Audited Supplier 220HP -13degree C seawater water chiller cooling system low temperature water cooled screw chiller
A seawater water-cooled screw chiller is a type of chiller specifically designed to use seawater as the cooling medium. It is commonly used in marine or coastal applications where a reliable source of seawater is available for cooling purposes.
The main components and features of a seawater water-cooled screw chiller include:
Seawater Condenser: The chiller is equipped with a specialized condenser that is resistant to corrosion caused by seawater. This condenser efficiently transfers the heat from the refrigerant to the seawater, allowing the chiller to operate effectively. The materials of the sea water is 316 Stainless Steel.
Titanium Heat Exchanger/316 Stainless steel shell and tube evaporator: The heat exchanger used in the chiller is typically made of titanium or 316 Stainless steel shell and tube evaporator or other corrosion-resistant materials to withstand the corrosive nature of seawater. This ensures long-term durability and efficient heat transfer.
Seawater Circulation System: The chiller includes a dedicated seawater circulation system, which pumps the seawater from its source to the condenser and circulates it back. This system typically includes filters and strainers to prevent debris and impurities from entering the chiller unit.
Screw Compressor: The chiller employs a screw compressor as the main refrigeration component. Screw compressors are known for their high efficiency, reliability, and ability to handle varying loads, making them suitable for demanding industrial applications.
Control System: The chiller is equipped with a control system that allows for precise temperature control, monitoring, and diagnostics. It ensures optimal performance and energy efficiency of the chiller while providing protection against various faults or abnormal conditions.
The seawater water-cooled screw chiller finds applications in various industries, including offshore oil and gas platforms, marine vessels, coastal power plants, seafood processing plants, and other facilities requiring cooling in environments where seawater is readily available.
A low temperature water-cooled screw chiller is a refrigeration system designed to provide cooling for industrial processes or applications that require low temperatures. It typically consists of the following features:
Screw Compressor: The chiller utilizes a screw compressor which is highly efficient and capable of handling low temperature requirements. The screw compressor provides reliable and stable performance even at low temperatures.
Water-Cooled Condenser: The chiller is equipped with a water-cooled condenser that efficiently removes heat from the refrigerant. Water from an external source, such as a cooling tower or a closed-loop water circuit, is used to cool the condenser.
Refrigeration Circuit: The chiller's refrigeration circuit includes the evaporator, condenser, expansion valve, and compressor. The refrigerant circulates through these components, absorbing heat from the process and releasing it to the cooling water in the condenser.
Low Temperature Operation: The chiller is designed to achieve and maintain low temperatures, typically ranging from -40°C to -10°C (-40°F to 14°F). It is suitable for applications requiring precise and stable temperature control at extreme low temperatures.
Advanced Control System: The chiller is equipped with an advanced control system that allows precise temperature regulation and monitoring. It provides automated operation, fault diagnosis, and safety features to ensure efficient and reliable performance.
Corrosion Protection: As seawater can be corrosive, a seawater water-cooled screw chiller is designed with corrosion-resistant materials and coatings to withstand the corrosive effects of saltwater. This extends the lifespan of the chiller in marine or coastal environments.
Energy Efficiency: Low temperature water-cooled screw chillers are optimized for energy efficiency. They are equipped with energy-saving features such as variable speed compressors, heat recovery capabilities, and efficient heat exchange designs, reducing overall energy consumption and operating costs.
Customization Options: These chillers can be tailored to specific requirements with options for capacity, control systems, safety features, and integration with other equipment or processes.
The application of a low temperature water-cooled screw chiller includes various industries such as chemical processing, pharmaceuticals, food and beverage production, cold storage, laboratory testing, and other applications where precise and stable low-temperature cooling is required.
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.
The chilled water from the unit enters the indoor fan coils, variable air volume air conditioners and other terminal devices, and exchanges heat with convection air indoors. In this process, the water absorbs the heat of the indoor air (dissipates heat to the indoor air). While the temperature rises, the indoor air temperature drops after passing through the indoor heat exchanger, and is driven by the fan to send it into the room, thereby reducing the indoor air temperature, and the chilled water after the temperature rises reenters the unit under the action of the water pump. Circulation, so as to achieve the purpose of continuous refrigeration.
