Retrofitting R11 to R123
1. While retrofitting from R11 to R123 float valve/orifice size is to be changed. Whether it is to be undersized/ over sized / maintained the same?
2. To improve the performance number of tubes is to be increased and impeller speed is to be increased. By how much % should each of them be increased?
