True or False: Adding liquid refrigerant directly into the liquid receiver should be done with the compressor running.

• A. True
• B. False
• C. Only in emergencies
• D. It depends on the refrigerant

Answer: (B)

Adding liquid refrigerant directly into the liquid receiver should be done with the compressor off, making the statement false. This practice is essential for maintaining system safety and efficiency. By ensuring the compressor is not running during this process, it prevents the potential for liquid refrigerant returning to the compressor, which could cause damage. Additionally, when the compressor is off, the system can better accommodate the added refrigerant without causing pressure imbalances or other operational issues. Using a compressor that is on can lead to complications, such as excessive head pressure or even liquid slugging, which can harm the compressor. Therefore, the proper procedure requires that liquid refrigerant is added only when the compressor is not operating to ensure the protection and longevity of the refrigeration system.
