What is the pressing issue with liquid refrigerant recovery?

The pressing issue with liquid refrigerant recovery is primarily that it may lead to system damage. When refrigerants are recovered in liquid form, there is a risk of introducing excess pressure into the recovery system if not managed properly. This high pressure can strain components of the refrigeration system, potentially resulting in damage. For instance, if liquid refrigerant is forced into the compressor instead of vapor, it can cause what is known as liquid slugging, which may severely damage the compressor.

Moreover, recovering refrigerants improperly can interfere with the normal operation and longevity of refrigeration components, leading to more costly repairs or replacements in the long run. Therefore, effective recovery practices and adhering to guidelines are essential in preventing such types of damage.
