5.2.1 At the preheating temperature rise stage, the vehicle is parked in the test site with all doors and windows closed; it is exposed to direct sunlight for 90 min under the conditions of 4.5.2.
5.2.2 Test participants enter the vehicle, start the engine, start the vehicle, record the initial readings at all measuring points and set the vehicle at maximum refrigeration. 5.2.3 The working conditions shall include starting, acceleration, gear shifting, braking, stopping, idling and so on; the vehicle is operated by reference to the cyclic working conditions for urban operation as specified in GB 18352.3-2005, with the test duration of 45 min; record data as required in 5.1.1.4.
5.3 Frosting test method for air-conditioning system
5.3.1 Test participants (at least 2) enter the vehicle; set the temperature switch to the maximum refrigeration mode position, the air circulation switch at the outer circulation position and the air volume switch at the maximum gear; after the vehicle runs for 30 min at the speed of 100 km/h (if the maximum speed of the vehicle cannot achieve 100 km/h, it is allowed to run at a speed 8 km/h ~ 10 km/h lower than its maximum speed), change the air volume switch to the minimum gear; run once again for 30 min; stop rapidly; check whether frost forms on evaporator and low pressure pipelines; carry out the test twice.
5.3.2 During the whole test process, observe from time to time whether the temperature at the air outlet rises; if it rises, stop the vehicle rapidly and check whether frost forms on evaporator and low pressure pipe lines.
5.4 Pressure test method for air-conditioning refrigeration system
5.4.1 Run the vehicle for preheating.
5.4.2 Park the vehicle at the test site; set the vehicle at maximum refrigeration; from the idle speed to the rated rotational speed of engine, carry out measurement at the interval of rotational speed 500 r/min at most (on at least 5 measuring points). After the rotational speed is stabilized for 10 min at each measuring point, acquire the data of suction-exhaust pressure of compressor as specified in B.2 of Annex B; and plot the curve of suction-exhaust pressure.
