Product Description

50Ton -100Ton large capacity Industrial cooling air cooled screw chiller for industrial application
How Air cooled screw chiller works ?

An air-cooled screw chiller is a type industrial water chiller that utilizes a screw compressor to cool the process water. Here's how it works:

1. Compressor: The heart of the chiller is the screw compressor. It consists of two interlocking rotors (usually helical) that compress the refrigerant gas. As the rotors rotate, they reduce the volume of the gas, increasing its pressure and temperature.

2. Refrigerant circulation: The compressed gas is then sent to the condenser, where it releases heat and rejects it to the ambient air. The high-pressure, high-temperature refrigerant gas condenses into a high-pressure liquid.

3. Condenser: In an air-cooled screw chiller, the condenser is cooled by ambient air. It typically contains a series of finned tubes through which the refrigerant flows. Fans blow the ambient air across these tubes, extracting heat from the refrigerant and cooling it down. As a result, the refrigerant condenses into a high-pressure liquid.

4. Expansion valve: The high-pressure liquid refrigerant then passes through an expansion valve, which reduces its pressure and temperature. This conversion from high pressure to low pressure causes the refrigerant to expand and evaporate.

5. Evaporator: The low-pressure refrigerant enters the evaporator, which is the heat exchanger where the process water flows. The refrigerant absorbs heat from the process water, causing it to evaporate and turn into a low-pressure gas.

6. Compressor and cycle: The low-pressure gas returns to the screw compressor to be compressed again, restarting the cycle. The process water, now cooled, is then circulated back to the plastic extrusion machine or any other industrial process that requires cooling.

7. Air-cooled condenser fans: Air-cooled screw chillers have one or more condenser fans that draw ambient air over the condenser coils to facilitate heat transfer. These fans are usually driven by electric motors and can be variable speed or fixed speed, depending on the cooling requirements.

Overall, air-cooled screw chillers are self-contained units that use the ambient air to remove heat from the refrigerant, making them suitable for applications where water availability or cost is a concern. They are commonly used in industrial processes such as plastic extrusion, injection molding, chemical manufacturing, and HVAC applications.

An air cooled screw chiller is a type of refrigeration system used for cooling applications. It uses a screw compressor as the main component to circulate the refrigerant and remove heat from the system. Unlike water cooled chillers that require a separate cooling water source, air cooled screw chillers use ambient air as the cooling medium.

The application of air cooled screw chillers is wide-ranging and can be found in various industries and processes, including:

1. Commercial Buildings: Air cooled screw chillers are commonly used in office buildings, hotels, shopping malls, and other commercial facilities for air conditioning and HVAC (Heating, Ventilation, and Air Conditioning) applications.

2. Industrial Processes: They are utilized in industrial processes that require cooling, such as plastic manufacturing, rubber processing, metalworking, pharmaceutical production, food and beverage processing, and chemical manufacturing.

3. Data Centers: Air cooled screw chillers can provide cooling for data centers to maintain optimal temperatures for servers and sensitive electronic equipment.

4. Power Plants: They may be used for cooling in power generation plants, specifically for cooling turbine generator units and other equipment.

5. Hospitals: Air cooled screw chillers play a crucial role in providing cooling for critical areas in hospitals, such as operating rooms, laboratories, and medical equipment rooms.

6. Event Venues: They are frequently employed in convention centers, concert halls, and stadiums to maintain comfortable temperature conditions for large gatherings.

Air cooled screw chillers offer advantages such as simplified installation (no need for a separate cooling tower or water source), reduced water consumption, flexibility in installation locations, and ease of maintenance. However, they generally have slightly lower cooling capacity compared to water cooled chillers and may be affected by ambient temperature and air quality.
