1. Introduction
1.1 DAIKIN Building Air-conditioning Control System (D-BACS) Overview
D-BACS is a building air-conditioning control system built upon Daikin's unique high-speed multiplexed-transmission
technology. D-BACS can integrate and centrally control various air-conditioners. With Daikin’s VRV system at the center
various Daikin air-conditioning units, such as total heat exchangers, SkyAir, room air-conditioners, package air-conditioners,
and screw chillers can be integrated into the system. D-BACS can be also combined with other third-party building facilities,
such as ventilation air blowers, pumps, and illuminations.
D-BACS can mainly control operations such as:
1. Starting/Stopping equipment operation
2. Setting temperatures
3. Setting air volume for indoor unit fans in VRV system and total heat exchanger
4. Switching of cooling and heating
5. Displaying abnormalities
1.2 Advantages of D-BACS over Automatic Control by Central System
To enable automatic control in a central system, a capacity control and remote control must be designed carefully for
each different third-party air-conditioner, thus requiring a special system engineer (SE).
