Suction pipe diameter selection is based on compressor displacement. Improper pipe size will increase flow resistance and reduce actual cooling capacity of the whole set.
Liquid pipeline layout should avoid unnecessary high elevation. Excessive liquid column pressure brings unstable refrigerant supply to the expansion valve.
xiteliduo Source factory of refrigeration compressor shares pipeline matching reference data for piston refrigeration compressors to assist engineering teams in system design.
Oil return design is critical for piston compressor systems. Pipeline slope must follow specified direction to ensure lubricating oil flows back smoothly to the crankcase.
Long-distance suction pipelines need heat preservation. Uninsulated pipes cause suction superheat to rise sharply and push up compressor exhaust temperature.
Vibration isolation measures are required at the compressor outlet. Flexible connecting joints prevent vibration from transmitting to rigid pipelines and weld seams.
Branch pipelines for multi-temperature cold storage need independent throttle control. Separate liquid supply prevents load fluctuation of one cold room from affecting other zones.
Non-condensable gas accumulation points should be reserved at pipeline high points. Air discharge ports help remove residual gas after vacuuming before refrigerant filling.
Pipeline welding quality directly affects leakage risk. Poor welding joints become the most frequent positions of refrigerant leakage in piston compressor systems.
For parallel piston compressor units, oil balance pipes are necessary. This structure keeps consistent oil level among multiple compressors during variable load operation.
Pipeline support spacing must comply with design standards. Overlong unsupported pipe sections produce extra stress under low temperature shrinkage.
Salt spray coastal projects require anti-corrosion treatment for all refrigeration pipelines. Surface coating slows metal corrosion speed under high humidity and salt fog.
Suction filter installation protects piston internal components. It intercepts metal debris and impurities before refrigerant enters the compressor cylinder.
Exhaust pipeline should avoid excessive bends. Too many elbows increase exhaust pressure and raise power consumption of the piston compressor.
The pipeline near compressor should reserve maintenance space. Sufficient space makes valve replacement and component inspection convenient in later overhaul.
Refrigerant filling ports need to be installed at designated positions. Wrong installation positions will bring difficulty to charging and pressure testing.
Pressure testing must be carried out after pipeline installation. Pressure holding test can detect hidden leakage points before the whole system vacuuming.
Liquid hammer risk should be considered during pipeline layout. Avoid designing pipelines that may cause liquid refrigerant to flow back into compressor cylinder.
Insulation layer thickness matches local ambient temperature. In high-temperature regions, thicker insulation reduces heat infiltration into the refrigerant pipeline.
Pipeline labels should mark refrigerant flow direction and pressure level. Clear labels help maintenance staff quickly judge system status during on-site inspection.
After long time operation, pipeline insulation may age and crack. Regular inspection prevents heat gain and condensation dripping inside the machine room.
The pressure relief pipeline of safety valve must lead to outdoor safe area. Direct discharge inside machine room brings potential safety hazards.
Expansion joint selection takes low temperature contraction into account. Rigid pipelines without expansion joints may crack under temperature cycling.
The suction superheat of R404A system is affected by pipeline heat gain. Too much heat infiltration will push superheat beyond the 6K-10K target range.
