Q1: Is the 30th edition of Ballaney very different from the 29th?
A: Not really. The 30th edition updated the refrigerant sections (added R-290, R-32 replacements for R-22). If you are studying for a 2025 exam, get the 30th. For general knowledge, the 28th is fine. Refrigeration And Air Conditioning By P.l. Ballaney Pdf Free
