Ventiladorder

In the past, air passed through the lower watermill cellar through the black grille next to the house, and the "door". When the watermill was stopped and the mill reservoir was broken the wind passed through the cellar by the black grill and the water tunnel.

When the workshop was built the back wall closed off that venting, and all humidity ended up in the garage. Apparently no one before realised that the black grill is a ventilation opening.

We tried to mend the humidity situation before, see solar ventilator. That did work well, especially for the atmosphere in the kitchen. However, ventilador 2 in the garage did not work at all. The humidity and volume of air are too great.

We asked Emilio (the builder) to make a nice big hole, where immediately very humid air started to pass, in large volumes.

The solar ventilator passes 60 m3 per hour to the outside, but only when the sun shines. In the evening and in the morning you could smell the cellar a bit, as the ventilation is then halted. We will switch to the grid.

This 230V ventilator has a capacity of 180 m3 per hour, day and night. It moves the air from the first cellar under the kitchen to the watermill cellar, and from there to the new opening in the back of the garage and to the black grille next to the house.

Intention is that no more air flows from cellar to the kitchen, and to dry out the watermill cellar, so the garage stays dry. There is a sheet of plastic between the back of the garage and the garage, so the humid air is forced out through the new window.

It could be the solar ventilator in cellar 1 is no longer necessary, or even that the pipe up and out to the back of the house is better closed off. We'll see (smell).
