved through this work.
