10. A/C and Safety System 10-3 A/C system A/C system 10.1 Cooling system 10.1.1 Warnings and precautions Warning! – Refrigerant-related work shall be carried out in a well-ventilated environment to avoid inhaling refrigerant vapors. You shall avoid inhaling A/C refrigerant R-134a (tetrafluoroethane) and lubricating oil vapors or mists. Contact with them can irritate your eyes, nose and throat. When recovering A/C refrigerant R-134a from the A/C system, use certified service equipment (R-134a regeneration equipment) that meets the requirements. In the event of an accidental discharge of the system, the work area must be ventilated before the service continues.

– It is necessary to disconnect the negative terminal of the battery before servicing the electrical system. Never perform welding or steam cleaning on or near the vehicles with A/C pipelines or assembly. Precautions for A/C refrigerants Warning! – Skin contact may cause frostbite. – Wear suitable goggles and protective gloves when working. Actions to avoid with A/C refrigerants Warning! – Do not store the refrigerant in places exposed to sunlight or sources of heat. – When filling, do not hold the refrigerant bottles upright and keep their valves facing down. – Do not expose the refrigerant bottle to frost and snow. – Do not drop the refrigerant bottle.

– Do not discharge the refrigerant directly into the atmosphere in any case. – Do not mix refrigerants such as R134a (tetrafluoroethane) and R12 (difluorodichloromethane). Precautions on compressor lubricating oil Warning! – It is necessary to use compressor lubricating oil of the specified type and brand, and the compressor lubricating oil of different types and brands must not be mixed, otherwise the compressor will be damaged. – Compressor lubricating oil is very easy to absorb water, so try to minimize the exposure time of the compressor lubricating oil to air as much as possible. Warning! – Never use water, corrosive solvents or flammable and explosive solvents to clean the A/C system.

10-4 A/C system 10. A/C and Safety System 4.2 Operating principle of system High pressure gas High pressure liquid Low pressure liquid Low pressure gas Cold air Evaporator Hot air in the vehicle Compressor Blower Expansion valve Condenser Dryer Outside air – When the A/C system is refrigerating, the compressor sucks the low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and the compressed refrigerant will be sent to the condenser.

In the condenser, the high temperature and high pressure gaseous refrigerant passes through the condenser to dissipate the heat, and is liquefied into the high temperature and high pressure liquid refrigerant. – The high-temperature and high-pressure liquid refrigerant passes through the drier reservoir and high- pressure pipeline, quickly flows through the expansion valve, and is then throttled via the throttle expansion valve, thus being transformed from liquid to gas following a rapid temperature and pressure decline. At last, it is sent to the evaporator through the liquid separator head.

– In the evaporator, the air blower draws the air in the vehicle into the surface of the evaporator, and the air exchanges heat with the low-temperature, low-pressure aerosol refrigerant through the evaporator fins. After absorbing the air heat in the vehicle, the low temperature, low pressure vaporous refrigerant is evaporated into the low temperature, low pressure gaseous refrigerant, and then sent to the low pressure side of the compressor through the pipe for the next cycle. – The cold air released by the heat exchange is sent into the vehicle by the blower to reduce the vehicle temperature.
