For refrigerant with low (below 1K), or no glide, the capacity shall be assumed to vary directly with the temperature difference between the entering air and dew point evaporating temperature i.e: Required capacity = Nominal capacity wet x Required DT1/Standard DT1.Refrigerant factorRefrigerantR 404A/R 507R 22R 134aSC 1 SC 2 SC 3 SC 41 1 1 10,95 0,95 0,95 0,950,93 0,91 0,85Fin material factorAluminium finCoated aluminium finCopper fin10,971,03EXAMPLEGiven: Required capacity Air inlet temperature Evaporating temperature Refrigerant Coil with coated fins solution: DT1 = tA1 - te = (+2)-(-8) = 10KQ = 6000 W tA1 = +2 °C te = -8 °C R 22
