Waterfront Hilton

Waterfront Hilton

We started theHVAC investigation/retrofitting process in April 2008. We installed a new HVAC Trane chiller flat plate heat exchanger for free cooling for phase 1 of the process. A wet side economizer was utilized along with condenser water sensors to monitor temperature and allow control of VFDs for cooling tower fans and pumps. We provided an interface panel to Metasys NAE front end to allow chiller parameters to be remotely monitored and controlled via a graphical front end. Since April, the newly designed and maintained plant has saved Hilton over $300,000.

Sheraton Universal

Installed 2 new HVAC Trane chillers. We upgraded the BAS to allow integration to the central chiller plant controls. We installed DX9100 controllers for peripheral interface and further control using Johnson’s Metasys system. Set up internet access for remote monitoring and control to increase flexibility and control options. We are maintaining the plant through continuous commissioning. Based on the new equipment and monitoring Sheraton is a much more efficient operation.
