Chart: Efficiency Comparison

Water-Cooled Screw Chiller Efficiency

• Higher Energy Efficiency (EER/COP): Generally, water-cooled screw chillers boast significantly higher energy efficiency ratios (EER) or coefficients of performance (COP) compared to air-cooled counterparts. This is because water is a much more efficient medium for heat transfer than air. This leads to lower operating costs.
• More Stable Performance: Water-cooled chillers tend to have more stable performance, especially in hotter ambient conditions, because their condenser is cooled by a relatively constant water supply (often from a cooling tower). This means less variation in performance and energy consumption.
• Lower Condensing Temperatures: They typically operate with lower condensing temperatures due to the efficient heat rejection to the water. Lower condensing temperatures directly translate to better chiller efficiency.
• Lower Compression Ratio: The ability to maintain lower condensing temperatures results in a lower compression ratio on the compressor which can extend the life of the compressor
• Part-Load Efficiency: Water-cooled chillers often maintain better efficiency at part-load conditions, meaning they are more efficient when not running at full capacity. This is important since chillers often operate at part load during certain times.
• Less Affected by Ambient Air Temperature: Water-cooled chillers are largely unaffected by fluctuations in ambient air temperatures, which contributes to their more stable and consistent performance.

Air-Cooled Screw Chiller Efficiency

• Lower Energy Efficiency (EER/COP): Generally, air-cooled chillers have lower energy efficiency ratios (EER) or coefficients of performance (COP) compared to water-cooled chillers. The lower heat transfer coefficient of air compared to water makes this the primary reason for the lower efficiency.
• Performance Affected by Ambient Conditions: Air-cooled chiller performance is strongly impacted by ambient air temperature. On hot days, their efficiency drops considerably. This can lead to higher energy consumption and sometimes reduced cooling capacity.
• Higher Condensing Temperatures: They typically operate with higher condensing temperatures because of the less efficient heat rejection to air.
• Higher Compression Ratio: As a result of higher condensing temperatures they also experience higher compressor ratios which can reduce the life of the compressor
• Part-Load Efficiency: Air-cooled chillers can be less efficient at part-load conditions, especially if they rely on simpler control strategies.
• Potential for Higher Noise Levels: Air-cooled chillers often use fans to move air across the condenser which can create higher levels of noise
• Simple Installation: Air-cooled chillers are typically easier to install because they don’t require a cooling tower or associated piping, simplifying the system and reducing costs.
• Less Water Consumption: This is a significant advantage in water-scarce regions. They do not require water for heat rejection and therefore don’t contribute to water consumption
• Lower Initial Cost is often associated with centrifugal chillers compared to water-cooled systems. The cost of an air-cooled chiller alone is often less than a water-cooled chiller because you don’t need the cooling tower or condenser water piping
• More Flexibility in Placement: Because they do not require a cooling tower and water pipe network they can be placed in more locations such as on a roof of a building

Which is Better?

The “better” choice depends on your specific needs and priorities:

• Choose water-cooled if:
  • You prioritize energy efficiency and lower operating costs, especially over the long term.
  • You have access to a reliable water source and have the space for a cooling tower.
  • Your application requires consistent cooling performance regardless of ambient conditions.
  • Noise is an issue and you have the available space for a cooling tower.
• Choose air-cooled if:
  • Water conservation is a priority.
  • You want a simpler and less expensive installation.
  • Your cooling needs don’t demand the absolute highest energy efficiency.
  • You have constraints on space and/or the ability to use a cooling tower.

Important Considerations:

• Climate: In hot, dry climates, water-cooled systems can be significantly more efficient and cost-effective, despite requiring a cooling tower. However, they may require increased maintenance. Air-cooled systems will have to work harder and be less efficient in high-heat climates
• Life-Cycle Cost: While air-cooled chillers may have lower initial costs, the higher energy consumption over the life of the chiller may make a water-cooled system more economical in the long run.
• Local Regulations: Water usage restrictions and local building codes may affect your decision.
• Mantenimiento: Cooling towers for water-cooled systems require additional maintenance. Air cooled chillers are easier to maintain since the primary components are only the chiller itself. Typical Performance Ranges for 100 HP Screw Chillers Feature 100 HP Water-Cooled Screw Chiller (Typical) 100 HP Air-Cooled Screw Chiller (Typical) Cooling Capacity (BTU/hr) ~1,200,000 – 1,500,000 ~1,000,000 – 1,300,000 Energy Efficiency Ratio (EER) 10 – 14 (Typically 11-12 under ARI conditions) 8 – 11 (Typically 9-10 under ARI conditions) Coefficient of Performance (COP) 2.9 – 4.1 2.3 – 3.2 Full Load Power Input (kW) ~85 – 95 kW ~95-110 kW Part-Load Efficiency Good, often maintains high EER/COP Lower, can drop significantly at part loads Condensing Temperature ~85-95°F ~110-120°F (and higher in high ambients) Water Consumption Higher (for cooling tower) None Approximate Initial Cost $60,000 – $80,000 (Chiller + Tower) $40,000 – $60,000 (Chiller only) Maintenance Costs Higher (includes cooling tower) Lower
  • EER = BTU/hr / Watts input
  • COP = kW cooling output / kW electrical input
  • These values are representative and can vary greatly
  Detailed Comparison at 100 HP:
  • Energy Efficiency (EER/COP):
    • Water-Cooled: As seen in the ranges above, a 100 HP water-cooled screw chiller will typically have an EER in the range of 10 to 14, and a COP between 2.9 and 4.1. The average energy efficiency of water-cooled chillers can be 20-30% higher than air-cooled chillers in the 100 HP range. This means they use significantly less electricity to produce the same amount of cooling.
    • Air-Cooled: A 100 HP air-cooled screw chiller will typically operate with an EER in the range of 8 to 11, and a COP between 2.3 and 3.2. The values of the efficiency will vary based on ambient temperature.
  • Power Consumption:
    • For the same cooling output, the water-cooled chiller will generally draw less power. In the examples shown above the water cooled unit will generally operate between 85 -95 kW at full load whereas the air cooled unit will usually operate between 95-110kW.
  • Condensing Temperature:
    • Water-Cooled: Condensing temperatures are typically much lower, in the 85 to 95°F range, which contributes to the better efficiency.
    • Air-Cooled: They often have much higher condensing temperatures often in the 110-120°F range or higher, especially on hot days, negatively impacting efficiency.
  • Part-Load Performance:
    • Water-Cooled: Often maintain good efficiency at partial load, as the cooling tower water temperature is relatively constant
    • Air-Cooled: Efficiency can drop significantly at part-load conditions as the unit’s ability to reject heat is dependent on ambient air.
  • Impact of Ambient Temperature:
    • Water-Cooled: Relatively unaffected by ambient air temperature, providing consistent cooling output.
    • Air-Cooled: Performance will degrade as ambient temperatures rise, potentially requiring the unit to operate for longer periods or to a reduced capacity to meet the cooling load.
  • Water Consumption:
    • Water-Cooled: Requires significant water consumption for the cooling tower.
    • Air-Cooled: Uses no water.
  • Initial Costs:
    • Water-Cooled: Initial cost, when considering the chiller and cooling tower costs, is usually higher than an air-cooled chiller of the same capacity.
    • Air-Cooled: Less expensive in terms of the initial investment as it does not require a cooling tower.
  • Instalación:
    • Water-Cooled: More complex installation process
    • Air-Cooled: Simpler installation process
  Practical Example: Let’s consider two hypothetical scenarios for a 100 HP chiller used for approximately 2000 operating hours per year in a moderate climate:
  • Water-Cooled:
    • Average EER: 12
    • Average Power Input: 88 kW
    • Annual Energy Consumption: 88 kW * 2000 hrs = 176,000 kWh
  • Air-Cooled:
    • Average EER: 9.5
    • Average Power Input: 105 kW
    • Annual Energy Consumption: 105 kW * 2000 hrs = 210,000 kWh
  In this scenario, the water-cooled chiller would consume significantly less energy over the year compared to the air-cooled unit. Key Takeaways (100 HP Focus):
  • A 100 HP water-cooled screw chiller will generally provide higher EER/COP values compared to an air-cooled counterpart of the same nominal size.
  • Water-cooled systems consume less energy and provide more stable performance, however, at a higher initial cost, due to the need for a cooling tower.
  • The choice of 100 HP air-cooled screw chillers is attractive for smaller installations where the initial cost or water constraints are primary considerations, but it is generally less energy efficient.
  Recommendation: For a 100 HP application, a water-cooled chiller will very often be more energy efficient in the long run and offer more stable operation, however, this will come at a higher initial cost. An air-cooled chiller might be considered if initial costs or water usage is paramount. Always look at the full lifecycle cost analysis before making a final decision. It is also best practice to consult with a qualified HVAC engineer for the best system design.

Conclusion:

Water-cooled screw chillers generally offer higher energy efficiency and more stable performance but require more complex infrastructure (cooling towers). Air-cooled screw chillers are simpler, more flexible in placement, use less water, and have lower initial costs, but are less energy efficient and performance can fluctuate in relation to ambient temperature. The “best” choice will depend on careful consideration of your specific circumstances and priorities. It is important to do a full life-cycle cost analysis to determine the best solution for your needs.
