Suction Line Accumulators Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12844
Jlab Export is a leading Suction Line Accumulators Manufacturer,and suppliers in India
A suction line accumulator is a small vessel in the suction line, just before the compressor. It catches liquid refrigerant and oil coming back from the evaporator, lets the liquid boil off and passes on vapour, so liquid does not reach the compressor. This accumulator has 1/2 in connections.

Practicals with the Suction Line Accumulator
Heat pumps are the usual place to see an accumulator at work, because liquid can flood back each time the system reverses or comes out of defrost. On the Mechanical Heat Pump Test Rig, students trace the suction line from the evaporator to the compressor and mark where an accumulator belongs.
In the fitting exercise they braze the accumulator into a suction line, upright and the right way round. Nitrogen flows through the pipe from a Nitrogen Flow Regulator Meter For Brazing while they work. After charging, they measure suction superheat with The Complete A/C Diagnostic Tool. A very low superheat shows that liquid is leaving the evaporator.
Frequently Asked Questions
Where should a suction line accumulator be fitted?
In the suction line between the evaporator and the compressor, as close to the compressor as practical. On a heat pump it goes between the reversing valve and the compressor suction. Mount it upright and do not swap the inlet and outlet.
How does the oil get back to the compressor?
Liquid and oil collect at the bottom of the shell. Most accumulators have an outlet U-tube with a small bleed hole near the bottom. It draws oil and a little liquid back into the suction gas slowly, at a rate the compressor can handle.
Which systems need an accumulator?
Heat pumps, systems with hot gas defrost, and any unit where liquid can flood back at start-up or at low load. A system with a well-set expansion device and a steady load may run without one.
How is it different from a liquid receiver?
A Liquid Receiver stores liquid in the liquid line after the condenser. An accumulator sits on the low side, before the compressor, and traps liquid that should not be there. Both are vessels, but they sit on opposite sides of the system.
