Refrigerant circulation
The evaporator extracts heat from the process fluid, caus-
1
ing the refrigerant to vaporize (evaporate) into a gas.
2
Vaporized refrigerant travels to the compressor, where the
low pressure vapor is compressed into a high-pressure,
high-temperature vapor.
3
The high pressure vapor travels from the compressor
through the condenser, where the fan cools and condenses
the vapor into a high-temperature, high-pressure liquid.
4
High-pressure, high-temperature liquid is metered back to
the evaporator by the expansion valve (TXV), changing it
to a low-pressure, low-temperature liquid.
