Sizing chilling system

[rtshfd]

Are there any standard formulas for properly sizing a general purpose cooling system? Our equipment is as followed:

Heating:

* 300 G steam jacketed still

* 300 G mash-tun

* 1,000,000 btu steam boiler

Cooling:

* Product condenser: 3-8 G/min flow rate

* 4 jacketed 300 G fermenters

* Flow-through wort chiller

Assume 1-2 runs a day.

I understand it's a balance between chiller capacity and resevoir size. To draw from someone elses analogy i found here: if the boiler is the engine, what would be the most cost efficient way to "break" this system? I'm thinking a small chiller with a large water resevoir...what size though?

5 to 8 HP should do it, depending where you're located and if you're using chilled water for the fermenters as well.

Minimum 500 to 600 gallon reservoir, larger if you intend on multiple mash cools per day.
