Air dome device capable of maintaining positive pressure and controlling temperature for cultivating crops

An air dome device comprising:

• a membrane unit being formed of a membrane and being extended in one direction to form an inner space in which a set pressure is maintained;
• an entrance unit being disposed in front of the membrane unit to allow outside air to flow in and be filtered;
• an air conditioning unit being disposed in the rear of the membrane unit to form an air-conditioned space and to control the temperature and humidity of the outside air flowed in from the entrance unit;
• a branch pipe in the form of a pipe connecting the entrance unit and the air conditioning unit, which is inserted into the ground to provide a path through which the outside air introduced from the entrance unit exchanges heat with ground heat;
• a blower unit being formed with a blower space to blow air in the air-conditioned space or the air in the inner space;
• a distribution unit being disposed on one side of the blower space to distribute air being blown from the blower member;
• and
• a distribution line supplying the air distributed from the distribution member to the inner space.
