–Condenser:
The condenser is composed of flat horizontal aluminium tubes. The pipes are divided by the vanes in order to
increase the air heat exchange and therefore cool the refrigerant fluid to produce condensation.

2Dehydration canister
–Dehydrator reservoir:
The dehydrator reservoir is used to:
●Check the condition of the refrigerant.
●Absorb the variations in volume (expansion bottle principle).
●Filter impurities.
●Absorb moisture (water in the circuit).
–Air conditioning unit:
This unit acts as an air mixing box. It is equipped with a system of flaps which allow the air to be directed in
accordance with the requirements of the occupants whilst simultaneously allowing the temperature of the air
entering the passenger compartment to be modified by mixing hot and cold air.
–Thermostatic expansion valve: (see figure below)
This thermostatic-type expansion valve is used to check refrigerant expansion. It is located at the evaporator inlet.
–Evaporator: (see figure below)
●The evaporator is a heat exchanger which enables the air entering the passenger compartment to be cooled.
Note: Condensation of the air may occur thereby causing normal drops of water to form under the body.
