  Screw compressor chillers can be divided into  air-cooled screw chillers  and  water-cooled screw chillers  according to different heat dissipation methods. According to different temperatures, it can also be divided into low temperature screw chillers, and according to the protection method, there are explosion-proof screw chillers.  Explosion-proof screw chillers  are mainly used in the chemical industry. The core components-compressors of these screw chillers are screw-type series of well-known brands, such as: Taiwan Hanbell screw compressor, Germany Bitzer screw compressor, the lubrication effect is very good, and the service life is over 20 years. When the compressor lubrication system of the screw chiller is better, it can reduce the friction force, friction heat and wear of parts of the compressor, better improve the mechanical efficiency of the compressor, and increase the reliability and working life of the compressor. The compressor lubric...

  Project Overview This project is for one of the new factory buildings for one of the 500 fortune company of  Dairy industry . The factory new workshop building area is about 17,000 square meters, with a total of 2 floors. H.Stars Group has helped this company to design the energy saving cooling system by adopting  low-temperature chiller  and low-ambient temperature air source heat pump unit Project Requirement Project design This project has air conditioning system, ice water system and hot water system, which has both cooling demand and heating load. The design of a system for the project can meet all the above requirements. Under the premise of ensuring safe and reliable operation, this scheme should balance the cold and heat as much as possible to make the system efficient and energy-saving. See the system flow chart for details. The whole project designs a refrigeration station, equipped with a flooded type  water-cooled low-temperature chiller  (wit...

  The  industrial chiller machine  has become one of the essential equipment for cooling in most production enterprises, and the screw chiller is a large-scale industrial refrigeration equipment. Screw chillers are divided into air-cooled screw chillers and water-cooled screw chillers. Compressors, condensers, and evaporators are important components of screw chillers. When purchasing a screw chiller machine, you must first understand the main control parameters of the screw chiller, such as refrigeration coefficient, cooling capacity, refrigerant, input power, etc. When choosing a screw chiller, we must consider the cooling capacity, the user's operating voltage, the outlet water temperature, and the condensing temperature. Use this to determine the model of the compressor, as well as the energy of the evaporator and condenser. The actual cooling capacity of the  screw chiller equipment  is related to the following factors: 1. Chilled water outlet temperature a...
