302Section 3 A/C controlling systemI. Introduction and CompositionIn order to ensure the effective opeation of the A/C system in any operating condition, some advanced
electric control devices are used to protect the A/C system in adverse engine operating condition.
The electrical control part consists of: A/C switch, relay, evaporator temperature sensor, water temperature
sensor, pressure switch, ECU...etc.
A/C system circuit diagram is shown in Figure 6.II. controlling system feature(1) The condenser fan's power is 90W;
(2) The performance of the condenser fan is controlled by ECU, pressure switch;
(3) Cut off the electrical power of the A/C compressor clutch when the water temperature reaches 109°C;
(4) Connect blower switch 9 to rotate the blower motor 6 to ensure A/C normal operation. Connect A/C
switch 10 to output A/C request signal to ECU.
(5) After ECU receives the request signal and the one from the evaporator temperature sensor 17, if the
engine is at idle, ECU first increases the engine speed to 950 ± 50r/min, lest the A/C operation enhance
the load and lower the engine speed or result in engine off. And then the ECU can respond. If the engine
is in accelerating condition, ECU does not respond immediately either, and respond 5 seconds later after
the end of the accelerating condition. ECU send out a A/C control signal from pin 22 to relay 7, command
the relay to suction in. With the low pressure switch 11 closed, the compressor 12 starts to work when the
magnetic clutch suction on. The condenser relay holds in and condenser blower 13 rotates. When high
pressure switch 15 is closed, have the relay 7 hold in and the water tank fan 14 rotates. When the water
temperature sensor 16's temperature is higher than 109°C, ECU shut off the output signal of the pin 22
and A/C stops operation.
(6) When the Refrigeration system pressure is over 1.7MPa, radiator fan will rotato. Disconnect A/C
compressor Refrigeration system power supply when the pressure is over 2.6MPa or less than 0.25MPa;

303Figure 6 A/C System Electrical Appliance DiagramIII. Protecting Device1. Low temperature protection
Evaporator temperature sensor, when the sensed temperature is lower than 3°C, the compressor clutch
is de-energized and stops operation.
2. High temperature protection
Water temperature sensor, when the sensed water temperature reaches 109°C, the compressor clutch is
de-energized and stops operation.
3. Low pressure protection
When pressure sensed by the pressure switch is lower than 0.25MPa, the compressor clutch is de-
energized and stops operation.
4. Voltage protection
When the pressure sensed by the pressure switch reaches 1.7MPa, radiator fan rotates.
5. High pressure protection
When the pressure sensed by the pressure switch reaches 2.6MPa, the compressor clutch is de-energized
and stops operation.
6. Normal pressure
When system pressure reaches 0.25MPa~2.4MPa, control the A/C idle speed. Color of wire:R-Red Bl-Blue Y-Yellow Lg-Light green Br-Brown B-Black P-Pink G-Green W-White Gr-Gray

3063. Check for leakage if the reading changes and vacuumize it again.
4. Refill the new HFC-134a refrigerant if the reading doesn’t change.
Fill the new HFC-134a refrigerant
1. Connect the intermediate pipe to the refrigerant steel jar.
2. Open the refrigerant steel jar valve.
3. Weigh the refrigerant steel jar to charge the right refrigerant volume (refrigerant refill 630g¡À20g).Warning:•Check for air leakage or any other leakage when refilling large amount of refrigerant into the
Refrigeration system. The operator is recommended to fill small amount of refrigerant first to
prevent the refrigerant from leakage, which will result in ozonosphere damage.•It is very dangerous to open the engine high pressure side valve if filling the refrigerant with
the service tank. The pressure in the service tank will rise during the operation, which will
result in the service tank explosion. The exploded mental fragment and the splashed refrigerant
will hurt the operator badly. Therefore, do close the high pressure side valve when the engine
is working.4. Open the manifold gauge low pressure side valve.
5. Close the manifold gauge low pressure side valve when the manifold gauge low pressure side reading is
increased to 0.098Mpa{1.0kgf/cm2}.
6. Check cooling pipeline/hose for leakage with leak detector.
•Proceed to step 8 if there is no leakage.
•Tighten the union joint if there is leakage at the loosened union joint and go to next step.
7. Re-check the leaked points.
•Go to next step if there is no leakage after tightening the union joint.
•If there is still leakage at the same union joint, drain refrigerant and repair the union joint. Repeat
the filling procedure and vacuum it.
8. Open the valve at the low pressure side of the manifold gauge. Fill the refrigerant until the refrigerant
tank weight from the one mentioned in Step 3 drop to 250g.
9. Close the valve at the low pressure side of the manifold gauge.
10. Start the engine and switch on A/C.
11. Open the valve at the low pressure side of the manifold gauge. Fill the refrigerant until the refrigerant
tank weight from the one mentioned in Step 3 to specified value.
12. Close the valve at the low pressure side of the manifold gauge and the valve of the refrigerant steel jar.
13. Stop the engine and A/C compressor.

307Check For Leakage:
1. Using leak detector, check refrigerant steel jar for leakage.
•Go to Step 3 if there is no leakage.
•Tighten the union joint if there is leakage at the loosened union joint and go to next step.
2. Re-check the leaked points.
•Go to next step if there is no leakage after tightening the union joint.
•If there is still leakage at the same union joint, drain refrigerant and vacuum the union joint.
3. Disconnect the high and low pressure pipe at the refill valve.
4. Install the filling valve cap.
Check Refrigerant Pressure:
1. Install the manifold gauge.
2. Warm up the engine and run it with constant 1800rpm.
3. Set the rpm of the cooling fan to the HIGHEST.
4. Turn on the A/C switch.
5. Set to internal circulation mode.
6. Set the temperature control mode to the COLDEST.
7. Set to be ventilation mode.
8. Close all door and windows.
9. Measure the environment temperature and the reading of the high pressure side and low pressure side
from the manifold gauge.
•Shoot the Refrigeration system trouble as required if it is not as specified in the technical specification.
The Performance Inspection of the Refrigeration System:
1. Check refrigerant pressure.
•Go to next step if the pressure value is correct.
•Shoot the Refrigeration system trouble promptly if the pressure value is not as specified in the
technical specification.
2. Insert a thermometer into the middle vent port at the driver's side.
3. Warm up the engine and run it at the constant 1800rpm.
4. Set the rpm of the cooling fan to the HIGHEST.
5. Switch on A/C.
6. Set to internal circulation mode.
7. Set the temperature control mode to the COLDEST.
8. Set to Ventilation Mode.
9. Close all doors and windows.
10. Wait until A/C output temperature is constant. (When the environment temperature is 38°C, the temperature
at the middle ventilation port at the drivers side is 10°C~16°C. )
