A water-cooled chiller in the University has a rated input power of 1050 kW. The Energy Efficiency Ratio [(btu/hr)/watt] vs. Cooling load (%) of the chiller provided by the manufacturer is shown in Figure. The latest maintenance routine was performed when the cooling load was at 50%, the temperature sensor at the chilled water supply was found to be malfunctioned, while the chilled water return temperature was measured to be 15 °C, and the water flow rate was 0.24 m³/s. Given that the specific heat capacity of water = 4.189 kJ/kg.K and the water density = 0.99975 g/cm³. Determine the followings: a. Determine the cooling capacity at that time, in kW b. Determine the outlet temperature at that time, in °C. 35 30 25 20 15 10 5 20 EER vs. Cooling load (%) 40 60 80 100
