Customer wants a computer rack-mounted cooler system for his computers, which dissipate about 15kW of sensible heat. Door-mounted coolers on computer racks mostly use chilled water rather than fridge, and as there is no in-house (24-7) chilled water on tap for this project, it would mean sourcing a suitable smallish chiller unit. Well, two chiller units, with the second one in standby setup.
1) Has anyone installed this kind of system, in the range of 15-25kW chiller plant, serving rack-mounted coolers (FCUs, basically)?
2) Any suggestions/recs, as regards the chiller make or a rack/cooler+chiller package?
3) The water-type systems boast cheaper run-costs but I suspect that this being quite a smallish load, the install price for a duty-standby chiller set up is a chunk more than 3x 10kW Daikin DX systems. Anyone looked at this and have some comments?
