LOW DELTA-T SYNDROME SURVEYS

A low delta-T syndrome results in inefficient chillers, higher energy consumption of the chiller plant, and slow response to the indoor comfort needs.

The low delta-T syndrome exists in many chilled water systems and district cooling plants, which results in the degradation of the system overall energy performance.

Almost every chilled water system is affected by the low delta-T syndrome, in which the supply and return chilled water temperatures fall short of the design level, particularly at low loads. This results in inefficient chillers, higher energy consumption of the chiller plant, and slow response to the indoor comfort needs.

EMergy support the plant operators and building owners in operating a chilled water system that can resolve the low delta-T problem, and accommodate and minimize its impact on the energy performance.
