The Compressor in a System

notes

suction temperature falls, and coil frosting or chiller freezing may occur. Since

the hot-gas-bypass valve is sized to pass a given quantity of refrigerant vapor at

 

a particular condensing–suction pressure difference, some means of

 

maintaining the condensing pressure within limits must be provided. Various

 

methods of controlling condensing pressure are discussed in the Refrigeration

 

System Components clinic.
