Compressor
The compressor, its clutch and pulley form a removable assembly. The compressor compresses the low-pressure R134a refrigerant gas to high pressure and allows the refrigerant to flow in the system.
Electromagnetic Clutch
Allows engagement and disengagement of the compressor depending on system requirements. The coupling comprises two main parts: the stationary induction coil (continuous induction field) and the rotor. The induction coil is fitted directly onto the compressor. The grooved pulley is fitted to the tapered end of the crankshaft. The current transmitted to the coil creates a magnetic field, and the disc is magnetically pulled against the pulley. The compressor starts running. When the current is stopped, the rotor is demagnetised and the mechanical coupling is broken.
When changing one of the following parts: evaporator, condenser, dryer, compressor or regulator, it is necessary to drain the system, taking the precautions stated in the refilling and maintenance section.
Condenser
The condenser receives high pressure, high temperature refrigerant gas from the compressor and changes it into high pressure pre-cooled liquid. It is designed to withstand variations in temperature between the hot refrigerant in gas form and the cold air outside. As the refrigerant cools, the gas turns to liquid. This cooling is achieved by exposing it to a cold air flow (vehicle speed, motor fan). The refrigerant temperature in the condenser varies between 49 °C and 77 °C for pressures of 10.5 bar to 21 bar.
