机房精密空调的日常维护与主要故障处理

精密空调日常维护管理与主要故障处理一、前言机房精密空调机广泛适用于计算机机房、程控交换机机房、卫星移动通讯站、大型医疗设备室、实验室、测试室、精密电子仪器生产车间等高精密环境，这样的环境对空气的温度、湿度、洁净度、气流分布等各项指标有很高的要求，必须由每年365天、每天24 小时安全可靠运行的专用机房精密空调设备来保障。

二、精密空调的结构及工作原理精密空调主要由压缩机、冷凝器、膨胀阀和蒸发器四大部件组成。

一般来说空调机的制冷过程为：压缩机将经过蒸发器后吸收了热能的制冷剂气体压缩成高压气体，然后送到室外机的冷凝器；冷凝器将高温高压气体的热能通过风扇向周围空气中释放，使高温高压的气体制冷剂重新凝结成液体，然后送到膨胀阀；膨胀阀将冷凝器管道送来的液体制冷剂降温后变成液、气混合态的制冷剂，然后送到蒸发器回路中去；蒸发器将液、气混合态的制冷剂通过吸收机房环境中的热量重新蒸发成气态制冷剂，然后又送回到压缩机，重复前面的过程。

精密空调的构成除了上面介绍的压缩机、冷凝器、膨胀阀和蒸发器外，还包括：风机、空气过滤器、干燥过滤器、加湿器、加热器、视液镜、储油罐、电磁阀等，因此我们在日常的机房管理工作中对精密空调的管理和维护，主要是针对以上部件去维护的。

三、精密空调的日常维护管理1、控制系统的维护对空调系统的维护人员而言，在巡视时第一步就是看空调系统是否在正常运行，因此我们首先要做以下的一些工作。

1）从空调系统的显示屏上检查空调系统的各项功能及参数是否正常；2）如有报警的情况要检查报警记录，并分析报警原因；3）检查温度、湿度传感器的工作状态是否正常；4）对压缩机和加湿器的运行参数要做到心中有数，特别是在每天早上的第一次巡检时，要把前一天晚上压缩机的运行参数和以前的同一时段的参数进行对比，看是否有大的变化，根据参数的变化可以判断IT设备运行状况是否有较大的变化，以便合理地调配空调系统的运行台次和调整空调的运行参数。

当然，对目前而言有些比较老的空调系统还不能够读出这些参数，这就需要晚上值班的工作人员多观察和记录。

If the value of the pressure gauge needleremains unchanged (maintained at -0.1MPa), it proves that the system is well sealed and can be filled withrefrigerant.⚫Figure 5-4Maintain pressureStep 4 Refrigerant charge.After the system pressure is maintained, remove the vacuum pump from the pipeline, and connect the pipeline to the refrigerant tank to charge the refrigerant.1. Move the gas pipe connecting the vacuum pump to the refrigerant tank and tighten it, thenloosen the connection of the middle pipe of the pressure gauge by 4-5 turns.⚫Figure 5-5Connect to the refrigerant tank2. Turn on the switch of the refrigerant tank, let the gas pour into the pipe and rush out from theconnection. The process lasts for about 10 seconds, and then tighten the pressure gaugeconnection so that the air in the pipe is discharged to the outside.3. After exhausting the air from the pipeline, the refrigerant charge is started. Please turn therefrigerant tank upside down when charging, and you must use an electronic scale to ensurethe quality of the refrigerant charged.⚫Figure 5-6Charge refrigerant4. After the refrigerant charging is completed, close the valve on the low pressure port side of thepressure gauge, do not remove the pipeline connection for the time being, and perform thepower-on operation and refrigeration operation.⚫Figure 5-7Close the low pressure charging value4 Power On and Test the Air ConditionerPower on the unit and adjust the cooling point of the unit to below the temperature detected by the indoor sensor. Run the unit for half an hour to see if the cooling of the unit is operating normally.⚫When the ambient temperature reaches the cooling point of the air conditioner, the air conditioner will automatically enter the cooling state when the air conditioner ispowered on for 3 minutes.⚫If the ambient temperature does not meet the cooling conditions, you can turn on the load to make the air conditioner enter the cooling state.After the unit is operating normally, quickly remove the high and low pressure connections. A small amount of refrigerant will be sprayed out during the dismantling process, which is normal. Screw the bonnet back to complete the refrigerant charging.⚫Figure 5-8Remove the refrigerant charging port connection5 Reinstall the Air Conditioner Into the CabinetLift the air conditioner and slowly push it into the cabinet from the front, avoiding the air conditioner limit blocks on the left and right sides of the cabinet until the mounting flange is close to the cabinet column, and then install the air conditioner in the reverse order according to 2 Disassemble the Unit.1. 简介1.1 前言注意：任何针对本产品的操作必须由专业的工程技术人员进行。

故障的诊断
汽车空调出现故障时，重要的是要确切诊断故障，实施适当的修理。确诊症状时，请参考 “冷媒充填”的内容。
1 冷冻回路气体不足
在视窗看得见气泡，如右表-1，高压、低压的压力都不足时，可以确定是气体不足。这时即使补充冷媒，仍会气体不足。气体总是不足现象发生时，可以考虑是从接管的接头等部位发生了泄漏。气体泄漏时，油也会一起泄漏，请注意察看附近是否有油渗漏出来。另外，用检漏仪等工具可以容易地检测出泄漏的地方。

结霜，是蒸发器上快速冷却的空气中的水份被冻结成霜凝集在散热片上，引起热交换能力下降的现象。在A/C使用中，吹出的温度虽然很冷，但吹出口的风量阵阵减弱，好象制冷不足的样子出现时，要怀疑是结霜了。风量微弱时，将A/C开关打到OFF，将送风马达开到最大，要是出现大量且连续的雨水样时，要考虑是结霜。因此，为防止结霜，恒温器的功能要发挥好。恒温器检测蒸发器出口的温度，或是散热片的温度，具有不让温度下降到蒸发器结霜的功能。至于为何出现风量微弱、散热片表面不干净、恒温器状态不良、感温筒的接触不良（松动）等的原因，使空气中的水份在蒸发器表面凝结成霜而阻住风口，首先要重点检查图示这些地方。
