AIR-CONDITIONING SYSTEM, MANAGEMENT DEVICE, AIR CONDITIONER, SENSOR DATA ACQUISITION METHOD, AND PROGRAM

摘要

A centralized management device (2) comprises a sensor data acquisition unit (200) and an acquisition cycle change unit (203). The sensor data acquisition unit (200) periodically acquires sensor data including the measurement results of one or more sensors of each outdoor unit (5) from each of the one or more outdoor units (5) by communication. When a sign of failure is detected in any of the outdoor units (5), the acquisition cycle change unit (203) makes a change to shorten the acquisition cycle of the sensor data for the outdoor unit (5).
