HACS without In-row cooling?

[BillP]

Hi, just a quick question, we are moving our server room into a preexisting room where the Air-con has already been put in place.
I am quite keen on the Thermal Containment system APC can provide to compliment their racks, however in all the examples I see they use in-row cooling. Is there a way I can just duct the air out and to an existing in-room aircon unit or is this frowned upon / not suggested?

6 - 8 racks, high density but not highly utilised.


Thanks

Anything is possible......

The roof sections of the HACS is a double layer lexan type material that can easily be cut to accommodate return air ducts.

A few things to consider.

1) Are you using a flooded type CRAC or raised floor construction with perforated tiles in front of your racks? Some raised floor designs cannot supply high volumes or air needed for High Density HACS systems.
2) Do you have enough overhead space for ducting?
3) Plan on using blanking panels for open U space in racks.
4) I could only imagine APC wouldn't warranty or support and performance issues with modifying and using the HACS in this manner.
5) Do you have any cooling redundancy? A failed single CRAC system can cause a HACS to overheat in a matter of minutes.

To get this to work you just have to visualize what a HACS system does, Evacuate Hot air without allowing it to mingle with cool air. Utilizing the proper return ducting and cooling supply you can get this to work. I'd get an Engineer involved to assist with the planning stage.
