64529332199 Electric Vehicle Air Refrigeration Pump Ac Air Conditioning ,Compatible For Bmw The air conditioning pump is responsible for compressing the low-pressure refrigerant and driving the entire cooling cycle, making it the core component of air conditioning. The cold air pump helps the system complete heat exchange by pressurizing and heating the refrigerant, achieving cooling inside the car. The refrigeration compressor assembly changes the refrigerant’s pressure and temperature through mechanical work, ensuring the air conditioner can cool steadily. The vehicle refrigeration pump continuously delivers high-pressure refrigerant, working with other components to complete the whole heat absorption and release process., Manufacturer: CKBVJQZLXMH
