Question

A dryer is generally installed with other equipment in a commercial Freon compressor system. The recommended location of this dryer is on the____________.

1) high-pressure line between condenser and receiver
2) suction line between evaporator and compressor
3) discharge line between compressor and condenser
4) liquid line between receiver and expansion valve

Answer 1

The dryer in a Freon compressor system should be installed in the liquid line between the receiver and the expansion valve to ensure the refrigerant is dry and clean, protecting the expansion valve.

Step-by-step explanation:

In a commercial Freon compressor system, a dryer is essential for removing moisture and contaminants that could cause freezing, corrosion, or other issues within the system. The recommended location for installing the dryer is in the liquid line between the receiver and the expansion valve. This ensures that the refrigerant is dry and clean before it passes through the expansion valve and moves into the evaporator. Placing the dryer here protects the expansion valve, which can be sensitive to particles and moisture in the refrigerant.
