Document Type and Number:
WIPO Patent Application WO/2020/213655
Kind Code:
A1
Abstract:
The present invention addresses reverse airflow occurring in the ducts of an air conditioning system that uses ducts to supply conditioned air to a plurality of locations inside a building. A heat exchanger unit (10) includes a usage-side heat exchanger (11). A plurality of ducts (20) are connected to the heat exchanger unit (10). A plurality of fan units (30) draw in conditioned air from the heat exchanger unit (10) via the plurality of ducts (20) and supply the same to a plurality of outlets (71). A differential pressure sensor (121), which is a detection device, detects reverse airflow heading toward the heat exchanger unit (10) from at least one outlet (71) among the plurality of outlets (71) in a plurality of distribution flow paths formed from the plurality of ducts (20), the plurality of fan units (30), and the outlets (71) of a plurality of outlet units (70).
