III. Installation Location and Core Functions
1. Installation Point
Engine side bracket, driven by the engine pulley, connected in series with the air conditioning condenser and evaporator W48000377, forming a complete refrigeration cycle.
2. Core Functions
Refrigerant Compression Refrigeration: The rocker-piston structure compresses R134a refrigerant, increasing the pressure from low-pressure gaseous refrigerant to high-temperature, high-pressure gas. This gas dissipates heat through the condenser and absorbs heat through the evaporator, providing cool air to the cab.
Electromagnetic Clutch On/Off Control: A built-in 24V electromagnetic clutch engages when the air conditioning panel is energized, pulling the pulley and driving the pump. Turning off the air conditioning disengages the clutch, stopping the compressor.
Stable Cooling Under Heavy Loads: The 7H15 large-displacement design provides ample cooling capacity even at low idle speeds, suitable for long-term earthmoving and heavy-duty mining operations of loaders.
