This study focuses on designing an air conditioning system that can provide the required thermal conditions in an indoor squash court. That will be followed by the World Squash Federation (WSF) and the Specialized College for Sports Medicine in America (ACSM), which suggested keeping the temperature of the air inside every facility used for intense activity to be at the range of 20-22 C, with relative humidity levels lower than 60%. The World Squash Federation recommended the air temperature range between 15-25 °C, with the ideal range of 18-20 °C with relative humidity levels lower than 60%, considering maintaining ball surface heat at 40-45 °C or above. Suppose the ball's temperature decreases below that range. In that case, the ball's rebound will be decreased, which will be done by investigating temperature and velocity distribution, relative humidity, 𝑐𝑜2 level, and the effect of changing the inlet velocity for each air conditioning system design. The difference between each air conditioning system will be in the location and number of supply and extract openings. The study was carried out using CFD simulation by ANSYS FLUENT 17.2. The CFD modeling techniques will solve the continuity, momentum, and energy equations, allowing better and more meaningful predictions of the flow patterns by using the realizable k-𝜀 as a turbulence model and its function of enhanced wall treatment.
