Description

The compressor is the power unit of the air conditioning system. It is located on the side of the cylinder block and is driven by the engine drive belt. The compressor converts low-pressure, low-temperature gaseous refrigerant into high-pressure, high-temperature gaseous refrigerant. Variable Swash Plate Compressor: The compressor has a swash plate that rotates to reciprocate the pistons and compress the refrigerant. The variable swash plate compressor adjusts the swash plate angle to change refrigerant displacement. This provides precise control of cooling capacity according to cabin and driving conditions. Internal control variable compressor: adjusts the swash plate angle using the MCV (mechanical control valve) in response to suction pressure fluctuations. External control variable compressor: adjusts the swash plate angle using the ECV (electronic control valve) in response to an electrical signal from the heater and A/C control unit. This provides stable temperature control and improves driving comfort. ECV Control Circuit
