In June of 2014 ETC, an Energy Efficiency Engineering firm located in Salt Lake City, Utah; coordinated with BD Medical to have Emerging Energy Services to conduct a paid demonstration on one of their chillers located in Salt Lake City, Utah. This location is a manufacturing facility which manufacturers medical devices.

The chiller designated for the demonstration was a 2006 Trane water cooled RTHD screw chiller used for comfort cooling needs. BD Medical purchased this chiller used in 2012. The facilities personal did a thorough citric acid cleaning of both the Evaporator and Condensing tubes when it was installed. BD Medical had the
compressor replaced due to metal filings found in the oil during installation. This chiller is maintained by the facilities personnel at BD and all required PM’s have been done.

The hook up of the ClimaCheck took approximately 1 hour. The facilities personnel did assist with the hook up of the CT Clamps and power connection. All the temperature sensors and pressure transducers were hooked by Joel Klobas of Emerging Energy Solutions. After spending about an hour to fine tune the ClimaCheck, we started to see an issue with the evaporator, KW per Ton and the capacity. You will see from the data collected and comparing it to the nominal data provided from Trane and BD Medical that this chiller is experiencing issues with the evaporator. Due to the issues in the evaporator we could only compare the nominal data at 100%.
