Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. R407F Pressure Enthalpy Chart. Checking pipe sizing will confirm that capacity and efficient oil return are not being negatively affected. Vapor Density (bp, lb./ft ^ 3) 0.342 Heat of Vaporization (bp, BTU/lb.) It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. R407A, R407F, R448A and R449A have other density and mass flow than R404A/R507. The density is 1.52 lb/ft3. Download TDS (613 KB) | Download MSDS .

Ces trois gaz ont des températures d'évaporation très proches ce qui fait que le glide ou "glissement de température" est généralement considéré comme négligeable. The condensing unit was using a reciprocating compressor with POE 32 oil and a refrigerant charge of around 3.8 kg, adjusted based on liquid density. %���� 2 Table 1 R-507 Saturation Properties—Temperature Table Temp Pressure (kPa) Density (kg/m 3) Volume (m /kg) Enthalpy (kJ/kg) Entropy (kJ/K-kg) (°C) Liquid Vapor Liquid Vapor Liquid Vapor Liquid Latent Vapor Liquid Vapor–100 3.1 3.1 1471.0 0.215 0.0007 4.659 77.3 225.8 303.1 0.4469 1.7510 <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Chlorine is not present in -452A and RR -448A/R-449A and consequently, these refrigerants have zero Ozone Depletion Potential (ODP) . 1. 404A’s reign however was short lived. The same is true of saturated vaporat40°F. replacement for the HFC’s are R134a, R404A, R407A, R410A, R22, and hydrocarbons (propane and butane) and ammonia.
