[Utility Outage] Scheduled HVAC Outage - 08/26/2013 10:30

[Carroll W. Jones]

The following HVAC Outage has been Confirmed:

Outage:      JCI Control System Interface with Test Lab Chillers and Pumps Testing
Proposed By: Carroll W. Jones
Start Time:  08/26/2013 10:30
End Time:    08/27/2013 17:00
Description: Work will continue into Tuesday.  The Chiller 58-CH-4 failure sequence did not work properly and must be troubleshot and corrected.  Testing is still limited to impacting est Lab North Addition (HDICE and adjacent area), the EEL Building, and the Accelerator Glycol Loop until all functions are tested successfully. 

Once the majority of sequences are successfully tested with the current cooling loads, the chilled water system will be reconfigured with all loads (adding CEBAF Center F-Wing, TLA, and Test Lab Highbay loads) to complete final testing of the system.

For additional information or clarification, please contact me at 757-876-1778. 

_____________________________________________________________________________

JCI has completed interfacing with existing Test Lab chillers and pumps.  The controls will be tested in automatic this morning (8-26-13).  The Test Lab basement is currently supporting Test Lab North Addition (HDICE and adjacent area), the EEL Building, and the Accelerator Glycol Loop.  Chillers will be stopped and started.  Cooling loads should not be significantly impacted during testing.  The control system should react as required to maintain site conditions and efforts will be taken to restore systems if the new controls do not respond as desired. 

Once the majority of sequences are successfully tested with the current cooling loads, the chilled water system will be reconfigured with all loads (adding CEBAF Center F-Wing, TLA, and Test Lab Highbay loads) to complete final testing of the system.

For additional information or clarification, please contact me at 757-876-1778.

Sincerely,

Carroll W. Jones
