Refrigerant circulation

HOW IT WORKS:

4 The liquid refrigerant leaves the accumulator, passing through the ther- mal expansion valve, where it expands and cools.

3 The high pressure vapor travels from the compressor through the condenser (where fans cool vapor into a liquid) and liquid is stored in the accumulator.

CHILLER

2 Vaporized refrigerant travels from evapora-

tor to the compressor, where the low pressure vapor is compressed into a high pressure vapor.

1 The evaporator extracts heat from the process fluid, caus-

ing the refrigerant to vaporize (evaporate) into a gas.

5 Cooled refrigerant is metered back into the exaporator for

the cycle to begin again.
