(Expansion Valve System)
1)High pressure side
Low pressure R134a vapor entering the compressor is compressed to become high pressure/temperature R134a vapor. This is then circulated along with lubricant oil to the condenser. As the high pressure/temperature vapor travels through the condenser, heat is released to the cooler ambient air passing over the condenser tubes condensing the vapor into a liquid. This high pressure/temperature liquid then travels through the filter drier onto the expansion valve where a small variable orifice provides a restriction against which compressor pushes.
 
2) pressure side
Suction from the compressor pulls the high pressure/temperature liquid R134a through small variable orifice of the TX valve and into the low-pressure side of the A/C system.
The R134a is now under low pressure/temperature vapor where heat from the cabin being blown over the evaporator coil surface is absorbed into the colder low pressure refrigerant The R134a is then pulled through the evaporator and into the
compressor.
The A/C cycle begins again as the R134a vapor is compressed and discharged under pressure.
3)Heat transfer
R134a in the LOW-PRESSURE side is COLD and can absorb large quantities of heat from the air moving over the evaporator.
R134a in HIGH-PRESSURE side is HOT and the cooler ambient air moving over the condenser can absorb the heat from it.
 
Summary
- When the R134a pressure is low, the R134a temperature is low.
- When the R134a pressure is high, the R134a temperature is high.
