1、為了保證機器處于被正常潤滑的狀態，我們必須要注意保證制冷壓縮機里面的潤滑油不能低于視油鏡油位的三分之一

1, in order to ensure that the machine is in the normal lubrication state, we must pay attention to ensure that the lubricating oil in the refrigerating compressor can't be lower than the oil level of the oil mirror 1/3.

2、要隨時留意制冷壓縮機的排氣溫度，根據具體的制冷劑然后依據對應的壓力表來衡量，比如：常用的R22制冷劑其排氣溫度就不得高于145攝氏度

2, pay attention to the exhaust temperature of refrigerating compressor at any time. According to the specific refrigerant and then according to the corresponding pressure gauge, for example, the exhaust temperature of the commonly used R22 refrigerant should not exceed 145 degrees Celsius.

3、整個制冷系統的的吸氣溫度相對于蒸發溫度而言必須要高出來5至15攝氏度。

3. The suction temperature of the whole refrigeration system must be 5 to 15 degrees Celsius higher than the evaporation temperature.

4、一般情況下吸氣溫度和庫溫相差0-5攝氏度是很正常的;

4, general suction temperature and temperature difference of 0-5 degrees Celsius is normal;

5、一個正常的制冷系統必須要保證油分離器能夠自動的正常回油;

5. A normal refrigeration system must ensure that the oil separator can automatically return the oil automatically.

6、正常系統的油溫應該保持在40攝氏度到60攝氏度之間，如果在系統不能自我保證的情況下，則需要配備相應的曲軸加熱器;

6, the normal system oil temperature should be kept between 40 degrees Celsius and 60 degrees Celsius. If the system can't guarantee itself, it needs to have the corresponding crankshaft heater.

7、制冷壓縮機的的油壓一定要比吸氣壓力高出來0.15MP到0.3MP之間

7. The oil pressure of the refrigeration compressor must be higher than the suction pressure between 0.15MP and 0.3MP
