Mobile cabin with ventilation system and a method for ventilation thereof

1. A mobile cabin with a ventilation system comprising:

a ceiling, a floor, two side wall panels, a back wall panel, and a front wall panel, wherein

the ceiling comprises an inner layer and an outer layer, and

the side wall panels comprise an inner layer and an outer layer, and the outer layer extends lower down than the inner layer,

either the back wall panel or the front wall panel or both comprise a door,

and the ventilation system comprises:

at least one straight one-channel air inlet passage in between the inner and the outer layer of the ceiling connecting at least one ventilator penetrating the outer layer of the ceiling and two air inlets penetrating the inner layer of the ceiling proximate to connection of the ceiling and the side walls, whereby air drawn through the at least one ventilator is directed via the at least one straight one-channel air inlet passage through the two air inlets into an inner space of the cabin;

the ventilation system further comprises at least one air outlet formed as a gap between a lower end of the inner layer of at least one of the side wall panels and the floor panel and configured to lead the air from the inner space of the cabin into a space between the inner and outer layers of the at least one side wall panel and further down toward an open lower end of the space between the outer and the inner layers of the at least one side wall;

and wherein

the cabin further has adjustable support legs configured to support the cabin and to allow the open lower end of the space between the outer and the inner layers of the at least one side wall panel to be above ground to enable air outflow when the cabin is in use, and 360° rotating wheels configured to ease moving the cabin when needed, and

at least one connection element and at least one fastener configured to detachably connect the cabin to a second cabin.

2. The cabin according to claim 1 , wherein when the cabin is in use, the support legs are adjusted into a position where the cabin rests on the support legs and the wheels are not in contact with the ground surface of the room.

3. The cabin according to claim 1 , wherein when the cabin is not in use, the support legs are adjusted into a position where the cabin rests on the wheels.

4. The cabin according to claim 1 , wherein the support legs are adjustable from within the cabin through the floor.

5. The cabin according to claim 1 , wherein the cabin has two air outlet channels at connection points of the floor panel and the side wall panel.

6. The cabin according to claim 1 , wherein the at least one connection element is a metal rod having threaded ends penetrating the cabin horizontally from the front wall to the back wall the fastener is a nut.

7. The cabin according to claim 6 , wherein the connection element is extendable and connectable with a connection element of the second cabin with the fastener.

8. The cabin according to claim 1 , wherein the back wall panel, the front wall panel or both the back and front wall panels have magnetic attachments for attaching the cabin to the second cabin.

9. The cabin according to claim 1 , wherein the at least one straight one-channel air inlet passage comprises partition walls forming a labyrinth structure inside the air inlet passage.

10. A method for ventilation of a mobile cabin of claim 1 , comprising:

directing the air from the at least one ventilator through the outer layer of the ceiling into the straight one channel air passage and further through the inner layer of the ceiling through the two inlets proximate to connection of the ceiling and the side walls into inside of the cabin;

expelling the air from the cabin through the gap forming an air outlet channel at the connection point of the side wall panel and the floor panel into the space between the inner and outer layers of at least one side wall panel, and further down toward an open lower end of the space between the outer and the inner layers of the side wall panel into the surrounding environment while the adjustable support legs support the cabin and allow the open lower end of the space between the outer and the inner layers of the at least one side wall panel to be above ground; and

adjusting amount of extracted air so that sufficient air circulation is ensured inside the cabin and the sounds from the external environment do not exceed a desired limit.

11. The method according to claim 10 , wherein the cabin has two air outlet channels at connection points of the floor panel and the side wall panel.

12. The method according to claim 10 , wherein a labyrinth is formed in the straight one channel air passage.
