The project consists of replacing existing Chillers with two (2) 900 Ton VFD Chillers together with necessary related work and equipment. New 900 Ton Variable Speed Chillers is designed to operate to 200 Ton during minimal load. Scope of work includes:
• Replace existing Plate and Frame Heat Exchanger with expanded capacity designed to use during winter months
• Replace 4160 Volt Unit Substation and Transformers with 480 Volt Unit Substation and Transformers to match new VFD Chiller requirement. Provision of redundancy to 480 Volt Transformer
• Design of BacNet DDC Controller for secondary loop to accommodate increased demand in chilled water system
• Design for required temporary power
• Design to minimize shutdown of chillers
