Visual inspection is the first step of acceptance. Check compressor foundation fixing bolts, shock absorber installation and all pipeline welding seams. Misaligned piping creates extra stress and risk of refrigerant leakage after long run.
Electrical acceptance covers wiring tightness, insulation test and protection function test. Phase loss, over-current and high pressure protection must trigger correctly during simulation test.
Pressure holding test is performed on refrigerant circuit. Maintain system pressure for minimum 24 hours, pressure drop should be less than 0.02MPa to prove no leakage point.
Start-up commissioning includes 4-hour continuous trial run. Engineers log suction pressure, discharge pressure, oil temperature, motor current and cold room temperature change every 30 minutes. All indicators must stay within design scope.
Oil level inspection under stable running status is required. Oil level should stay in the middle sight glass range; too high or too low oil level needs adjustment.
xtldcool supplies standardized acceptance checklist for contractors and end users. The document records all test data and becomes part of project delivery file.
After acceptance, operators receive on-site operation training. Training covers normal startup procedure, alarm judgment and simple troubleshooting of piston refrigeration compressor.
