精密空调设备技术参数选型原则
精密空调设备技术参数选型原则机房专用空调作为提供严格温度、严格湿度及洁净度的重要设备，是保证用户获得一个有严格温度、严格湿度及洁净度控制的长期安全稳定工作环境的重要设备，是保护用户的有效投资和无形资产的重要设备。
因此正确的选型合理的设备配置是为用户发挥有效投资的依据。
现按设计院的设计提供设备型号配置和设备说明。
根据国家计算机房建设标准：GB50174-93及《电子计算机机房设计规范》为依据，按规定A类机房空气循环次数为不能低于30次每小时，机房越大设备越多要求气流循环的越快，这是保证气流强制快速循环才能迅速有效地把设备所产生的热量平衡掉的保证。
对于一个机房来说，正确的选择精密空调设备包括如下几个问题。
一、根据机房的总热量（建筑结构热量＋设备总热量）和保证机房环境所必须的气流循环次数，选择合适的设备容量（考虑一定的设备备份）二、根据整个建筑物的整体结构选用合适的空调冷却方式，选用风冷型空调还是选用水冷型空调还是选用其他形式的空调，要综合考虑选用正确的方式是保证空调今后长期平稳运行的要素。
三、结合机房自身结构特点及用户要求，合理地选用上下送风方式。
根据以上三点阐述精密空调选型理论依据。
四、节能和今后运行费用的综合考虑。
一）根据机房的总热量（建筑结构热量＋设备总热量）和保证机房环境所必须的气流循环次数，选择合适的设备容量（考虑一定的设备备份）如：机房面积为Xm²，机房净高Hm，要求下送风机型。
（如果采用下送风机型，为保证出风的效果静电地板的高度应在300㎜以上。
）（1）由公式n（循环次数）= F（风量）V（房屋体积）得出被控房间所需的循环风量为F=30 ※X ※H= X m³/h（2）计算被控机房间所需的冷负荷估算：综合计算被控机房间所需机房所需冷量的原则为：房屋结热构负荷+设备热负荷+设备备份。
根据《电子计算机机房设计》一书为依据进行计算。
房屋结构热量按国家标准每平方（120～180）W计算，一般选取中间值为150W。

Thevacuum degree of the system is required to be below 35Pa.⚫Figure 5-3Power on the vacuum pumpStep 3 Maintain pressure on the system.After the vacuum is completed, power off the vacuum pump, close all the pressure gauges and tighten theconnection between the pressure gauge and the vacuum pump. Keep the pressure of the system for 20-30 minutes and observe whether the pointer of the pressure gauge does not move. 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。
