Re: Cold Storage Design
Hi abbasi,
To design a cold room you will need to know:
1. Size.
2. Substance to be cooled, what temp it goes in, how fast it need to be cooled.
3. Power consumption of light and fan motors.
4. how many times, doors are opened.
5. Storage temp.
6. Walls material, heat transfer rate w/m2/h
Now you can start to design the unit
Peter is defiantly invited to have his say
Good luck
Chemi

Re: Cold Storage Design
Waw, I'm honored Abbasi.
But in this forum, most of those who post regulary can do this of help you.
Chemi covered already the most.
Why not use Coolpack for this?
I should add: running time of the machine/day.
Gas to be used?
Do you have latent heat to cool? (fruit, vegetables...)
Desired humidity in the room?
What kind of brand will you use or is available in your country?
Post eventually a more specific question so that we can help you further or was your question more a general one?
You also have my email adress.
Kind regards.
PeterIt's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Don't forget to allow for fork truck movements and occupancy if it is a large coldroom

I am reminded of an exam question which required a specific answer. The student threw in all he knew, hoping that the relevant bits would be contained within his diatribe and the examiner would lift those bits out and award him.......

[QUOTE=abbasi]Can any body tel me about cold storage design
The following is from the
2002 ASHRAE Refrigeration Handbook (SI) Chapter 13 and is only a small excerpt on cold storage facilities.
Typically, the height of refrigerated spaces is at least 8.5 to 10.5 m
or more clear space between the floor and structural steel to allow
forklift operation. Pallet rack systems use the greater height. The
practical height for stacking pallets without racks is 4.5 to 5.5 m.
The clear space above the pallet stacks is used for air units, air
Figure 1 shows the layout of a one-story –23°C freezer that complies
with current practices. The following essential items and functions
are considered:
• Refrigeration machinery room
• Refrigerated shipping docks with seal-cushion closures on the
doors
• Automatic doors
• Batten doors or strip curtains
• Low-temperature storage held at –23°C or lower
• Pallet-rack systems to facilitate the handling of small lots and to
comply with first-in, first-out inventory, which is required for
some products
• Blast freezer or separate sharp freezer room for isolation of products
being frozen
• Cooler or convertible space
• Space for brokerage offices
• Space for empty pallet storage and repair
• Space for shop and battery charging
• Automatic sprinklers in accordance with National Fire Protection
Association (NFPA) regulations
• Trucker/employee break area
• Valve stations for underfloor heating
• Evaporative condenser(s) location
Other areas that must be in a complete operable facility are
• Electrical area
• Shipping office
• Administration office
• Personnel welfare facilities
