What is the Proper Pressure for Car Air Conditioning?

[DiZoey]

Car air conditioning pressure should be between 1.3 to 1.7 MPa for the high-pressure side and 0.15 to 0.25 MPa for the low-pressure side. The usage method of car air conditioning is: 1. Turn on the AC switch; 2. Adjust the air outlet selection knob—direct the air upwards when cooling and downwards when heating; 3. Adjust the fan speed switch; 4. Adjust the air recirculation/conversion knob; 5. Adjust the temperature control knob. The functions of car air conditioning are: 1. Achieve cooling effect through the continuous cycle of refrigerant transformation; 2. Draw in fresh air from outside for ventilation and air exchange, preventing window fogging; 3. Utilize engine coolant, waste heat, or heat generated by a burner as a heating source, warming the air via a heater and distributing it into the cabin with a blower to raise the temperature for heating; 4. Remove dust, odors, smoke, and toxic gases from the cabin air, keeping it fresh, and humidify the cabin air to increase relative humidity.
