How Does a Ammonia Refrigeration System Work

In the refrigerant cycle, ammonia gas undergoes compression through the application of the compressor. This causes the gas to heat up under pressurization. The gas moves into the condenser where heat is dissipated in the coils. This condenses the ammonia, changing it into liquid form, but still at high pressure.

Is ammonia still used in refrigeration?

Ammonia, frequently used commercially in large freezing and refrigeration plants is also called “anhydrous ammonia” because it contains almost no water (it is 99.98% pure). … Ammonia is a 3-10% more efficient refrigerant than CFCs, so an ammonia-based system requires less electricity, resulting in lower operating costs.
