  • vegetables absorb oxygen and emit carbon dioxide, so the storage space 3 lacks oxygen. To prevent this, a very small amount of fresh air is intermittently introduced from the outside air inlet 1a. The amount of heat associated with the introduction of air is extremely small and has little effect on the temperature of storage space 3.
