Debugging method of the latest screw type cold water machine
     The operating condition parameters of the cooling system of the industrial chiller are very good. The main purpose of the refrigeration system is to adjust the parameters to make it run in the most reasonable conditions. Especially for those large screw type chiller, debugging is not good, will directly affect the cooling effect.
     (1) refrigerant charging. At present, the refrigeration unit in the factory are generally in accordance with the provisions of the refrigerant filling, on-site installation, inspection if no accident damage, you can directly open the valve (you should read the instructions in transit units on the valve in the closed state general commissioning). If it is found that the refrigerant has been leaking end or insufficient, should first find the leaks and eliminate the leakage phenomenon, and then press the cold water machine instructions, with the stipulated quantity of refrigerant refrigerant. Attention should meet the technical requirements.
     (2) some screw chillers need to be charged with refrigerant on the user's site, and the refrigerant charge and refrigerant grade must be in accordance with the regulations. Insufficient refrigerant charge. Too much refrigerant charge, will not only increase the cost, but also on the operation of industrial water chiller energy consumption may adversely affect.
     (3) sufficient refrigerant should be prepared in advance before the industrial chillers are charged with refrigerant. When charging, can be directly from the dedicated filling valve filling. Because the system is in a vacuum state, and the refrigerant cylinder pressure, when the valve is opened (should first use of refrigerant blown connecting pipe in the air, in order to avoid the air into the unit, the unit performance effect), the refrigerant from the cylinder rapidly flow system, charging is completed, should be the first liquid filling valve is closed. Then remove the connecting pipe.

      (4) refrigeration system commissioning. After the completion of the refrigerant charge (if you need to charge refrigerant), you can load commissioning. In recent years, screw chillers in terms of performance and electrical control have made considerable progress, many screw chillers can do simulation test of the main action of electric control system in the official before the start, the host unit without electricity, electricity control system, and then through the machine electric control system of the group internal setting unit to detect whether the normal operation, assembly. If there is any problem with the electronic control system, it can be solved in time. Finally, through the host power supply for debugging.

      What is the environment suitable for the use of air-cooled chillers?
      Due to the high stability of the air-cooled industrial chillers, the industrial chillers are suitable for different operating environments. Therefore, when the enterprise chooses the industrial cold water machine, it will be the main type of product. In the two aspects of stability and high power selection, enterprises tend to long-term stability of the industrial chiller as the main criteria for selection.
      Operation stability of air cooled Industrial Chiller
      Due to the use of air cooling mode, so the industrial chillers are not subject to any environmental restrictions. As long as there is air circulation position, enterprises are able to complete the installation of industrial chillers equipment. Of course, the higher the ventilation coefficient of the environment, air-cooled industrial chillers operating efficiency is higher, for the enterprise to create a low temperature environment for a very short time.
     Many domestic large enterprises use the environment can not provide high quality water, so the need to choose air-cooled industrial chillers for auxiliary production. In particular, all kinds of chemical industry, the national requirements of various types of enterprises with serious pollution must be away from the city, in the countryside it is difficult to obtain the quality of water, so the use of air-cooled industrial chillers, can help enterprises to efficiently complete the work, while avoiding the waste water.
      Air cooled industrial chillers are widely used
      Out of the water and water quality requirements, the quality of industrial water chillers for different enterprises to provide long-lasting low temperature environment. Even with high corrosion of industrial enterprises, the same can use air-cooled industrial chillers equipment. After a special industrial processing, most of the enterprises have been able to use air-cooled industrial chillers to complete production, and the efficiency is very high.
      Even in a highly corrosive environment, the quality of industrial chillers can also maintain stable operation. Although the environment has an impact on the operating efficiency of industrial chillers, but after production enterprises in the processing, based on low energy consumption, industrial chillers can meet most of the needs of enterprises, reduce the overall cost and the use of industrial cooling water machine.
      From the operation of the safety and cost considerations, enterprises choose air-cooled industrial chillers are very good, can provide technical support for the enterprise to complete all production tasks to achieve high efficiency, to avoid any impact on production. Especially for a lot of enterprises in the production environment, the quality of air-cooled industrial chillers can also maintain the stability and safety of the operation, reduce the cost of the use of industrial chillers.

       Service life of industrial chillers
       When we use cold water machine, there is no specific use of the plan, will result in equipment running too long. The service life of the chiller is 10-15 years. The following East Star to introduce the life of industrial chillers and those factors are related!
      1 compressor
      The compressor is the heart of the chiller, its quality is good or bad, is a measure of the chiller service life is very important. On the basis of temperature range of the compressor we divided into three types: high temperature, medium temperature and low temperature compressor, but in a specific region and the evaporation temperature is not uniform, the temperature range is: high temperature compressor -10 to 10 DEG C; the temperature of compressor -20 to -10 DEG C; low temperature compressor -45 ~ -20 degree; the user temperature on the chiller compressor with different requirements are not the same.
      2 run time
      Many companies believe that the performance of the chiller is relatively stable, even if there is no rest time, cold water machine also has a longer service life. However, after an authoritative investigation found that the rational use of cold water machine and the enterprise does not have any plans to run cold water machine, with the life of the equipment is very different. Regular maintenance and maintenance of the cold water for the enterprise, even if the operation of the daily running of the cold water to keep the time in 20 hours or more, the device can also maintain very little trouble within 4 years. For 24 hours a day to run the cold water machine, and more than 7 days without providing any rest time of the enterprise, cold water machine may often appear all kinds of small fault.
      3 energy consumption
      When using the water chiller, first need to use the environment space size, operating power adjusting equipment in time, if the space is larger, so when using the water chiller, can increase the operation of power equipment. To deal with the failure of cold water units need to do a good job in advance to prevent the work, according to the size of the use of the environment, the first to develop a good plan for the use of the equipment within the scope of the plan to achieve stable operation.
     4 internal scale
     In the use of cold water machine, if the operation of the equipment for more than half a year, then there will be a large number of water chiller evaporator scale. If the scale is not carried out in a timely and effective manner, the stability of the equipment will be seriously affected. When the equipment to malfunction, even if the enterprise can carry out effective treatment according to the fault, still can not guarantee the equipment rapid reduction in the temperature of the space, and even lead to a lot of enterprise energy utilization has been reduced.
