在开启制冷设备前需要对压缩机的运行状态是否正常，接下来检查制冷系统管路上各手动阀门的启闭情况是否正确。检查各设备上的安全阀、压力表、液面指示器等前面的截止阀及各均压阀是否打开。但充注阀和集油器、放空气器上放汕阀、放空气阀等应关闭。检查储液器等设备中制冷剂液面是否在要求的范围内。

 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.

如何保持制冷设备处于安全的运行环境

运行环境的安全度决定制冷设备的具体使用寿命，为达到保持制冷设备稳定性，在实际的安装过程中，首先需要保障制冷设备的用电安全，小编建议安装制冷设备的过程中，需要为制冷设备独立安装电源设备，并且有效的控制安全电压与电流，达到满足制冷设备正常运行的目的，同时单独的提供电源，能够避免各类过载问题而影响制冷设备的正常运行，即便处于长期的运行状态，同样不会出现任何的安全问题。

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.

保持干净卫生的运行环境

保持制冷设备安装环境的卫生，能够达到延长制冷设备寿命的目的，如果制冷设备处于较为恶劣的环境内，对于关键的配件寿命影响非常大，尤其针对很多水冷式制冷设备，对于环境的要求更高，保持干净的使用环境，对于减少制冷设备产生的污垢为题，起到至关重要的作用。

 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.

利用氟利昂降温需谨慎保养

很多制冷设备设备通过氟利昂达到降低环境温度的目的，因此在实际的使用过程中，使用者可以通过注入高品质冷媒的方式达到提高降温效果。

 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.
