CAUTION!
1. Additional glycol beyond the recommendations will adversely
affect unit performance. The unit efficiency will be reduced and the
saturated evaporator temperature will be reduced. For some operating
conditions this effect can be significant.
2. If additional glycol is used, then use the actual % glycol to establish the
low refrigerant cutout set point.
3. The minimum low refrigerant cutout set point allowed is - 20.6°C.
This minimum is established by the solubility limits of the oil in the
refrigerant.
4. With glycol application, ensure that there is no fluctuation of brine
flow versus Order Write Up value, as a reduction of flow will adversely
affect unit performance and behaviour.
5. Tables above should not be interpreted as suggesting operating ability
or performance characteristics at all tabulated glycol percentages.
Full unit simulation is required for proper prediction of unit
performance for specific operating conditions. For information on
specific conditions, contact Trane.
