H.Stars (Guangzhou) Refrigerating Equipment Group Ltd.

  Recently, when communicating with some customers, we found that we were not very clear about the type selection and system design of low temperature units. However, the   low temperature chiller   is a very important equipment for chemical industry, raw material pharmaceutical factory and other enterprises, and it is also the place with the largest energy consumption for such enterprises. Therefore, how to select the appropriate number of industrial low temperature chiller and design a reasonable frozen water circulation system is particularly important. There is an example on  H.Stars Group  project reference.To us, the key points of  glycol chiller  design ,take the recent project of Anhui Xiangbang Chemical Co., Ltd. as an example, the total cooling capacity demand of the enterprise is 1500kW, and the outlet water temperature is required to be - 15 ℃. According to the experience, the following three points are sorted out for your reference: 1、 Selection of the number of refrigerat

  The   heat recovery chiller   is a new type of energy recovery chiller. It has one more heat recovery device than conventional chillers，it is an   economical chiller . It can produce hot water for free at the same time when making cold water. The hot water temperature can reach up to 70 degrees. It is very suitable for hotels, guesthouses and pharmaceuticals, electronic constant temperature and humidity workshops and other places that have both cold and heat requirements. Heat recovery chillers types Heat recovery chillers can be divided into two types: partial heat recovery and full heat recovery according to the amount of recovery. Partial heat recovery can recover 30% of the heat energy of the cooling capacity, while full heat recovery can recover the cooling capacity + The equivalent amount of heat energy of the input power. The main features of the heat recovery chillers: The economic benefits of heat recovery chillers are not only energy recovery, but also reducing heat polluti

  In 2004, the Ministry of Construction issued a document that chilled water must be used in the concrete mixer projects such as subways, bridges, and dams. The chilled water varies according to the outdoor temperature across the country, and the general temperature is 2℃-7℃ . H.Stars Group  has not been involved in this market before, and customers know little about chillers, so ordinary customers buy ice cubes and ordinary tap water to solve the problem according to production needs. According to relevant statistics, this market is worth more than 3 million dollars per year. At present, only a few  concrete chiller plant  pays attention to this market. Since the chilled water temperature in this market is 2℃-7℃, the chillers are generally ammonia machines. Competing with other chiller manufacturers in this market, H.Stars Group concrete water chiller can directly supply 2°C water with advantages in terms of technology, equipment, solutions, and services. As long as this market and vi

  Introduction: Winter is coming, and the ambient temperature is about to drop below zero. This will cause great damage to the chillers, water pumps, cooling towers, terminals and other equipment. In order to ensure that chillers work normally during winter, the chiller has to survive in the low temperature environment, because it will cause a great loss to users if the unit is not maintained with proper seasonal shutdown. First of all, when those chillers are not going to turn on during winter for seasonal shutdown, water among chillers, pipes, pumps, cooling towers and terminals must be drained out clean in advance when the ambient temperature is below zero. How are we going to do for the water chiller HVAC system shutdown in winter ? Here are the tips below for seasonal water chiller system shutdown in winter how to drain out the water from HVAC system. 1.  Shell and Tube Condenser : Open the end cap of the water pipe.  After opening, pay attention to the end cover and screws. Insta

  From the perspective of design to talk about the special "intelligent" creation of H.Stars Group,which is related to compressor type selection. According to the conventional thinking, the choice of compressor type is not much difficult , small unit with scroll compressor, medium unit with screw compressor, large unit with centrifugal compressor. Why mention the compressor type choice again? Let's do a simulation selection. Suppose we need a  300KW water-cooled chiller Screw Type，40STD-280WS4，Cooling Capacity:284kW，Price is 15200USD Scroll Type，20STB-100WFO4，Cooling Capacity:300kW，Price is 13500USD From the data, the cooling capacity of the scroll type chiller is 6% larger than the  screw type chiller , and the price of the scroll type chiller is 13% lower than the screw type chiller. We believe you have a clear idea of which product is more competitive. It is also applied to  Air cooled chiller .The following introduces the scroll type chiller and screw type chiller coo

  We all know that winter swimming has many advantages: 1. It can enhance cardiovascular function. 2. The stimulation of cold water can close the peripheral blood vessels, increase the blood supply of important organs such as heart, brain, liver and spleen, so that more oxygen can be delivered to brain cells in time, which is conducive to the elimination of nervous system fatigue. 3. The skin of those who insist on winter swimming is ruddy, shiny and elastic. And people also hope to enjoy the fun of swimming in winter, but not everyone can bear it.  Hstars group constant temperature swimming pool heat pump  can be a good solution. 1. Demand analysis of swimming pool with constant temperature Constant temperature swimming pool, also known as indoor constant temperature swimming pool; that is, the temperature of the water in the pool heating system is maintained at 26~28℃, which is suitable for the temperature of the human body. When the indoor swimming pool is designed, the water body o

  In the production process of rubber and plastic seals and special rubber products, 15℃ constant temperature water is required to cool the rubber mixing process, so that the semi-finished product shape is fixed and instantly formed. If accurate low-temperature water cooling is not provided, the output and quality of the product will be seriously affected . At this time, a   rubber-plastic screw chiller   is needed to produce 15℃ constant temperature water. The rubber-plastic screw chiller is the energy-intensive part of the rubber seal. How can we make the cooling system work and save energy? H.Stars Group  has cooperated with internationally renowned rubber sealing materials and special rubber companies such as Zhongding Group and Cooper Group for 15 years. In this process, H.Stars Technology has accumulated a lot of experience, the choice of the chiller of the H.stars chiller manufacturer and the rationality of the circulation design are the key, and summarizes the design and select
