(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
(3) At high speed with nominal air flow.
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
Heat exchanger operating limits:
FWD:
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
*absolute service pressure: min 1 bar/max 11 bars
Evaporator Waterside
Table 37 – Recommended Low Evaporator Refrigerant Cutout (LRTC) and % Glycol for RTAF chillers size 090 to 245
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.
