Abstract
A plurality of air conditioning units (20, 20) are daisy-chain connected to each other by a switching hub (31) provided in an outdoor unit (30). An integrated transmission line (10A) and internal/external transmission lines (10B) are connected to each other by a gateway (32) connected to the switching hub (31) so as to be capable of separating data transmission.
Claims5
A transmission system for an air conditioner, comprising:
- a plurality of air conditioning units (20) in each of which an outdoor unit (30) and a plurality of indoor units (40) are connected to each other through an internal/external transmission line (10B) so as to be capable of data transmission;
- and
- an integrated transmission line (10A) connecting a centralized control unit (60) for centralized control on the air conditioning units (20, 20) and each of the air conditioning units (20, 20) so as to be capable of data transmission,
- wherein each internal/external transmission line (10B) and the integrated transmission line (10A) are connected to the outdoor units (30), and are connected to each other by transmission relay means (25) capable of separating data transmission between the transmission lines (10A, 10B), and
- the transmission relay means (25) includes:
- a switching hub (31) for daisy-chain connecting the integrated transmission line (10A) between the air conditioning units (20, 20);
- and a gateway (32) connected to the switching hub (31) and being capable of separating data transmission between the transmission lines (10A, 10B).
