5 Threats to Chiller Efficiency - Facilities Management Insights

Apr 01, 2003· Most new, high-efficiency centrifugal chillers carry a full-load efficiency rating of approximately 0.50 kW per ton. If that chiller is well maintained, in five years it can be expected to have a full-load efficiency of 0.55-0.60 kW per ton. If maintenance has been ignored for that same chiller, it would not be surprising to find that the full

surging centrifugal chiller, lowering condenser water temp …

Dec 14, 2005· Chillers are more prone to surge at lower loads, as the velocity of the refrigerant leaving the compressor is slower, and the pressure developed in the diffuser is less that the saturated condenser pressure resulting in surge. You can also increase the chilled water leaving temperature to reduce lift, and help with any icing problem you may have.
