中央空调冷水机组的保养有两种：一种是故障保养，只有在发生故障时才进行修理，平时并不特别费心；另一种预防性保养，为了能使机械处于良好的运转状态而经常有计划地进行保养，具体来说，这是一种实行定期检查，更换零部件，保证不出现运转故障的一种管理方法。前一种方法在机械设备保持全新状态时，不必支付保养费用，经济性似乎较好，但是随着机组的使用年限增加，出现事故的危险性增加，修理费用也显著增加。后一种预防性保养法事先考虑到机械运转时的磨损和性能变化，据此制定保养计划，使机械的老化局限于*小范围之内。从新机器开始就实行这种有计划的保养管理，**好像要多花费一些保养费，但是机械寿命延长，以后出现大故障的可能性减小，这样总的保养费反而比较低。机组的运行寿命取决于运行状态、维护情况，制冷机组设计和制造的运行寿命在15年以上，条件是按照维护要求进行经常性维护和定期更换易损件。  运转管理人员必须了解下列事项：检查什么（检查项目），何时检查（检查频繁程度），为何检查（检查目的），如何进行检查（检查方法），这个数据是否正确（判断结果），情况恶化怎么办（对策与处理）。  为此在记录机器每日运转状态和定期检查时拆开情况时，如果能彻底理解上述六点，就能掌握记录数据所包含的内容，看出微小的故障征状，直接采取对策与处理方法，事后防止发生重大事故，同时对今后制定保养计划也有好处。

Freezing means lowering the temperature and allowing the object to solidify and freeze. Also called "refrigeration", it is the application of thermodynamics principle, the method of artificially manufacturing low temperature, refrigerator and air conditioner are all based on the principle of refrigeration. From the chemical point of view, it is generally used a gas with a high critical point, pressurized and liquefied, and then it is vaporized and absorbed, and this process is repeated. When liquefying, it is exothermic in other places, and when it is vaporized, it absorbs heat to the required range. . Central air conditioning, screw chiller, air-cooled module heat pump air conditioner, brine cryogenic machine, heat pump hot water project, constant temperature and humidity air conditioning, precision air conditioning, quick freezing, freezing, cold storage, clean technology and purification system engineering design and installation business.
