400kw 110Ton Water Cooled Glycol Chiller with Double Bitzer Screw Compressors

400kw 110Ton Water Cooled Glycol Chiller with double Bitzer Screw Compressors 

The water cooled screw chiller is open type water chiller, it including a semi-hermetic screw compressor and a shell and tube condenser & Evaporator, a electricity box with controller systems. We use PLC controller. When you install a water cooled screw chiller, you need to use an external water tank and usully 3 pumps for the water cooled screw chiller system.  The most important is that you need to connect a cooling tower to the chiller condenser for Heat dissipation. Compare with the air cooled screw chiller, the water cooled chiller is high efficient. but not easy to install. If you do not know how to install a water cooled screw chiller, you also can buy our Integrated water-cooled screw chiller machine.

Here are some key features and advantages of water-cooled screw chillers:

• Cooling System: Water-cooled screw chillers utilize a refrigeration system that consists of a compressor, evaporator, condenser, and expansion valve. The compressor compresses the refrigerant, which then flows through the evaporator where it absorbs heat from the process or the air conditioning system. The heated refrigerant is then sent to the condenser, where it releases heat to the cooling water. The water is circulated and cooled in a separate water loop.
• High Cooling Capacity: Water-cooled screw chillers are capable of providing high cooling capacities, making them suitable for large-scale applications that require significant cooling capacity. They can handle a wide range of cooling loads and maintain precise temperature control.
  
  
  
• Energy Efficiency: Water-cooled screw chillers typically have better energy efficiency compared to air-cooled chillers. The water-cooled design allows for efficient heat transfer to the cooling water, resulting in lower energy consumption. Additionally, water-cooled chillers often have variable speed drive compressors that can optimize energy usage based on the cooling load.
• Low Noise Levels: Water-cooled screw chillers tend to produce lower noise levels compared to air-cooled chillers. The condenser, which is the component generating most of the noise, is located in a separate area with the cooling tower or other water-cooling equipment, effectively reducing noise in the immediate surroundings.
• Space Requirement: Water-cooled screw chillers typically require a dedicated cooling tower or external water source for heat dissipation. This design allows for smaller physical footprint compared to air-cooled chillers, which need space for the condenser fan unit.
• Reliable Operation: Water-cooled screw chillers are known for their reliable operation and long service life. They are designed for continuous operation and can withstand high ambient temperatures and operating pressures. Regular maintenance and water treatment are essential to ensure efficient and reliable performance.
  
  
  
  
  

Products Specification 

The working principle of the water cooled screw chiller is: When the unit is refrigerated, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder. After the compressor performs work, the refrigerant vapor is compressed into high-temperature and high-pressure gas.

Enter the condenser through the exhaust pipe. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water, while the refrigerant gas is condensed into a high-pressure liquid. The high-pressure liquid from the condenser enters the evaporator after being throttled and pressure-reduced by the thermal expansion valve. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes, so that the chilled water is cooled down and becomes the required low-temperature water. The vaporized refrigerant gas is sucked in by the compressor again for compression, and discharged into the condenser, so that it goes round and round, and circulates continuously, so as to realize the cooling of the chilled water.
