  • In case of earth-covered storage, the condensation occurs on surface of wall and stores in summer with high humidity because of low temperature of constructional mass. Therefore, the preventive plans should be considered to protect stores from the damage by corrosion in earth-covered storages. This study aims to suggest the methods of forced ventilation by the air, to solve the problems of construction's surface condensation at the Magazine of igloo type which is similar to earth-covered storages. A fan was installed at the air outlet for exhaust gas to conduct forced ventilation. The surface and indoor temperature were measured, and then the influence of those on condensation was analyzed. The results of this research are follows; 1) Forced ventilation by a fan affects the rise in surface temperature of walls and stores. 2) The condensation on surface of walls and stores was reduced after operating a fan.

  • The compact storage of ammunitions in magazine causes serious dew problem on the surface of the shell. Lots of previous studies try to solve this problem by increasing the temperature of air in military magazine. They tried to reduce relative humidity by increasing the temperature of air, but all of them failed. One of the major reasons of these failures is analysed based on the point of view of physics.
