ESCO Air Conditioning Practice Exam

A liquid line filter-drier should be placed between the

1. Accumulator and the Compressor

2. Compressor and the Condenser

3. Condenser and the Metering device

4. Evaporator and the Accumulator

The correct answer is: Accumulator and the Compressor

A liquid line filter-drier should be placed between the Accumulator and the Compressor because it helps in filtering out contaminants and moisture present in the refrigerant liquid before it enters the compressor. This location assists in protecting the compressor from potential damage caused by these contaminants, ensuring the efficient operation and longevity of the system. Placing the liquid line filter-drier between the compressor and the condenser, condenser and the metering device, or evaporator and the accumulator would not provide the same level of protection for the compressor as having it located between the accumulator and the compressor.
