Question:
You have been hired to design a cooling system that allows you to air-condition a Data Center with the following characteristics: 1. The load of IT equipment is 110 kw. 2. The temperature should be kept between 18 and 26 degrees Celsius 3. The maximum power supported by UPS equipment is 150 kw 4. Humidity should be maintained between 30 and 60 percent relative humidity. 5. The hot air temperature reaches 35 degrees Celsius 6. IT equipment is arranged in two large rows of racks (one facing the other). another) the aisle between rows is 120 cm wide. 7. The cooling system must be redundant active-passive 8. The aisle between rows will be a contained cold aisle: 9. The total number of racks is 20, for a density of 5.5 kW per rack 10. The racks have a height of 200 cm. 11. Consider using a cooling tower. 12. Calculate the size of the evaporator. 13.Assume also that the condenser of the system is cooled by means of a A flow of 4kg/s of water, which enters the condenser at 27C, cools the condenser and leaves it at 35C to go to be cooled in a "tower of cooling" forced draft against flow. The air entering the tower cooling is at 28C and 50% relative humidity and leaves the tower saturated at 33C. Dimension the required cooling tower size (Air flow in cubic meters per minute and cubic meters of water required for replacement monthly)
