科士达机房精密空调工业冷水机组遇断水时怎么办？

科士达机房精密空调工业冷水机组遇断水时怎么办？长期使用工业冷水机什么样的故障都能够遇到。而对于工业冷水机而言，如果出现断水问题非常危险，必须及时有效的进行处理。如果延误最佳的处理时机，将会导致工业冷水机产生严重的故障，甚至导致设备无法正常运行。科士达机房精密空调工业冷水机产生断水故障的原因不同，因此在处理故障的时候，第一步需要分析出导致断水的具体原因。

日常使用工业冷水机的时候，工业冷水机散热全部依靠水源将热气带走，如果在高速运行的时候，突然没有任何水源的流动，那么大量的热量无法及时的进行挥发，导致温度上升的速度非常快。当温度达到高温临界点的时候，工业冷水机会通过停机的方式保护自己。因此断水故障只要出现，工业冷水机通常会在运行15分钟左右的时候停止运行，以达到保护工业冷水机核心部件的目的。

What happens when the water is cut off for the industrial water chiller of the Precision Air Conditioning System in the Costa Machine Room? Long-term use of industrial water chillers can encounter any kind of failure. For industrial water chillers, if the water cut-off problem is very dangerous, it must be dealt with in time and effectively. If the best treatment time is delayed, serious faults will occur in industrial water chillers, and even the equipment will not work properly. The reasons for water cut-off of industrial water chillers in the precision air-conditioning system of Kosta engine room are different, so the first step is to analyze the specific reasons for water cut-off.
In the daily use of industrial water chillers, the heat dissipation of industrial water chillers relies entirely on the water source to take away the hot air. If there is no water source flowing suddenly at high speed, then a large amount of heat can not be volatilized in time, resulting in a very rapid rise in temperature. When the temperature reaches the critical point of high temperature, the industrial cold water opportunity protects itself by shutting down. Therefore, as long as the water breakdown occurs, the industrial water chiller usually stops running for about 15 minutes in order to protect the core components of the industrial water chiller.

科士达机房精密空调遇到断水的故障怎么处理？

1、区分断水的具体原因

工业冷水机产生断水故障的原因不同，因此在处理故障的时候，第一步需要分析出导致断水的具体原因。如果由于水源出现问题，仅仅需要及时恢复水源的供应即可恢复工业冷水机的运行。如果属于水泵类的故障，此时需要针对设备进行全面的维护与保养，及时排除水泵的故障，同时进行全面的测试。确保水泵恢复正常工作，才能够正常开启工业冷水机。

2、科士达机房精密空调立刻停机维修 直到水流量恢复正常

在维修工业冷水机的时候必须停机进行操作。由于运行中的工业冷水机会产生更多的热量，在运行十分钟左右同样会停机。因此在停机的状态下进行维修检测，能够避免产生额外的高温，主要能够确保工业冷水机处于正常的运行温度范围内，即可保障工业冷水机处于正常的运行状态。

遇到各种科士达机房精密空调工业冷水机的故障不需要过度慌张。利用专业的设备针对工业冷水机进行认真仔细的分析，能够找出导致故障的根本原因。然后根据自己的具体能力，制定适合的维修计划，在最短的时间内，保障工业冷水机重新运行。

科士达机房精密空调工业冷水机的保护装置有哪些？科士达机房精密空调工业冷水机是一种水冷却设备，是能够提供恒温、恒流、恒压的冷却设备。冷水机的原理是想将一定量的水注入机器的内部水箱，通过冷水机制冷系统将水冷却，而后有机器内部的水泵将低温冷冻的水注入需要冷却的设备内，冷冻水将机器内部的热量带走，将高温的热水再次回流到水箱进行降温，如此循环交换冷却，达到为设备冷却的作用。

How to deal with the problem of water cut-off in the precision air-conditioning system of Costa engine room?
1. Distinguishing the Reasons for Water Separation
The causes of water cut-off of industrial water chillers are different, so when dealing with the failure, the first step is to analyze the specific causes of water cut-off. If there is a problem with the water source, the operation of industrial water chillers can be restored only by restoring the water supply in time. If it belongs to the fault of water pump, it is necessary to carry out comprehensive maintenance and maintenance for the equipment at this time, eliminate the fault of water pump in time, and conduct comprehensive testing at the same time. Only by ensuring that the pump returns to normal operation can the industrial water chiller be opened normally.
2. The Precision Air Conditioner in the Costa Machine Room will be shut down and maintained immediately until the water flow returns to normal.
When repairing industrial water chillers, the machine must be shut down for operation. Because the industrial cold water in operation generates more heat, it will also shut down in about ten minutes. Therefore, the maintenance and inspection under the condition of shutdown can avoid the extra high temperature, mainly to ensure that the industrial water chiller is in the normal operating temperature range, which can ensure the normal operation of the industrial water chiller.
There is no need to panic excessively when encountering all kinds of faults of industrial chillers of precision air conditioning in Kosta engine room. Careful and careful analysis of industrial water chillers with professional equipment can find out the root causes of the failure. Then, according to their specific capabilities, make appropriate maintenance plans, in the shortest possible time, to ensure the re-operation of industrial water chillers.
What are the protective devices for the industrial water chiller of the precision air conditioning in the Costa engine room? The industrial water chiller for precision air conditioning in Kosta Machine Room is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of water chiller is to inject a certain amount of water into the internal water tank of the machine, and cool the water through the cooling system of the water chiller. Then the water pump inside the machine injects the cryogenic frozen water into the equipment that needs cooling. The chilled water takes away the heat inside the machine and returns the high temperature hot water to the water tank for cooling, so as to circulate and exchange cooling, so as to achieve cooling for the equipment. Use.

科士达机房精密空调工业冷水机在工作的过程中，为了保证正常工作，冷水机都会有保护装置，一般的保护装置有吸排气压力保护，油压差保护，冷却水套断流保护等措施，这些保护措施具体是怎么工作的呢？下面请看具体的分析。

1、吸排气压力保护：主要是防止压缩机吸气压力过低和排气压力过高。用压力控制器，吸气压力和排气压力达到警戒压力值时，另压缩机停止运转。

2、科士达机房精密空调油压差保护：用于有油泵供油的压缩机，防止油泵不上油影响压缩机润滑及造成气缸卸载机构不能正常工作。保护的方法是用油压差控制器检测油泵进出口油压差，若油压差持续60g左右达不到正常值(0.15MPa左右)时，则令压缩机停机。

3、压缩机排气温度和油温保护：由于防止排气温度过高和油过低或过高。用温度控制器，当上述温度达到警戒值时，令压缩机停机。

4、科士达机房精密空调冷却水套断流保护：氨压缩机气缸头设有冷却水套对压缩过程施加外冷却。用水流继电器座冷却水断流保护控制，若持续断流达到指定时间，则控制压缩机停机。采用制冷剂液泵向蒸发器强制供液循环的制冷系统中，若泵运转中不上夜，将造成制冷剂液泵的气蚀损坏和烧毁电机。用压差控制器检测泵前后流体压力差，若压差持续8~15s达不到正常值则控制泵停止运行。

科士达机房精密空调制冷系统外部的冷却水系统和冷水系统也要用到冷却水泵和冷水泵，这些水泵运行中会遇到同样的问题，也用压差控制器实施同样的保护性控制。冷水机组制冷系统中的高压容器(如制冷剂在壳侧的水冷式冷凝器，高压贮液器等)，为了避免内压过高时造成壳体破损，在容器上设有安全阀。安全阀在内压超过控制值得10%时自动打开，通过紧急释放其中的高压介质，抑制容器内压升高。

In order to ensure the normal operation of the industrial water cooler in the Precision Air Conditioning Industry of Costa Machine Room, the water cooler will have protective devices. The general protective devices include suction and exhaust pressure protection, oil pressure differential protection, cooling water jacket interruption protection and other measures. How do these protective measures work? See the specific analysis below.
1. Suction and exhaust pressure protection: mainly to prevent compressor suction pressure is too low and exhaust pressure is too high. With the pressure controller, when the suction pressure and exhaust pressure reach the warning pressure value, the compressor will stop running.
2. Precision air-conditioning oil pressure differential protection in Costa engine room: It is used for compressors with oil pumps to supply oil, so as to prevent the lubrication of compressors and the cylinder unloading mechanism from working properly. The method of protection is to detect the oil pressure difference between the inlet and outlet of the oil pump by the oil pressure difference controller. If the oil pressure difference lasts about 60 g and can not reach the normal value (about 0.15 MPa), the compressor will be shut down.
3. Compressor exhaust temperature and oil temperature protection: to prevent excessive exhaust temperature and oil too low or too high. With the temperature controller, when the above temperature reaches the warning value, the compressor shuts down.
4. Cut-off protection of cooling water jacket for precision air-conditioning in Kosta engine room: There is cooling water jacket on the cylinder head of ammonia compressor to apply external cooling to the compression process. Water flow relay seat cooling water cut-off protection control, if the continuous cut-off reaches the specified time, then control the compressor shutdown. In the refrigeration system where refrigerant liquid pump is used to force liquid supply to evaporator, if the pump does not work overnight, it will cause cavitation damage of refrigerant liquid pump and burn motor. The differential pressure controller is used to detect the fluid pressure difference before and after the pump. If the differential pressure lasts for 8 to 15 seconds and does not reach the normal value, the pump is controlled to stop running.
Cooling water pumps and chilled water pumps are also used in the cooling water system and chilled water system outside the precise air conditioning and refrigeration system of the Kosta engine room. These pumps will encounter the same problems in operation, and the same protective control will be implemented by the differential pressure controller. In order to avoid shell damage caused by excessive internal pressure, a safety valve is installed on the high pressure vessel (such as water-cooled condenser with refrigerant on the shell side, high pressure liquid reservoir, etc.) in the refrigeration system of water chiller. The safety valve opens automatically when the internal pressure exceeds 10% of the control value, and restrains the increase of the internal pressure of the container by releasing the high-pressure medium urgently.

尺寸小的高压容器可以使用更简单的易熔塞或安全膜。科士达机房精密空调当容器内温度(压力)超过警戒值时，易熔塞或安全膜破裂，使容器的高压介质排出。制冷系统正常运行时，各管路中制冷剂按一定方向运动，在有可能出现反向运动并造成危害的场合，相应管路上应设单向阀，起自动阻止反向流动的作用。

为什么科士达机房精密空调工业冷水机要定期更换优质的防冻液？在工业冷水机运行的时候对防冻液的使用标准要求较高，普通设备不能够使用浓度较高的防冻液，如果科士达机房精密空调防冻液的浓度较高，在运行设备之前需要消耗的预热时间很长，如果预热效果不好，同样会影响到工业冷水机的正常使用。因此客户在选择更换防冻液的时候，需要结合实际的使用环境与空间的大小，确定更换的工业冷水机产品类型，以便达到预期的使用效果。

客户降低运行工业冷水机的风险，主要方法为提高科士达机房精密空调工业冷水机的降温性能。即便同一款式的工业冷水机，不同的使用方法，对于工业冷水机将会产生不同类型的影响。很多客户在使用工业冷水机的时候，由于缺少基础的保养及时，导致设备的运行效率较低。即便消耗大量能源，同样无法达到预期的使用效率，其实科士达机房精密空调工业冷水机之所以出现能源消耗量较多等等问题，与防冻液的品质出现必然的联系。

通过更换优质的科士达机房精密空调防冻液，能够延长保养防冻液的周期。在一个周期范围内，能够使用的时间越长，客户后期保养支出的费用越低。有效提高客户使用工业冷水机的安全性，避免经常出现各种小故障，而影响到工业冷水机的正常使用。

Small pressure vessels can use simpler fusible plugs or safety membranes. When the temperature (pressure) in the container exceeds the warning value, the fusible plug or safety film breaks down, which causes the high-pressure medium of the container to be discharged. When refrigeration system is in normal operation, refrigerant in each pipeline moves in a certain direction. In the case of possible reverse movement and harm, one-way valves should be installed in the corresponding pipeline to automatically prevent reverse flow.
Why do the precision air-conditioning industrial water chillers in Costa Machine Room need to replace high-quality antifreeze fluid regularly? In the operation of industrial water chillers, the use standard of antifreeze is higher. Normal equipment can not use antifreeze with higher concentration. If the concentration of antifreeze is higher in the precision air-conditioning of Kosta machine room, it will take a long time to warm up before running the equipment. If the preheating effect is not good, it will also affect the normal use of industrial water chillers. Therefore, when choosing to replace the antifreeze, customers need to determine the type of industrial water cooler products to achieve the desired use effect according to the actual use environment and space size.
Customers reduce the risk of running industrial water chillers. The main method is to improve the cooling performance of industrial water chillers for precision air conditioning in Costa's machine room. Even if the same type of industrial water chiller, different use methods will have different effects on the industrial water chiller. Many customers in the use of industrial water chillers, due to the lack of basic maintenance in time, resulting in low efficiency of equipment operation. Even if a large amount of energy is consumed, the expected use efficiency can not be achieved. In fact, the reason why the energy consumption of the water chiller in the precision air-conditioning industry of Costa Computer Room is more is inevitably related to the quality of antifreeze.
By replacing the high-quality anti-freeze liquid of the Precision Air-conditioning in the Costa Machine Room, the maintenance period of the anti-freeze liquid can be prolonged. Within a cycle, the longer the time it can be used, the lower the cost of customer's later maintenance expenditure. Effectively improve the safety of customers using industrial water chillers, avoid all kinds of minor failures, and affect the normal use of industrial water chillers.

目前市场上有许多科士达机房精密空调冷水机组都是依照以下思路构造：冷冻油与制冷剂混合，利用油别离器将机组冷冻油与制冷剂别离，再使制冷剂通过满液式蒸发器回到压缩机。这种机型制冷作用好，推广度较大，可是其运转中存在一个疑问，那即是容易“跑油”，即当冷却水温偏低时，排气过热度不高，然后油与制冷剂别离不完全，混合物进入热交换器后致使机组低压偏低，更有甚者会致使膨胀阀阻塞形成机组无法启动。

1、油别离器里边看不到任何油的踪迹，此刻油并没有在冷凝器内聚集，而是通过了膨胀阀进入到蒸发器内，油会粘到蒸发器换热铜管上面，使蒸发器的蒸发作用欠好，形成蒸发器内压力偏低，一起使压缩机的吸气过热度很低乃至直接将制冷剂液体吸入，和时压缩机排温很低，油与制冷剂仍然无法别离，如此的恶性循环会使一切的油都聚集在蒸发器内，压缩机由于供油缺乏宣布无穷噪音，乃至机组油别离器油位报警而停机。

2、油别离器里边看不到任何油的踪迹，一切的油都跟着排气来到了冷凝器内，假如水温继续偏低，那一切的油都会聚集到冷凝器内，并使膨胀阀发作油堵，蒸发器内由于供液量缺乏，压力开端降低，一直到低压报警停机。

以上即是所谓的跑油现象。其主要原因即是由于冷冻水温度偏低，排气温度低。

在科士达机房精密空调开机过程中遇到此类疑问的解决方法如下：

1、当发现油分内油位在降低时，马大将机组调到手动操控形式，约束压缩机负荷，例如将其能量约束在50%上。

2、将冷水机组的低压报警值和低压停机值降低到允许范围内，尽量保证机组能处于运转状况。

3、假如此刻油位仍然很低，并且蒸腾器内压力也很低的话，就要考虑到是不是油都跑到蒸腾器内了。从蒸腾器视液镜内看看是不是有很多白色泡沫在翻滚，假如有，阐明油都在蒸腾器内，反之则有可能在冷凝器内。

4、有了以上几个过程，科士达机房精密空调通过半个小时摆布，冷却水的温度和排气温度应当会增加至正常，下面开端收油：油在蒸发器内。此刻密切留意冷冻水的温度，能够先恰当减小其流量，让出水水温降低，然后敏捷增大流量，使蒸发器出水温度敏捷增加，这时的水温会超越制冷剂的饱满温度许多，然后使制冷剂剧烈欢腾，冷冻油便会跟着翻滚的制冷剂泡沫被吸如压缩机，这时排温应当会降低一些，可是也应当远超越了油与制冷剂的别离温度，然后将油带回油别离器并使它们别离。反复几回，油就会悉数回收到油别离器内。这儿留意每次调理水量的时间距离，最好是每次调理后使排气温度回升到调理前最好。

油在冷凝器内。这时不需要太留意水温，科士达机房精密空调只需机组能正常运转就不会有很大的疑问。此刻应当将膨胀阀逐渐敞开至最大（敞开过程不亦过快，防止供液量太大损伤蒸腾器内铜管），等候几分钟，直到机组高低压平衡，这时能够从蒸腾器的视液镜内看到很多白色泡沫，这即是油现已从冷凝器内进入到了蒸腾器内。只需重复A过程，油就会很快的回收来了。

At present, there are many precision air-conditioning chillers in Kosta engine room in the market according to the following ideas: mixing refrigerant with refrigerant, separating refrigerant from refrigerant by oil separator, and then returning refrigerant to compressor through full-liquid evaporator. The refrigeration effect of this type is good and its popularization is large, but there is a doubt in its operation, that is, it is easy to "run off oil", that is, when the cooling water temperature is low, the exhaust superheat is not high, and then the oil and refrigerant are not completely separated, the mixture into the heat exchanger will cause the low pressure of the unit, or even cause the expansion valve blockage to form the unit can not start.
1. There is no trace of oil in the oil separator. At the moment, oil does not accumulate in the condenser, but enters the evaporator through the expansion valve. Oil will stick to the copper tube of heat exchanger of the evaporator, so that the evaporation of the evaporator is not good and the pressure in the evaporator is low. Together, the superheat absorption of the compressor is very low, and even the refrigerant liquid is directly inhaled, and the compressor The exhaust temperature is very low and the oil and refrigerant are still inseparable. Such a vicious cycle will make all the oil gather in the evaporator. The compressor shuts down because of the lack of oil supply to announce infinite noise, and even the oil level alarm of the unit oil separator.
2. There is no trace of oil in the oil separator. All the oil comes to the condenser with the exhaust gas. If the water temperature continues to be low, all the oil will gather in the condenser, and the expansion valve will be blocked. Because of the lack of liquid supply in the evaporator, the pressure starts to decrease until the low-pressure alarm stops.
The above is the so-called phenomenon of oil running. The main reason is that the temperature of frozen water is low and the exhaust temperature is low.
In the process of startup of the precise air-conditioner in the Kosta engine room, the solutions to these problems are as follows:
1. When it is found that the oil level in the oil is decreasing, Madagascar adjusts the unit to manual operation to restrain the load of the compressor, for example, to restrain its energy at 50%.
2. Reduce the low-pressure alarm value and low-pressure shutdown value of chillers to the allowable range to ensure that the chillers are in operation as far as possible.
3. If the oil level is still very low at the moment and the pressure in the transpirator is also very low, we should consider whether the oil has run into the transpirator. From the perspective of the transpiration mirror, see if there are many white bubbles rolling. If there is, the oil is in the transpiration device, otherwise it may be in the condenser.
4. With the above several processes, the precision air-conditioning system in the Kosta engine room can be operated for half an hour. The temperature of cooling water and exhaust gas should be increased to normal. The oil should be collected in the evaporator. At the moment, pay close attention to the temperature of chilled water, which can first reduce the flow of the water properly, reduce the temperature of the outlet water, and then rapidly increase the flow rate, so that the temperature of the evaporator outlet water will increase rapidly. At this time, the water temperature will exceed the full temperature of the refrigerant, so that the refrigerant will be jubilant, and the cold oil will be sucked like the refrigerant froth like the compressor, so the temperature should be reduced. Some, however, should also go far beyond the separation temperature of oil and refrigerant, and then bring the oil back to the oil separator and make them separate. Repeated several times, the oil will be fully recovered into the oil separator. Here pay attention to the time distance of each conditioning water volume, it is best to make the exhaust temperature rise back to before conditioning after each conditioning.
Oil is in the condenser. At this time, there is no need to pay too much attention to the water temperature, and there will be no great doubt that the precise air-conditioning system in the Kosta engine room only needs the normal operation of the unit. At the moment, the expansion valve should be gradually opened to the maximum (the opening process is not too fast, to prevent excessive liquid supply, damage the copper tube in the transpiration device), and wait for a few minutes until the unit has high and low pressure balance. At this time, many white foam can be seen from the liquid lens of the transpirator, that is, the oil has already entered the transpiration device from the condenser. Just repeat process A and the oil will be recovered quickly.

科士达机房精密空调冷冻机跳闸怎么办？冷冻机起动时跳闸是很多用户在初次使用冷冻机时有可能遇到的问题。国内冷冻机使用的范围较为广泛，虽然国内冷冻机并且具备较高的性能，但是在实际的使用过程中，同样存在出现故障的概率。冷冻机在满足起动条件的情况下，还是发生跳闸的情况，那么首先就要从供电电源来检查，排除电源问题后，再从机组控制系统，以及机组自身，制冷系统使用状况和环境等方面来逐一排查。

What should be tested for the operation stability of industrial chillers for precision air conditioning in Kosta machine room? Different enterprises have different requirements for low temperature environment. Therefore, when choosing industrial chillers, it is necessary to analyze the operation efficiency and stability of industrial chillers and select industrial chillers that are really suitable for enterprises. In order to meet the operation requirements of industrial water chillers and reduce the cost of using industrial water chillers, the operation efficiency of industrial water chillers should be improved.
Different types of industrial water chillers have different overall operation efficiency. If the enterprise chooses the high efficiency industrial water chiller equipment, but the space range is small, then the enterprise uses the industrial water chiller in a wasteful state. The long-term operation of high power not only leads to the increasing cost of using industrial water chillers, but also affects the service life of industrial water chillers. Therefore, in order to maintain the long-term safety and stability of the equipment and reduce the probability of equipment failure, it is necessary to tailor the appropriate industrial water chiller equipment to the actual operating environment.
Criteria for judging the operation stability of industrial water chillers for precision air conditioning in Costa Machine Room
Enterprises want to judge whether the operation efficiency of industrial water chillers is in a safe range, in fact, it is very simple. In the actual operation of industrial water chillers, if the temperature of the environment decreases slowly, even in a small space, industrial water chillers can not quickly complete the establishment of low-temperature environment in a short time, indicating that there are problems in the operation efficiency of industrial water chillers. In order to avoid expanding the scope of the fault and affecting the persistence and stability of the low-temperature environment of enterprises, it is necessary for enterprises to make timely troubleshooting.
If the operation efficiency of the industrial water chiller of the precision air conditioning in the Kosta machine room is low, the enterprise can solve this kind of problem by replacing the industrial water chiller. For the unstable operation caused by equipment failure, it is necessary for enterprises to maintain and maintain industrial water chillers in a timely manner, and to deal with the faults and possible faults of industrial water chillers. Only by ensuring the stable operation of industrial water chillers can the operation safety of industrial water chillers be improved and the normal use of industrial water chillers in enterprises be ensured to complete production tasks.
Enterprises want to maintain the operation stability of the industrial water chillers in the precision air-conditioning industry of Costa Machine Room, need to regularly test the core components. It can ensure the safe and efficient operation of the core components, and has an important impact on improving the operation efficiency of industrial water chillers. It can provide basic guarantee for the safe and efficient use of industrial water chillers in enterprises, and avoid all kinds of failures affecting the normal use of industrial water chillers.
What about the trip of the precision air-conditioning refrigeratory in the Costa engine room? Tripping when the refrigerator starts is a problem that many users may encounter when they first use the refrigerator. Domestic refrigerators are widely used, although domestic refrigerators have high performance, but in the actual use process, there is also a probability of failure. When the refrigeratory meets the starting conditions, or trips occur, it is necessary to check from the power supply first, after eliminating the power supply problems, and then from the unit control system, as well as the unit itself, refrigeration system usage and environment to check one by one.

科士达机房精密空调冷冻机起动时跳闸是很多用户在初次使用冷冻机时有可能遇到的问题。国内冷冻机使电源故障的原因有很多，主要还是表现在以下三点：

第一、供电系统的三相电源缺相。冷冻机常用的电源是3相、380V、50HZ，如果是供电线路损坏，或者是开关和电缆结合处松开，以及开关本身的接触故障，都会导致缺相，尤其是开关本身的故障是比较常见的，这类故障时可以用万用表查出来的。

第二、科士达机房精密空调供电系统开关的参数设置不符合要求，在排除掉开关的质量问题后，冷冻机启动还是会跳闸，那我们就要查看参数设置。如果开关允许的工作电流小于起动电流，那肯定会出现启动跳闸现象;如果短延时电流参数设置过低，冷冻机有低速转高速时受到冲击电流影响也会跳闸。因此在检修的时候，一定要查看开关参数并调整到合适的状态，并对开关参数设置甲乙保护，谨防他人错误操作。

第三、供电系统的电源三相输出质量问题。比如三相电源电压不足，或者输出不平衡，继电器就会出现电压断开或是启动保护动作，从而导致冷冻机停机，出现这类问题，一般都是供电设备故障或是线路负载太重引起的。

以上就是科士达机房精密空调冷冻机启动时跳闸的原因之供电电源故障分析，为保证供电系统处于最佳的工作状态，来给冷冻机机组正常供电，请各用户在平时要按季度来对供电系统进行检查保养，及时发现问题并排除，避免因电源问题致使冷冻机机组不能正常运行。我们能够掌握排除冷冻机跳闸故障的方法，结合自身的具体能力，达到保障冷冻机顺利运行的目的，能够学会此类维修技巧，对于减少冷冻机故障起到至关重要的作用。

The tripping of the precise air-conditioning refrigeratory in Costa's engine room is a problem that many users may encounter when they first use the refrigeratory. There are many reasons for power failure of refrigerators in China, mainly in the following three aspects:
First, the three-phase power supply of the power supply system is out of phase. The commonly used power supply for refrigerators is 3-phase, 380V and 50HZ. If the power supply line is damaged, or the connection between switch and cable is loosened, as well as the contact fault of the switch itself, it will lead to phase absence, especially the fault of the switch itself is relatively common. This kind of fault can be found by multimeter.
Secondly, the parameter setting of the switch in the power supply system of the precise air-conditioning in the Kosta engine room does not meet the requirements. After eliminating the quality problem of the switch, the refrigeratory will start or trip. Then we need to check the parameter setting. If the allowable working current of the switch is less than the starting current, the start-up tripping will certainly occur; if the short delay current parameter is set too low, the refrigeratory will be affected by the impact current when it has low speed to high speed. Therefore, when overhauling, we must check the switch parameters and adjust them to the appropriate state, and set the A and B protection for the switch parameters, so as to guard against other people's wrong operation.
Third, the three-phase output quality of power supply system. For example, if the three-phase power supply voltage is insufficient or the output is unbalanced, the relay will have voltage disconnection or start protection action, which will lead to the freezer shutdown. This kind of problem is usually caused by the failure of power supply equipment or the overload of the line.
Above is the power supply failure analysis of the reason for the tripping of the precision air conditioner refrigeratory in the Kosta engine room. In order to ensure that the power supply system is in the best working state and to supply the refrigeratory unit with normal power supply, the users should check and maintain the power supply system quarterly in peacetime, find out the problems in time and eliminate them so as to avoid the failure of the refrigeratory unit due to the power supply problems. That's ok. We can master the method of eliminating the tripping fault of refrigerators, combine with our specific ability, achieve the purpose of ensuring the smooth operation of refrigerators, and learn such maintenance skills, which play a vital role in reducing the failure of refrigerators.
The new energy efficiency standard for precision air conditioning chillers in Costa engine room will be implemented on January 1, 2017 by GB19577-2015, issued jointly by the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee of China.
It is reported that the new standard will replace GB19577-2004 Energy Efficiency Limited Value and Energy Efficiency Level of Water Chillers. Compared with GB19577-2004, the main technical changes of the new standard are as follows: the energy efficiency limit value of the product has been revised; the energy efficiency grade judgment index of the product has been revised, from COP assessment to COP and IPLV assessment; and the energy efficiency grade of the product has been revised.
It is reported that the main enterprises in the field of precision air conditioning in Costa Machine Room have begun to break through the bottleneck of energy efficiency in research and development and achieved results. In 2014, the precision air-conditioning in the machine room launched the world's highest energy efficiency COP7.11 ultra-high efficiency bipolar compression falling film centrifugal unit, breaking the monopoly of foreign brands on the use of large-scale buildings with large cooling section centrifuge technology. This year, the fifth generation of high efficiency variable frequency direct drive falling film centrifugal unit was introduced for precision air conditioning in computer room, which broke through the energy efficiency bottleneck of small cooling capacity section in the industry. Its comprehensive energy efficiency IPLV increased from 7.5 to 10.69, and the operating noise decreased from 90 dB to 75 dB.
Kosta Precision Air Conditioner has introduced a full falling film magnetic suspension centrifuge, which achieves the maximum refrigeration capacity of 2210RT and the highest energy efficiency of IPLV13.18.
Professionals in the field of machine room precision air conditioning believe that the implementation of the new standards and major national brands'breakthroughs in improving energy efficiency technology will further promote the overall technical strength of our machine room precision air conditioning industry.
