　　What tests should be done before the refrigeration chiller leaves the factory?

　　The refrigeration cooler needs to undergo the following tests before leaving the factory:

　　1. Appearance inspection: Check whether the appearance of the cooler is intact and whether there are obvious deformations, scratches, or cracks.

　　2. Electrical performance test: By connecting the power supply, test the electrical performance of the cooler, including whether the parameters such as current, voltage, and power comply with regulations.

　　3. Refrigeration performance test: Use standard testing methods and equipment to test the refrigeration performance of the cooler, including refrigeration capacity, refrigeration efficiency, and refrigerant cycle.

　　4. Pressure testing: Conduct pressure testing on the pipes and containers of the cooler to ensure that they can withstand the pressure under normal working conditions.

　　5. Vacuum test: Ensure that the vacuum inside the cooler meets the requirements to ensure its normal operation and long-term stability.

　　6. Noise test: Test the noise level of the cooler during operation to ensure that it is within the specified range and does not cause excessive interference to the environment and users.

　　7. Safety performance test: Test the safety performance of the cooler, including whether the functions of leakage protection, overload protection, etc. operate normally.

　　8. Inspection of signs and markings: Check whether the signs and markings on the cooler are complete, clear and visible, and comply with relevant standards and regulations.

　　The above are common testing items for refrigeration coolers before leaving the factory. Through these tests, it can be ensured that the quality and performance of the cooler meet the requirements, enabling it to operate safely and reliably during use.
