The basic cooling cycle is the same for both vapor-compression and absorption chillers. Both systems utilize a liquid refrigerant that changes phase to a gas within an evaporator which absorbs heat from the water to be cooled.

The refrigerant gas is then compressed to a higher pressure by a compressor or a generator, converted back into a liquid by rejecting heat through a condenser and then expanded to a low- pressure mixture of liquid and vapor that goes back to the evaporator section.  The cycle is repeated.
