Ammonia Refrigeration – How It Differs
"How does ammonia refrigeration work?" Yes, it is different from refrigeration and air-conditioning using halocarbon refrigerants. But there are a lot of similarities also. So let’s start with some basics – a short review of vapor-compression refrigeration, native to all refrigerants. I’m going to leave out any discussion of ammonia/water absorption (heat-driven) cycles and limit this discussion to cycles involving vapor-compression.
The Bare Bones Basics
Every vapor-compression refrigeration system or unit ever built will have at least one each of these four components:
compressor
condenser
expansion device
evaporator
Figure 1 illustrates these components and their relative placement with one another.

The line numbers denote:
Hot gas (high pressure, high temperature)
Liquid (high pressure, warm temperature)
Liquid + vapor (low pressure, cold temperature)
Vapor (low pressure, cold temperature + ~10 ºF superheat)
