CENTRAL CONTROL TYPE AIR-CONDITIONING SYSTEM AND CENTRAL CONTROL METHOD OF AIR-CONDITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To separate and collect total operation data within a fixed time and outside a fixed time by collecting operation data for each indoor machine or each system to be controlled at a main controller side. SOLUTION: For example, a communicator adapter 3-2 outputs an operation information request command at each specific timing for collecting the operation data of an indoor machine 20-3 and an indoor machine 20-4, and the indoor machines 20-3 and 20-4 transmit operation data to a communication adapter 3-2 at each specific timing corresponding to the operation information request command. As a result, the communication adapter 3-2 totals operation data outside a fixed time and transmits the totaling result to a main controller 2 appropriately. Then, the main controller 2 calculates the ratio of the amount of used energy of a second system to be controlled for the amount of used energy of an entire central control type air-conditioning system according to the operation condition of the indoor machines 20-3 and 20-4, and calculates and integrates a charge in the second system to be controlled from the energy proportional division rate.
