Fluid reservoir function - GF83.40-P-2122-01GI

Function 

The liquefied refrigerant enters the fluid reservoir under pressure and flows through a stainless-steel fabric layer to the filter block. The filter block's pores are matched exactly to the molecular size of the refrigerant. Thus the refrigerant can flow through the filter block.

All other matter, primarily water, is held back by this molecular filter and deposited. The cleansed refrigerant then flows through a rising pipe to the expansion valve.

Whenever the system is opened, the fluid reservoir should be replaced because of the water which has collected there in the meantime.
