III. Installation Location and Core Functions
1. Installation Location: Behind the dashboard in the cab, inside the air conditioning evaporator housing, integrated assembly of dual impellers + DC motor + speed-regulating resistor module.

2. Core Functions:
* Cooling Air Supply: The motor drives the dual impellers, and airflow passes through the evaporator core to carry away the cold air, delivering cool air to the cab;
* Heating Air Circulation: In winter, airflow passes through the heater core, delivering warm air;
* Airflow Level Adjustment: Equipped with an integrated speed-regulating resistor, supporting multi-level airflow control, matching the cab air conditioning control panel;
* Vehicle Electrical Matching: 24V DC power supply, working in conjunction with a 24V on-board generator and battery.
