Which statement about strainers in refrigeration systems is false?

The statement that piping must be disconnected to clean the strainer is misleading, which makes it the false option. In many designs of strainers, especially those that incorporate a blow-off or cleaning port, it is possible to clean them without the need to disconnect the piping. This feature allows for maintenance to be performed more efficiently and can minimize system downtime.

Strainers play an essential role in refrigeration systems by preventing debris from entering the system, which can cause a variety of issues such as clogging and damage to sensitive components. They are critical for ensuring the longevity and proper functioning of the equipment. Additionally, by keeping contaminants out, strainers do indeed help extend the life of system components.

The assertion that strainers are only needed in large systems is not accurate, as the presence of debris can be a concern in systems of all sizes. Thus, all refrigeration systems can benefit from having strainers to maintain system integrity and performance.
