Note: Approach temperatures shown are the mathematical difference between the chiller leaving water temperature and
the corresponding saturated refrigerant temperature of same circuit. When one compressor is operational the approach
value will be similar to those values found on single compressor models. However when both compressors are
operating, the upstream compressor circuits approach will be the mathematical difference of the upstream chillers
refrigerant temperature and the leaving water temperature after the down stream chillers circuit. Therefore the approach
of the upstream circuit will be a negative number in many instances, when both compressors are operating.
