Discharge Line Pipelines
When the compressor discharge pair assigned to bypass capacitor, capacitor may be warmer than the compressor in the part of the cycle. When this happens, the refrigerant vapor can move back from the condenser, It will condense the head of the piston compressors.
If the compressor relief valve leakage of liquid refrigerant will collect in the cylinders. This can lead to the compressor for pumping liquid refrigerant at start-up. This condition will reduce lubrication for the pistons and valves. He could even break them. If the valves of the compressor does not leak, the liquid refrigerant in the cylinder head can cause damage to the compressor start-up. This is due to the dynamic hydraulic pressure at the compressor head and pipelines. Check valve is installed in the discharge line near the capacitor will resolve this potential danger...
