A low side refrigeration system primarily consists of several key components: the evaporator, where the refrigerant absorbs heat from the environment and evaporates; the compressor, which circulates the refrigerant and increases its pressure; and the condenser, where the refrigerant releases heat and condenses back into a liquid. Additional components may include an expansion device to control refrigerant flow and pressure, and various sensors and controls to regulate the system's operation. Together, these parts work to maintain desired temperatures in refrigeration applications.
Low side.
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.
Refrigerant should be added through the low side of the system. This is typically done while the system is running, as adding refrigerant through the high side can be dangerous due to high pressures. It is important to follow manufacturer guidelines and use proper equipment when charging a refrigeration system.
king valve
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.

The compressor changes the low pressure gas into a high pressure gas which then has the heat of compression removed in the condensor to turn it into a high pressure liquid.

There are two parts which do. The first is the compressor - the high side starts at the compressor outlet. The other is the metering device (either a Thermal Expansion Valve or a Fixed Orifice Tube). The high pressure high ends at the metering device inlet. The low pressure side starts at the metering device outlet and ends at the compressor inlet.
The condenser is a coil in a refrigeration system. It is on the low pressure side and is exposed to ambient air temp. The refrigerant goes through that and is cooled off and is then sent to the compressor.
