Volkswagen Polo Service & Repair Manual: A/C System Operation
| The temperature in the passenger compartment depends on the
amount of heat radiated through the windows and conducted by the
metal parts of the body. In hot weather it is possible to
achieve a more comfortable temperature for the passengers by
pumping off some of the heat. |
| As heat spreads into cooler areas, the passenger compartment
is equipped with a unit for generating low temperatures. In the
unit, refrigerant is constantly evaporated. The heat required
for this is extracted from the air flowing through the
evaporator. |
| After absorbing heat, the refrigerant is pumped off through
the compressor. The action of the A/C compressor increases the
heat content and temperature of the refrigerant. Its temperature
is then substantially higher than that of the surrounding air. |
| The warm refrigerant flows to the condenser. There, the
refrigerant dissipates its heat through the condenser to the
surrounding air due to the temperature difference between the
refrigerant and air. |
| The refrigerant thus acts as a heat transfer medium. As it
is to be reused, the refrigerant is returned to the evaporator. |
| For this reason all air conditioning systems are based on
the refrigerant circulation principle. There are however
differences in the combination of aggregates. |
