Application Condensing Pressure Regulation and Liquid Duty -
Nominal Capacities (kW)
24
Nominal capacities at +38°C condensing temperature, +4°C
evaporating temperature and 0.35 bar pressure drop.
Multiply above nominal capacities by following factors
to obtain capacities at different pressure drops:
∆P, bar 0. 5 0.20 0.35
Correction factor 0.65 0.76 .00
