JLSW-200D Efficient And Easy-To-Maintain Water-Cooled Screw Chiller For Large Commercial Buildings

Product Description:

Water-cooled screw chiller is a type of refrigeration equipment that uses water cooling and uses a screw compressor as the main refrigeration method. It is mainly composed of screw compressor, condenser, evaporator and control system.
The screw compressor is the core component of the water-cooled screw chiller. It compresses the refrigerant through a rotating screw, increasing the temperature and pressure of the refrigerant. Screw compressors have efficient and stable refrigeration performance and are suitable for large-scale refrigeration systems.

Production Features:

A water-cooled screw twin-head chiller is a chiller configuration that has two independent screw compressor heads to provide refrigeration capacity. The following are some descriptions of water-cooled screw double-head chillers:
1. Double-head configuration: The water-cooled screw double-head chiller has two independent screw compressor heads. Each machine head includes a main screw and a slave screw, which can operate independently or simultaneously to provide refrigeration capacity according to actual needs.

2. Independent control: Each machine head has an independent control system and can be adjusted and controlled independently. This means that under different workload conditions, you can choose to use one machine head or two machine heads at the same time according to your needs to achieve better energy efficiency and precise cooling control.

3. Load balancing: Double head chillers are designed to achieve load balancing. When load demand is low, only one machine head can be used to reduce energy consumption. When load demand increases, both heads can be started simultaneously to meet higher cooling needs.

4. Reliability and backup: The dual-head configuration provides system redundancy and backup functions. If one machine head needs repair or fails, the other machine head can continue to operate to ensure system reliability and continuous cooling capacity.

5. Capacity adjustment: The double-head chiller also has a capacity adjustment function, which can be adjusted according to actual needs. By controlling the number and operating status of the machine heads, the refrigeration capacity can be flexibly adjusted to adapt to different process requirements or changing load demands.

Water-cooled screw double-head chillers are suitable for applications requiring higher cooling capacity and more flexible control. They are commonly used in large industrial productions, commercial centers, medical facilities and other places where stable, reliable refrigeration systems are required. This configuration provides increased cooling capacity and system redundancy to ensure continuous, efficient cooling operation.

Working Principle:

The working principle of the water-cooled screw chiller mainly includes four processes of compression, condensation, expansion and evaporation.
1.Compression process: Under the action of the screw compressor, the refrigerant is compressed into a high-temperature and high-pressure gas, while absorbing the surrounding heat.

2.Condensation process: High-temperature and high-pressure refrigerant enters the condenser, and through contact with cold water or surrounding air, it emits heat and cools into a high-pressure liquid.

3.Expansion process: The high-pressure liquid refrigerant enters the evaporator through the throttle valve, the pressure drops suddenly, and the liquid refrigerant expands into a low-pressure refrigerant while absorbing the surrounding heat.

4.Evaporation process: The low-pressure refrigerant enters the evaporator, absorbs surrounding heat through contact with water or air, turns into a low-temperature and low-pressure refrigerant, and returns to the compression process.

Through such a cycle process, the water-cooled screw chiller can deliver cold water to the area that needs to be cooled to achieve the effects of cooling, dehumidification and keeping the air fresh. At the same time, the water-cooled screw chiller will also emit a certain amount of heat, which needs to be dissipated through cooling towers or other heat dissipation equipment to ensure the normal operation of the system.

Application Industry:

Water-cooled screw twin-head chillers are suitable for many different applications. Here are some common application scenarios:
1. Large commercial buildings: Double-head chillers are often used in large commercial buildings, such as shopping malls, office buildings, hotels, and exhibition centers. These buildings often require high refrigeration capacity to meet the large cooling demands, such as central air conditioning systems, cooling towers and other refrigeration equipment.

2. Industrial production: Many applications in the industrial field require a large amount of cooling capacity, such as manufacturing, chemical plants, electronics factories, and pharmaceutical factories, etc. The double-head chiller can provide efficient refrigeration capacity to meet the cooling needs in these industrial production processes.

3. Medical facilities: Hospitals, laboratories and medical facilities often require precise temperature control and stable refrigeration systems. The dual-head chiller can provide reliable cooling capacity to ensure the normal operation of medical equipment and provide a comfortable environment for patients and medical staff.

4. Data Center: Data centers require powerful cooling capabilities to maintain normal operating temperatures of servers and network equipment. The dual-head chiller can meet the data center's need for efficient cooling and ensure equipment reliability and performance.

5. Refrigeration process: The double-head chiller can also be used in various refrigeration processes, such as food processing, beverage production and refrigeration storage. In these applications, precise temperature control and high refrigeration capacity are key to ensuring product quality and safety.

Overall, water-cooled screw twin-head chillers are suitable for applications that require large amounts of cooling capacity, flexible control, and reliability. They play an important role in large commercial buildings, industrial production, medical facilities, data centers and refrigeration processes. The specific application needs and size will determine the capacity and configuration of the dual-head chiller selected.
