Condenser transfers compression heat to cooling medium; fouling layer forms thermal resistance, elevates condensing pressure, reduces cooling capacity and increases power consumption.
When condenser heat transfer coefficient drops by more than 20% compared with clean state, fouling cleaning is required; fouling thickness over 0.3 mm will obviously reduce heat exchange efficiency.
Xiteliduo reciprocating compressor control system calculates real-time condenser heat transfer coefficient based on pressure and temperature readings to assess fouling degree.
Small 4-cyl reciprocating refrigeration compressor water-cooled condenser fouling mainly consists of calcium carbonate scale; hard scale adheres tightly to inner tube surface.
Medium 4-cyl reciprocating refrigeration compressor air-cooled condenser fouling is mostly dust and fiber; surface dust layer can be removed by compressed air online blowing.
Large 4-cyl reciprocating refrigeration compressor shell-and-tube condenser needs periodic chemical cleaning; chemical solution formula must avoid corrosion to tube material.
Large 6-cyl reciprocating refrigeration compressor multi-condenser parallel layout allows single condenser isolation cleaning; whole refrigeration system does not need full shutdown.
Many plant teams only clean condenser after high condensing pressure alarm. Delayed cleaning increases unit annual power consumption by 33%.
Single-unit two-stage refrigeration compressor high-stage condenser undertakes most heat rejection task; fouling on high-stage condenser has larger impact on system performance.
Cascade unit high-stage reciprocating refrigeration compressor condenser works at higher temperature; high temperature accelerates scale deposition rate on water-cooled type.
