“Using smarter technologies, more brains and less money to wring more work from less delivered energy… is the largest, cheapest, safest, cleanest, fastest, most diverse, least visible, least understood and most neglected way to provide energy services.”

Evaluation Period

ESM™ units were installed in June 2008 to optimize the chillers. Each chiller also had a Profile Energy Logger installed to monitor the energy consumption of the compressors. The number of starts made by each compressor were monitored using a Squirrel Logger. Data was collected over a two week period as the ESM™ units alternated between OFF and ON modes. The energy savings shown below were achieved with no discernable impact on temperature.

 

Project Description

The Radisson SAS Hotel located in Media City, Dubai, UAE, is a seven-storey luxury facility with 246 guestrooms and 12 meeting rooms. The two York chillers responsible for cooling the West Tower of the hotel served as the target of this initial installation. Smartcool’s ESM™ with the Intelligent Interface Module was chosen for the installation, due to its ability to effectively and safely optimize the compressors in chillers.
