Provide 380 tons of cooling for a 66,000 sq ft building spread across four flours. 19 condensers at 380-415 volts connected to a refrigerant network of Ducted, Fresh Air Systems, and cassettes type fan coil units were selected to allow zone cooling to optimize energy efficiency whilst allowing fresh air introduction into production spaces. A Hisense central controller was incorporated to allow schedule program operation and system performance monitoring from a single device.
