Product Description
JLSW-120D Water Cooled Screw Chiller High Refrigeration Efficiency, Good Stability, Low Noise And High Reliability
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 machine is a commonly used refrigeration equipment with the following characteristics:
1.High efficiency and energy saving: The water-cooled screw machine adopts twin-screw compressors, which has the characteristics of high efficiency and energy saving. Twin-screw compressors have higher refrigeration efficiency and lower energy consumption than traditional single-screw compressors.
2.Stable and reliable: The operation of the water-cooled screw machine is stable and reliable, and has the characteristics of long life. Its structure is simple, maintenance is convenient, and it can meet the needs of different users.
3.Controllable energy consumption: The water-cooled screw machine can control energy consumption according to actual needs, and realize precise control through the control system, so as to achieve the purpose of energy saving.
4.Environmental protection and energy saving: The water-cooled screw machine adopts environmentally friendly refrigerants, which have low greenhouse effect and zero ozone layer destruction potential, and meet environmental protection requirements.
5.Wide range of application: The water-cooled screw machine has a wide range of applications and can be widely used in air conditioning, cold storage, industrial refrigeration and other fields.
6.Low noise: The noise of the water-cooled screw machine is low, which can meet the needs of noise-sensitive occasions.
7.Strong flexibility: The installation and use of water-cooled screw machines are very flexible, and can be customized and installed according to different places and equipment requirements.
In short, the water-cooled screw machine has the advantages of high efficiency and energy saving, stability and reliability, controllable energy consumption, environmental protection and energy saving, wide application range, low noise, and strong flexibility. It can meet the needs of different users and is a very practical 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.
