In this age of interconnected global supply chains, stakeholders demand authentic carbon reduction results from companies. As the journey can be quite challenging, a chipmaker in Taiwan enlisted the help of Delta’s team of technology experts and consultants to migrate towards net zero. With a treasure trove of green technologies, Delta delivered its tailor-made Smart Chiller Energy Saving Solution to improve carbon metrics at the chipmaking plant.
In semiconductor plants, cleanrooms are critical facilities, where hundreds of chillers keep temperatures cool and constant. However, maintaining stable temperatures for quality manufacturing is highly energy-intensive. Chipmakers usually prioritize energy-saving in A/C systems, and are particularly focused on chillers to improve energy efficiency without adversely affecting yield rates.
In the chipmaker’s plant, the chiller water pump capacity was designed based on the system's maximum load. Running the pumps at full speed all the time wasted resources, leading to potential downtime and chiller surges. Furthermore, operators often added standby chillers to avoid affecting production capacity, resulting in chiller flow imbalances and increased energy consumption under an unstable system. 
Delta’s solution leverages variable frequency functions and integrated OT+IT information to upgrade energy efficiency in chiller water pumps.
The Delta Smart Chiller Energy Saving Solution harnesses a variable frequency feature to upgrade energy efficiency. Moreover, through data collection and integrated monitoring across different plants, clients can gain insights into the field devices — such as chiller inlet/outlet temperatures and flow conditions. This enables more comprehensive energy-saving strategies, achieving energy savings of 14 million kWh annually. Notably, the solution expenses were offset in only two years.
The Delta Smart Chiller Energy Saving Solution aims for efficient resource allocation and energy saving with its variable frequency capabilities. It utilizes the Temperature Controller DT Series and flow meters, which send signals to the PLC AH500 Series that controls the Fluid Industry Drive VP3000 Series. With these products, Delta’s solution ensures the variable flow of the chiller water pump, effectively facilitating energy savings. In addition, it calculates the optimal number of operating chillers, water pumps, and fans. This feature reduces idling and standby waste while enhancing system stability.
