Product Description

60HP 50Ton process cooling chillers screw types of industrial cooling water systems 

A screw type air-cooled chiller is a type of refrigeration system used to cool a fluid (usually water or a glycol-water mixture) in various industrial and commercial applications. It is called a "screw" chiller because it utilizes a pair of rotating screws (typically helical rotors) to compress and circulate the refrigerant.

Here's how a screw type air-cooled chiller typically works:

1. Evaporator: The chilled fluid (water or glycol-water mixture) enters the evaporator, which is a heat exchanger. As the fluid flows through the evaporator, it absorbs heat from the process or equipment it is cooling.

2. Compressor: The low-pressure refrigerant gas, usually a mixture of refrigerants such as R134a or R410a, enters the compressor. Inside the compressor, the rotating screws compress the refrigerant, increasing its pressure and temperature.

3. Condenser: The high-pressure and high-temperature refrigerant gas then flows into the condenser, which is another heat exchanger. In the condenser, ambient air is blown over the condenser coils, dissipating heat from the refrigerant and causing it to condense back into a liquid state.

4. Expansion Valve: The condensed refrigerant passes through an expansion valve, which reduces its pressure and temperature. This leads to a rapid cooling effect, preparing the refrigerant for the evaporator.

5. Evaporator (again): The cycle repeats as the cold refrigerant flows back to the evaporator, ready to absorb more heat and continue the cooling process.

Screw type air-cooled chillers are known for their high cooling capacities, energy efficiency, and reliability. They are commonly used in applications that require large amounts of cooling, such as industrial processes, data centers, commercial buildings, and air conditioning for large spaces.

The "air-cooled" aspect refers to the fact that these chillers use ambient air to dissipate heat from the condenser coils, eliminating the need for a separate water cooling system or cooling tower. This makes them easier to install and maintain compared to water-cooled chillers, which require a separate water source and cooling tower infrastructure.

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.
