Fresh air in the Cold stores
One of the sites had a audit from International firm. They want an explanation on why fresh air in not required in the cold stores like what we provide for Airconditioning.
Is there any good info on this?
There is a combination of chiller / freezers in the project.

Was this firm an insurance company or some safety audit?If all else fails, ask for help.

Re: Fresh air in the Cold stores
I agree with US ICEMAN,
Only a comment I want to do:
If it is cold stores with living products such as fruits, vegetables and so on and if the products are to be storage during much time without service to the cold store so in that case you would to need a ventilator working a "couple" of hours/day to replace the air inside by fresh air outside.
RegardsTo make progress is never good enough, I want to do better and better and better

Re: Fresh air in the Cold stores
ERM!
Living products in a cold store NO!
In a Chill Room Maybe!
The whole idea of storing within a cold store at a minimum of -18c.
Is because everything is inert at that temperature or below.
Even bacteria cannot exist at these temperatures.
Consider that meats and vegetables, fruit juices, tobacco etc. etc are shipped all around the world.
In this environment.
Add fresh air and the chamber heat load goes through the roof.
More importantly the stored produce would spoil!
If this is a customer ask them to pay for dedicated chambers and a disclaimer as to how long the product will keep!
I have heard some stupid things but this one is tops!

Re: Fresh air in the Cold stores
No need to apologise Sandro.
Basically a cold store is either, so you were correct if WE interpret the original question the way you did.
I would tend to call that a chill room.
Sorry from me, if I appeared to have a go at you.
Still we have managed to clarify a few things hopefully?

Re: Fresh air in the Cold stores
Here is another example of why we have so many issues in this business. We have too many names for things that can be used to indicate the same thing or something different depending on where you come from in the world.
I'm not saying either is wrong, only that each can mean something different to other people. And, when we use the terms we are familiar with someone else may have a completely different idea of their definition.
cold stores rooms & refrigerated storesIf all else fails, ask for help.

Re: Fresh air in the Cold stores
YOu may be surprised that this issue came up at Mcdonalds big warehouse. The info provided by all is fine & good enough, but you know auditors, if they get a reference from a book/ handbook, that is good enough for them.
I shall compile all these points to see if they are satisfied.

Dear US ICEMAN
You have nice way of putting up the things. I was just referring to your posts on Ammonia DX systems & it was very nicely written

There is a great saying about consultants, and auditors drop into same league.
"consultants are the ones that come out of the hills and kill all the wounded after the battle is over. "
