Critical Space Temperature Rise Over Time During A Power Outage
Critical Space Temperature Rise Over Time During A Power Outage
(OP)
What program would you recommend our how would you go about calculating the temperature rise of a cold storage facility during a power outage on a design day? Assume the power outage would cause the HVAC / lighting / room equipment to be off and the outside air and exhaust air dampers to be closed.

While you may want to do hand calculations for envelope, amount of temperature rise will depend heavily upon ambient conditions and the storage contents and their temperature. I've seen this same question asked in customer meetings with the COE when they needed to have a contingency contract for an 18-wheeler to drive up within a specified time frame for emergency power and 4 days operating fuel. Perhaps picking out worst case, say July 19 at 1500, and only thing left in cold storage is mission critical only (such as as panedemic supplies included with MTOE deployables). This is not a routine or simple solution, at least if that is the case.
Most surprsing is that the cold, dry storage facilties would be suppled with only EEC power, not full back up.

time required for temp rise = Heat energy/Heat load
