CSM开机操作手册一冷水机组系统管理概述1 系统组成结构CSM在群控系统中的位置：1> CSM的软件运行,向下通过LONWORKS通讯网进行CSM与相关机组控制器之间的通讯，可以通过PC的Web访问和控制。

2> CSM向上能够通过BACnet (标准IP 或Ethernet 协议) 或 Modbus (可选RTU 或基于 RS-485\ RS-232端口的 ASCII)与楼宇自控系统（BAS）进行通讯。

图1 系统框架图2 CSM的组成和功能MT II CSM是由一个硬件平台和一个可用Web UI访问和修改的软件平台所构成：1> 硬件部分包括主处理器，板载I/O和可选的远程I/O。

其中主处理器，板载I/O都安装在CSM的壳体内。

可选的远程I/O包括分布式的I/O 模块，它可以脱离CSM的壳体进行安装。

CSM主处理器中的软件会执行全部的控制功能来管理冷水机和在CSM上全部的I/O及远程I/O模块。

2> CSM的软件平台通过LONWORKS网络与机组控制器进行通讯。

Web UI 包含从CSM上访问的网页，这些网页可以在任何一台装有微软的Internet Explorer并且与CSM的网络端口互联的计算机上访问到。

这种基于浏览器的用户界面是用于修改多机组联控策略所必须的控制参数和设定某些多机组单元控制所必要的机组控制器的参数以及查看系统运行状态。

多机组联控策略使联接在CSM上的所有冷水机组实现自动控制。

CSM为冷水机组提供了如下功能：启停能力，时序安排，次序安排，负载限制控制，系统冷冻水温控制，次级循环水流控制，冷水塔控制，过程报警，报警产生等。

CSM可以控制的冷水机可以全部是离心机，也可以全部是活塞机，也可以全部是螺杆机，抑或是离心机、活塞机、螺杆机的组合。

CSM的型号指明了它所能控制冷水机组的最大数目（如型号为MTII-UC-1-CSM12的CSM最大能控制12台冷水机组）。

安装注：安装和维修必须由受过专业培训，熟悉当地标准和规则并对制冷设备有实际经验的专业人员操作。

到货验收：当设备到达后，按照提货清单仔细检查所有的项目是否齐全，零部件在运输过程中是否损坏。

若有损坏通知运输商并书面提出赔偿要求。

在机组安装之前，必须检查当地所用电源电压，频率等是否适合本机组，到货验收合格后发生的任何损伤，麦克维尔将不承担赔偿责任。

起吊机组安装在防滑枕木上以避免机组发生突发损伤并可用于简单的起吊和移动，在机组定位以前尽可能不要取下枕木，且移动和起吊机组时最好带有枕木。

机组起吊时，必须用缆绳或者链子缚紧在蒸发器和冷凝器起吊孔上起吊。

起吊时必须保护控制柜和机组其它部分不受损伤。

水管1机组进出水口必须安装截止阀便于系统能完成常规维修。

2建议在冷凝器和蒸发器进出水处安装温度计和压力表，便于常规检查和维修机组。

3建议在水泵进水口安装过滤网，避免杂质进入冷凝器和蒸发器。

4在机组和管道连接之前预先检查管路的密封性。

5建议与机组相连的管道安装减振装置，避免将机组振动传递到管路上。

6建议安装符合要求的流动检测装置，如靶式流量计，水压差控制器，并且将它们与机组控制相连。

7由机组来控制冷却水泵，冷冻水泵以及冷却塔风扇的开启和停止，以期获得最好的节能效果和可靠性。

机组启动与停机机组检查机组启动前需要作以下检查：A水路部分A1检查所有的水系统管路，确认蒸发器和冷凝器水路联结无误并且水流方向正确。

A2检查冷却水进水温度传感器和冷冻水出水温度传感器安装位置是否正确，接头是否牢固，温度显示值是否正确。

如果不对，请在TP7控制屏中的“机组设置”项上进行校正。

A3打开所有水阀，开启水泵，检查连接水法兰是否有泄漏，排出冷凝器和蒸发器中的空气。

A4检测蒸发器和冷凝器水侧阻力损失，检查水流开关或水压差控制器是否动作正确。

B电路部分B1断开主断路器，检查电柜的进线是否安全牢固。

B2检查供给机组的电源，其电压波动范围应不超过压缩机铭牌所示额定电压的10%，且相电压不平衡不超过2%。

The small size and light weight in conjunction with its installation flexibility (inside or outside the pressure vessel) make it an ideal choice for aircraft power needs while reducing the challenges associated with other similar products.Highlighted features include short circuit protection, overload capability, low input voltage shut-down, temperature monitoring, reverse polarity protection, a self-resettable over-temperature disable and an optional remote enable (on/off) feature.The TC240 DC/DC converter has a robust Military-rated circular connector and a rugged aluminum case which dissipates heat and provides excellent mechanical strength. It is engineered to require no external cooling and contains no internal fans or cooling methods, which saves energy, reduces weight and allows more flexible installation locations. At only 0.70 pounds, it is lighter and smaller than any other certified solution in the aviation market today.1.2 TECHNICALSPECIFICATIONSElectrical Attributes:Input Voltage: Rated 28VDC nominal, Operating 24 – 32VDC.Input Current (full load): 10 amps max at nominal input voltageOutput Voltage 5 – 18VDC adjustableOutput Power: 240 watts nominalEfficiency: 95%nominalTable 1.1Physical Attributes:Weight: 0.70 lbs (0.32 kg)Dimensions:(not including connector mate) 2.75 inches long x 3.75 inches wide x 1.29 inches high (69.9 mm long x 95.3 mm wide x 32.8 mm high)Mating Connector Kit: 6430240-1 MCIA P/N 9018654 6430240-2 MCIA P/N 9018655Mounting: Base mount – orientation not criticalTable 1.2Qualifications:Certification: FAATSO-C71Environmental Qualification: RTCA DO-160G Environmental Category; See Section 5.2 Altitude: -15,000 feet to +55,000 feetTemperature: -55°C to +70°C (-67°F to +158°F)Table 1.3SECTION 2 PRE-INSTALLATION CONSIDERATIONS2.1 COOLINGThe TC240 product does not require external cooling or contain internal active cooling. Cooling of the unit occurs exclusively through passive conduction through the base or radiated cooling across the metal case. Additional cooling can be realized through convection (exposure to free moving air) or conduction (mounting to a thermally conductive metal surface). These methods are not required to achieve rated performance but can help prevent potential overheating and extend life when the unit is operated at full power or during overload conditions. Specifically, mounting the unit to a metal surface is preferred, but not required.2.2 EQUIPMENTLOCATIONThe TC240 is designed for mounting flexibility, allowing for installation inside or outside the pressure vessel with no requirement for temperature control. In addition to altitude and temperature resistance, the unit is also designed to withstand high levels of condensing humidity. However, installation locations where the unit could be subject to standing or direct water exposure should be avoided. The unit can be mounted in any orientation. Clearance should be provided for the mating connector and may require as much as five inches past the unit connector to allow for back shell access to the connector.OFCABLES2.3 ROUTINGThe wires and cable bundle associated with the unit are heavy gauge wire and carry significant power. Be aware of routing cables near other electronics or with other wire bundles that may be susceptible to high energy flow.Avoid sharp bends in cabling and routing near aircraft control cables. Also avoid proximity and contact with aircraft structures, avionics equipment, or other obstructions that could chafe wires during flight and cause undesirable effects.2.4 LIMITATIONSThe conditions and tests for TSO approval of this article are minimum performance standards. Those installing this article, on or in a specific type or class of aircraft, must determine that the aircraft installation conditions are within the TSO standards. TSO articles must receive additional installation approval prior to being operated on each aircraft. The article may be installed only according to 14 CFR Part 43 or the applicable airworthiness requirements.The TC240 is designed to operate at full rated load (per Figure 4.1) throughout the specified environmental temperature range (per section 5.2). Note that when operating at full power, the unit case can be hot to the touch. Reference the following examples of selected conditions when operating at maximum rated load of 240 watts (stabilized after 20 minutes):∙At an ambient test temperature of +23°C when not mounted to a metal surface, the maximum case temperature can reach +62°C. (+42°C when mounted to a metal surface) ∙At an ambient test temperature of +70°C when not mounted to a metal surface, the maximum case temperature can reach +87°C. (+68°C when mounted to a metal surface)Caution and consideration should be taken with respect to aircraft installation and operation.SECTION 3 INSTALLATION PROCEDURESINFORMATION3.1 GENERALThis section contains interconnect diagrams, mounting dimensions and other information pertaining to the installation of the TC240 DC/DC Converter.

In order to prevent accidental damage to other systems, it is best not to attach the output to other equipment or power busses prior to verification. Verify the output of the unit at the terminating end of the cable with a multi-meter to ensure proper voltage and polarity. Once verified, installation can be completed and functionality of the remote on/off feature (if used) should be checked.SECTION 4 OPERATION4.1 ELECTRICAL PERFORMANCEThe TC240 is designed as a non-isolated, buck topology, solid-state switch-mode power supply. The unitconverts a direct current voltage (VDC) input to a regulated 5-18 VDC output. It is capable of providing upto 240 watts of power to a variety of aircraft accessories including lights and onboard systems or portableconsumer product power. Rated output current, and thus power, is a function of the user-selected outputvoltage. See Figure 4.1 for maximum current vs. voltage.Figure 4.1TC240 Output Current Performance1012141618202224262857911131517O u t p u t C u r r e n t (A )Output Voltage (V)TC240 Output Current PerformanceMaximumContinuousFEATURES4.2 PROTECTIVE4.2.1 Remote On/OffThe TC240 DC/DC Converter (6430240-2 only) incorporates a remote on/off feature thatallows the user to enable or disable the output of the unit. By providing a ground on theappropriate pin, the user can enable the output of the unit via a remote mounted switch. (SeeFigure 3.4)4.2.2 Input Voltage LimitIf the input voltage exceeds the over-voltage threshold (34VDC), the output will be disabled.4.2.3 Over-TemperatureThe TC240 DC/DC Converter incorporates an internal temperature sensing device thatcontinually provides monitoring and feedback to the control circuits. When the unit senses aninternal condition that exceeds maximum temperature ratings, the output is disabled. TheConverter will continue to remain shut-down until the temperature returns to within acceptablelimits. This over-temperature reset occurs automatically without external interventionrequired.4.2.4 Short Circuit And Over-CurrentThe TC240 DC/DC Converter is capable of surviving a short circuit or over-current eventwithout permanent damage or effect to long-term reliability. The unit can provide over itsrated power output up to 277 watts for over 120 minutes (until over-temperature shutdownoccurs).The Converter monitors the DC output on a pulse-by-pulse scenario to determine a short -circuit or over-current situation. If detected, the output is limited by limiting the current outputto less than 20A. If the short-circuit or over-current situation is removed, the unit will return tonormal operation.SECTION 5 CONFORMANCE 5.1 INSTRUCTIONS FOR CONTINUED AIRWORTHINESSNo periodic scheduled maintenance or calibration is necessary for continued airworthiness of theTC240 DC/DC Converter. If the unit fails to perform to specifications, the unit must be removed andserviced by Mid-Continent Instruments and Avionics or their authorized designee.5.2 ENVIRONMENTAL QUALIFICATION STATEMENTPART NUMBER : 6430240MODEL NUMBER : TC240 NOMENCLATURE : DC/DC ConverterTSO NUMBER : C71MANUFACTURERS SPECIFICATIONS: Test Specification (TS) 688-P, Test Data Sheet (TDS) 688-PQUALIFICATION STANDARD : RTCA DO-160G, dated December 8, 2010CONDITIONS SECTION DESCRIPTION OF TESTTemperature and Altitude Low Temperature High Temperature Altitude Decompression Overpressure 4 4.5.2 4.5.4 4.6.1 4.6.2 4.6.3 Category F1 & F2Operating Low Temp = -40COperating High Temp = +70CAltitude = +55,000 ft.+8,000 to +55,000 ft.-15,000 ft.Temperature Variation 5 Category S2Humidity 6 Category B Operational Shock and Crash Safety7 Category B Vibration 8 Category R; Curve C, C1 [(RCC1)] Category U, Curve G [UG]Explosion 9 Category X Waterproofness 10 Category XFluids 11 Category X Sand and Dust 12 Category XFungus 13 Category F Salt Spray 14 Category XMagnetic Effect 15 Category ZPower Input 16 Category B(XX)Voltage Spike 17 Category BAudio Frequency Conducted Susceptibility18 Category R Induced Signal Susceptibility 19 Category XRadio Frequency Susceptibility 20 Category XEmission of Radio Freq Energy 21 Category MLightning Induced Transient Susceptibility22 Category X Lightning Direct Effects 23 Category XIcing 24 Category X ESD 25 Category A Flammability 26 Category X。

2.机组显示屏必须通电24小时或压缩机油槽温度不低于40℃。

3.检查机组的排气截止阀，吸气截止阀，供液截止阀，喷液截止阀是否打开：4.点击“主画面”，点击“启动”按钮，运行（绿色）指示灯亮，机组倒计时完毕机组按顺序启动。

5.机组启动后听压缩机有无发出异常噪音。

6.当排气压力1．4Mpa或冷凝器进水温度28℃时，启动冷却塔风扇。

7.观察蒸发器出水温度显示是否正常。

z日常停机1.在显示屏的“主画面”点击“停止”按钮，运行指示灯灭，机组慢慢减载直至停机。

2.停止冷凝水水泵与冷却塔风扇。

3.待蒸发器出水温度≤15℃后停止冷冻水水泵。

z长期停机如长时间停机需断开主电源，当环境温度≥5℃时，必须将蒸发器与冷凝器内的水放干净，避免冻坏机组。

麦克维尔单螺杆冷水机组触摸式显示屏操作简介麦克维尔单螺杆冷水机组是单色触摸式显示屏，具有中文显示、显示亮度可调等功能使用方便、操作简单。

在使用时注意表面清洁，勿用硬物将表面划伤。

z触摸式显示屏的操作1、触摸式显示屏上电后，显示屏将显示系统（英文）菜单：A、（Download）下载程序B、（Uploap）上载程序C、（Copy）拷贝程序D、（Contrast）亮度调节E、（Run）进入运行画面2、点击“Run”将显示麦克维尔单螺杆冷水机组主画面，点击“主画面”后显示：设定温度、出水温度、总能量、等待时间，在屏幕下方有三个按键分别为：启动、停止、菜单。

建议的水冷油冷却器接管机房空间与通风机房沿机组长度方向的长度原则上应大于机组总长的 2 倍加 1 米，其余留出空间尺寸也应大于 1 米为宜。

现今市场上的离心式冷水机组电机有开启式和封闭式两种。

封闭式电机由制冷剂冷却，而开启式电机由流过其外表面的空气冷却，其热量还是排在机房里。

麦克维尔离心式冷水机组采用封闭电机，无须另加通风设备。

对于电机采用风冷的机组，由于电机的热量都散发在室内，引起机房室内温度过高，因而在很多场合下都要采用大换气量通风设备或机械冷却设备，以消除机房热量。

运行模式，第一就是常规空调运行，其冷冻水出水温度从 40℉~45℉(4.4℃~7.2℃。

第二种运行模式即为制冰模式，其乙二醇水溶液出水温度从 22℉~26℉(-5.6℃~-3.3℃. MicroTech II 控制系统允许以上两种操作方式。

通过开放协议模板（OPM）或冷冻水温重置信号给微处理器一个数字输入信号，可以使机组开始或停止制冰运行模式。

当收到从蓄冰模式转换成正常运行模式的信号时，冷水机组将停机，直到水温上升到设定值时，机组重新启动，并在更高的出水温度值下继续运行。

当作正常运行模式切换到制冰模式时，冷水机组将加大制冷量，直到水温降到设定值。

电脑选型必须确保机组能在两种工况下运行。

如果“制冰当评估不同的冷水机组时，必须把通风或机械冷却设备的能耗和安装成本考虑进去。

而且，开启式电机冷水机组还增加了这些设备的购买、安装和维修成本。

对采用不同制冷剂的冷水机组机房的通风及安全要求是一个复杂的课题，而且随着时代进步也不断发生变化，具体可参见最近编辑的 ASHRAE15。

模式”是在晚上，则冷凝器和蒸发器之间的压差与正常运行时相差不大。

因为虽然出水温度更低，但晚上冷却塔水温的降低同样会使冷凝温度下降。

如果机组在冷却塔水温较高的白天运行，则要进行正确选择就变得比较困难，因为冷凝器和蒸发器压差很大。

三通冷却水调节阀通常是要求安装于蓄冰系统中。
