Figure 4-5. Evaporator
Capillary Tube (& Heat Exchanger) (Figure 4-4)
The warm liquid refrigerant travels through the long skinny
capillary tube which is soldered to the suction line. (These
two tubes soldered together create the heat exchanger.)
As the warm liquid refrigerant travels through the capillary
tube it gives up heat to the cool refrigerant gas traveling
through the suction line and the pressure drops, so it is a
low-pressure/cool liquid before it enters the evaporator.
Evaporator (Figure 4-5)
As the low-pressure/cool liquid refrigerant enters the evap-
orator, it vaporizes. This is caused by a dramatic pressure
change which occurs when the refrigerant enters the larg-
er diameter evaporator tubing from the smaller diameter
capillary tubing. This vapor travels through the evaporator
absorbing heat from the compartment, gradually convert-
ing it to a cool gas. This cool gas then enters the suction
line.
Suction Line (& Heat Exchanger) (Figure 4-6)
The cool gas travels through the suction line which is sol-
dered to the capillary tube. (As mentioned earlier, these
two tubes soldered together create the heat exchanger.)
As this cool refrigerant gas travels through the suction line
it absorbs heat from the warm liquid refrigerant traveling
through the capillary tube, making it a luke warm gas. The
lukewarm refrigerant gas then returns to the compressor
where the process begins again.
