>>> sanhuaclimate.com 152 SELECTION FORMULAS Filter driers for liquid line are manufactured in compliance with ARI Standard 710. Maximum flow rate of liquid refrigerant at a differential pressure of 0,07bar (1psi) is indicated by kW (ton) which is based on the temperature of liquid refrigerant 30°C (86°F), the evaporating temperature of -15°C (5°F) and the following mass flow: • 0,40 kg/min/kW (3.1 lb/min/ton) R134a • 0,53 kg/min/kW (4.1 lb/min/ton) R404A, R507A • 0,39 kg/min/kW (3.0 lb/min/ton) R22, R407C • 0,36 kg/min/kW (2.8 lb/min/ton) R410A Note: Data on water absorption is based on the following EPD (method: ASHRAE Standard 63.1): • 60ppm R22 • 50ppm R134a • 50ppm R404A • 50ppm R407C • 50ppm R410A • 50ppm R507A SANHUA PRODUCTCATALOGUE HTG SERIES Filter DrierswithReplaceable Core SUCTION LINE FILTER-DRIERS: Any pressure loss in the suction line also reduces system capacity significantly. Obtaining a low pressure drop is particularly important for energy savings on all the air conditioning and refrigeration systems. Therefore, suction line filter-driers should be sized generously on these systems. Sanhua suggests that the pressure drop across it should not exceed the values given in the table below (table 4: DP limits in metric units; table 5: DP limits in imperial units) Suction Line Filter Drier Maximum Recommended Pressure Drop (bar) System Evaporator Saturated Suction Temperature 4) (°C) Permanent Installation Temporary Installation Refrigerant R22; R404A; R407C; R410A, R507 R134a R22; R404A; R407C; R410A, R507 R134a Air conditioning 4 0,21 0,14 0,56 0,42 Commercial -7 0,14 0,105 0,28 0,21 Low temperature -29 0,07 0,035 0,14 0,07 Suction Line Filter Drier Maximum Recommended Pressure Drop (psi) System Evaporator Saturated Suction Temperature 5) (°F) Permanent Installation Temporary Installation Refrigerant R22; R404A; R407C; R410A, R507 R134a R22; R404A; R407C; R410A, R507 R134a Air conditioning 40 3 2 8 6 Commercial 20 2 1,5 4 3 Low temperature -20 1 0,5 2 1 Table 5 Table 4
