Cooling capacity equation

WebApr 28, 2024 · 105,706.9 BTU/hour / 12,000 = 8.81 t of cooling needed. To determine the future cooling needs of this data closet, we multiply the total IT heat output by 1.5, so 12,036 W x 1.5 = 18,054 W. Adding this new number to the existing ones gives us a future total cooling requirement of 37,017.412 W or 10.5 t of cooling. WebSensible cooling capacity determines the temperature reduction capability of the air conditioner. Usually, it is about 80% of the total cooling capacity of the air conditioner. Meanwhile, the remaining is the latent cooling capacity which determines the moisture extraction capability of air conditioners. Sensible heat and latent heat are basic ...
