Which side do you add refrigerant?

Which side do you add refrigerant?

The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.

Is the suction side the low side?

The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.

What is the high side of an AC system?

The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position. It will not be wrapped in insulation and will be warm to the touch. This is where freon exits the compressor as a liquid.

Where do you charge liquid refrigerant?

With the system running, proceed to charge the refrigeration unit – by opening the refrigerant supply valve to meter refrigerant out of the measured charge device, passing refrigerant through the vaporizing attachment and into the low-side of the air conditioner, heat pump, refrigerator or other appliance being charged …

What is charging of refrigerant?

The refrigerant charging in Refrigeration system or AC system is done because refrigeration effect in it cause decrease in refrigerant due to leakage of gas. The leak must be detected and rectified in the refrigeration system before the refrigerant is charged.

Where is the high side charger port on a car AC?

Do you charge AC on high or low side?

You’ll recharge your AC through the low-pressure port. You should consult your owner’s manual to be sure, but your vehicle will have a cap over the pressure ports.

Which is the correct way to charge a refrigerant compressor?

Always charge the vapor refrigerant from the point where the system pressure is lower than the pressure in the charging cylinder. If we try to charge from the discharge side of the compressor, then instead of refrigerant going from the charging cylinder to the system, it may start reversing, filling the charging cylinder itself.
