REFRIGERANT CHARGING GUIDE - X TYPE MODELS Unit Refrigerant Charge (kg/Circuit) The following information can be used to estimate the refrigerant quantity required in a typical split system installation. The following table shows the refrigerant charge / circuit for the indoor and outdoor units.

Precision Air Conditioning -DF Design Data - Air & Water Cooled Models REFRIGERANT PIPE SIZING GUIDE - X TYPE MODELS Liquid Line Refrigerant Charge (kg/m) IMPORTANT To Calculate the Liquid Line Refrigerant Charge (kg) To Calculate the System Refrigerant Charge (kg) The following table shows the refrigerant charge / metre for the liquid line, using R407C and assuming liquid line temperature of 40°C. Liquid Line (m) kg/m 3/8” 0.05 1/2” 0.11 5/8” 0.16 3/4” 0.24 7/8” 0.34 The pipe sizes/refrigerant charges quoted are for guidance only. It is the responsibility of the installing contractor/site engineer to check the pipe sizes/refrigerant charge is correct for each system installation and application. Split systems may require additional oil which should be added to the low side of each compressor. Design should be in accordance with accepted refrigeration practice to ensure good oil return to the compressor(s) under all normal operating conditions. The liquid line refrigerant charge can be calculated using the following equation: LR = L x m Where: LR = Total Liquid Line Refrigerant charge (kg) L = Length of Interconnecting pipework (metres) m = Liquid Line Refrigerant charge / metre. Refer to Liquid Line Refrigerant Charge (kg/m) in this section The system refrigerant charge can be calculated using the following equation: SR = LR + IR + OR Where: SR = Total System Refrigerant charge (kg) LR = Total Liquid Line Refrigerant charge. (As calculated from above) IR = Indoor Unit Refrigerant Charge. Refer to Unit Refrigerant Charge (kg/Circuit) in this section OR = Outdoor Unit Refrigerant Charge. Refer to Unit Refrigerant Charge (kg/Circuit) in this section Example Indoor Unit Model Ref. = DF25X2-EZ (Tandem Set) Outdoor Unit Model Ref. = C45-H Condenser Interconnecting Pipework = 10 metres Selecting The Liquid Line Size From the Liquid Line Refrigerant Charge (kg/m) table in this section, the liquid line size given for pipework length of 10 metres is: Liquid Line Size = 5/8” Liquid Line Refrigerant Charge LR = L x m Where: L = 10 metres m = 0.16 kg/m LR = 10 x 0.16 Liquid Line Charge = 1.6 kg System Refrigerant Charge SR = LR + IR + OR Where: LR = 1.6 kg. (As calculated from above) IR = 4.1 kg OR = 6.1 kg SR = 1.6 + 4.1 + 5.2 System Refrigerant Charge = 11.8 kg / Circuit Precision Air Conditioning 41 Technical Manual : 6259014 v1.3.0 02_2013 AIR & WATER COOLED
