An air-cooled chiller uses ambient air to dissipate heat from the refrigerant circuit. Therefore, it does not require a water cooling system or tower on-site. The chiller condenser is typically a finned coil integrated with a fan to circulate the air. 60kw air-cooled chillers can be either packaged or split.
Air-cooled chillers also vary according to the compressor type. Compressed gas has the biggest market share. Reciprocating compressors work by taking in the chilled water or gas air and compressing it into a high-pressure state. It is widely used in industrial cooling due to its reliability and efficiency. Screw compressors work by using two interleaved screws to push the refrigerant gas. They are suitable for providing medium to high capacities. Scroll compressors are suitable for small to medium capacities. Centrifugal compressors use the centrifugal force generated by a rotor to compress the refrigerant. It is more suitable for large capacity cooling.
Cooling Capacity:
A 60kw air cooled chiller's cooling capacity has to be within the 60kw range. The majority of the machines will deliver the magnitude of cooling.
Compressor Type:
An air cooled chiller with a scroll compressor will weigh less and be more efficient. If the chiller uses a screw compressor, it will be large, heavy, and able to cool larger quantities.
Voltage:
A 60kw air cooled chiller will typically use 3-phase 380/400/415 AC (alternating current) power. The exact voltage will differ according to the local supply.
Refrigerant:
A refrigerant is a chemical that changes from gas to liquid and back again at room temperature. The chemical, such as GK-134a, is used to absorb heat from the water and cool it. The refrigerant will differ from one chiller to another.
Fan Size and Speed:
Generally, an air-cooled chiller depends on the external environment to dissipate heat and must do so at higher fan speeds. The fan design with larger blades moves more air at lower speeds, doing the job effectively and quietly.
Water Flow Rate:
Water flow through the system will be around 10.4 to 11.6 cubic meters per hour (m3/h) or 2,740 to 3,060 gallons per hour (gph) to remove that capacity of cooling.
A well-designed air-cooled chiller needs very little maintenance, but it is vital to do it to keep the system working well and avoid any accidents.
Regular inspection:
The machine should be inspected to check for any gas leaks in the system, and tests should be done as needed. The streamline of the refrigerant should be checked to ensure none of the moving parts are vibrating.
Fans and Coils:
The external cooling fins of the coils and the fans must be clear of heat and dirt, which affects performance. All debris needs to be removed, and the coil must be clean for air circulation to be adequate.
60kw air cooled chillers are used in a variety of industrial settings:
HVAC systems:
60kw air cooled chillers are major components of central air conditioning systems. They provide cooling for large areas in commercial buildings, shopping malls, hotels, etc. By working with air cooled condensers, they maintain indoor spaces comfortable.
Plastic injection molding:
Injection molding machines need to be kept at a constant temperature during the molding process in order to ensure product quality and consistency. Air-cooled chillers can do just that, making them a great choice for this application.
Process cooling:
Industries like food and beverage, chemical, pharmaceutical, and more often use air-cooled chillers for process cooling. They cool down equipment, reactors, tanks, and other devices. Also, they control temperatures of products, enabling smooth operations and quality control.
Data centers and server rooms:
Air-cooled chillers play a vital role in keeping the right temperature and humidity levels in places like computer warehouses and server storage. By doing their job well, these machines make sure that the hardware stays functional and operates perfectly.
Printing and dyeing:
Air-cooled chillers are commonly used in the printing and dyeing industry. They help cool printing presses, drying cylinders, and other equipment. Also, they maintain constant temperatures and prevent overheating. Therefore, the durability of machines is ensured and production efficiency is boosted.
Central chilled water systems:
Air cooled chillers can serve as a part of central chilled water systems. The central system produces chilled water which is then distributed to different end-users locations through a water loop. It allows for effective cooling to be provided to multiple buildings or processes from a single chiller.
Load requirements:
It is important to determine the cooling capacity and tonnage needed for the facility, which should match the 60kw air-cooled chiller to meet the load requirements.
Energy efficiency:
Consider selecting 60kw air-cooled chillers with higher EER and IPLV/UITPV to ensure an optimal performance level.
Noise level:
Consider choosing air-cooled chillers with lower noise levels. This can be achieved by selecting optimal refrigerant types and utilizing sound-attenuating materials for the chiller's casing and exhaust design.
Design and space:
Pay attention to the overall chiller dimensions. Ensure the machine can be appropriately and conveniently installed in any required space.
Operating environment:
Ensure that the 60kw air-cooled chiller can operate in an adequately maintained environment, with suitable resistance to potential hazards like moisture, dust, and chemicals.
Electrical supply:
Ensure that the air-cooled chiller's required voltage, phase, and frequency are compatible with the available electrical supply at the installation location.
Controls and integration:
Consider the control system capabilities of the air-cooled chiller, along with options for integration with building management systems (BMS) for centralized monitoring and control.
Regulatory compliance:
Ensure that the air-cooled chiller complies with relevant regulations and standards, including safety, environmental, and energy efficiency codes.
Logistics and installation:
Consider the logistics and installation process for the air-cooled chiller, including packaging, handling, and transportation options.
Service and support:
Choose an air-cooled chiller from a manufacturer that offers reliable service, support, and availability of replacement parts.
Q1: Are there any special considerations for the 60kw air cooled chillers when it comes to transportation?
A1: The main thing to consider is the size of the chillers. This means that the transport used will need plenty of space. It also gives enough cooling for any goods that need a chiller to be transported. Using pallets and packing boxes is a good idea as they are easier to stack and unpack.
Q2: Is it possible to customize a 60kw air cooled chiller?
A2: Many manufacturers will offer customization options for the chillers. This may include things like changing the color of the chiller to match a business's logo or branding. This will also include adding any extra features. Buyers can also request OEM services.
Q3: How long does a 60kw air cooled chiller last?
A3: With proper maintenance and care, the air chiller can last for about 10 to 15 years. The lifespan may be shorter or longer, depending on the quality of the chiller.
Q4: What is the difference between a KW and a ton chiller?
A4: A KW chiller is a measurement of the cooler's capacity based on heat exchange, while a ton measures how much ice a cooler can make in one day. As a result, there can be some discrepancies when converting tonnage to kilowatts. Generally speaking, 1 ton = 3.517 KW.
