Abstract:
Method for reducing the number of water vapour molecules per unit volume in a housing having a plurality of sides, the method comprising:perforating one of said plurality of sides of the housing with at least one through hole and reducing the thermal inertia of the perforated side; andreducing the thermal inertia of the one side of the housing by making it thinner in thickness than the other sides of the housing, all of said sides being made of the same material, so that when surroundings outside of the housing have a lower temperature than an interior of the housing the temperature of said one side with reduced thermal inertia falls more quickly than that of the other sides thereby causing more water molecules to leave the housing through the at least one through hole in the perforated side of the housing than to enter the housing through the at least one through hole.
