在開啟制冷設備前需要對壓縮機的運行狀態是否正常，接下來檢查制冷系統管路上各手動閥門的啟閉情況是否正確。檢查各設備上的安全閥、壓力表、液面指示器等前面的截止閥及各均壓閥是否打開。但充注閥和集油器、放空氣器上放汕閥、放空氣閥等應關閉。檢查儲液器等設備中制冷劑液面是否在要求的范圍內。

 It is necessary to do a good job of inspection before using the refrigeration equipment。Before opening the refrigeration equipment, we need to know whether the compressor's running state is normal. Next, check whether the opening and closing of each manual valve on the refrigeration system pipeline is correct. Check whether the front cut-off valves and the pressure relief valves are open on the safety valves, pressure meters, level indicator and so on on each equipment. But the filling valve and the oil collector, the air discharge valve, the air valve and so on should be closed. Check whether the refrigerant liquid level in the liquid storage equipment and other equipment is within the required range.

如何保持制冷設備處于安全的運行環境

運行環境的安全度決定制冷設備的具體使用壽命，為達到保持制冷設備穩定性，在實際的安裝過程中，首先需要保障制冷設備的用電安全，小編建議安裝制冷設備的過程中，需要為制冷設備獨立安裝電源設備，并且有效的控制安全電壓與電流，達到滿足制冷設備正常運行的目的，同時單獨的提供電源，能夠避免各類過載問題而影響制冷設備的正常運行，即便處于長期的運行狀態，同樣不會出現任何的安全問題。

How to keep the refrigeration equipment in a safe operating environment。The safety of the running environment decides the specific service life of refrigeration equipment, refrigeration equipment to maintain stability in the actual installation process, first of all need to use electric safety of refrigeration equipment, Xiaobian recommended refrigeration equipment installation process, need power supply device for refrigeration equipment installation and safety control independently, the voltage and current effective meet the refrigeration equipment, normal operation, and separate power supply, can avoid all kinds of overload problems which influence the normal operation of the refrigeration equipment, even in the long running state, also does not appear any security issues.

保持干凈衛生的運行環境

保持制冷設備安裝環境的衛生，能夠達到延長制冷設備壽命的目的，如果制冷設備處于較為惡劣的環境內，對于關鍵的配件壽命影響非常大，尤其針對很多水冷式制冷設備，對于環境的要求更高，保持干凈的使用環境，對于減少制冷設備產生的污垢為題，起到至關重要的作用。

 keep clean and hygienic operating environment。Keep the refrigeration equipment installation environment hygiene, can prolong the life of the refrigeration equipment, if refrigeration equipment in harsh environment, impact on key parts of life is very large, especially for a lot of water-cooled refrigeration equipment, the environment is more demanding, clean environment, to reduce production of refrigeration equipment on the dirt the play a crucial role.

利用氟利昂降溫需謹慎保養

很多制冷設備設備通過氟利昂達到降低環境溫度的目的，因此在實際的使用過程中，使用者可以通過注入高品質冷媒的方式達到提高降溫效果。

 Use freon to keep the cooling down carefully。Many refrigeration equipments achieve the goal of reducing the ambient temperature through Freon. Therefore, in the actual application process, users can increase the cooling effect by injecting high quality refrigerant.
