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