Introduction

In certain climates, where cooling systems operate year-round, optimizing HVAC systems is crucial for energy savings and system efficiency. A renowned hotel sought a solution to improve its FAHUs' (Fresh Air Handling Units) performance, specifically targeting energy efficiency and cooling coil cleanliness. The innovative Fighter Flex (FF) UVC technology from Airocide Systems, combined with BATTA Technologies' expertise, was implemented following the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards.

Project Overview

• Objective: The hotel operates two mirrored rooftop FAHUs, running continuously due to the hot climate. The project aimed to compare the performance of a UVC-treated FAHU with an untreated control unit. Sensors were installed to monitor various performance metrics over 60 days.
• Scope: Install Fighter Flex UVC in one FAHU, leaving the other as a control. Measure and compare airflow, humidity, temperature, pressure differential, and energy efficiency gains.
• ASHRAE Guidelines: The test followed ASHRAE energy monitoring standards to ensure accurate data collection and verification of results.

Key Metrics & Results

• Air Velocity: Increased by 51% in the UVC-treated unit, indicating smoother airflow across the cooling coils.
• Humidity: Decreased by 8%, showing improved dehumidification efficiency in the UVC-treated system.
• Temperature After Coil: Dropped by 17%, or a 15°F reduction, which means the unit is cooling more efficiently.
• Pressure Drop: Reduced by 45%, indicating less resistance across the coil, lowering the energy demand on the fan motor.
• Energy Efficiency: The UVC treatment resulted in a 24.5% overall efficiency gain for the system.

Fighter Flex Technology: A Disruptive Solution

The Fighter Flex UVC technology targets and neutralizes biofilms, mold, and dirt buildup on cooling coils, improving airflow and heat exchange. As a result, the system requires less energy to maintain desired cooling levels, while also extending the lifespan of HVAC components. This represents a major shift in how facilities manage cooling efficiency and air quality.

Financial Impact & Quick ROI

• Cost savings: The test revealed significant reductions in energy consumption, leading to immediate operational savings.
• ROI: The return on investment was achieved in a remarkably short period due to the substantial efficiency improvements, making this technology a game-changer for large facilities with high cooling demands.

Conclusion

By employing Fighter Flex UVC technology, the hotel saw not only a 24.5% increase in energy efficiency, but also significant reductions in humidity and cooling coil fouling. This technology, when implemented following ASHRAE guidelines, delivers rapid returns on investment, marking it as a disruptive and highly effective solution in energy management.
