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 the generation and transmission of electrical energy throughout the country. EGAT is also responsible for the sale of electricity. Electrical devices are tested in the company’s own laboratory in accordance with Thai standards.
The building’s HVAC system consists of a total of three water-cooled chillers controlled by an OPEN 810/5. In addition, the fresh air supply to the laboratories is ensured by a fresh air system. This fresh air system is controlled by an OPEN 600/5 so that the outside air supply can be optimally adjusted to the conditions in each room.
Furthermore, the laboratory rooms were equipped with 21 FCU controllers and thermostats. A particular challenge in this project was to integrate humidity control in conjunction with the appropriate air pressure in the laboratories in order to achieve the perfect indoor climate conditions.
The entire building is controlled by two tablet PCs. All system data can be accessed at any time via the OPENview web server. This allows technicians to access the systems at any time, even remotely.
Thanks to the comprehensive use of BACnet and Modbus, all subsystems used can communicate with each other smoothly and without interference.
