Eco-friendly bus fleets aiming for energy efficiency and sustainability.

1. The refrigerant is R407C.

2. The air-conditioning unit is overall installed above the rear engine, and should be considered for installation to be shoveled in as a whole, and shoveled out for overhaul. The air duct of the transitional connection between the unit and the air duct in the car should be easily installed.

3. It must be ensured that the condensing fan air enters  and exhausts wind smoothly, and that the intake and exhaust air is effectively cut off without wind and short circuit. The wind speed of the vehicle side must be ≤5m/s.

4. The air duct of the transitional connection from the air conditioning unit to the air duct in the bus has a special shape, so the design should fully consider the operability of the installation and reduce the resistance of the air duct. The wind speed of the transition duct must be ≤12m/s.

5. The wind speed of the main air supply duct in the bus must be ≤8m/s.

6. It is best to set the air return grille separately according to the air volume ratio of the upper and lower floors. Or it can be set separately for the upper floor, and the lower floor returns air through the stairway.

6. Electrical control assemblies such as electric control boxes and inverters occupy a certain amount of space in the vehicle, and must be considered in a ventilated and waterproof position.

7. JLE-IIIB-T back-mounted (heat pump plus PTC) integrated battery thermal management function.

1. The overall frame structure, combined with the aluminum alloy shell, is large in size and light in weight.

2. Adaptive frequency conversion technology realizes synchronous variable speed conditions of compressors and fans, reducing operating energy consumption.

3. Custom development, modular design, light weight.

4. DC brushless fan, long life and light weight.

5.The heat pump design, compared with conventional transformation, can realize heat pump heating and reduce energy consumption.

6.CAN bus control, reserve interface and background for the subsequent popularization of bus networking technology.
