This requires knowing type of refrigerant and temperatures the system is running at.
The test or work book will have all this info so you can work it out.
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side
it is the low pressure side
Because it's the only way to recover it. You recover from the high pressure side, and charge it on the low pressure side.
You cool it and run it through a metering devise.
The difference in pressure between the high side and the low side of a refrigeration or air conditioning system is known as the pressure differential. This differential is critical for the proper functioning of the system, as it indicates the efficiency of the refrigerant cycle. Typically, the high side pressure is significantly greater than the low side pressure, which is necessary for the refrigerant to absorb heat from the environment and release it effectively. The exact values can vary based on system design, refrigerant used, and operating conditions.
The condenser does not have a low pressure side, because the condenser is not on the low pressure side of the system - it is on the high pressure side, and refrigerant going into the system is at high pressure throughout the whole of the condenser. The high pressure side of an AC system begins at the compressor outlet and ends at the metering device inlet (refrigerant leaves the compressor outlet and goes directly into the condenser inlet). The low pressure side runs from the metering device outlet to the compressor inlet.
Freon is typically added to the low-pressure side of an air conditioning system. This is because the low-pressure side is where the refrigerant is in a gaseous state, allowing it to absorb heat effectively. Adding refrigerant to the high-pressure side can lead to overcharging and potential damage to the system. Always consult the manufacturer's guidelines for specific instructions on your system.
That would depend on the type of refrigerant that is being used.
The pressure on the low pressure side of a refrigeration system is determined by the refrigerant's temperature and the system's design. As the refrigerant absorbs heat in the evaporator, it vaporizes and its pressure decreases. The size of the evaporator, the amount of refrigerant flowing through it, and the efficiency of the system also affect the pressure on the low side.
The high pressure (discharge) side starts at the compressor outlet and ends at the metering device inlet. This side will have the smaller refrigerant lines. The low pressure (vacuum) side begins at the metering device outlet and ends at the compressor inlet. This side will have the larger refrigerant lines.
The most basic thing is that is circulates refrigerant through the system. It also separates the low pressure side from the high pressure side of the system.
