Web20°F temperature rise as the cooling air travels through the server. This requirement can be expressed by the following formula: Cooling airflow rate in CFM = 154 × Heat load in kW × (Reference Pressure/Local Pressure) (In this expression, the reference pressure is 1 atmosphere and the local pressure depends on the local altitude. WebCooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent …
