Reducing Refrigerant Loss from a Purge Unit on a R123 Chiller

What should be done to reduce refrigerant loss from a purge unit on a R123 chiller?

What actions can be taken to minimize the loss of refrigerant from a purge unit on a R123 chiller?

Answer:

Reducing refrigerant loss from a purge unit on a R123 chiller can be achieved by a combination of testing for leaks and making necessary repairs, sealing the discharge line, and routing purged refrigerant back into the system or a recovery unit.

When trying to reduce refrigerant loss from a purge unit on a R123 chiller, it is essential to follow certain steps to ensure the efficiency and proper functioning of the system. The options provided in the question offer potential solutions to address this issue.

Firstly, conducting a thorough leak test of the chiller is crucial. This involves identifying any leaks in the system and promptly repairing them. By sealing off these leaks, the amount of refrigerant lost through the purge unit can be significantly reduced.

Secondly, ensuring that the purge unit discharge line is properly sealed is important. Any gaps or leaks in the discharge line can contribute to refrigerant loss, so it is essential to address any issues in this area.

Lastly, determining where the purged refrigerant should be directed is key. The options of piping the purge unit back into the low side or into a recovery unit provide different approaches to managing the recovered refrigerant effectively. The best choice between these options would depend on the specific setup and requirements of the chiller system.

By implementing these measures, the overall efficiency and sustainability of the R123 chiller can be enhanced, resulting in reduced refrigerant loss and improved performance.
