Receiver Dryer: Description and Operation
RECEIVER DRYER
The receiver/dryer (5) performs four functions:
-
As the quantity of refrigerant circulated varies depending on the refrigeration cycle conditions, sufficient refrigerant is stored for the refrigeration
cycle to operate smoothly in accordance with fluctuations in the quantity circulated.
-
The liquefied refrigerant from the condenser is mixed with refrigerant gas containing air bubbles. If refrigerant containing air bubbles is sent to the
expansion valve, the cooling capacity will decrease considerably. Therefore, the liquid and air bubbles are separated and only the liquid is sent to
the expansion valve.
-
The receiver/dryer utilizes a filter and dryer to remove the dirt and water mixed in the cycling refrigerant.
-
The sight glass, installed atop the receiver/dryer, show the state of the refrigerant.
A receiver/dyer may fail due to a restriction inside the body of the unit.
A restriction at the inlet to the receiver/dryer will cause high pressure.
Outlet restrictions will be indicated by low pressure and little or no cooling. An excessively cold receiver/dryer outlet may indicate a restriction.
The receiver/dryer of this vehicle is made of aluminum with a smaller tank. It has a 300 cc refrigerant capacity.
The refrigerant line connection has a bolt at the block joint, for easy servicing.
