The Borneo Convention Centre Kuching (BCCK) is located in Kuching, Sarawak, East Malaysia. It is the first dedicated convention and exhibition centre in Borneo. PPES Works (Sarawak) Sdn Bhd constructed this project for the Sarawak State Government, with KTA (Sarawak) Sdn Bhd as the M&E consultant and Mulpha Engineering & Construction Sdn Bhd as the HVAC contractor. Located on a 6 hectare riverfront site in the city of Kuching, construction began in June 2006 with estimated cost of about RM200 million. The building has a gross floor area of 36,500 m2 and sub-divided into a variety of sizes and configurations for plenary sessions, exhibitions and banquets. Largest pillar free exhibition space of 2,500 m2.
DB multiple screw chiller was the best choice for this application because our chillers will operate to meet the various cooling loads for different events held in the convention center. Our equipment was able to achieve much lower energy consumption (kW/RT) because of the strong efficiency of our compressors operating at part load (NPLV value at 0.577). As is typical of most comfort cooling applications the chillers do not need to load to full load constantly, but will alternate between full load and some degree of part load during the course of any day. The DB chillers in BCCK have an operating range from a minimum of 40 tons to a maximum 900 tons. The screw compressors used in these chillers utilize stepless loading and unloading that is possible because of our use of a dependable slide valve mechanism.
DB’s user friendly Vision2020i controller is designed to ensure smooth control of the chiller which, in turn, helps to ensure that the chiller is operating as per designed/required settings. Its ability to store and record the operating data will help technicians to easily troubleshoot any alarm of the chiller. At BCCK DB’s Vision 2020i controller interfaces with the Building Management System (BMS) using standard open communication MODBUS protocols.
