Cold storage library system maintenance scheme
1, unit operation, often should observe the oil level and oil return of compressor and the purity of the oil, and found that the oil level of oil dirty or decline to solve in time, lest cause poor lubrication.

2, chillers for: want to often clean the air cooling unit to keep the good state of heat transfer. For water chilling unit, often should check the cooling water turbidity degree, such as the cooling water is too dirty, should be replaced. Check the water supply system with and without bubble, take, drop, leakage problem. Water pump work is normal, the valve switch is effective, the cooling tower. The fan is normal. For air cooling units: check condenser fouling problems, to keep clear of in time scale.

3, for air cooling machine evaporator: always check the defrosting, defrosting is timely and effective, can affect the cooling effect, causes the liquid cooling system.

4, often observe the compressor running state, check the exhaust temperature, the change garments according to the runtime, to pay special attention to the running state of the system, adjust the system for fluid volume and condensing temperature.

5, and carefully listen to the compressor, cooling tower, water pump, or condenser fan running sound, found abnormal processing, at the same time check the compressor, the vibration of the exhaust pipe and anchor.

6, the compressor maintenance: early internal system cleanliness is poorer, running after 30 days to change a frozen oil and filter drier, change again after running for half a year (according to the actual situation and decide). For cleanliness higher system, running for half a year later will also change a frozen oil, and dry filters, as the case may be in the future.

7, unit operation, often should observe the oil level of the compressor and the purity of the oil and oil, found the oil level of oil dirty or decline to solve in time, lest cause poor lubrication.

12, the compressor maintenance: early internal system cleanliness is poorer, running after 30 days to change a frozen oil and filter drier, change again after running for half a year (according to the actual situation and decide).
