Converting R12 refrigerant circuits to R134a refrigerant circuits and repairing them (retrofitting) |
Note t
| The laws and regulations listed below are valid in the Federal Republic of Germany. Other or additional laws and regulations may apply in other countries. |
t
| Sources in other countries may be obtained from the responsible authorities. |
t
| Due to the environmental situation and the consequent legislation, refrigerant R12 is currently neither in production nor available. Refrigerant R134a was developed as a replacement for R12. |
t
| However, air conditioning systems developed and designed for refrigerant R12 cannot simply be charged with refrigerant R134a. To ensure trouble-free operation of the air conditioning system following a retrofit, various components of the refrigerant circuit must be replaced. |
