ABSTRACT:
An airconditioner system for integrating multiple areas. A plurality of multi-airconditioners are grouped into some groups. CPU connected in parallel to individual multi-airconditioner groups, that have been distributed and installed in a wide area or building, controls individual multi-airconditioner groups to be operated simultaneously, resulting in a shorter control time. Although an unexpected communication failure occurs in one multi-airconditioner group, the remaining multi-airconditioner groups other than the erroneous multi-airconditioner group can be normally controlled, resulting in increased stability and reliability of an overall airconditioning system.
