HI,

We currently have a large refrigeration unit for a chemical proces. It consists of 2 compressors a condensor with receiver. The refrigerant(R22) is pumped to an expander and flashvessel.
The refrigerant flashes for a large portion immediately in the flasvessel(-30C), because of the high temperature of the liquid refrigerant(40C).
The flashvessel is not big enough, because liquid droplets are carried to the compressor(BAD).

Is refrigerant sub cooling a good solution for this problem?
Are there package units to perform this sub cooling?

Thanks !
Michiel
