Ventilation system, ventilation method, ventilation control device, and non-transitory computer-readable recording medium

A ventilation method, comprising:

• acquiring wind information regarding the outdoor wind;
• ordering an air supplier/exhauster comprising air supply function and exhaust function to conduct one of two operations, an air supply operation to bring outdoor air into a building or an exhaust operation to exhaust air in the building to outside of the building, based on the acquired wind information for ventilating the building;
• determining whether the air supplier/exhauster is situated windward or leeward;
• conducting the ventilation through a ventilation passage from the air supplier/exhauster to a vent provided to the building when the air supplier/exhauster conducts the air supply operation, and alternatively conducting the ventilation through the ventilation passage from the vent to the air supplier/exhauster when the air supplier/exhauster conducts the exhaust operation, and further comprising:
• ordering the air supplier/exhauster to conduct the air supply operation when the air supplier/exhauster is situated windward, and alternatively ordering the air supplier/exhauster to conduct the exhaust operation when the air supplier/exhauster is situated leeward.

A ventilation control device controlling ventilation of a building, comprising:

• a wind information acquirer acquiring wind information regarding the outdoor wind;
• and
• an air supply/exhaust controller controlling operation of an air supplier/exhauster comprising air supply function and exhaust function,
• wherein upon operating the air supplier/exhauster, the air supply/exhaust controller determines which the air supplier/exhauster conducts, an air supply operation to bring outdoor air into the building or an exhaust operation to exhaust air in the building to outside of the building, based on the wind information acquired by the wind information acquirer, and determines whether the air supplier/exhauster is situated windward or leeward;
• the ventilation through a ventilation passage from the air supplier/exhauster to a vent provided to the building is conducted when the air supplier/exhauster conducts the air supply operation, and alternatively the ventilation through the ventilation passage from the vent to the air supplier/exhauster is conducted when the air supplier/exhauster conducts the exhaust operation, and wherein
• the air supply/exhaust controller orders the air supplier/exhauster to conduct the air supply operation when the air supplier/exhauster is situated windward, and alternatively orders the air supplier/exhauster to conduct the exhaust operation when the air supplier/exhauster is situated leeward.

A non-transitory computer-readable recording medium having stored thereof a program allowing a computer controlling ventilation of a building to function as:

• a wind information acquirer acquiring wind information regarding the outdoor wind;
• and
• an air supply/exhaust controller controlling operation of an air supplier/exhauster comprising air supply function and exhaust function,
• wherein upon operating the air supplier/exhauster, the air supply/exhaust controller determines which operation the air supplier/exhauster conducts, an air supply operation to bring outdoor air into the building or an exhaust operation to exhaust air in the building to outside of the building, based on the wind information acquired by the wind information acquirer,
• the ventilation through a ventilation passage from the air supplier/exhauster to a vent provided in the building is conducted when the air supplier/exhauster conducts the air supply operation, and alternatively the ventilation through the ventilation passage from the vent to the air supplier/exhauster is conducted when the air supplier/exhauster conducts the exhaust operation, and wherein
• the air supply/exhaust controller orders the air supplier/exhauster to conduct the air supply operation when the air supplier/exhauster is situated windward, and alternatively orders the air supplier/exhauster to conduct the exhaust operation when the air supplier/exhauster is situated leeward.
