Purchasing Energy-Efficient Water-Cooled Electric Chillers

Performance Column

Annual Energy Use: Assumed 2,000 operating hours per year for 23 years.

View Details

Annual Energy Cost: Calculated based on an assumed electricity price of 8.6¢/kWh, which is the average electricity price at federal facilities in the United States.

Lifetime Energy Cost: Future electricity price trends and a 3% discount rate are from the Annual Supplement to NIST Handbook 135 and NBS Special Publication 709, Energy Price Indices and Discount Factors for Life Cycle Cost Analysis –  (NISTIR 85--37 update 1).

Lifetime Energy Cost Savings: The difference between the lifetime energy cost of the less efficient model and the lifetime energy cost of the required model or best available model.

Best Available Model Column

Calculated based on highest efficiency model identified in publicly provided manufacturer data as of June . More efficient models may be introduced to the market after FEMP's acquisition guidance is posted.

Required Model Column

Calculated based on FEMP-designated efficiency requirements. Federal agencies must purchase products that meet or exceed FEMP-designated efficiency levels.

Less Efficient Model Column

Calculated based on median efficiency of models identified in publicly provided manufacturer data as of June .

Products meeting FEMP-designated efficiency requirements may not be life cycle cost-effective in certain low-use applications or in locations with very low rates for electricity or natural gas. However, for most applications, purchasers will find that energy-efficient products have the lowest life cycle cost.

Agencies may claim an exception to federal purchasing requirements through a written finding that no ENERGY STAR-qualified or FEMP-designated product is available to meet functional requirements, or that no such product is life cycle cost-effective for the specific application.

What Are the Cooling Requirements for Your Facility?

Understanding your facility’s cooling requirements is the first step to choosing the right chiller. Factors such as the size of your space, the heat load, and the nature of your operations all impact the specifications you need. A manufacturing facility might require high-capacity cooling to manage equipment heat, while a smaller office might need a compact solution.

Evolution Cooling’s team excels at assessing these needs, ensuring you select a chiller with the right capacity and configuration. Our tailored recommendations account for operational demands, ensuring maximum efficiency and minimal downtime. Whether you’re upgrading an outdated system or installing a new one, aligning your choice with your cooling demands ensures optimal performance and long-term reliability.

What Are the Different Types of Chillers Available?

Chillers are classified into various types, each tailored to specific applications and operational needs. Air-cooled chillers are a popular choice for smaller facilities or locations where water resources are limited, as they rely on ambient air to dissipate heat. These systems are easier to install and maintain, making them suitable for buildings with space constraints or lower cooling demands. However, they can be less efficient in hot climates, where ambient temperatures challenge heat exchange. Water-cooled chillers, on the other hand, are designed for larger installations requiring high-efficiency cooling. These systems use a water source, such as a cooling tower, to manage heat more effectively, offering superior performance even in demanding environments. 

Other types include evaporative chillers, which combine air and water cooling for enhanced efficiency, and hybrid systems that adapt to fluctuating demands. Selecting the right chiller depends on factors such as facility size, energy goals, and environmental conditions. A thorough evaluation ensures a solution that balances operational needs with cost efficiency. At Evolution Cooling, we can provide guidance on the best option for your needs, offering an extensive range of models to fit any facility. 

How Does Energy Efficiency Impact Chiller Performance and Costs?

Energy efficiency is a critical consideration when purchasing a chiller. Choosing an energy-efficient model reduces operational costs and aligns with sustainability goals. Look for chillers with a high SEER (Seasonal Energy Efficiency Ratio) rating or advanced features, such as variable speed drives, to improve performance. 

Please note that Evolution Cooling prioritises efficiency, offering a selection of chillers that not only reduce energy consumption but also enhance long-term savings. Our expertise ensures that you select a chiller designed to meet your energy requirements while keeping utility bills manageable. With the right model, you can achieve both peak performance and cost-effectiveness, ensuring your investment pays off over time.

How Important Is Maintenance and Servicing for Chiller Longevity?

Routine maintenance is vital for keeping a chiller functioning efficiently and extending its lifespan. Without regular servicing, chillers are more prone to reduced performance, higher energy consumption, and unexpected breakdowns, which can be costly to repair. Proper maintenance involves inspecting key components such as compressors, condensers, and evaporators, as well as monitoring refrigerant levels and cleaning filters. Addressing minor issues early prevents them from escalating into significant problems that disrupt operations. Regular maintenance also improves energy efficiency, ensuring the system runs optimally and lowers operational costs over time.

We help to minimise these risks by providing thorough maintenance services, including routine inspections and prompt repairs. With quick access to replacement parts and expert servicing, operational downtime is kept to a minimum, enhancing both the reliability and longevity of the equipment.

What Should You Know About Initial Costs Versus Lifetime Costs?

When buying a new chiller, balancing initial costs with lifetime costs is crucial. While cheaper models may seem attractive, they often come with higher operational expenses due to inefficiency or frequent repairs. 

Our energy-efficient chillers and tailored maintenance plans reduce overall costs, making them a sound investment. By focusing on both upfront affordability and ongoing savings, we will ensure that your chosen system provides maximum return on investment over its operational life. This factor alone makes us the ideal choice for businesses prioritising cost-effectiveness and reliability.

Factors When Buying a New Chiller Unit in Summary

Choosing a new chiller involves balancing technical and practical requirements. By thoroughly assessing your facility’s needs and the options available, you can ensure optimal performance and cost-effectiveness. With expert guidance and comprehensive solutions, Evolution Cooling makes it easier to find the perfect chiller unit tailored to your goals.
