What are the four main components of a refrigeration system?

The four main components of a refrigeration system are accurately identified in the choice that lists the compressor, condenser, metering device, and evaporator.

The compressor is crucial as it compresses the refrigerant and raises its pressure, facilitating the movement of the refrigerant through the system. Following this, the condenser plays a vital role by allowing the refrigerant to release heat to its surroundings, thereby converting the refrigerant from a gas to a liquid state.

The metering device, such as a thermal expansion valve, serves to regulate the flow of refrigerant into the evaporator and ensures that the refrigerant enters in the correct amount and at the necessary pressure. By controlling the refrigerant's flow, it optimizes the cooling process.

Finally, the evaporator absorbs heat from the environment, causing the refrigerant inside it to evaporate and thus cools the surrounding area. This cycle of compressing, condensing, metering, and evaporating is what allows a refrigeration system to efficiently remove heat and maintain desired temperatures.

The other options include valid components of refrigeration systems but do not represent the complete set essential for a basic refrigeration cycle. For example, some include elements like a liquid receiver or an accumulator, which are used in specific types of
