What are the essential elements of a refrigeration system in order from the low side?

The essential elements of a refrigeration system, when arranged from the low side, start with the evaporator, followed by the compressor, then the condenser, and finally the metering device. This sequence accurately reflects the flow of refrigerant and the operational processes within the refrigeration cycle.

Starting with the evaporator, this component is crucial as it absorbs heat from the environment, causing the refrigerant inside to evaporate and cool the area being refrigerated. This is the low-pressure side of the system where the refrigerant is in its gaseous state after absorbing heat.

Next in the sequence is the compressor, which takes the low-pressure gas from the evaporator and compresses it into high-pressure gas, raising both its temperature and pressure. This compression is vital as it prepares the refrigerant for the next stage of the cycle.

Following the compressor is the condenser. Here, the high-pressure gas released from the compressor dissipates its heat to the surrounding environment and condenses back into a liquid. This step is essential for the refrigeration cycle, as it allows the refrigerant to return to a liquid state before moving to the metering device.

Finally, the metering device regulates the flow of refrigerant into the evaporator, helping to maintain the correct amount of refriger
