The low pressure side.
Liquid
Liquid
The charging liquid is typically added to the low-pressure side of a compressor. This allows the liquid to enter the compressor, where it is compressed and then discharged as a high-pressure gas.
High side, If you charge liquid on the low side it can cause the valves of the compressor to break.
yes
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does that make sense?
The side of the compressor that is normally charged is the low-pressure side. This is where the refrigerant enters the compressor after absorbing heat from the environment. Charging typically involves adding refrigerant to the system through the low-pressure service port, allowing the compressor to efficiently circulate the refrigerant throughout the system. Proper charging ensures optimal performance and efficiency of the HVAC system.
The Low side line attaches to the compressor on the driver side of compressor. The charging port faced forward. The high pressure port faces up.
You should just let the system take the refrigerant out of the can by itself. It is not good to force liquid r134a into the low pressure side of the ac. The suction of the compressor will draw the r134 out by itself and stabilize the system as it goes, it may just take longer than you want.
The high-side service valve is closed during charging to prevent the flow of refrigerant to the low-pressure side of the refrigeration system. This valve is typically located on the discharge line of the compressor and is used to isolate the high-pressure side of the system during service or maintenance.
You can find the air conditioning low pressure charging port on top of the air conditioning compressor. The low pressure port will be on the right hand side of the air conditioning compressor.
there is a high side charging port up top and a low side underneath the car on the compressor.
