Question

o a storage spot for excess liquid refrigerant
o a storage spot for excess gas refrigerant
o always found on an air conditioner
o never found on a heat pump
o located just downstream of the expansion device

Explanation:

An accumulator stores excess liquid refrigerant in a refrigeration system to prevent liquid - slugging of the compressor. It is not for excess gas refrigerant. It is not always found on an air - conditioner and can be found on heat pumps. It is located upstream of the compressor, not downstream of the expansion device.

Answer:

A. a storage spot for excess liquid refrigerant
