Dear all,

Hello to every one, I am new in this forum and I am trying to learn ammonia refrigeration and its valves selection for evaporators.

To all respected members, I need your help, what is the Saturated suction temperature and how would i decide it.

I need to install a ammonia evaporator to maintain a room temperature at -20 degC and I have a liquid ammonia supply at -42 degC. So I need to know that what would be its evaporation temperature ?? What would be its SST ?? and also how would I select the valve station for this evaporator ??

Any help in this matter would be highly appreciable, looking forward for your help.

Thank you.
