id071100700500

Purpose

• The accumulator separates the gas-liquid 2 phase refrigerant into the gaseous refrigerant and the liquid refrigerant to prevent excessive liquid refrigerant from flowing to the electric compressor.

Function

• The accumulator separates excessive oil in the liquid refrigerant to maintain the oil amount of the refrigerant cycle properly.

Structure/construction

• The accumulator consists of the following parts.

― Tank

― Cup

― Tie wrap

― Desiccant

― Inner pipe

― Outer pipe (with oil return hole)

― Filter

Operation

• The gas-liquid 2 phase refrigerant input from the refrigerant inlet is separated into the gaseous refrigerant and the liquid refrigerant.

• The separated liquid refrigerant is accumulated in the lower part of the tank.

• The separated gaseous refrigerant is sent to the refrigerant outlet as follows.

1. Upper part of outer pipe (1)

2. Lower part of inner pipe (2)

3. Internal part of inner pipe (3)

• When the gaseous refrigerant is sent from the refrigerant inlet to the refrigerant outlet, a part of the liquid mixed with the liquid refrigerant and oil from the oil return hole and mixes with the gaseous refrigerant to supply oil required for lubrication.
