Is it necessary to set up a constant temperature and humidity machine in the weapon room in air conditioning design? Or set up dehumidifier and ventilation system?

There are clear requirements for temperature and humidity in weapons storage, as long as the relevant air conditioning and ventilation design is carried out according to this requirement.

Generally speaking, weapons storage requires relatively high humidity, because it will adversely affect weapons in a high humidity environment.

It is suggested to find the relevant military standards first and see the requirements for weapons storage in the standards.
