PURPOSE: An air supply device for ventilating a building is provided to reduce energy loss caused by ventilation by exchanging the air passing through a buried air supply duct with the heat stored in a concrete slab. CONSTITUTION: An air supply device for ventilating a building comprises diffusers (10), buried air supply ducts (20), an air supply fan (30), dampers (40), and controllers (50). The diffusers are installed inside of a building (2) and supply external air to the indoor space of the building. The buried air supply ducts are connected to the diffusers and are buried in concrete slabs (4) of the building. The air supply fan sends external air to the diffusers through the buried air supply ducts. The dampers control the amount of the air supplied to the diffusers. The controllers control the amount of the air supplied to the diffusers by controlling the air supply fan and one or more dampers. The air passing through the buried air supply duct is exchanged with the heat stored in the concrete slabs. |
