| The liquid refrigerant evaporates in the tubes of the
evaporator. The latent heat of evaporation is taken from the air
streaming past the evaporator fins. The air cools. The
refrigerant evaporates and is drawn into the air conditioning
system compressor carrying with it the heat it has absorbed. |
| A restrictor or an expansion valve allows a defined quantity
of refrigerant to flow to the evaporator. In systems with an
expansion valve, the flow is regulated such that only gaseous
refrigerant exits the evaporator. |
