Catalogy：Air Cooled Chillers
Determine the right cooling capacity for your setup by estimating kilowatt requirements per hour. 🤓
Basic Working Principle of Chillers
Chillers operate on a refrigerant cycle to provide efficient cooling by extracting heat from designated areas. This cycle involves four main stages:
Compression
Condensation
Expansion
Evaporation
This process enables chillers to provide consistent cooling in various industrial and commercial applications by continuously removing heat from the environment.
What Are Scroll and Piston Type Chillers?
Scroll and piston-type chillers are two specific air-cooled chillers with distinct compressor designs, each offering unique benefits for different cooling requirements.
Scroll compressors use a spiral scroll mechanism to achieve smooth and quiet refrigerant compression, making them ideal for environments where low noise is essential. Here’s how they work:
•The compressor consists of a fixed scroll and a moving scroll that rotates within it, gradually compressing the refrigerant to high pressure.
•This design eliminates intense mechanical contact, reducing noise and vibration.
•Ideal Applications: Scroll compressors are well-suited for office buildings, hotels, and public spaces where a quiet, stable cooling system is preferred.
Piston compressors, also known as reciprocating compressors, rely on a piston-driven mechanism that creates high-pressure cooling, making them ideal for demanding cooling applications. Here’s their operation:
•The piston compressor uses pistons within cylinders, similar to an engine, to compress refrigerant with strong force.
•This design allows for high compression ratios, delivering more powerful cooling for intensive applications.
•Ideal Applications: Piston compressors are commonly used in industrial settings, laboratories, and manufacturing plants, where high cooling power is essential.
Key Differences Between Scroll and Piston Compressors
•Noise Level: Scroll compressors offer quieter operation and are suitable for noise-sensitive environments.
•Cooling Power: Piston compressors provide higher cooling capacity and pressure, making them ideal for industrial applications requiring intensive cooling.
Comparison with Other Types of Air-Cooled Chillers
Different air-cooled chillers—like Scroll, Piston, Screw, Low Temperature, Dual-Use, PCB, and Oil Cooling—offer specific cooling advantages.

Cooling Requirements
Cooling Capacity Needs
Determining the correct cooling capacity is crucial for ensuring optimal performance and energy efficiency. Cooling capacity requirements vary depending on factors such as heat load, desired temperature, and application size. To help you make the right choice, we’ve included a simple calculation table on this page. This tool helps estimate the cooling load (in kW or TR) needed for your specific setup, guiding you toward the ideal chiller model to meet your cooling demands efficiently.
| Step | Description |
|---|---|
| 1. Determine the Heat Load | Assess the total heat produced by your equipment or process. This can often be found in equipment specifications. |
| 2. Apply Cooling Formulas | Use formulas or industry calculators to convert heat load into cooling capacity, factoring in the desired temperature drop and area size. |
| 3. Choose Based on Capacity | Once the required kW or TR is determined, choose a chiller with sufficient capacity to handle your cooling load effectively. |
Scroll and Piston Type Chillers are versatile and can meet a range of cooling demands. For moderate to high cooling needs in standard temperature applications, these chillers provide reliable, energy-efficient performance.

Environmental Temperature Impact
Environmental conditions play a significant role in chiller performance. High or low ambient temperatures can impact efficiency, particularly if the chiller is exposed to extreme weather conditions. Scroll and Piston Type Chillers are built to perform well across a range of environments; however, in hotter climates, additional cooling capacity might be necessary to counteract the increased heat load. Understanding your operational environment helps in selecting a model that will perform reliably under specific temperature conditions, ensuring stable operation regardless of external temperatures.
| Factor | Impact | Considerations |
|---|---|---|
| Operating Efficiency | Chillers perform best within a specified ambient temperature range (e.g., air-cooled chillers at ≤35°C). Efficiency decreases if ambient temperatures exceed this range. | For ambient temperatures above 43°C, the chiller may enter overload, triggering a shutdown due to high condenser pressure and exhaust temperature. |
| Cooling Capacity Fluctuations | Cooling capacity decreases as ambient temperature rises due to increased condenser pressure. Evaporator pressure remains unchanged, reducing cooling efficiency. | Higher outlet temperatures can temporarily boost cooling capacity, but also increase energy consumption. Maintain appropriate outlet temperature in hot conditions. |
| Equipment Protection | High ambient temperatures can cause compressors to intake overheated vapor, potentially leading to equipment failure. | Modern chillers often include overheat protection systems that shut down the equipment under unsuitable conditions to prevent damage. |
| Maintenance Needs | Frequent maintenance may be required in high-temperature environments to ensure efficient operation. | Regularly clean condensers and check system pressure to sustain performance and prevent overheating. |
| Equipment Selection | Chillers need to be selected based on their design operating range, ensuring compatibility with expected environmental conditions. | Select a model rated for high temperatures if necessary, and place air-cooled chillers in ventilated areas away from direct sunlight or other heat sources. |

Energy Consumption and Cost-Effectiveness
Energy Efficiency of the Chiller
Compressor Efficiency
Scroll and Piston Type Chillers are designed with energy-efficient compressors, helping to lower power usage during operation. Scroll compressors are known for their quiet, steady operation and efficient energy use, making them suitable for environments where consistent, moderate cooling is required. Piston compressors, on the other hand, offer strong cooling power, balancing efficiency with higher capacity for heavy-duty cooling needs.
Seasonal Efficiency
The energy performance of a chiller can vary depending on environmental factors like temperature and humidity. For regions with extreme seasonal temperatures, consider choosing a chiller with a higher seasonal energy efficiency ratio (SEER), which ensures optimal performance year-round.
Variable Capacity Options
Some chillers offer variable-speed compressors, which allow for adjusting cooling capacity based on demand. This feature can help reduce energy consumption when full capacity isn’t needed, providing flexibility and saving on electricity costs over time.
Balancing Initial Investment and Operational Costs
Investing in the right chiller involves considering both the initial purchase cost and the long-term operational expenses:
Upfront Investment
While high-efficiency chillers may come with a higher initial price, their reduced energy consumption can significantly lower monthly electricity costs, offering a faster return on investment.
Maintenance Costs
Routine maintenance helps avoid costly repairs and keeps the chiller running at peak efficiency. Energy-efficient models often require less frequent servicing, which can save on maintenance expenses over time.
Long-Term Savings
Opting for an energy-efficient chiller can result in substantial long-term savings, especially in high-demand settings. This cost-saving advantage can make up for any upfront investment, providing both operational and financial benefits.
