As new energy buses gradually enter the public’s field of vision, new energy buses are deeply loved by passengers due to their low operating noise, comfortable riding experience, and high configuration. This article mainly describes the use and maintenance methods of pure electric bus air conditioners.
Safety precautions for use
1. If a fault alarm occurs during the operation of the air conditioner, the air conditioner power switch should be turned off immediately.
2. During the operation of the air conditioner, the system carries high voltage electricity. It is strictly forbidden to open the system cover and touch the system components.
3. All kinds of electrical equipment of electric air conditioners are strictly prohibited from working with water.
4. Non-professional maintenance personnel are strictly prohibited from disassembling and assembling various components without authorization to prevent accidents.
5. It is strictly forbidden to short-circuit the high and low voltage switches of the system during the operation of the air conditioner.
Requirements for the use environment
1. When the air conditioner is running, in order to achieve the ideal working effect, close the doors and windows inside the car and the circulation outside the car.
2. Air conditioner temperature requirements, it is recommended to set 24-26° in summer and 18-20° in winter. Appropriate temperature adjustment will reduce the operating time of the air conditioning system, increase mileage, and reduce energy consumption.
3. Precautions for using air conditioners
1. It is strictly forbidden to use the air conditioner when the air conditioner fails or is undervoltage.
2. It is strictly forbidden to close all the air outlets during the operation of the air conditioner.
3. It is not allowed to short-circuit the high and low pressure switches during the operation of the air conditioner.
Daily use and maintenance of air conditioners
1. Check the cleanliness of the return air filter and evaporator filter and clean the filter on time
▶ Generally, buses are required to be flushed once or twice a week and long-distance tourist buses are required to be flushed once a week. For areas with heavy dust, the cleaning time can be shortened according to actual conditions.
▶ In the season when the air conditioner is not used, the filter should be cleaned at least once a month.
2. Check the refrigerant quantity and dryer condition:
3. Check the cleanliness of the evaporator and condenser core fins and clean them once a year.
4. Frequently check whether the exposed wiring harness, wiring harness connectors, and wiring terminals have interference, wear and looseness.
