Where is the suction accumulator typically located in a refrigeration system?

The suction accumulator is typically located on the low side just before the compressor in a refrigeration system. Its primary function is to store and regulate the refrigerant vapor that is drawn from the evaporator. By being positioned close to the compressor, the accumulator serves to smooth out any fluctuations in vapor flow and ensures that the compressor receives a steady supply of refrigerant vapor. This placement also helps to prevent liquid refrigerant from entering the compressor, which could cause damage or inefficiency.

In essence, the accumulator acts as a buffer to collect excess vapor and help manage the refrigerant flow, enhancing the reliability and efficiency of the refrigeration system. Its strategic location on the low side is crucial for optimal system function and compressor protection.
