Why the refrigerant after the throttle into the evaporator must be wet steam?
A large number of absorption of heat, liquid refrigerant evaporates, the formation of gaseous, evaporator end should always be dry steam, liquid refrigerant into the compressor, will cause liquid blow, the compressor will be hurt.
Liquid refrigerant throttling into the evaporator due to reduced pressure, the refrigerant will phase change from liquid to gaseous, in the throttle can not suddenly all become gaseous, it is certainly wet steam, in the process
