Product Description
Product Description:
Air-cooled screw chiller is a kind of industrial refrigeration and commercial air conditioning equipment, mainly composed of evaporator, compressor, condenser and expansion valve and other components. It uses a screw compressor to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gas, then releases heat to the outside through the condenser, and finally reduces the temperature and pressure of the refrigerant through the expansion valve to return to the evaporator for recycling.
During operation, the air-cooled screw chiller absorbs the heat in the outdoor air, cools the cooling water and circulates it to the room, so as to reduce the indoor temperature. Its cooling efficiency is greatly affected by factors such as outdoor temperature and humidity, so its effect may be limited in high-temperature and high-humidity environments.
Compared with water-cooled chillers, air-cooled screw chillers do not require an additional cooling water system, so they are simpler and more cost-effective. However, since it uses outside air for cooling, it can be problematic in areas with high air pollution or where indoor air quality needs to be maintained.
Production Features:
Air-cooled twin-screw chiller is a refrigeration equipment that uses air cooling to dissipate heat. It is mainly used to provide cooling water or coolant to reduce the temperature. It combines the advantages of air cooling technology and twin-screw compressors, and is efficient, reliable and energy-saving.
The following are some characteristics and working principles of air-cooled twin-screw chillers:
1. Efficient refrigeration: Air-cooled twin-screw chillers use twin-screw compressors and have efficient refrigeration capacity. Through the rotational motion of the screw, the refrigerant is compressed into high-pressure and high-temperature gas, and then the heat is dissipated through the condenser to convert the refrigerant into high-pressure liquid.
2. Air-cooled heat dissipation: Compared with the traditional water-cooling method, air-cooled twin-screw chillers use air cooling to dissipate heat. It uses a fan to blow air through the condenser to transfer the heat of the high-temperature refrigerant to the surrounding air, thereby achieving a heat dissipation effect. This heat dissipation method does not require additional cooling water or cooling towers, simplifying the installation and operation process.
3. Multiple capacity options: Air-cooled twin-screw chillers offer a variety of capacity options for applications of different sizes and needs. They can meet the cooling needs of various places from small commercial buildings to industrial plants.
4. Stable and reliable: The air-cooled twin-screw chiller has stable and reliable operating characteristics and can provide stable cooling effects under different load conditions. The design of its twin-screw compressor and air-cooled heat dissipation system makes it highly adaptable and able to cope with the requirements of different environments and working conditions.
5. Energy saving and environmental protection: The air-cooled twin-screw chiller adopts advanced refrigeration technology and energy-saving measures, with high energy efficiency ratio and energy-saving effect. They are usually equipped with advanced control systems, which can be intelligently adjusted and optimized according to actual needs, thereby reducing energy consumption and operating costs.
Air-cooled twin-screw chillers are widely used in the fields of air conditioning and industrial cooling. They combine the characteristics of efficient refrigeration, air-cooled heat dissipation and energy saving and environmental protection, providing users with reliable cooling solutions and have significant advantages in energy efficiency and environmental protection.
Working Principle:
The working principle of the air-cooled screw chiller is as follows:
Compression process: The refrigerant is compressed into a high-temperature and high-pressure gas in the screw compressor, and then enters the condenser.
Condensation process: The high-temperature and high-pressure gas is cooled in the condenser to become a high-pressure liquid, and at the same time release heat, which is dissipated into the outdoor air through fans and radiators.
Expansion process: After the high-pressure liquid is decompressed by the expansion valve, it becomes a low-temperature and low-pressure liquid, and then enters the evaporator.
Evaporation process: The low-temperature and low-pressure liquid evaporates in the evaporator, absorbs the heat in the room, cools down the cooling water in the room, and circulates it to the room, thereby achieving the purpose of reducing the indoor temperature.

Application Industry:
Chillers are widely used in the film production industry. Film production is a process of manufacturing film materials. Common applications include plastic film, metal film, glass film, etc. The following are the main applications of chillers in the film production industry:
1. Cooling extruder: During the extrusion process of film production, the extruder extrude the molten material into a film shape through the extruder head. The extruder usually generates a lot of heat and needs to be cooled by cooling water to maintain a suitable working temperature. The chiller reduces the temperature by providing cooling water circulation through the extruder to ensure the stability of the extrusion process and the quality of the film.
2. Cooling roller: During the coating and calendering process of the film, the cooling roller is used to quickly cool and solidify the film material. The chiller provides cooling water to reduce the temperature of the cooling roller, ensuring the rapid cooling and solidification of the film material to obtain the ideal surface quality and performance.
3. Cooling tower: The cooling tower is used in combination with the chiller to handle the temperature of the cooling water. In film production, the cooling tower uses the principle of evaporative cooling to reduce the temperature of the cooling water by spraying hot water into the air. The chiller circulates cooling water into the cooling tower to cool it and then supplies it again to the equipment that needs cooling during the film production process.
4. Temperature control: Various stages in the film production process, such as extrusion, coating, drying, etc., require precise temperature control. The chiller regulates the temperature in the equipment and process by providing cooling water or coolant to ensure the production quality and stability of the film material.
5. Environmental control: Film production requires specific ambient temperature and humidity conditions. The chiller is used in conjunction with the air conditioning system to provide constant temperature and humidity control for the production area to meet the temperature and environmental requirements during the film production process.
By using the chiller in these specific application scenarios in the film production process, precise temperature control, cooling and curing of film materials, and providing a suitable production environment can be achieved. These applications help improve production efficiency, optimize product quality, and meet the temperature and environmental requirements during the film production process.
