General information
Air conditioning is installed on certain models. It reduces the temperature of the incoming air and removes moisture from the air, which helps to quickly eliminate window fogging and increase comfort.
The cooling side of the system works similarly to a home refrigerator. Gaseous refrigerant is drawn into the compressor (belted) and then passes into the condenser mounted on the front of the radiator (where it loses heat and becomes liquid). The liquid refrigerant passes through the expansion valve to the evaporator where it changes from a high pressure liquid to a low pressure gas. This change is accompanied by a decrease in temperature, which causes the evaporator to cool. The refrigerant returns to the compressor and the cycle starts again.
The air drawn through the evaporator passes into the air distribution unit, where it mixes with the hot air passing through the heater core to reach the desired temperature in the vehicle interior.
The heating side of the system works as in models without air conditioning (see paragraph 9).
The air conditioning system is controlled by an electronic control unit that controls the electric fan (-ami) cooling, compressor and control lamp mounted on the front panel. For any problems with the system, contact your Peugeot/Citroen dealer.
Advice. Many auto parts stores sell disposable aerosols for recharging air conditioning systems. They typically contain refrigerant, compressor oil, leak sealant, and a system conditioner. Some also contain dye to help locate the leak.
Precautionary measures
In the presence of an air conditioner, when working with any part of the system, its elements and other nodes that require «autopsy» refrigerant circuit, special precautions must be observed. If for any reason you need «open» system, have it done by a Peugeot/Citroen dealer.
Attention! These products should be used according to the manufacturer's instructions. They do not eliminate the need for regular maintenance.
Attention! The air conditioning circuit contains liquid refrigerant. For these reasons, it is very dangerous to disconnect any part of the system without special knowledge and equipment.
The refrigerant is a potentially hazardous substance and should only be handled by specially trained personnel. If the refrigerant comes into contact with the skin, frostbite may occur.
It is not poisonous in itself, but when exposed to open fire (including a cigarette) produces poisonous gas. Uncontrolled discharge of refrigerant from a system is dangerous and a potential source of environmental damage.
