Air Conditioning Repair Certification (ETI) 2025 – 400 Free Practice Questions to Pass the Exam

A liquid recovery system is primarily designed to manage the recovery of liquid refrigerant from an air conditioning or refrigeration system. The correct answer highlights that the main function is to trap liquid refrigerant, ensuring that it is efficiently recovered while minimizing the processing of vapor. This is crucial for maintaining the integrity and efficiency of the refrigerant cycle, as liquid refrigerant can be effectively stored and transported without allowing vapor to escape, which can lead to environmental concerns or inefficiencies in the system.

When refrigerant is recovered in its liquid state, it can be reused or properly disposed of, maintaining the system's performance and safeguarding the environment. This process is essential during maintenance or repairs, where refrigerant management is required to prevent leaks and reduce the overall impact on the atmospheric conditions.

Although other functions like filtering contaminants or measuring refrigerant flow are important in the overall maintenance and management of HVAC systems, they are not the primary purpose of a liquid recovery system. The focus of such a system is specifically on handling liquid refrigerant to ensure proper recovery and efficiency.
