  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

  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-hermetic

  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 lubrication method of the screw chiller

  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  (with heat recovery) + a low-ambi
