CONDENSER OPERATION
The high-pressure, high-heat gas travels through the condenser, where the heat
is dissipated by the condenser fan drawing cooler air over the condenser
tubing. This changes the gas into a high-pressure, warm liquid that then
enters the high-side filter drier. 
SEALED SYSTEM CAPILLARY TUBE
The warm liquid refrigerant travels through the capillary tube soldered to the suction line. The two tubes soldered together to create the heat exchanger. As the warm liquid refrigerant travels through the capillary tube, it gives up heat to the cool refrigerant gas in the suction line, which drops the pressure and changes the refrigerant into a low-pressure, cool liquid before it enters the evaporator.
FILTER DRIER OPERATION
The high-pressure, warm liquid travels through the high-side filter drier. The drier removes moisture from the refrigerant before it enters the capillary tube.
EVAPORATOR OPERATION
As the low-pressure, cool liquid refrigerant enters the evaporator, it vaporizes. This vaporization is caused by the dramatic pressure change from the refrigerant entering the larger diameter evaporator tubing from the smaller diameter capillary tubing. The vapor travels through the evaporator, absorbing heat from the compartment and gradually converting into a cool gas. This cool gas then enters the suction line.
SUCTION LINE
Cool gas travels through the suction line soldered to the capillary tube. The two tubes soldered together create the heat exchanger. As the cool refrigerant gas travels through the suction line, it absorbs heat from the warm liquid refrigerant traveling through the capillary tube, turning it into a lukewarm gas. This reduces the chance of liquid refrigerant entering the compressor. The lukewarm refrigerant gas then returns to the compressor, where the process starts over.
