This product has advantagesof stable system, low oscillation, high reliability and high effectiveness on energy saving. MENERGY original anti-reversal program for the compressor can strengthen the running reliability of the chiller. This product has more than twenty types for being extensively applied in many comfortable or technical situations by the customer.Before the chiller is started up, all the related personnel in charge of setup, startup, operation and maintenance should carefully read through this manual so as to know all the precautions onsite.Schematic drawing for service clearance Sin gle-head:Dual-head:____________ r————Schematic drawing for hoisting Sin gle-head:Dual-head:Attention: Use protecting barwhe n hoist ingSetup and maintenanceSetup and maintenance of the chiller should only be carried out by a qualified person whohas bee n trained professi on ally, and is familiar with local sta ndards and rules and haspractical operational experienee. The trial running of the chiller must be carried out by theprofessional service supplier to ensure the quality of the chiller.Check before acceptanceAfter the device has arrived, check if all the items listed in the delivery order arecomplete, and any part damaged duri ng tran sportati on should be in formed to the forwardi ngage nt with writte n form for claim. Before setup, check if the local supply voltage, frequencyand so on are complying with the chiller. MENERGY will bear no liability for any damage afterthe device has bee n accepted.HoistingHeavy-duty ropes or chains should be used for hoisting through the hoisting holes of thechiller, and the con trol cab in et a nd other parts of the chiller should be protected fromdamage whe n hoisti ng (The schematic draw ing for hoist ing in troduced above should bereferred to).Environmental requirementThe chiller is suitable to be used in the en vir onment that the surro unding temperatureis -15 °C above and the relative humidity is<95%, and the ground for placeme nt should be horiz on tal and with eno ugh solidity or rein forceme nt measures should be take n (The requirementsin the schematic drawings of ground base and service clearanee for the chiller should bereferred to).Water quality requirementAs the compositi on of local water is complicated, the water quality should be check whe nsome un com mon water (such as in dustrial waste water, ground water, etc.) is used. If thewater quality does not satisfy the requirement for the water used in air-conditioning, the watershould be treated accordi ng to the Specificati on for Desig n of In dustrial Re-circulat ingCooli ng Water Treatme nt or other related sta ndards.c「mg/L v 200 v 200SO42-mg/L v 200 v 200SiO2 mg/L v 50 v 50NH4 +mg/L v 1.0 v 1.0S2-mg/L Not allowed Not allowedFree Chlori ne mg/L v 1.0 v 1.0Oil mg/L v 5 v 5Water pipesBoth outlet and inlet of the chiller should be equipped with a stop valve, a thermometer and a pressure gauge for routi ne check and maintenance of the water system; and both outlet and inlet of the water pump should be equipped with a stra iner to preve nt impurities from going into the pump or the vessel; before insulating the heat of the water pipe, the seali ng of the pipeli ne should be checked whe n the water is to go into the chiller; all the pipeli nes conn ected with the chiller should be equipped with vibratio n dampers and flow con trollers (such as water flow valves, water pressure differe nee switch, etc.) as per the requirement; when a device for contamination draining is to be mounted to the water system of the air-conditioning engineering, it should be avoided from the pipelines of the outlet and inlet of the chiller, or the normal operation of the chiller would be disturbed.

Check before starting upWater circuit partCheck all the pipelines of the water system to ensure that the evaporator and the condenser are correctly connected and the water flow direction is correct. Check if the inlet pipe and the outlet pipe of the heat exchanger mentioned above are well connected, and then open all the water valves and start up the corresponded water pump to wash the pipes so as to ensure the water system is clean and check if there is any leakage at the pipes and joints. Discharge the air in the water circuit of the evaporator and the condenser, and the water circuit should be keep clean away from rust. Check the resistance loss at the water side of the evaporator and the condenseragainst the water volume. Check if the temperature transducers are correctly connected. Electric circuit partCut off the main isolating switch and then check all the startup circuits and control circuits of the control cabinet to ensure all the switches are in off position. Check the power supply to the chiller and the voltage fluctuation range should be within 10% of the±rated voltage shown on the nameplate of the compressor, and the unbalance of the phase voltage should be within 2%. Check if there is enough power supply capacity to ensure the startup andfull load running of the chiller. Check if all the electric wires and fuses have the matched specification with the running of the chiller, and finish all the interlock control circuits according to the related electric control drawing. Check and ensure all the ancillary equipments and control equipments for air-conditioning are in normal operation and have enoughrefrigerating capacity to satisfy the running requirement of the chiller at the first operation. Chiller partMake sure that the engine oil heater of the compressor has been electrified for 24 hours, and examine the oil level through the inspecting mirror of the oil separator,and refill oil if the oil level can not be seen. Fully open the manual stop valve on the sparging pipe and remove the seal bonnet away, and fully open the suction and discharge stop valve and then counterclockwise turn it back for 1/2 circle, and then fully open the liquid supply stop valve and start up the ancillary equipments, the condensed water pump and the refrigerated water pump, and finally check if all the safety control equipments are in original status and if thesettings are correct. See <Table 1> below for the related items for checking.Safety equipmentsThe chiller is equipped with safety protective devices to ensure safe running, and if one of the safety protective devices is in operation, an error indicator will turn on, and the corresponded function will stop while the other functions will be still normal. It isrecomme nded to stop the chiller for troubleshoot ing to avoid from more serious accide nt only if any part becomes abnormal. See vTable 2> for the detailed series of the safety protective devices of the chiller.Recommended running rangeRecommended maintenance periodsTroubleshooting for the Screw-type ChillerPart 2 Controlling and handlingSECTION 1 INTRODUCTIONand technician, if act against this rule, FRIMEC will not respond for any unit damage and people injured.Operati ng Con diti onIn stall the equipme nt below 2000 meters altitude.Ambient Temperature: Max. 45C , Min. -20 °C .Relative Humidity: Less than 85%.No con ductive dust and corrosive gas which may destroy metal and in sulati on.Fun cti on Feature of Con trollerSCHNEIDER PLC is the controller for chiller.

麦克维尔WHS单螺杆冷水机组简介
多压缩机设计
保证部分负荷下高效率
• 采用单台压缩机增减载控制方式
• 保证部分负荷下，压缩机处于高负荷状态
减少对电网冲击
• 采用单台压缩机卸载启动
机组的备用性能好
• 80%的制冷季节有压缩机备用
独立的制冷回路
保证机组灵活的维护性能
• 单台压缩机的维护不会影响其他压缩机的运行
• 冷媒、润滑油的更换更加节省 • 各个回路保证污染隔离
双螺杆压缩机
油系统复杂，需采取油回收系统，以避免供液 过大或负荷变化过大时冷冻机油进入换热器， 造成机组效率快速下降和系统运行恶化。 较大冷量的双螺杆机运行时一般需持续起动油 泵，油耗量大，维修投资多。
单螺杆原理
单螺杆压缩机： 一个主动转子与两个星轮啮合旋转时产生周期 性容积变化 压缩机为开启式、半封闭式 齿数比为6:11，星轮转速（约1750RPM）远较双 螺杆低得多
可靠的轴承设计
McQuay 的星轮压缩机
无几何空间限制 无大的轴承负荷 无须大的油平衡活塞来平衡轴向力 PES开启式单螺杆压缩机轴封负荷极 小，故比双螺 杆有更佳的轴封密封 超长的轴承寿命 L10 轴承寿命达 100,000 小时
单螺杆VS双螺杆
单螺杆压缩机 100,000 h 的轴承寿命 维修周期一般为： 40,000h 双螺杆压缩机 40,000 h 的轴承寿命 维修周期一般为： 15,000-20,000h
基本点
单螺杆压缩机为容积型回转式压缩机 兼有往复式压缩机和离心式压缩机之优点 应用于冷冻冷藏、制冰、民用及商用空调、 工业制冷场合 半封闭、全封闭、开启式压缩机型式
历史
双螺杆压缩机 发展于1934年，主要制造商有： Bitzer Carrier Dunham-Bush Hitachi Trane York (Frick)
