Manage off cycle migration

R

Requirement

Evaluate the risk

Off -cycle refrigerant migration happens:  

•

 when the compressor is located at the coldest 

part of the installation, refrigerant vapor 
condenses in the compressor.

• 

or directly in liquid-phase by gravity.

When the compressor starts running again, the 
refrigerant diluted in the oil generates poor 
lubrication conditions. In extreme situations, 
this leads to liquid slugging that can damage 
compression parts.

Amount of liquid refrigerant in the compressors 
must not overpass the charge limit (refer to 
charge limit table in section “Manage superheat”).

Use the table below in relation with the system 
charge (refer to charge limit table in section 
“Manage superheat”) and the application to 

quickly define necessary safeties to implement 
and test to perform:

Non split

No test or additional safeties required

(Internal Non-Return Valve integrated)

• Crank Case Heater*

• Migration test

• External Non Return Valve

Split

Since each installation is unique, no test can fully evaluate off-cycle migration, therefore 

the following safeties are required:

• Crank Case Heater *

• Liquid Line Solenoid Valve**+ pump-down cycle***

• (Internal Non-Return Valve integrated)
