Spring: at the beginning of air conditioning operation in spring, first check whether the oil quality of compressor is normal, clear and transparent without blackening and deterioration; whether the oil level is normal (3 /4-1 / 3); observe whether the pipeline to the interface is normal, whether there is oil leakage; whether the contact point of the connector is normal; observe whether the air output of the fan is consistent with the normal; check whether the belt is loose; check whether the evaporation and condensation core body heat dissipation is normal. Note: before using the air conditioner, slowly rotate the compressor clutch with hands or tools to facilitate the lubrication of compressor oil and avoid compressor damage caused by starting the air conditioner.
Summer: during the peak period of air conditioning use in summer, take the week as the standard, check whether the pipeline interface and compressor are normal, and whether the harness interface is loose and fastened; clean the dust screen and suction filter screen once a month, which will help improve the cooling effect of air conditioning
Autumn: the air conditioner will enter the off-season in autumn, mainly check the compressor to ensure that the oil quantity of the compressor is large, the oil quality of the compressor is clear, and there is no blackening and deterioration. Check whether the pipe joint screw is loose; check whether there is oil leakage, etc. Clean the dust screen and suction filter screen once a month to facilitate the use of air conditioning.
Winter: winter is the off-season of air conditioning. Do not take off the compressor belt when driving in winter; check the oil volume of the compressor regularly every month. The air conditioning system shall run at least once a month, each time for about 10-30 minutes, to ensure that all interfaces of the system pipeline are fully lubricated and effectively prevent refrigerant leakage in winter.
