Dear All,

I need assistance with the following information:

I am looking after a cold store with 4 screw type ammonia compressors - 2 for chiller / 2 for freezer ops.

I will start by the basics - can any one tell me some good reading on these systems?

I need to start by learning the basic refrigeration principles - go ahead and dive into the current system and also understand what terms like
Capacity: 325kW at SST -35 dC means
bKW: 175kW at SST -35 dC means,

Difference between single stage screw and compound two stage screw.

Looking forward to your reply?

Also, what is the minimum temperature we can achieve using this system? what data do I need to calculate total load for the room!
