Ideal load-leveling chiller size calculator

An ideal lossless load-leveling plant produces daily cooling at a steady rate across its running hours.

Units

Q_{\text{level}} = \frac{C_{\text{day}}}{t_{\text{run}}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

Q_{\text{level}} = \frac{4200}{24} = 175
