  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 ...

 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 ...

  Advantages and disadvantages of piston chillers According to the different types of chiller compressors, industrial chillers can be divided into fully enclosed scroll chillers, semi-enclosed piston chillers, and semi-enclosed screw chillers. All kinds of compressors have their advantages and disadvantages. Today, Omar Refrigeration will take you to talk about the advantages and disadvantages of  piston chillers . Piston chiller is a chiller with semi-hermetic piston compressor as the main engine. The unit is composed of refrigeration compressors, condensers, evaporators, thermal expansion valves, etc., and is equipped with automatic energy regulation and automatic safety protection devices. The piston compressor device system is relatively simple, and this type of compressor is generally used more in low temperature conditions. For general piston compressors, the brands we use are Bitzer Semi-hermetic Piston compressor, Copeland Semi-hermetic Piston compressor, or Dorin semi...

  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...

  In the process of using the chiller, have you encountered the problem that the chilled water of the chiller does not circulate? How to solve the problem of the chilled water not circulating? We all know that under normal circumstances, small industrial chillers have been equipped with chilled water circulation pumps, such as Packaged air-cooled chillers,  box-type water-cooled chillers , and large capacity chillers such as  screw chillers  and open-type water chillers. The chiller does not contain a chilled water circulating pump. At this time, when installing the cooling water system, an external chilled water circulation pump must be installed, so that the cooling water returns to the chiller for cooling after absorbing the heat of the cooling equipment, so that the cooling water supply pipe forms a circulation system. It should be noted that no matter whether the chilled water pump is inside the built-in chiller case or outside the chiller, it is recommended tha...
