Energy supplier EGAT

The Electricity Generating Authority of Thailand, EGAT for short, is Thailand’s leading energy supplier. The state-owned company is responsible for electrical power generation and transmission for the entire country. In addition, EGAT is also responsible for electricity sales. In the in-house laboratory, electrical equipment is tested according to Thai standards.

The building’s HVAC system consists of a total of 3 water-cooled chillers controlled by an OPEN 810/5. In addition, the fresh air supply of the laboratories is ensured by a fresh air system. This fresh air system is controlled by an OPEN 600/5, so that the supply of fresh air can be optimally adjusted according to the conditions of the individual rooms.

In addition, the laboratory rooms were equipped with 21 FCU controllers and thermostats. A special challenge in this project was to integrate the humidity control in conjunction with the adapted air pressure in the laboratories in order to achieve the perfect indoor climate conditions.

The entire building is controlled by 2 tablet PCs. Through access via the OPENview web server, all system data can be called up at any time. This enables the technician to access the systems at any time, even remotely.

Due to the holistic use of BACnet and Modbus, all subsystems used can communicate with each other without any problems or interference.
