Product Description:

Water-cooled screw chiller is a common cooling equipment, which combines screw compressor and water-cooled heat dissipation technology. It is mainly composed of screw compressor, condenser, evaporator, cooling water circulation system and control system.

The following is a general description of a water-cooled screw chiller:

1. Screw compressor: The water-cooled screw chiller uses a screw compressor as the main compression device. The screw compressor compresses the refrigerant through two intermeshing screw rotors to increase the pressure and temperature. Screw compressors are highly efficient, reliable and can provide stable cooling.

2. Condenser: The condenser is the radiator part of the water-cooled screw chiller, which is used to release heat and cool down the high-temperature and high-pressure refrigerant compressed by the compressor. The condenser usually adopts the structure of pipes and fins, and the refrigerant is dissipated and cooled by circulating water flow.

3. Evaporator: The evaporator is the cooling part of the water-cooled screw chiller, which is used to absorb the heat generated by the cooled equipment or system. In the evaporator, the refrigerant changes from liquid to gas, absorbing heat and carrying it away, thereby reducing the temperature of the equipment or system being cooled.

4. Cooling water circulation system: The water-cooled screw chiller maintains cooling effect through the cooling water circulation system. The circulating water pump draws the cooling water out of the condenser, and after passing through the evaporator to absorb heat, it flows back to the condenser to dissipate heat, forming a cycle.

5. Control system: Water-cooled screw chillers are usually equipped with advanced control systems for monitoring and regulating the cooling process. The control system can realize temperature control, pressure control, flow control and other functions to ensure the stable operation and efficient performance of the chiller.

It should be noted that the water-cooled screw chiller needs a stable water supply and drainage system to ensure its normal operation. In addition, according to specific application requirements, water-cooled screw chillers can also be equipped with additional functions, such as joint operation of multiple units, energy efficiency optimization, etc.

Production Features:

Advantages of water-cooled screw chillers:

1. Heat dissipation efficiency: The water-cooled screw chiller transfers heat to the cooling water through the water cooler, and then discharges the heat through the cooling water circulation system. Due to the higher specific heat capacity of water, water cooling usually has higher heat dissipation efficiency and can remove heat more effectively.

2. System stability: The water cooling system is more stable than the air cooling system. The water-cooled screw chiller can provide a stable cooling water temperature through the water circulation system, and is not sensitive to changes in ambient temperature and humidity. This makes water-cooled systems more suitable for long-running and temperature-controlled applications.

3. Quiet operation: Water-cooled screw chillers are generally quieter than air-cooled chillers. Since the heat dissipation part of the water cooling system is located outdoors, the impact of noise on the indoor environment is small, and it is suitable for places with high noise requirements.

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.

Techinical Parameters:

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.
