Notes on handling refrigerant R134a - AH83.30-N-0003-01A

Air conditioning with refrigerant R134a

The refrigerant R134a is colorless and odorless.

At normal temperatures it is neither toxic nor flammable, and will not explode in the air, no matter what its mixing ratio.

The R134a refrigerant may only be used in air conditioning systems for which R134a has been specifically approved.

The refrigerant R134a must not be mixed with other refrigerants (e.g. R12)

Scheme 71

The refrigerant R134a does not contain any chlorofluorocarbons (CFC). In contrast to other refrigerants (e.g. R12) it is not hazardous to the environment at normal temperatures. The refrigerant R134a does not damage the earth's ozone layer.

Despite these benefits, refrigerant R134a may only be extracted by experts with suitable extraction, recycling and filling equipment that includes integral disposal and reprocessing capabilities.

Procedure for a damaged or leaky air conditioning system - AH83.30-N-0004-01A

All models

The air conditioning system should never be operated if it is damaged or when there is evidence of refrigerant loss.

In the event that refrigerant is lost, lubrication can fail. This will lead to damage of the refrigerant compressor.

Evacuate damaged and/or leaking air conditioning refrigerant circuits as quickly as possible using extraction, processing and recharging equipment with integral disposal and reprocessing capabilities.

Protect air conditioning circuit and components from moisture when carrying out repair work - AH83.30-N-0005-01A

All models with air conditioning

Do not carry repair operations out on the air conditioning circuit in the open air during moist weather

Scheme 72

Moisture in the refrigerant circuit reduces the system's refrigeration output and leads to damage to the components. Acidification in the circuit caused by moisture decomposes the drier element installed (e.g. fluid reservoir, filter drier or desiccant cartridge) and thus damages the entire system.

After separating/unscrewing refrigerant lines, immediately seal off the connection openings so that they are airproof using suitable stop plugs (parts kit).

The drier element must be replaced every time the refrigeration circuit is opened.

Always store all spare components in a dry, sealed-off area. Do not remove stop plugs in new components until just before they are installed. Use special care when handling the fluid reservoir with its integral desiccant.

When a fluid reservoir is left open, the drier element quickly becomes saturated with moisture, rendering it useless.

Check drier element packaging for damage. Dispose of drier elements with damaged packaging.

Install the drier element no later than 20 minutes after opening the packaging.

Further protection against moisture is provided by carefully evacuating the air conditioning system following repair operations.

By generating vacuum in the system, the evacuation process removes any moisture that might have penetrated into the system.

Risk of explosion. Explosions may result when performing welding or soldering work on a closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant. - AS83.00-Z-0001-01A

Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been discharged.

Potential risks

Risk of explosion

When closed air conditioning systems (charged or empty) become heated, high pressures are produced that can ultimately cause the system to burst. For this reason, all welding and soldering operations on or near closed air conditioning systems are prohibited.

High pressure levels can combine with refrigerant vapors to produce a mixture that is potentially explosive when exposed to atmospheric air.

Risk of poisoning

Refrigerant can decompose when overheated. The resulting substances are toxic and should never be inhaled.

Risk of injury

Refrigerant vapors are heavier than air; this means that escaping gases pose a risk of suffocation for anyone in a work pit beneath the vehicle.

Contact with liquid refrigerant may cause chilblain-like damage to the skin (due to undercooling).

Safety instructions/precautions

1. All welding, brazing and soldering operations on sealed air conditioning systems and in their immediate vicinity are prohibited.
2. Never smoke when working with refrigerant, never expose refrigerant to open flames.
3. A piercing odor can indicate overheated refrigerant - never inhale these vapors. Leave closed rooms immediately and ventilate thoroughly.
4. All refrigerant must be evacuated from the entire air conditioning system prior to doing any repair work on the air conditioning circuit or components.
5. Because it poses a hazard to the atmosphere as well as to personal health and safety, discharging refrigerant directly into the air is prohibited.
6. Suitable evacuation, treatment and charging devices equipped with integral disposal and treatment facilities must be used for evacuating refrigerant.
7. Even after the system has been evacuated, residual pressure may still be present in the system when loosening couplings. Therefore, loosen the couplings carefully, so that the pressure can dissipate slowly.
8. Avoid all contact with liquid refrigerant.
9. Always wear safety glasses and protective gloves when working with refrigerant.

First aid measures

In case of eye contact

1. Immediately flush with plenty of running water and consult a physician.

In case of skin contact

1. Consult a physician immediately in case of frostbite.

In case of inhalation

1. of concentrated refrigerant, immediately take victim out into the fresh air and keep victim calm.
2. If the victim's breathing is shallow, or the individual has stopped breathing altogether, tilt the head back and administer artificial resuscitation. Call a physician.

In case of ingestion

1. Consult a physician immediately.

AIR CONDITIONING SYSTEM

Ventilation system, function - GF83.10-P-2000MCU

MODEL 451.3 /4

Scheme 77

The ventilation system prevents the windows from misting up and ensures that there is a uniform, pleasant temperature in the vehicle interior.

Function requirements

1. Circuit 15 On

The ventilation allows the following operating modes

1. Fresh air mode
2. Air recirculation mode (with code (I01) Air conditioning Plus)

The following components are actuated by the heater/AC operating unit

1. Blend air flap actuator (M16/8) (with code (I01) Air conditioning Plus)
2. Air recirculation flap actuator motor (M39)

(with code (I01) Air conditioning Plus)

Fresh air mode

The fresh air is drawn in through the air inlet in the front maintenance flap and passed on into the heater or air conditioner housing (with code (I01) Air conditioning Plus) via the pollen filter. Depending on the preselection via the air distribution rotary switch, the fresh air is passed on via the blend air flap into the vehicle interior through the air ducts and air outlets (arrows). On vehicles with code (I01) Air conditioning Plus, the blend air flap is actuated via the blend air flap actuator, which is actuated by the heater/AC operating unit depending on the following information

1. Specified temperature set on the temperature preselection slider switch
2. Interior temperature
3. Temperature on evaporator
4. Coolant temperature

On vehicles without code (I01) Air conditioning Plus, the blend air flap is adjusted mechanically by the temperature preselection slider switch in the heater/AC operating unit by means of a cable.

Depending on the actuation of the blend air flap, it opens or closes the air passage through the heater heat exchanger.

The blower switch (S98/1) integrated in the heater/air conditioning control unit can be used to regulate the air flow over the blower motor (M2).

Air recirculation mode (with code (I01) Air conditioning Plus)

By actuating the air recirculation switch (N23s3) on the heater/AC operating unit, the air recirculation flap actuator motor is actuated, which closes the air recirculation flap. As a result, supply of outside air is prevented; the air only circulates in the vehicle interior and unpleasant odors and harmful gases are kept out. The visual feedback of air recirculation mode takes place via the light-emitting diode integrated in the air recirculation switch.

Heater circuit function - GF83.20-P-2003MCU

MODEL 451.3 /4

Scheme 78

Function

The coolant pump pumps cold coolant through the engine. There, the coolant absorbs the engine heat and then flows over the thermostat to the coolant pump (small coolant circuit).

If the engine has reached its operating temperature, the thermostat opens the large coolant circuit. This subdivides immediately after the thermostat into the cooling circuit and the heating circuit.

In the heating circuit, the coolant flows to the heater heat exchanger via the heating circuit coolant feed pipe. The air flowing through the heater heat exchanger is warmed up in the process and routed into the vehicle interior.

Next, the coolant flows from the heater heat exchanger to the expansion reservoir and from there to the cooler or back to the coolant pump via the coolant return line.

In the cooling circuit, the coolant flows from the thermostat via the coolant feed pipe for the cooling circuit to the cooler and from there onward to the coolant pump via the coolant return line.

Automatic heater (HEAT) function - GF83.25-P-0001MCU

MODEL 451.3 /4 except CODE (I01) Air conditioning Plus

Description

The automatic heater has a mechanically adjustable heating and ventilation system. By means of the automatic heater, the vehicle interior can be heated or ventilated. It is only possible to cool down the vehicle interior to the temperature of the ambient air.

The following functions were realized

1. Heating circuit
2. Ventilation
3. Control

Heating circuit

The coolant is heated up by the engine. After this, the heated-up coolant is routed through the heater heat exchanger, where the heat is given off to the air flowing through the heater heat exchanger. The coolant returns back to the coolant pump via the heater return.

Ventilation

The ventilation system ventilates the interior of the vehicle. The air is drawn in by the blower motor (M2) and passes through the various air ducts to the air distribution flaps which distribute it in the vehicle interior.

Control

A specified temperature is preset on the temperature preselection slider switch. This setting is transmitted to the blend air flap in the heater housing via a cable. Depending on the position of the temperature preselection slider switch, the blend air flap distributes the air flow between the heater heat exchanger and the air outlet nozzles in the vehicle interior.

Automatic heater control function - GF83.25-P-2001MCU

MODEL 451.3 /4 except CODE (I01) Air conditioning Plus

Function

The automatic heater is regulated mechanically for the most part. The heater/AC operating unit (N23) is the central operating unit for regulating the heater. The air distribution rotary switch makes it possible to adjust which air outlet nozzles the air is to be routed through into the vehicle interior. The intensity of air heating is adjusted via the temperature preselection slider switch.

The heater heat exchanger located in the air flow of the blower delivers the heat of the coolant to the air blowing by. The strength of the air flow is set on the blower switch (S98/1) on the heater/ AC operating unit. The SAM control unit (N10/10) reads in the blower switch and then energizes the blower motor (M2).

Automatic air conditioning (AAC), function - GF83.40-P-0001MCU

MODEL 451.3 /4 with CODE (I01) Air conditioning Plus

The automatic air conditioning has an electronically controlled cooling and heating system. It controls the temperature of the vehicle interior.

Even at low outside temperatures, the air is first cooled down by the evaporator and dehumidified, it is then routed through the heat exchanger where it is heated up to the desired interior temperature.

The following functions are implemented

1. Ventilation
2. Heating circuit
3. Refrigerant circuit
4. Safety shutoff

Ventilation

The ventilation system ventilates the interior of the vehicle. The air is drawn in by the blower motor (M2) and passes through the various air ducts to the air distribution flaps, which distribute it in the vehicle interior.

Heating circuit

The coolant is heated up by the engine. The heated coolant is subsequently guided through the heat exchanger, where the heat is emitted into the air in the interior. The coolant returns back to the coolant pump via the coolant return line.

Refrigerant circuit

The refrigerant compressor (A9) driven by the engine compresses the refrigerant vapor which is cooled down in the condenser. The refrigerant liquefies during cooling. The refrigerant flows into the evaporator via the expansion valve and is heated there indirectly by the warm air blowing by on the outside of the evaporator. The refrigerant compressor aspirates the refrigerant which has turned gaseous on account of the heat absorption and then compresses it yet again.

Safety shutoff

To prevent damages to the refrigerant compressor, the following automatically shutoffs are integrated

1. Hot gas shutoff (through integrated sensor in refrigerant compressor)
2. High-pressure shutoff in the system (through refrigerant pressure sensor (B12))
3. Low-pressure shutoff in the event of missing refrigerant (through refrigerant pressure sensor)
4. Overtemperature deactivation (coolant temperature above 115°C)
5. Undertemperature shutoff (if temperature on evaporator is below 3°C) At outside temperatures below 3°C, the refrigerant compressor cannot be activated.

MODEL 451.3 /4 with CODE (I01) Air conditioning Plus

Scheme 79

Function

The refrigerant compressor driven by the engine aspirates the gaseous refrigerant from the evaporator, compresses it, and pushes it into the high-pressure circuit to the condenser as a hot gas.

The refrigerant gives off the compression heat through the surface of the condenser and liquefies in the process.

When it flows through the desiccant cartridge integrated in the condenser, the refrigerant is dehydrated and cleaned of chemical and mechanical impurities.

The expansion valve sprays the liquid refrigerant into the refrigerant line leading to the evaporator. In the process, the refrigerant pressure drops, whereby the aggregate state of the refrigerant starts to change from liquid to gaseous.

The refrigerant flows through the evaporator. While doing so, thermal energy is supplied to the refrigerant through the air blowing by the outside of the evaporator, which is needed by the refrigerant in order to be able to evaporate completely. At the same time, the air blowing by is cooled down, dried, and routed into the vehicle interior.

The condensation water developing while the air is cooling down is routed to the outside.

The refrigerant compressor aspirates the refrigerant which has turned gaseous on account of the heat absorption and then compresses it yet again.

Regulation of Automatic air conditioning, function - GF83.40-P-2004MCU

MODEL 451.3 /4 with CODE (I01) Air conditioning Plus

Scheme 80

Function

The automatic air conditioning is regulated via the heater/AC operating unit, which is networked with the vehicle electronics via CAN.
