Recovering capacity of an Ice Builder when loading and unloading at the same time

[daniel27ad]

Hello,

I am analyzing the capacity of an industrial Ice Water system. The water from this system is cooled via two Ice Builders and nothing else (no chillers).

Most of the information I have found about Ice Builders assumes that for a certain amount of hours they accumulate the ice (demand = 0) and for the other part of the day the ice that was accumulated will be used.

But what happens if the system does not work like that exactly? In my case of study, there is demand throughout the whole day, although is less during the night. Also, the refrigeration system works throughout the whole day too, and there is less capacity available during the day than during the night.

My question is about how diminished is the ice building capacity of the ice builders when working this way comparing the standard way.

For example, say that my ice building period is from 0000 to 0600. Let's compare a system where I will have 0 demand and a supply of 500 TR along those six hours against a system where my demand will be 500 TR but my supply will be 1000 TR. Is there any reference as to how different will be the ice building capacity in one case from the other?

Any articles about this?

I appreciate the help in advance.

In cold climates people with old, poorly insulated, houses, know that to prevent pipes from freezing leaving just a trickle of water flowing will do the trick.

Because as long as there is some mixing removing sensible heat from water will happen, has to happen, before latent heat is removed. Because...physics.

Same will probably happen in your ice builder. If water is flowing to and from your load through the ice/water side you won't make ice.

At least probably not very much.

The manufacturer of your equipment would likely be helpful.
