How an Ammonia Chiller Works

An ammonia chiller operates using the vapor-compression refrigeration cycle but utilizes ammonia (NH₃) as the refrigerant.

01

Refrigerant Compression

The ammonia compressor increases the pressure and temperature of ammonia vapor.
02

Heat Rejection

The hot ammonia gas enters the condenser where heat is removed and the refrigerant condenses into a liquid.
03

Expansion Process

The liquid ammonia passes through an expansion valve where pressure and temperature decrease.
04

Heat Absorption

Inside the evaporator, ammonia absorbs heat from process water or process fluids, producing chilled water or direct refrigeration.
05

Cooling Delivery

The cooled fluid is circulated to production equipment, cold rooms, storage facilities, or manufacturing processes.
06

Continuous Refrigeration Cycle

The refrigerant returns to the compressor and the cycle repeats continuously to maintain precise temperatures.

Because ammonia possesses excellent thermodynamic properties, the system achieves higher efficiency and reduced power consumption compared to many conventional refrigerants.
