Abstract
A plurality of central controllers that each control a refrigeration cycle device and receive power consumption data of the refrigeration cycle device and a central management device that performs pro-rata calculation by use of at least the power consumption data and manages the plurality of central controllers are provided. The central management device includes a first data unit that stores the power consumption data and a result of the pro-rata calculation and a second data unit that stores data output from each of the plurality of central controllers, and the plurality of central controllers each include a third data unit that stores operation data of the refrigeration cycle device and a fourth data unit that stores data of the first data unit output from the central management device.
Claims10
An air-conditioning system comprising:
- a plurality of central controllers each configured to control a refrigeration cycle device and receive power consumption data of the refrigeration cycle device;
- and
- a central management device configured to
- perform pro-rata calculation using power consumption data of the refrigeration cycle device input directly from the refrigeration cycle device, and
- manage the plurality of central controllers,
- the central management device including
- a first data unit configured to store the power consumption data and a result of the pro-rata calculation, and
- a second data unit configured to store data output from each of the plurality of central controllers,
- each of the plurality of central controllers including
- a third data unit configured to store operation data of the refrigeration cycle device, and
- a fourth data unit configured to store data of the first data unit output from the central management device,
- the central management device including first identification number data stored in the first data unit, the first identification number data being used to identify whether or not the central management device corresponds to each of the plurality of central controllers, and
- each of the plurality of central controllers including second identification number data stored in the third data unit, the second identification number data being compared with the first identification number data.
An air-conditioning system comprising:
- a plurality of central controllers each configured to control a refrigeration cycle device and receive power consumption data of the refrigeration cycle device;
- and
- a central management device configured to
- perform pro-rata calculation using power consumption data of the refrigeration cycle device input directly from the refrigeration cycle device, and
- manage the plurality of central controllers,
- the central management device including
- a first data unit configured to store the power consumption data and a result of the pro-rata calculation, and
- a second data unit configured to store data output from each of the plurality of central controllers,
- each of the plurality of central controllers including
- a third data unit configured to store operation data of the refrigeration cycle device, and
- a fourth data unit configured to store data of the first data unit output from the central management device, and
- the central management device or each of the plurality of central controllers being configured
- to set a flag when data stored in a corresponding one of the first data unit and the third data unit is corrected, and
- to duplicate data, to which the flag is set, among data stored in the first data unit and the third data unit.
