Alco Controls Capacity Data for other than Nominal Operating Conditions Nominal capacities at +38°C condensing temperature (+38°C bubble point or +43°C dew point for R407C), +4°C evaporating temperature (saturated temperatures / dew point) and 1 K liquid subcooling at the inlet of the expansion valve. Correction factor for other evaporating temperatures than nominal: Q n = Q o x K t Q n : Nominal capacity K t : Correction factor for a pressure drop corresponding 1 K saturation temperature Q o : Required cooling capacity Correction Factors Correction factor K t Refrigerant Condensing Evaporating temperature °C Temperature °C 10 0 -10 -20 -30 -40 -50 25 1,29 1,31 1,33 1,36 1,40 1,44 1,49 30 1,16 1,17 1,20 1,23 1,27 1,31 1,36 R 22 35 1,05 1,07 1,09 1,11 1,13 1,17 1,23 R 407 40 0,95 0,96 0,98 1,00 1,03 1,07 1,12 45 0,87 0,88 0,90 0,92 0,95 0,99 1,04 50 0,81 0,83 0,85 0,87 0,89 0,93 0,99 Correction factor K t Refrigerant Condensing Evaporating temperature °C Temperature °C 10 0 -10 -20 -30 25 1,31 1,36 1,39 1,43 1,50 30 1,18 1,21 1,24 1,28 1,35 R 134a 35 1,06 1,08 1,11 1,15 1,21 40 0,95 0,98 1,01 1,05 1,10 45 0,86 0,88 0,92 0,95 1,02 50 0,80 0,81 0,85 0,89 0,97 Correction factor K t Refrigerant Condensing Evaporating temperature °C Temperature °C 10 0 -10 -20 -30 -40 -50 25 1,22 1,25 1,30 1,33 1,43 1,53 1,63 30 1,12 1,15 1,20 1,26 1,32 1,42 1,54 R 404A 35 1,03 1,06 1,11 1,16 1,24 1,34 1,46 R 507 40 0,95 0,99 1,04 1,09 1,17 1,28 1,41 45 0,90 0,92 0,97 1,03 1,14 1,26 1,39 50 0,86 0,89 0,93 1,00 1,13 1,26 1,39 146 A2.5.1/0810/E
