Chiller Efficiency Tips to Achieve Seasonal Efficiency Year Round

Commercial chiller systems are the backbone of keeping large spaces cool and comfortable, but running them efficiently can be challenging, especially with fluctuating seasonal demands. The good news? By making small adjustments throughout the year, you can maximize chiller efficiency, reduce energy consumption, and extend the lifespan of your equipment. Ready to learn how to optimize your chiller’s performance each season?

Seasonal Energy Efficiency Tips for Commercial Chiller Systems

Managing the energy efficiency of your commercial chiller systems is essential for controlling operating costs and ensuring peak performance. Each season presents unique challenges, making it important to adjust how your chillers operate as the temperatures fluctuate throughout the year. Whether you’re facing the sweltering heat of summer or the cold snap of winter, optimizing chiller efficiency requires a proactive approach.

Let’s break down actionable tips for managing your commercial chiller systems throughout the seasons, reducing energy consumption while keeping your building comfortable.

Spring: Prepare for Rising Temperatures

Preparing your chiller system for increased demand is essential as the weather starts to warm up in the spring. Since cooling loads typically rise during the warmer months, spring is the perfect time to evaluate your system’s efficiency and plan for necessary maintenance.

Here’s what to focus on:

Schedule a comprehensive chiller service – Have your system thoroughly inspected by a professional technician to ensure all components are in top working order. Spring is an ideal time to identify and fix any small issues before they escalate into costly breakdowns.
Clean the condenser coils – Dirty condenser coils make your chiller work harder, reducing efficiency. Regularly cleaning these coils in the spring helps prepare the system for the increased workload as temperatures rise.
Check refrigerant levels—Low refrigerant levels can drastically reduce your chiller’s cooling capacity and efficiency. To avoid performance issues, a spring tune-up should include verifying that the refrigerant levels are correct.

Summer: Maximize Cooling Efficiency

When summer hits, your chiller will likely be operating at full capacity to meet cooling demands. This season requires special attention to maintain chiller efficiency and keep energy costs in check.

Summer tips to boost chiller efficiency:

Optimize setpoints—Adjusting the chiller’s setpoint to the highest possible temperature while maintaining comfort is one of the easiest ways to reduce energy usage. Every degree of temperature change can save significant energy over time.
Use cooling towers efficiently – Pairing your chiller with an optimized cooling tower can improve efficiency. By lowering the entering condenser water temperature, your chiller won’t have to work as hard, improving overall performance.
Regularly check water quality – Poor water quality in the condenser loop can lead to fouling, which reduces heat exchange efficiency. Routine water treatment during summer can help prevent energy losses caused by corrosion or mineral buildup.

Fall: Transition to Lower Loads

As temperatures begin to cool, the load on your chiller system decreases. This shift offers a prime opportunity to make adjustments that conserve energy and ensure your system is ready for the cooler months ahead.

Here’s how to adjust your chiller operations in the fall:

Reduce cooling capacity – Since your building likely won’t need as much cooling, consider reducing the chiller’s capacity. This will prevent the system from short-cycling, which can waste energy and wear out components.
Check for insulation issues – Inspect your system for any insulation problems as the weather changes. Proper insulation keeps chilled water lines efficient and prevents unnecessary energy loss.
Begin prepping for winter – Fall is the perfect time to start planning for colder weather. Perform any necessary preventive maintenance to ensure your chiller system can handle the transition smoothly.

Winter: Prioritize Energy Savings

Cooling loads tend to drop significantly during the winter. Many businesses can rely on lower-capacity chiller operations or temporarily turn off their systems. However, proper care during this season is still important to maintaining efficiency and extending the lifespan of your chiller system.

Winter efficiency tips:

Use economizers when possible. Economizers allow you to cool your building using cold outdoor air without relying on mechanical cooling. This free cooling method can drastically reduce your energy use in the winter.
Turn off unnecessary chillers – If your cooling load is low enough, consider shutting down some of your chillers entirely. This reduces wear and tear on the system and saves energy.
Conduct off-season maintenance – Winter is an ideal time for performing more in-depth maintenance tasks that may be harder to schedule during peak cooling months. This includes replacing worn parts and cleaning the system for optimal performance.
