D. Wet cooling Tower The wet cooling tower supplies cooling water to the condenser of the chiller system at a rate of 200 liters/min. The cooling water absorbs the thermal load from the condenser and returns to the cooling tower at 34C. Air enters the cooling tower at 1atm and 28C and leaves saturated at 34C. 1. Plot the variations in cooling water supply temperature to the condenser and the heat absorption rate at the condenser when the relative humidity of the inlet air varies from 50% to 100%RH. Assume the air flow rate is constant at 60 liters per minute. (CO3) 2. Explain the reasons why cooling towers are a necessary sub-system in district cooling airconditioning systems. (CO1)
