At the discharge line of a compressor, the refrigerant is typically in a high-pressure, gaseous state. It has been compressed, increasing its temperature and pressure, and is ready to be directed to the condenser. The refrigerant's high energy content at this stage facilitates the heat transfer process as it moves through the refrigeration cycle.
A higher-than-normal temperature on the discharge gas line of a reciprocating compressor could indicate issues such as low refrigerant charge, restricted flow in the system, or a failing discharge valve. It is important to address these issues promptly to prevent damage to the compressor and ensure efficient operation of the system.
A refrigerant compressor will be hot when running whether or not the charge is too high or too low. If the charge is too low, the compressor will cycle on and off. If too high the compressor may not run at all.
Can't do it. The lubricant is mixed in with the refrigerant. Converted to air it would be running dry.
If a compressor has faulty valves, it can lead to increased head pressure due to the inability to properly compress and discharge refrigerant. This can cause inefficiencies in the system and potentially lead to overheating of the compressor. Regular maintenance and timely replacement of faulty components are recommended to prevent further damage.
If liquid refrigerant enters the compressor cylinder while it's running, it can damage the compressor. Liquid refrigerant is not compressible like gas, causing hydraulic lock and putting excessive strain on the compressor motor. This can lead to mechanical failure and decreased efficiency of the refrigeration system.
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.
If the compressor in a refrigerator stopped working, the heat transfer cycle would be disrupted because the compressor is responsible for circulating refrigerant and compressing it to remove heat from the interior of the refrigerator. Without the compressor, the refrigerant cannot absorb heat from the interior and release it to the surroundings, resulting in a lack of cooling inside the refrigerator.

When you are replacing a compressor. Chances are that the compressor's internal motor had a burnout when this happens the there is a chemical reaction that makes everything very acidic this in-turn contaminates the refrigerant as well. The old refrigerant would be reclaimed and sent to a a reclamation center where it would be incinerated under the guidelines by the Dept of EPA .
Legally you can't without the EPA's Secton 609 certifacation, because any refrigerant in the system must be removed by a licensed technician. And even if its empty of refrigerant, after you relace the compressor you must pull a vacuum on the system to remove air and moisture. I would recomend taking it to a garage. The guy above probably owns an AC garage. You need to have a certified mechanic "discharge" and "re-charge" the refrigerant. However, the act of replacing the AC compressor can be done by you (although this depends on "you"). My local shop charges $85 to remove the refrigerant and replace it again after I have changed out the compressor. Tomorrow I will take the old compressor off and put the new one in...from what I gather so far...this entails removing the plastic cover below the compressor, remove the belt, remove the compressor, replace the new one and use a wrench on the belt "auto-tensioner" to get the belt back on. Run the car and make sure it works properly...then take it back to the garage, get the refrigerant re-charged and you should be good to go!
Possibly the pressure cycling switch.
Refrigerant is typically charged into the low-pressure side of the compressor to ensure the system operates correctly and efficiently. Charging refrigerant into the high-pressure side can lead to issues such as system damage, inefficient operation, or inadequate cooling.
