Jiujiang Outdoor Equipment Pilot: 13°C Temperature Reduction and 30% AC Energy Saving with Aerogel Coating

To address frequent high-temperature alarms in outdoor color steel rooms, multi-compartment cabinets, and battery swapping cabinets during Jiujiang's peak summer temperatures of 26-38°C, 2mm aerogel thermal insulation coating was applied to equipment exteriors, with unmodified units maintained as controls for direct temperature and energy consumption comparison.Outdoor equipment in Jiujiang's climate faces intense solar heat gain during summer operation, causing interior temperatures to exceed safe thresholds and triggering high-temperature alarms that disrupt service continuity. Active cooling through air conditioning addresses the symptom but increases energy consumption and operating costs significantly. A passive insulation solution that reduces heat gain at the source would reduce both alarm frequency and the energy burden placed on active cooling systems.Results from the controlled comparison demonstrated a maximum surface temperature difference of 13°C between coated and uncoated equipment, with coated units effectively blocking solar heat gain through exterior surfaces. Internal temperatures of coated equipment remained stable below 35°C throughout monitoring, eliminating the high-temperature alarms that consistently affected uncoated control units under identical conditions.Beyond temperature control, air conditioning energy consumption for coated equipment dropped by approximately 30% compared to uncoated controls, directly reducing operating costs. The payback period for two-compartment cabinet coating applications was calculated at less than 12 months based on energy savings alone, establishing a strong economic case for aerogel coating adoption across outdoor equipment installations in high-temperature summer climates. This Jiujiang pilot validates AG-C aerogel coating as both a reliable thermal performance solution and a cost-effective operational investment for outdoor telecommunications and energy infrastructure.
