Which component is NOT included on the low-pressure side of a compression refrigeration system?

In a compression refrigeration system, the low-pressure side encompasses elements that handle the refrigerant in its gaseous state after it has absorbed heat from the environment. This includes the suction side of the compressor, the evaporator, and all the associated tubing and piping that transport the refrigerant between these components.

The condenser, on the other hand, is part of the high-pressure side of the system. It takes the high-pressure refrigerant vapor from the compressor and cools it down, allowing it to condense into a liquid by releasing heat. Since it operates under high pressure and involves the transition from a gas to a liquid state due to heat rejection, the condenser does not belong to the low-pressure side.

Understanding the roles of these components helps clarify their operational distinctions in the refrigeration cycle, emphasizing their respective pressure standards.
