QUESTION:I am in the process of modeling a cold storage facility and would like
some details if anyone has some. I need to know what types of vents
and equipment would be found on the roof of such a building. I have
seen a few cold storage warehouses and some of them have large tanks
outside the building and some don't. I assume the tanks are for some
type of coolant. The new Kwik Trip cold storage here in La Crosse, WI
has what looks like an old semi tank trailer beside the building with
a compressor on the end. I can't get within 100 feet of this building
so I can't get any photos for modeling. Anyone have any pictures of
this type of equipment? Any help would be appreciated.
ANSWER: There are two types of refrigeration installations common for cold storage
warehouses.
The first is the use of packaged freon equipment which is usually
identified by several, sometimes dozens, of rectangular pieces of equipment
on the roof. Each piece of equipment is typically part of a separate
refrigeration system and is connected to separate air cooling coil inside
the cold rooms. (The equipment to most will look like the air conditioning
equipment that is on the roof of many commercial buildings today.)
The second is the use of a central refrigeration system which is common in
the larger facilities. The refrigerant used can be either a freon or very
often ammonia and is piped back from the air cooling coils in the cold
rooms to a compressor room. From the outside of the building there is
often little evidence of a refrigeration system except for at least one
large rectangular box with fans located on a stand outside the compressor
room or on the roof above the compressor room. This is the condenser which
releases the heat removed from the cold rooms to the atmosphere. Sometimes
the systems are so large that it makes sense to place one or more pieces of
the refrigeration equipment outside the compressor room and often the
refrigerant vessels are choosen.
Further some of these "central" installations place the refrigerant piping
on the roof and drop the pipes into the building where the air cooling
coils are located. Finally some installations choose to install penthouses
above the cold rooms which house the air cooling coils above the roof.
