Running a facility efficiently is no easy feat. You may have invested in top-of-the-line cooling equipment with low kW consumption and a five-star efficiency rating, but does that necessarily mean you’re operating at peak energy efficiency? Your HVAC system, often the biggest contributor to operational expenses, also holds the most potential for savings if managed correctly. Here’s our guide to help you unlock the hidden potential of your HVAC system and enjoy up to 30% energy savings.
1. Rethink Ventilation Fan Usage
Ventilation fans typically have low kW ratings, but do they really need to run 100% of the time? A need-based switching mechanism can help you operate them only when required, reducing unnecessary energy consumption.
2. Monitor AHU Performance
- Operational TR vs Actual Capacity: Regularly compare the operational tonnage of refrigeration (TR) with the actual capacity of the Air Handling Unit (AHU) to ensure you’re not overworking or underutilising the system.
- Actuator and Valve Operations: Check whether the actuator and valves are functioning as intended. Inefficiencies here could lead to energy wastage.
- Filter Maintenance: Establish a schedule for filter replacement. Clogged filters not only affect air quality but also force the system to work harder.
- Fan Efficiency: Verify if the AHU fan is delivering the stipulated cubic feet per minute (CFM) of air volume. Low performance might indicate the need for maintenance.
3. Optimise Chilled Water Pumps
Assess whether your chilled water pumps are delivering the required flow rate (m³/hr). Regularly inspect and clean strainers to maintain pump efficiency and avoid unnecessary energy consumption.
4. Chiller Maintenance
- Descaling Activities: Plan descaling for the condenser or evaporator sections based on performance indicators rather than a fixed schedule.
- Identify Inefficiencies: Determine which section—the evaporator or condenser—is contributing to inefficiency and address the issue specifically.
- Check Refrigerant Levels: Ensure refrigerant levels are sufficient to maintain optimal suction and discharge pressures.
- Temperature Management: Monitor the chilled water in and out temperatures during normal operations. You may see significant savings by increasing the chilled water set point when feasible.
- Assess Kw/TR Performance: Compare your chiller’s kW per ton of refrigeration with industry benchmarks to ensure you’re hitting the best operating point.
