JLSW-40D Screw Type Low Temperature Chiller Ethylene Glycol Chiller

Product Description:

The low-temperature screw chiller is a refrigeration equipment specially designed to provide low-temperature cooling. It uses a screw compressor as the core component to achieve refrigeration by compressing and expanding refrigerant. The following is a description of the low temperature screw chiller:

1. Screw compressor: The low temperature screw chiller uses a screw compressor as the main refrigeration unit. The screw compressor rotates by two intermeshing screws to generate a compression action, which compresses the refrigerant gas and increases its temperature and pressure.

2. Low-temperature refrigerant: Low-temperature screw chillers usually use low-temperature refrigerants, such as R404A, R507A, etc. These refrigerants have low boiling points and evaporation temperatures that provide the desired low-temperature refrigeration.

3. Piping system: The low-temperature screw chiller includes a piping system for refrigerant circulation, which is used to transfer refrigerant from the compressor to the cooling part and expansion valve, and complete the return process.

4. Cooling components: The cooling components of the low-temperature screw chiller include condensers and evaporators. The condenser is used to cool the high-temperature and high-pressure refrigerant gas discharged from the compressor and convert it into a high-pressure liquid, while the evaporator is used to evaporate the refrigerant liquid to absorb the heat of the surrounding environment, thereby achieving the cooling effect.

5. Temperature control: The low-temperature screw chiller is equipped with a temperature control system, which can precisely control the temperature of the cooling water according to the needs. By monitoring and adjusting the pressure and flow of refrigerant, a stable low-temperature cooling effect can be achieved.

Low-temperature screw chillers are widely used in industrial production and laboratory applications that require lower temperatures, such as frozen storage, chemical manufacturing, food processing, pharmaceutical research and development, etc. They provide reliable cryogenic cooling for application-specific temperature control and stability requirements.

Production Features:

Low temperature screw chiller has the following characteristics:

1. Low-temperature cooling capacity: Low-temperature screw chillers are specially designed to provide low-temperature cooling, capable of meeting lower cooling temperature requirements, usually in the range of -40°C to -80°C.

2. High efficiency and energy saving: As the core component, the screw compressor has efficient refrigeration performance and energy consumption ratio. It can provide large cooling capacity while having low power consumption to achieve efficient energy utilization.

3. Stability and reliability: The low-temperature screw chiller adopts advanced control system and stable refrigeration technology, which can provide stable low-temperature cooling effect and has good operational reliability.

4. Excellent temperature control performance: Equipped with a sophisticated temperature control system, it can achieve precise control and stability of the cooling water temperature and meet the requirements of specific applications for temperature accuracy and stability.

5. Multiple protection functions: Low-temperature screw chillers are usually equipped with multiple protection functions, such as over-current protection, over-temperature protection, low-temperature protection, etc., to ensure the safe operation and long life of the equipment.

6. Durability and easy maintenance: Using high-quality materials and manufacturing processes, the low-temperature screw chiller has strong durability and corrosion resistance. At the same time, the equipment has a reasonable structure and is easy to maintain and maintain.

7. Wide range of application fields: low-temperature screw chillers are suitable for many industrial fields, such as chemical, pharmaceutical, food processing, electronics, frozen storage, etc., to meet the needs of different industries for low-temperature cooling.

To sum up, the low-temperature screw chiller has the characteristics of low-temperature cooling capacity, high efficiency and energy saving, stability and reliability, and high temperature control accuracy. It is suitable for industrial applications that require low-temperature cooling and is widely used in many industries.

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:

In the battery manufacturing process, the chiller can be used for the cooling of the following equipment and workpieces:

1. Electrode coating machine: The electrode coating machine is used to coat the electrode material on the electrode sheet of the battery. During this process, the coating machine generates heat, which requires cooling to maintain the stability of the coating process and the quality of the electrode sheet. Chiller can be used to cool the roller and coating head part of the electrode coating machine to ensure that the temperature is controlled within an appropriate range.

2. Hot press: The hot press is used to heat press the electrode sheet, separator, current collector and other components to form a battery sheet. During the hot pressing process, due to the high temperature and pressure, a lot of heat will be generated. The chiller can be used to cool the heating plate and cooling plate of the heat press machine to control the temperature during the heat press process and ensure the quality and consistency of the battery sheet.

3. Vacuum furnace: In battery manufacturing, some processes need to be carried out in a vacuum environment, such as drying and sintering. Vacuum furnaces generate heat during these processes and require cooling to maintain a stable temperature inside the vacuum furnace. The chiller can be used to cool the cooling system of the vacuum furnace to ensure process stability and product quality.

4. Battery packaging equipment: In the final stage of battery manufacturing, batteries need to be packaged, such as in metal casings or plastic casings. During the packaging process, some equipment will generate heat and need to be cooled to ensure the stability of the packaging process and the quality of the product. Chillers can be used to cool packaging equipment and maintain the temperature within an appropriate range.

These equipment and workpieces are involved in the generation of heat during the battery manufacturing process, and need to be cooled by chillers to maintain the stability of the process and the quality of the product. Chillers play an important role in the battery manufacturing industry.
