Temp in baggage hold

What is the average temperature in the baggage hold for commercial airlines on Airbus/Boeing aircraft ?

Will depend much on altitude. Besides, why ask for an "average"? Explaining the question might help in getting useful answers.

The temperature should never be either too warm or too cold, because live animals travel in the baggage hold.

Someone I know will have to travel with a medical electronic device, much too large for carry-on luggage. The equipment may not go under 0°C.

Thanks for the info.

The cargo holds of a passenger aircraft are pressurized and its air temperature remains positive throughout the flight.
The ECS, Environmental Control System, provides the aircraft pressurization and air temperature as required through the different zones. Therefore the conditioned air is, after being circulated through the cabin, forced down to the holds before being partially recirculated (*) via the recirc fans and HEPA filters.
This air is routed down along the sidewalls of the hold as these are not as well insulated as the cabin walls and are directly exposed to the external air which is at very low, negative, temperatures at high altitudes.

So goods, or live animals, may be safely transported inside the cargo hold but should never been placed next to the fuselage skin.
On wide body aircraft, live animals and temp sensitive goods are usually placed in the "bulk hold" whose temperature may be set separately at a higher value than the FWD and AFT holds.

Therefore do mention this while checking in. The package will be specifically identified and a label applied.

(*) for some reason, the air from toilets and galleys are not recirculated and discharged directly out.

Maybe also specify the aircraft in more detail. B777 allows certain temperature control, B737 not. But it is supposed to be positive all the time.
