  The 21st century is a century of rapid technological development. The global population has exceeded 6 billion, and the shortage of land resources has increasingly become a common concern of all countries. The utilization of underground space will also be paid more attention. Country's tunnel construction has achieved leap-forward development in recent years. As of 2019, there are 56 cities in mainland China with a total line size of 6,902 kilometers. Among the 6,902 kilometers of construction lines, underground lines are 5,632 kilometers, accounting for 81.6%, and ground lines are 416 kilometers, accounting for 6%; elevated lines 853.2 Kilometers, proportion, 12.4%; The estimated demand for  water-cooled screw chiller  in this market is USD 5 million per year. At present, we have a model case and hope to achieve excellent performance in this sub-industry. H.Stars Group has invested capital in this industry since the last few years . Below is one of H.Stars Group projects done de

  More dust and poor water quality in  the chiller environment will affect the normal operation of the equipment, and even lead to downtime. In order to increase the operating power of the chiller, it is necessary to create high-quality conditions for use and effectively maintain the operating power of the  air-cooled chiller . ​ When using the chiller, if there is a lot of dust and other problems in the environment during the operation of the equipment, the normal operation of the equipment will be affected after the equipment enters the water-cooled chiller. In order to prevent the chiller equipment from being affected by dust in the environment and a large amount of scale due to long-term lack of maintenance, companies need to conduct professional inspections on chillers on a regular basis. A layer of solid or ooze builds up, called fouling, which adds additional fouling thermal and flow resistance, increasing required heat transfer area, power consumption and maintenance cleaning c

  Air-Cooled scroll chiller   VS   Air-Cooled Screw Chiller Functionally: The air-cooled screw chiller and the air-cooled scroll chiller have the same cooling function. The cooling, heating and energy are all electric energy. Application industry: are mainly used in industry, medicine, plastic, food, coal, shopping malls and other industries. It can be installed on the roof or outdoor courtyard, without the need for a dedicated machine room and cooling tower. The smallest air-cooled screw chillers are 30HP/30Ton, while air-cooled scroll chillers range from 1HP/1Ton to 60HP/60Ton. The two categories differ on the basis of capacity range. Another difference is that screw chillers do not have a built-in water tank and water pump, while air-cooled scroll chillers have a water tank and water pump. Furthermore, it has a compact design, so it is easy to integrate. Unlike screw chillers with touch screens, air-cooled scroll chillers are equipped with an easy-to-use PID controller. The O umal 

  Water-cooled chiller   is a cooling water device that can provide constant temperature, constant current and constant pressure. A chiller is a machine that achieves refrigeration through vapor compression or absorption cycles. These liquids can flow through heat exchangers to cool the air or equipment. The industrial chiller can always output ice water with a lower temperature than the ambient temperature. It can be used wherever cooling is required, either direct cooling or indirect heat exchange. The main components of a water-cooled chiller are compressor, condenser, evaporator, water pump, and water tank. Chillers have a wide range of applications. The chiller can be used to cool the injection mold, improve the quality of plastic products, cool the vacuum coating, control the temperature of the vacuum coating machine, cool the food industry, fast cooling processing, chemical industry, effectively control the temperature of chemicals, cooling buildings, concrete fast Cooling and c

  Water-cooled chillers  are equivalent to air-cooled chillers, which are safer in operation and more conducive to maintenance and repair. ​ The high-quality compressor is the heart of the water-cooled chiller, and the compressors are all high-quality brand compressors.  For scroll compressor water cooled chiller, We use Copeland, Danfoss, Panasonic, Daikin Brand, For screw compressor water cooled chiller, Bitzer and Hanbell or Refcomp compressor is the widely used in our  screw water cooled chiller systems . The water-cooled chiller condenser is made of high-efficiency external threaded copper tube, which is very small in size and has a very fast heat dissipation speed. It uses new CAD/CAM processing technology and is completed with CNC machining center. It has compact structure, high reliability, beautiful appearance and high efficiency. Energy saving, good heat dissipation, the refrigerant pressure is lower than that of air cooling, the energy efficiency ratio is higher than that of

 The  water-cooled chiller system  is an industrial cooling system composed of a water-cooled chiller, a water tank, a water pump, and a cooling tower. The water-cooled chiller is based on the cooling method of the condenser, which uses cooling water to take away the heat (cooling tower), rather than the fan to take away the heat, which is relative to the air-cooled chiller. Water-cooled chillers include Packaged water-cooled units, open-type water-cooled units, and screw-type chillers. The water-cooled chiller is composed of a compressor, an evaporator (the evaporator can be a water tank coil, a plate heat exchanger, or a shell and tube evaporator), a shell and tube condenser, an electric control part, and a water pump (can be external, not It is made on the chiller), and the water tank (generally, the box-type chiller will have a built-in water tank, and the open-type chiller or screw-type chiller will need an external water tank). Today we will talk about water-cooled screw chillers
