commercial cold storage
how would one estimate the REQUIRED cooling capacity in watts of a 20000 square feet cold storage with outside temperature at plus 104 Fahrenheit and inside to be maintained at minus 32 Fahrenheit?
is there a simple rule of thumb or there is some elaborate formula?

Re: commercial cold storage
thanks for taking your time and replying to my question, the frozen meat items are going to arrive already frozen, in reefer trucks, and the size of the cold storage is 75 feet by 60 feet by 12 feet, the outside temperature being 104 degrees F, and inside we want to have minus 32 degrees F, there is only one sliding door to warehouse, which is going to open/close at least 6 times every hour for 8 hours during the day.
The walls/ceiling of the warehouse are from PUF panels, 6 inches thick.

Re: commercial cold storage
Is it just a rule of thumb that you need? Are you the project manager in charge of a new installation or is it an upgrade of some existing plant?
Ideally you should include a refrigeration expert in your deliberations.Brian - Newton Abbot, Devon, UK
