Technical Data For Air-Conditioning System With R1234YF And Refrigerant Oil SP-A2
Information
- The allocation of refrigerant to the vehicle is controlled via the additional equipment number (KK1 and KK3).
- The refrigerant quantity of the relevant refrigerant is controlled via the additional equipment number (9M3 = with heat pump).
| Air conditioning | Refrigerant quantity -R1234yf | Filling capacity of refrigerant oil SP-A2 |
|---|---|---|
| Climate control (without heat pump) | 930 g | 160 cm3 +/- 10 cm3 |
| Climate control (with heat pump/addition equipment number 9M3) | 980 g | 160 cm3 +/- 10 cm3 |
| General pressure values | bar (abs.) |
|---|---|
| High-pressure cut-off | 31 |
| Low-pressure cut-off at ambient temperature > 2 °C | 3 |
| Pressure relief valve purge pressure | 35 |
The following table is used to determine the refrigerant oil quantity after replacing components or following refrigerant loss due to damage to the refrigerant circuit.
The Min column is relevant for replacing components and/or slow loss of refrigerant/refrigerant oil (e.g. stone damage).
The Max column is relevant for sudden loss of refrigerant/refrigerant oil (e.g. after an accident).
| Refrigerant oil distribution in the circuit | Min - approx. cm3 | Max - approx. cm3 |
|---|---|---|
| Compressor | 40 | 50 |
| Condenser (for 2 condensers, the value is 30 cm3 /40 cm3 ) | 15 | 20 |
| Evaporator | 20 | 30 |
| Dryer | 10 | 10 |
| Chiller | 15 | 30 |
| Circulating oil quantity in the refrigerant circuit | 45 | 50 |
