<p>PURPOSE:To provide the subject box-type storehouse suitable for e.g. domestic use, so designed that a nitrogen feeder is actuated according to the variation in the gas composition in a storage chamber to feed nitrogen-enriched gas into said chamber and a humidity regulator is actuated according to the detection degree of the humidity detection means to control the humidity in said chamber. CONSTITUTION:A nitrogen feeder 30 is actuated by a controller 70 according to the variation in the gas composition in a storage chamber 2 to feed said chamber with nitrogen gas or nitrogen-enriched gas, thus said chamber is put in a nitrogen-enriched state (e.g., nitrogen concentration is 99-90%). When the humidity in the storage chamber is varied, a humidity regulator 77 is actuated to humidify or dehumidify the gas in said chamber.</p> |
