    H.Stars Group Back to Work from Chinese Spring Festival
    With a half month Chinese Spring Festival , H.Stars Group has finally come back to work as normal. Here we wish everyone a Happy New Year and prosperous business in 2021 ! The first working day, every staff met the president of H.Stars Group ,Mr. Yuen , greeting him a happy new year and prosperous business in the coming year. Instead, the president give each person a red envelop with lucky money inside. This "red packets" is a Chinese New Year customs, Chinese favorite red, because red symbolizes vitality, happiness and good luck, which also what the president Mr. Yuen wishes everyone the same. In the first working day ,the president Mr. Yuen has given away red lucky money to all the staff. Note: The Chinese Spring Festival is the most important festival for the Chinese people ,because it is a time for all family members to stay together, just like Christmas in the West. All people living away from home go back, and spend half a month time with family members during the Spring Festival. The Spring Festival falls on the 1st day of the 1st lunar month, often one month later than the Gregorian calendar. It originated in the Shang Dynasty (c. 1600 BC-c. 1100 BC).The most important days are Spring Festival Eve and the first three days. The Chinese people  decorates and cleans their rooms featuring an atmosphere of rejoicing and festivity. All the door panels will be pasted with Spring Festival couplets, highlighting Chinese calligraphy with black characters on red paper. The content varies from house owners' wishes for a bright future to good luck for the New Year.

  • The Importance of Chiller Maintenance |
    The Importance of Chiller Maintenance |
    In summer and winter, it is the busiest time for our after-sales. Because many customers use the unit incorrectly and cause chiller failure. So let's talk about the importance of unit maintenance, how to ensure that the chiller is always in the best condition, maintain the highest efficiency, and extend the life of the chiller. Maintenance refers to preventive maintenance of the unit, and the customer is responsible for formulating unit maintenance procedures based on actual conditions. Qualified equipment management engineers and specialized unit operators are required to perform routine maintenance and regular maintenance on the unit. The maintenance of the unit should be carried out by a qualified chiller maintenance companies. The most basic work in the maintenance of the industrial chiller is to actually record the operating parameters of the unit at appropriate intervals (for example, one hour) every day, and fill in the unit operating parameter table. The operating parameter table can refer to the "H.Stars chiller operating parameter record table" to compile the customer's own suitable format. A true and complete record of operating parameters helps to analyze the possible development trend of the unit's operation, and helps to discover and predict the possible problems of the unit in time, so as to prevent it before they happen. For example, through the analysis and comparison of one-month operation records, it may be found that the difference between the condensing temperature of the unit and the cooling water outlet temperature is increasing. This trend indicates that the cooling water may be dirty or harder, and the condenser tube bundle Scaling is continuing, and the water needs to be softened or cleaned. Poor quality of chilled water and cooling water will not only cause scale in the heat transfer tubes, affect heat exchange efficiency and reduce unit performance, but also corrode the heat transfer tubes and cause major failures of the unit. Customers should perform water quality treatment in accordance with the requirements of GB50050-1995 "Code for Design of Industrial Circulating Cooling Water Treatment". When the chilled water system is a closed system, soft water should be used. If the requirements are not met, water quality treatment should be performed. In addition to the maintenance of the cooling water circuit, there is of course the maintenance of the compressor. The refrigerating oil is like the blood of the compressor. Long-term operation will cause loss and produce a lot of impurities. Regular cleaning and replacement of the refrigerating oil will effectively extend the service life of the compressor so that the operation of the unit remains stable to the maximum extent.
  • How to do daily maintenance of air-cooled chillers |
    How to do daily maintenance of air-cooled chillers |
    Air-cooled chillers, as a more efficient refrigeration equipment in chiller products, are widely used in the domestic industrial market and become necessary equipment for many industrial production. At the same time, although the industrial air-cooled chiller is equipped with multiple protection devices, these are all to prevent failures from directly damaging the unit. If the company wants to ensure that the air-cooled chiller with high cooling efficiency and long service life, then it must remember to do regular maintenance. Therefore, how should the normal safety maintenance and inspection of air-cooled chillers be carried out? 1) Check the stability of voltage and current When the air-cooled chiller works normally, the voltage is 380V (the voltage of DYJ-01A~DYJ-02A is 220V, and the voltage of other regions abroad also has 410V, etc.), and the current is normal within the range of 11A-15A; 2) Check the compressor regularly The compressor is the "heart" of the chiller, and its quality directly affects the stability of the chiller. The necessary acceptance test for the chiller should be carried out in accordance with the principle of air tightness test first, vacuum test second, sub-item test first, and complete machine test second. 3) Clean regularly In addition to checking the technical performance of the chiller, it is also important to protect the clean appearance of the chiller and the cleanliness of the work site. When the air-cooled chiller is running for 6 months, the entire system must be cleaned, such as pipes, filters, condensers, fans, etc., especially fans. Like our commonly used fans, dust will affect heat dissipation, so the cooling efficiency will Direct reduction 4) Check the meter regularly The temperature control meter is out of control. Replace the temperature control meter. High pressure failure. Poor heat dissipation. The radiator is too dirty. The cleaning radiator is not good enough. Improve the ventilation conditions. The heat dissipation fan does not work. , Replace the high-pressure engine. 5) Check whether the refrigerant has decreased or not regularly Judge according to the high and low pressure gauge values on the front of the air-cooled chiller. When the chiller is running normally, the high pressure is 11-17kg, and the low pressure is 3-5kg. In shutdown state, both high pressure and low pressure are around 0.6kg. The high-efficiency refrigeration function of air-cooled chillers is inseparable from the daily maintenance and safety inspection of the products, so it is very important to check the operation of air-cooled chillers. In addition to the main inspections above, it is also necessary to check the oil level and oil temperature of each compressor, check the main power supply voltage and current, and check whether the set value of the chilled water supply temperature is appropriate. If there is a problem, make changes in time. If you encounter a problem you don't understand, you can consult H.Stars  Group...
