What is the approximate pressure for recharging refrigerant in a car's air conditioning system?

[DelilahLynn]

The pressure for recharging refrigerant in a car's air conditioning system is: 1. The low pressure is 2.0 to 2.6 bar; 2. The high pressure is 15 bar. Maintenance methods for air conditioning use are: 1. Do not set the temperature too low; 2. Control the direction of the air outlet; 3. Avoid prolonged use; 4. Occasionally use high fan speed; 5. Turn off the air conditioning when driving at low speeds. The functions of the air conditioning system include: 1. Achieving a cooling effect through the continuous phase change cycle of the refrigerant; 2. Removing dust, odors, smoke, and toxic gases from the car's interior air to freshen it, and humidifying the interior air to increase its relative humidity; 3. Using engine coolant, waste heat, or heat generated by a burner as a heat source to warm the air, which is then blown into the car by a blower to raise the temperature at the air outlets for heating purposes.
