YG105 (1/5)2.系统设计的注意点2-1.旋转式压缩机的基本结构2-2.压缩机设计压力（内部高压）压缩机内部压力设计值为(28kg/cm2G)，所以设备高压侧压力一定不能大于(28kg/cm2G)。

2-3.热交换器能力(1)热交换器的能力和空气流量一定要符合运行标准的高低侧压力要求。

(2)与往复式相比，旋转式压缩机具有输入电流对蒸发温度影响不大的特点，因此最好在设计时把蒸发温度定在高的一面。

(3)由于在低的冷凝温度下使用压缩机能有效地减小输入电流，从而减小了击穿电压，增大了冷量。

所以在设计系统时应尽量降低冷凝温度。

(4)总之，如果想要设计一个高效的系统最好按照以上特性(2)和(3)来设计，并且为了使压缩机输出功率低，将蒸发温度定在高的一边，冷凝温度定在低的一边。

2-4.制冷剂充注量尽可能减少制冷剂充注量以防止损害摩擦部件，减少制冷剂充注量不仅能够增强压缩的可靠性，而且能够改善压缩机起动和停机性能。

2-5.制冷量的确定由于它的特性，当在50/60Hz电源频率下运转时，旋转式压缩机比传统的往复式压缩机具有更低的排量。

因此,不仅要考虑在60Hz时制冷剂充注量和压缩机的性能测试，而且要考虑在50Hz时制冷剂充注量和压缩机的性能测试。

YG105 (2/5)2-6.配管与往复式压缩机不同，旋转式压缩机的机芯部分和马达都是固定在压缩机的壳体上，因此压缩机的固定件必须配有抗振橡胶垫块和弹簧来减小压缩机起动和停机时的振动。

所以，在设计和选定连接压缩机的配管时要注意以下几点：(a) 配管和压缩机及其他部件之间的间隙。

(b) 压缩机工作时配管的振动。

(c) 压缩机起动和停机时配管的应力。

(d) 产品运输时配管受到的应力。

在振动很强烈或接触压力上升时，有时最好把产品用橡胶垫块固定。

参照第一部分的有关配管间隙，配管振动和应力的第13，第14，和第15点，在设计中一定不能存在引起配管异常振动和损坏的隐患。

2-7. 电气部品正确使用选配的电气部品。

以下是旋转式压缩机使用的电气部件，每一个的具体规格在压缩机的个别按规定的固定方向固定。

继电器倾斜度不超过5。

压缩机和马达过载保护器之间的的连接线，请使用耐热电线。

（例）四氟化乙烯，六氟化丙烯树脂电线2-8.冷冻机油为了获得高度的可靠性，使用为旋转式压缩机特制的冷冻机油。

这种冷冻机油具有优秀的耐磨性和热稳定性。

其他类型的机油都严禁使用。

2-9.冷冻机油的用量作为起动时等的过渡现象，压缩机的冷冻机油有向系统内大量排出的可能，因此冷冻循环的配管设计要确保回油。

当冷冻循环内装有辅助储液器时，由于容易残留油，必须要考虑回油构造。

另外必须注意开停循环时间较短的场合。

当超过规定的用量和/或发生液体回流时，必须使用尺寸适合的储液器和/或曲轴箱加热器。

2-10.运输时防止振动设计时必须考虑到制冷装置运输时，振动和冲击造成固定件和连接件损坏的情况YG105 (3/5)3. 装置装配上的注意事项在制冷装置上装配旋转式压缩机时，请注意下列项目3-1. 橡胶塞的拔除压缩机的橡胶塞必须从高压侧（排气管及工艺管）拔除。

因为压缩机的内部充有～～cm2G) 的干燥空气，从低压侧（吸气管）拔除橡胶塞时，会有油吹出来。

3-2. 焊接方法在压缩机与配管，配管与配管之间的焊接过程中，请注意绝对不能在冷媒回路中混入焊剂、灰尘、异物、水分等。

3-3. 制冷剂充注方法压缩机已加油，检查“加油”标记。

系统抽真空时，请从高压侧、低压侧同时进行。

（不得不从一侧抽真空时，必须从高压侧抽足够的时间，并确认达到规定的真空度。

）冷媒充注时，必须从制冷装置的高压侧（冷凝器侧）注入。

3-4. 制冷剂充注后的装置运转在制冷剂充注后15分钟内，至少运转1分钟，向压缩机各摩擦部分供给冷冻机油。

3-5. 压缩机的固定压缩机的固定，用规定的避振脚，按规定的固定方法固定，倾斜请控制在5°以内，并按规定安装电器品。

3-6. 起动方法(1)正确接线然后起动压缩机。

接线错误会造成压缩机马达烧毁等严重后果，所以请务必正确接线，并严格检查。

(2)电源关闭到再起动的时间为高低压平衡的时间（大约3分钟），平衡起动。

3-7. 气体泄漏减少旋转式压缩机工作异常率的最好方法是减小装置的气体泄漏，特别是，请注意旋转式压缩机的壳体容量和充注的冷冻机油量都较小，因此在冷冻机油随气体泄漏后，其存油量就不够了，这将会引起润滑不足从而导致摩擦部件的异常磨损。

如果可能的话，进行高压气密性试验，并检查配管的共振和噪声。

3-8. 水分保持冷媒中的水分含量在100ppm以内。

（在60℃(140ºF)）3-9. 抽真空真空度必须抽到133Pa(abs) 为止。

YG105 (5/5)THE GENERAL SPECIFICATIONSFOR SD SERIES ROTARY COMPRESSORIf a compressor is not operated properly, not only will it be impossible to display its performance to the full, but it may lead to a shortened service life and even malfunctions and breakdowns. These operating instructions have been prepared so that the rotary compressor will be used properly and efficiently without malfunctions and breakdowns, and here lists the operation standards and handling precautions. It is recommended that you acquire a full understanding of the special properties of the compressor and that you operate it properly.1. Operation standards and operational limitsWhen the compressor is being used, check with the final test data of the application product to see whether or not the following standards are being maintained.SHEC-EG011 (1/6)2. Precautions for system design2-1. Basic structure of rotary compressorThe rotary compressor is fundamentally different from the reciprocating type in the following ways. Care must beSHEC-EG011 (2/6)2-2. Compressor’s design pressure (high pressure side)The applicable value for the compressor’s design pressure is (28kg/cm2G) and so an equipment design must be selected where the high pressure side design pressure is not more than (28kg/cm2G) .2-3. Heat exchanger capacity(1) The capacity and air flow of the heat exchanger must be determined so that they are compatible with the high and low pressure side pressure of the operational standards.(2) Compared with the reciprocating type, the rotary compressor is characterized by the fact that its input current does not affect the evaporation temperature much. It is therefore a god idea to design the equipment with the evaporation temperature on the high side.(3) Since using the compressor with a reduced condensation temperature is effective in that the input current is reduced, the break-down voltage is reduced and the cooling capacity is increased, every effort should be made to reduce the condensation temperature in the equipment design.(4) Therefore, when aiming for a equipment design with a high it is recommended that the most be made of above features (2) and (3), and the evaporation temperature be set on the high side while the condensation temperature be set on the low side for compressors with a small output.2-4. Amount of refrigerant chargedReduce the amount of refrigerant charged as possible in order to prevent the liquid refrigerant from damaging the sliding parts. Reducing the amount not only increases the reliability of the compressor but also engances the start-up and shut-down characteristics of the compressor.2-5. Capacity settingBecause of its characteristics, the rotary compressor tends to have a lower capacity ratio than the conventional reciprocating type when operated on a 50 / 60 Hz power line frequency. As a result, consideration in the determination of the amount of refrigerant in the equipment and in the performance test should be given to the compre ssor’s performance not only on a 60Hz line frequency but also 50Hz frequency.2-6. PipingUnlike the reciprocating type of compressor, the rotary compressor has a construction where the compression sections and motor sections are fixed to the compressor c ontainer, and so the compressor’s mounting parts employ anti-vibration rubbers and springs to reduce the shock sustained at ON/OFF.Therefore, the following points must be borne in mind when designing the pipes which are to be connected to the compressor and when determining those pipes.(a) Clearance between piping and compressor, and other parts.(b) Piping vibration with compressor operation.(C) Pipe stress with compressor ON/OFF.(D) Pipe stress during product transportation.It is sometimes a good idea to anchor the equipment with rubber packing when vibration may be violent and when contact may arise. Refer to point (14), (15), and (16) in section 1 when it comes to the piping clearance, piping vibration and stress since a design must be implemented where there is no chance of abnormal pipe vibration or damage.SHEC-EG011 (3/6)2-7. Electrical partsUse the designated electrical parts properly. The following electrical parts are used in a rotary compressor and the specifications of each are given in the individual specification sheet of the compressor.Use heat-resistant cable for the leads which are connected to the compressor terminal, motor protectors (attached to compressor).(Example) Ethylene tetrafluoride or polypropylene heaxafluoride resin cable.2-8. Refrigeration oilIn order to maintain a high reliability , one specially developed refrigeration oil for rotary compressors is used. This oil has excellent load-withstanding and heat stability properties. No other type of oil must therefore be used.2-9. Amount of refrigeration oilIt is important for the piping to be designed with sufficient consideration given to oil return during the refrigeration cycle since the refrigeration oil in the compressor is sometimes discharged in volume inside the equipment as a transitional phenomenon (due to the storing of the refrigerant ) during start-up, etc.Oil is liable to collect when an auxiliary accumulator is attached within the refrigerating cycle, which necessitates an oil-return structure. Care is required with short ON/OFF cycles. In the event of exceeding the restricted amount and / or liquid flood back, it is mandatory that a properly sized accumulator and / or crankcase heater be used.2-10. Immunity from vibration during transportationSufficient consideration in design must be given so that mounting parts and connected parts are not damaged as a result of vibration or shock sustained while transporting the fully assembled equipment.SHEC-EG011 (4/6)3. Precautions with equipment assembly.The following points must be borne in mind when incorporating the rotary compressor into the application product.3-1. Removal of rubber plugsThe rubber plugs must be removed from the high pressure side ( and process pipe ). Compressors are charged dry-air at the pressure of ~ ~1.0kg/cm2G). If the rubber plugs are removed from the lower pressure side (suction pipe),it is feared that oil in the compressor is gushed out.3-2. Welding methodTake care not to allow flux, dirt, foreign matter or moisture to enter the refrigeration circuit while weldingbetween pipes or welding the pipes to the compressor.3-3. Refrigerant charging methodThe compressor is supplied with oil.Create the vacuum from both the high and low pressure side. ( If it is possible to the create the vacuum from one side only, take sufficient time at the high pressure side and check that the prescribed vacuum gas has been created.) Always charge the refrigerant from the high pressure side ( condenser ) of the unit.3-4. Equipment operation after refrigerant chargeWithin 15 minutes after having charged the refrigerant, operate for at least 1 minute and supply refrigeration oil to the sliding parts of the compressor.3-5. Parts securingSecure the compressor properly with the prescribed method and using the prescribed anti-vibration rubber pieces. The secured compressor must lean less than 5°from the perpendicular. Mount the electrical parts properly as instructed in section.3-6. Starting method(1) Connect the proper circuits and then start up the compressor.(2) Make the time span from power OFF to re-start the same as the time taken for the high and low pressure to bebalanced ( about 3min ), then balanced starting.3-7. Gas LeaksThe best way to reduce the failure rate among rotary compressors on the market is to reduce the equipment gas leaks. In particular, it should be remembered that rotary compressors have a small volume inside the case and a small amount of charged refrigeration oil, when they are operated with gas leaking, the absolute amount of refrigeration oil will be insufficient and this will cause abnormal wear of the sliding parts due to insufficient lubrication.When possible, carry out an air-tightness test with the high pressure increased and check for pipe resonance and buzzing noises.3-8. MoistureKeep the amount of balanced moisture inside the refrigeration circuit ( including compressor ) within 100ppm [at 60℃（140°F）].Moisture level in the refrigeration system should be maintained as low as possible.SHEC-EG011 (5/6)3-9. EvacuationA degree of vacuum about 133Pa[abs] is desirable.3-10. Contaminants / foreign obstacles(1) Carefully avoid the fluxes, contaminants ( such as metal or fiber scraps ) to mingle inside the compressors.(2) Install a strainer ( with about 50 mesh ) within the refrigeration circuit and avoid the clogging of capillary tube,etc..3-11. General handling precautions(1) The compressor should be installed in the refrigeration system within 1 year from the manufactured date.(2) The compressor should not be left for more than 30 minutes unsealed.(3) Do not carry out compressor self-actuated vacuum condition.(4) Never operate the compressor as an air compressor.(5) Never supply electricity under the vacuum condition.(6) Do not severely tilt the compressor, drop it or cause it to topple over while transporting.(7) Do not scratch the painted surfaces.4. Quality of compressor4-1. Insulation(1) Insulation resistanceInsulation resistance should be more than 10M between each of the terminals and the ground ( or the shell ), and between each of the terminals with a megger.(2) Dielectric withstandA 50 or 60Hz potential as indicated below should be applied between live parts and dead metal parts.1000v for 1 minute, or 1200v for 1 second ( Nominal 100~120v )1500v for 1 minute, or 1800v for 1 second ( Nominal 200~240v )2000v for 1 minute, or 2400v for 1 second ( Nominal 346~480v )4-2. Air-tightness and Strength Test(1) Air-tightness test pressure : (28kg/cm2G)(2) Hydrostatic strength test pressure : (84kg/cm2G)4-3. DrynessThe inside of compressor is dried up. The remaining quantity of moisture measured by MELCO procedure should be below 120mg.4-4. CleannessThe inside of compressor is cleaned, there should be no dust or any harmful matter.4-5. Endurance in transportationThe compressors is proof against vibration and shock in normal transportation.SHEC-EG011 (6/6)。
