MONITORING SYSTEM FOR AIR CONDITIONER

摘要

An air conditioner monitoring system includes: a plurality of air conditioners (10) each including a refrigerant circuit (11) for performing a vapor compression refrigeration cycle; a local controller (60) provided for each of sets of several ones of the air conditioners (10) for receiving data output by the each of sets of several ones of the air conditioners (10), and transmitting predetermined operation data; and a host controller (70) for receiving the operation data of the plurality of air conditioners (10) transmitted by the local controllers (60) through communication lines (53). The host controller (70) calculates air conditioning capability and power consumption of each of the air conditioners (10) in the each of sets of several ones of the air conditioners (10), and calculates energy utilization efficiency of each of the air conditioners (10).
