1. The Harm Of Not Cleaning The Air Conditioning System In Time
Air conditioning filters such as not by the provisions of the cleaning, a large amount of dust and oil once into the evaporator core, will seriously affect the heat transfer efficiency of the evaporator, refrigeration effect is significantly reduced, the power consumption straight up. Seriously causes filter clogging, air conditioning wind small, evaporator liquid refrigerant evaporation incomplete into the compressor compressor “liquid shock” failure.
After air conditioning after some time, there will be a lot of flocculent adherents on the dust filter. These attachments by the human body shed dander, cleaning, changing clothes, and smoking, etc. produced by the suspended matter gathered, these attachments become a breeding ground for bacteria. According to professional doctors, if you do not pay attention to air-conditioning cleaning, these substances will be sent into the cabin with the cold air, which will not only lead to dizziness, drowsiness, sneezing, and other uncomfortable symptoms but also may cause allergic skin diseases or trigger asthma.
Note: For dusty areas, the return air filter and core dust net and cleaning time can be shortened by yourself according to the actual situation.
2. Cleaning Method
(1) Return Air Filter Cleaning
First of all, use compressed air to clean the flocculent adherents on the surface of the return air grille, and spray the sterilization agent. Then use water to clean the dust attached to the filter (where possible, high-pressure water gun, high-pressure water gun nozzle as far as possible into a decentralized, to prevent the local grid washed out). Until the water is flushed out clean, wash the clean filter screen into the ventilation or sunlight to dry until no water drips down.
(2) Cleaning Of Core Body Dust Screen
Core body dust mesh in the melt cleaner soaked in water then scrubbed, and put into the water (conditions where available high-pressure water gun, high-pressure water gun nozzle as far as possible into a decentralized, to prevent the local grid washed out). Until the wash or flush out the water is clean, and will wash the clean screen into the ventilation or sunlight to dry until no water drips down.
(3) Evaporator Core Cleaning
Remove the dust net on both sides of the air conditioner evaporator. Then use compressed air to clean the dust on the fins of the evaporator core. Subsequently, flush the evaporator core with a water gun (if necessary, you can use laundry detergent to clean with the help of a brush). Finally, use compressed air to dredge the evaporator drain, blow clean air conditioning evaporator core, and PTC temperature control connectors on the water.
(4) Condenser Core Cleaning
The condenser core body on both sides of the debris was cleaned up. Then use compressed air to clean the condenser core fins on the dust. Then rinse the condenser core with a water gun (if necessary, use washing powder and clean it with the help of a brush). Finally, check the condenser drain hole for debris or dust accumulation, and deal with cleaning to ensure smooth drainage.
3. Fault View
In air-conditioned electric buses, the control panel on the A/C switch has a fault display function. The driver finds the fault alarm (﹤ ﹥ and refrigeration light flashing) in the process of using it. After pressing the browse button to see what the fault code is, the power should be turned off immediately and reported for repair, which will be handled by professional maintenance personnel.
Of course, the air conditioning system of new energy bus vehicles, like other parts, needs not only standardized use but also careful maintenance. So that it can play out the maximum performance for the public passengers to bring a cool and healthy environment inside the vehicle.
