Each startup of piston compressor creates large inrush current and instant mechanical impact on valve plate, piston ring and crankshaft. The impact force at startup is several times higher than normal stable running load.
The recommended limit is maximum 6 to 8 start cycles per hour for semi-hermetic piston refrigeration compressor. More frequent startups will greatly shorten the lifespan of wearing parts.
Small cold storage with low thermal load is prone to frequent cycling. Installing thermal mass or increasing compressor capacity unloading stage can prolong running time and reduce start-stop frequency.
Pressure differential control instead of simple temperature switch helps reduce frequent startup. Pressure-based control avoids rapid on-off triggered by tiny temperature fluctuation caused by cold storage door opening.
When piston compressor starts frequently, motor winding temperature rises repeatedly. Thermal fatigue gradually degrades insulation material, and the risk of motor burnout increases significantly after years of operation.
xtldcool engineers optimize control parameters during commissioning. We adjust differential setting and capacity unloading function to keep startup frequency within safe range for cold storage piston compressor.
If frequent start-stop cannot be eliminated by parameter adjustment, system design modification is required, such as adding liquid receiver or reselecting proper compressor displacement.
