Accumulator HVAC: Description and Operation
Accumulator-Interior Parts
Description
Connected to the evaporator outlet pipe, the sealed accumulator assembly acts as a refrigerant storing container receiving vapor and some liquid and
refrigerant oil from the evaporator.
Operation
At the bottom of the accumulator is the desiccant which acts as a drying agent for moisture that may have entered the system. This desicant is
specifically for R134a. An oil bleed hole is also located near the bottom of the accumulator outlet pipe to provide an oil return path to the compressor.
