The pressure in a refrigeration system changes in the compressor, condenser, expansion valve, and evaporator. In the compressor, the pressure increases, while in the condenser, it remains high before decreasing in the expansion valve and evaporator.
There are four main parts of refrigerator. A compressor A condenser A Metering Device(capillary tube) An Evaporator
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 narrow tube used as a metering device in refrigeration and air conditioning systems is called a capillary tube. It helps to regulate the flow of refrigerant into the evaporator coil to control the cooling process.

The condenser is the component of a refrigeration system that changes high-pressure vapor into high-pressure liquid by transferring heat to the surrounding environment. This process involves the conversion of refrigerant from a gas to a liquid state by releasing heat to the outside air or water.
To condense refrigerants that are capable of achieving ultra low temperatures that would not be able to condense at room temperature. This is achieved by using a low temperature evaporator of one system as the condenser the other, condensing and subcooling the liquid before entering the metering device.
