AIR CONDITIONINGAir conditioning: Precautions for repair

AIR CONDITIONING or CLIMATE CONTROL

62AI - SAFETY

Refrigerant is heavier than air. As a result there is a riskof asphyxia for those working close to the ground andless than 5 m away from the working area (pit, well, airvents, etc.).

Switch on gas extraction systems.

At temperatures above 100˚C, the refrigerant will de-compose and produce a highly irritant gas.

II - GENERAL RECOMMENDATIONS

It is possible to place components in the drying ovenafter painting or to carry out work near the system if thetemperature does not exceed 80˚C.

It is essential to follow the routing of the connecting pi-pes.

Ensure that the refrigerant connecting pipes are cor-rectly fitted so that they will not come into contact withmetal parts in the engine compartment.

IMPORTANT

The following must be worn when handling refrige-rant:

- gloves,

- protective goggles (with side shields if possible).

In the event of refrigerant fluid coming into contactwith the eyes, rinse well with clean water conti-nuously for 15 minutes. If possible, have an eyerinse unit available.

If refrigerant comes into contact with your eyes,consult a doctor immediately. Inform the doctor thatthe burns were caused by R134A refrigerant.

In the event of contact with other unprotected partsof the body (event though the safety advice hasbeen observed), rinse well with clean water conti-nuously for 15 minutes.

IMPORTANT

Work requiring the use of refrigerant must be car-ried out in a well-ventilated area.

The refrigerant must not be stored in a shaft, a pit,a hermetically sealed room, etc.

Refrigerants are colourless and odourless fluids.

IMPORTANT

It is forbidden to smoke close to an open refrigerantcircuit.

IMPORTANT

To prevent refrigerant from leaking, never repair afaulty air conditioning circuit component.

Replace all faulty components.

WARNING

In order to avoid any refrigerant leaks, do notdamage (deform, twist, etc.) the pipe.

WARNING

To avoid damaging the surface of the air conditio-ning pipes when removing the seals, do not use atool with a metallic end piece.

WARNING

To prevent moisture from entering the system,place plugs on the cold loop components which areopen to the air.

WARNING

To prevent any leaks, check that the seal and sur-face of the pipe are in good condition. The seal andthe surface must be clean and free from scratches.

WARNING

Lubricants are not mutually compatible: alwaysobserve the type and quantity of oil recommendedfor each compressor even when topping up as thiscould damage the cold loop components.

Always close the oil cans again after use to keepmoisture out and never use oil contained in a canthat has been open for a long time (viscous appea-rance).

I - PREPARATION OPERATION FOR THE MEASUREMENT DEVICE

a Check that the measurement device functions pro-perly (see the device's instruction manual).

a Set units to ˚C.

a Set the device's sensitivity to 0.1˚C.

a Set the reading mode to (∆T) = (T1 - T2)

a Check the two sensors T1 and T2 in order to calcu-late the correction (∆) to be applied to the measure-ment (T1 - T2). the two sensors must indicate the same measurement under the same conditions. Check the sensors by:

- bringing the ends of the 2 sensors together untilthey touch,

- placing the sensors in the air flow of an air vent,

- setting the passenger compartment fan assemblyto top speed.

- waiting for the value to become stable.

- recording the correction value (∆).

Equipment required

Dual-sensor temperature measuring device

Note:

When performing RENAULT maintenance, checkthe air conditioning system at the end of the vehi-cle's maintenance program so that the engine willbe cold.

119360

119358

Note:

It is not necessary to start the vehicle. Thedevice display is in mode (∆T) = (T1 - T2).

WARNING

Note the difference and sign as soon as the tem-perature becomes stable.

Calculate the correction (∆) = - (T1 - T2) to beapplied to the measurement (∆T).

Examples:

If (T1 - T2) = - 0.3˚C, correct the measurement(∆T) by (∆) = + 0.3˚C

If (T1 - T2) = + 0.3˚C, correct the measurement(∆T) by (∆) = - 0.3˚C

62A-5



62AII - VEHICLE PREPARATION OPERATION

a Put the vehicle in the shade, where the temperatureis greater than or equal to 15˚C minimum.

a Close the bonnet.

a Open the front windows.

a Start the engine and let it idle.

a Set the air conditioning controls with:

- recirculation mode in the external position,

- the ventilation distribution in "face" mode,

- the temperature control to coldest temperature set-ting in front (and at the back, if it exists),

- the speed of the passenger compartment fan as-sembly set to maximum (switch off the rear controlif it exists),

- the front side and centre air vents open with the va-nes in a neutral position,

- the air conditioning system must be turned on (indi-cator light illuminated).

a Wait 5 minutes with the engine idling before ta-king any measurements.

III - MEASUREMENTS

a Record the air temperature at the scuttle panel grille (T3).

- open the bonnet, depending on the vehicle, to ac-cess the scuttle panel grille.

- place the sensor where air is drawn through thescuttle panel grille.

- wait for the value to become stable.

- record the T3 temperature value.

- close the bonnet if it was opened.

a Record the air temperature at the left air vent (T1), and at the right air vent (T2).

- fit sensor T1 in the left air vent (1) .

- fit sensor T2 in the right air vent (2) .

a Record the differences in temperature once the (∆T) value has stabilised:

- between T3 and the higher of values T1 or T2, (T3- highest value).

- record this difference in temperature.

- between T1 and T2 (read the (∆T) value (T1-T2)display mode).

- record the difference in temperature (∆T) accor-ding to the correction (∆) to be applied to themeasurement.

a If the (∆T)=(T1-T2) measurement is unstable, followthe procedure below:

119359

119357

Note:

Depending on the vehicle's air conditioning sys-tem programming, this check method may not beapplicable because the engine cooling fanassembly has been activated. Its operation ren-ders the (∆Τ) value between T1 and T2 unstable.To eliminate this error, the fan assembly must beactivated for the entire period over which tempe-rature T1 and T2 measurements are recorded.

62A-6



62Aa Activate the engine cooling fan assembly operation

by modifying the engine speed.

- stabilise the engine speed at 2000 rpm while T1and T2 temperature measurements are being re-corded.

- check that the engine cooling fan assembly opera-ting.

- record the temperatures by following the instruc-tions given in the paragraph MEASUREMENTS.

IV - FAULT FINDING PROCEDURE

a The following two following conditions must be met:

- the difference between T3 and the higher of the twovalues T1 or T2, must be greater than or equal to5˚C,

- the difference between T1 and T2 must be lessthan or equal to 2˚C.

Note:

If one of these two conditions is not met, then theair conditioning system is not working properly.Should this be the case, refer to the fault findingprocedure for the air conditioning system for thevehicle concerned.

- the engine is running but the air conditioning is notin operation (B),

- the engine is not running nor is the air conditioningin operation (C).

a Scenario A:

- Operate the air conditioning until the cooling fanassembly is triggered twice,

- Switch off the engine,

- drain for the first time (note down the original va-lue),

- wait 15 minutes,

- check that the relative pressure is no more than 0bar,

- repeat the cycles until the relative pressure is equalto or less than 0 bar,

- add together the values of the various drainingoperations; the fill is confirmed as being correct ifthe volume of refrigerant fluid is the specified fill+35g or -100g.

Scenario B:

- run the engine until the cooling fan is triggered twi-ce,


- drain for the first time (note down the value),

- wait 15 minutes,

- run the engine until the cooling fan is triggered twi-ce,


- drain for the second time (note down the value),



Scenario C:

- drain for the first time (note down the value),

- wait 2 hours,



II - CREATING A VACUUM

a It is essential to carry out vacuum extraction correct-ly before loading, otherwise the air conditioning willnot work properly.

There are two scenarios to consider:

- vacuum created immediately after discharge (sce-nario A),

- vacuum created after an interval of several hoursor days (scenario B).

Scenario A:

- creation of a vacuum takes 20 minutes.

Scenario B:

- creation of a vacuum takes 45 minutes to elimina-te any trace of moisture.

a Test the seal once the vacuum has been created(some stations do this automatically).

III - FILLING

a Fill up the refrigerant circuit using the refrigerantcharging station.

Note:

- If the air conditioning circuit is fitted with a sin-gle filler valve, some filling equipment onlyrequires the use of the high pressure pipe (referto the filling station instructions).

- Depending on the situation, run the system fora few minutes before recovering the coolant toimprove drainage.

Note:

It is essential to follow these procedures to pre-vent:

- gas escaping when the circuit is opened,

- pollution of the environment through the releaseof gas into the atmosphere when the circuit isopened or when a vacuum is created.

62Aa Top up the oil with the recommended type and volu-

me of oil and refrigerant, depending on the work car-ried out (see 6 2 A, Air conditioning, Airconditioning: Parts and consumables for the re-pair work, page 62A-2) .

a Check there are no leaks using the electronic de-tector (see 62A, Air conditioning, Coolant circuitcheck, page 62A-7) .

a Check that the air conditioning system is operatingcorrectly (see 62A, Air conditioning, Air conditio-ning: Check, page 62A-4) .

WARNINGAfter injecting dye into the refrigerant, be sure toindicate this on a label (supplied with the dyecapsule), and the date of the operation.

Position the label so it is visible near to the coldloop filler valve.
