JLSW-50D Water Cooled Screw Chiller Mold Cooling, Injection Molding, Blister Molding, Blow Molding


Product Description:


Water-cooled screw chiller is a kind of refrigeration equipment for industrial use, mainly used to provide cooling and air conditioning services for large buildings such as factories, commercial centers, and office buildings. It lowers the temperature of water by circulating refrigerant, so that cold water is delivered to the area that needs to be cooled to achieve the effect of cooling, dehumidification and keeping the air fresh.

The main components of a water-cooled screw chiller are compressors, condensers, evaporators, and throttle valves. Among them, the screw compressor is the core part of the whole system, which increases its temperature and pressure by compressing the refrigerant, makes it dissipate heat in the condenser and cools it down, and then absorbs heat in the evaporator and lowers the temperature, forming cold water recirculation use.

The water-cooled screw chiller has the characteristics of high cooling efficiency, large cooling capacity, stable operation, low noise, and easy maintenance. It is suitable for places that require a lot of cooling, such as large buildings and industrial manufacturing enterprises. However, its installation and use costs are high, and it requires a large space and power energy support, so it is generally used for large-scale projects and commercial purposes.


 

 

 

Production Features:


Water-cooled screw chiller has the following characteristics:

1.High refrigeration efficiency: The water-cooled screw chiller uses a screw compressor, which has the advantages of high efficiency, low noise, low vibration, and good stability. It can quickly cool down and meet large-scale refrigeration needs.

 

2.Large refrigerating capacity: The water-cooled screw chiller has a large refrigerating capacity and is suitable for places requiring a large amount of cooling, such as large buildings and industrial manufacturing enterprises.

 

3.Good stability: The key components such as the compressor, condenser and evaporator of the water-cooled screw chiller are made of high-quality materials, with high durability and stability, and can run stably for a long time.

 

4.Simple maintenance: The maintenance of the water-cooled screw chiller is relatively simple. It only needs basic maintenance such as regular cleaning, inspection and filter replacement to maintain its normal operation.

 

5.Environmental protection and energy saving: The water-cooled screw chiller uses environmentally friendly refrigerants and has a high energy efficiency ratio. At the same time, it can realize energy saving and environmental protection benefits through linkage control with other systems.

 

6.Strong adaptability: The water-cooled screw chiller can be combined in various forms according to the needs to meet the refrigeration requirements of different occasions and different needs. It is a highly flexible refrigeration equipment.

 

 

 

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.

Maintenance Method:


The maintenance of the water-cooled screw chiller is very important for its long-term stable operation. The following are some common maintenance measures:

1.Regularly clean the condenser: The condenser is one of the most vulnerable parts of the water-cooled screw chiller to be polluted and fouled, so it needs to be cleaned regularly. When cleaning, first turn off the power and drain the water in the chiller, then use professional cleaning agents and cleaning tools to clean, and then rinse with clean water after cleaning.

 

2.Check the pressure of the refrigerant: The pressure of the refrigerant has a great influence on the cooling effect and energy consumption of the chiller, so the pressure of the refrigerant should be checked and adjusted regularly to ensure that it is within the normal range.

 

3.Regularly replace the filter element: The filter element in the water-cooled screw chiller plays the role of filtering impurities in the water, so it needs to be replaced regularly to avoid the clogging of the filter element and affect the water flow and cooling effect.

 

4.Check the wires and electrical parts: The wires and electrical parts of the water-cooled screw chiller are susceptible to moisture and corrosion, so they need regular inspection and maintenance to ensure that they are safe and reliable.

 

5.Regular inspection of cooling towers: Cooling towers in water-cooled screw chillers are susceptible to contamination and fouling, so they need to be inspected and cleaned regularly to ensure they are functioning properly.
