Cellier en sous sol/en

Description

As the drawing shows, it is a semi-underground cellar used to store vegetables and fruit. Thanks to the difficulty of heat transfer in the underground, the cellar is able to have a constant temperature all year round, 0℃- 5℃. In addition, the tightness of the cellar ensures humidity. It is suitable for onions, garlic, zucchini, potatoes, cabbage, etc.

Making a hole

First, we dig a big pit in the ground.

Construction of the Cellar

And then we build a cellar using stones and cement. Remember to create two exhaust vents. Since in the cellar there are a lot of gases like CO2, CH4, etc. and it lacks O2. So before entering the cellar, we need to open the exhaust vents to have enough O2.

Creation of a sealed entrance

Bury the cellar with soil

Adding water

We have to put some water in the cellar. When it's too cold, water will freeze and produce heat. On the other hand, it will volatilize to absorb the heat.
