I am working on a cold store. It runs 2 Halls 4 cylinder compressors connected together in to a low presure reciever which subcools the refrigerant liquid and the evaperators are flooded. The system runs on R403b which is 57% by weight of R22. My question is the customer has some R22 can I put this into the system if I need to top it up?
