Product Specification

JLSW-40D Water Cooled Screw Chiller Cold Storage, Refrigeration Equipment, Freeze Drying Equipment

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:

Screw compressors have some unique advantages and disadvantages compared to other types of compressors, here are some common comparisons:

Advantage:
1. High-efficiency capability: Screw compressors perform well in energy conversion, have high-efficiency energy conversion capabilities, can provide high cooling capacity, and show advantages in energy consumption.

2. Wide working range: The screw compressor has a wide working range, can run stably under different load conditions, and can automatically adjust the cooling capacity to meet actual needs.

3. Low vibration and noise: The structural design of the screw compressor makes the vibration and noise low during operation. Compared with other types of compressors, the working process is relatively stable, which reduces the interference of the machine on the surrounding environment.

4. High reliability and durability: Screw compressors usually use high-quality materials and manufacturing processes, have high reliability and durability, can run stably for a long time, and require less maintenance and repairs.

Disadvantages:
1. Large size and weight: Compared to some other types of compressors, screw compressors are large in size and weight. This can present some challenges with installation and space requirements.

2. High initial cost: The initial cost of a screw compressor is usually high due to its complicated structure and manufacturing process. In the long run, however, its high-efficiency capabilities can lead to savings in operating costs.

3. Part load efficiency: The efficiency of screw compressors may decrease at part load conditions. Under low or varying load conditions, supplementary measures may be required to improve efficiency.

It is important to note that advantages and disadvantages will vary depending on the specific application and conditions of use. When choosing a compressor, factors such as actual needs, performance requirements, and cost-effectiveness should be considered comprehensively, and detailed consultation with manufacturers or professionals should be conducted.

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.
