. 初期运转冰水机:要经常观察压缩机的油面、回油情况及油的清洁度，发现油脏或油面下降要及时更换或添加，以免造成润滑不良而影响冰水机运行。 1. Initial operation of the ice water machine: Observe the oil level, oil return and cleanliness of the compressor frequently, and find that the oil is dirty or the oil level has to be replaced or added in time to avoid poor lubrication and affect the operation of the ice water machine
对于风冷冰水机:要经常清洗风冷器使其保持良好的换热状态，经常检查冷凝器是否出现结垢问题，要及时清除水垢。 2. For air-cooled ice water machine: Always clean the air cooler to maintain a good heat exchange state, check the condenser for scale problems frequently, and remove the scale in time.
For water-cooled ice water machine: Always check the turbidity of the cooling water. If the cooling water is too dirty, replace it. Inspect the water supply system for running, dripping, dripping, and leaking water. Whether the pump works normally, whether the valve switch is effective, and whether the cooling water tower and fan are normal.
对于风冷机式的蒸发器：要经常检查除霜情况，除霜是否及时有效，会影响制冷效果，导致制冷系统回液。 3. For air-cooled evaporator: Check the defrost frequently. Whether the defrost is effective in time will affect the cooling effect and cause the liquid return of the refrigeration system.
经常观察压缩机运行状态，检查其排气温度，在换季运行时，要特别注意系统的运行状态，及时调整系统供液量和冷凝温度。 4. Frequently observe the operating status of the compressor and check its exhaust temperature. When changing the season, pay special attention to the operating status of the system and adjust the system's liquid supply and condensation temperature in time.
仔细倾听压缩机，冷却塔、水泵或冷凝器风机运转声音，发现异常及时处理，同时检查压缩机、排气管及水泵的振动情况。 5. Listen carefully to the operating sound of the compressor, cooling tower, water pump or condenser fan. If abnormality is found, deal with it in time, and check the vibration of the compressor, exhaust pipe and water pump.
. 对压缩机的维护：初期系统内部清洁度较差，在运行30天后要更换一次冷冻油和干燥过滤器，在运行半年之后再更换一次（要根据实际情况而定）。 6. Maintenance of the compressor: the initial cleanliness of the system is poor. After 30 days of operation, the refrigeration oil and drying filter should be replaced once, and replaced after half a year of operation (depending on the actual situation). For systems with high cleanliness, the refrigeration oil and drying filter should be replaced once after half a year of operation, depending on the situation later.
