AIR CONDITIONING METHOD OF BUILDING

摘要

PROBLEM TO BE SOLVED: To provide an air conditioning method of a building suppressing air conditioning energy loss and indoor environment deterioration by a draft or the like by correcting a collapsed air balance between a vertical space and each interior of each room in the building by carrying out a corrective action so as to make a differential pressure or an amount of air movement between the vertical space and the inside of each room zero by means of the existing air conditioners.

SOLUTION: A vertical space 1 penetrating an interior of a building B and a room R1 are connected to each other by gaps or the like. A part of a returned air of the room R1 is mixed with an outside air introduced from an outside air introducing port 5b by an air returning fan 12 of an air conditioner 11 and supplied to the room R1 as an air conditioned air after carrying out a temperature regulation by a heating coil 11b and a cooling coil 11c, and a part of the remainder of the returned air is exhausted from exhaust ports 5a, 5c. A differential pressure between the room R1 and the vertical space 1 is measured by a first measuring device 31, and a rotating speed of the air returning fan 12 or an opening of an exhaust damper 13 is controlled by a control device C so as to make the differential pressure zero.
