Deaoxi Inverter Cold-Storage Unit Delivers Over 30% Comprehensive Energy Saving
For cold-storage operators, electricity cost is always a top concern. Many purchasers worry that 24-hour continuous operation will result in staggering monthly power bills and question whether real energy-saving effects can be achieved with the fruit vegetable cold room refrigeration unit. Authentic user feedback provides straightforward answers to such concerns.
“As fruit wholesalers, we suffer most from high electricity costs and unstable storage temperature. After using Deaoxi cold-storage equipment, our electricity bills have improved greatly. Stable cold-room temperature has significantly cut fruit spoilage, making this equipment a worthwhile investment.” — Fruit wholesaler from Shijiazhuang.
“The old-style cold storage used to cost nearly 2,000 RMB per month for electricity. After switching to Deaoxi, we save almost half of our monthly power expense. The saved amount becomes pure net profit. Moreover, mobile remote monitoring enables convenient real-time operation checks, bringing much-appreciated peace of mind.” — Fruit wholesaler from Anhui Province.
Energy-saving performance of the high efficiency cold room refrigeration unit is driven by the synergy of two core technologies instead of a single technical upgrade. Traditional fixed-frequency cold-storage equipment works like a car without a gearbox, operating either at full speed or complete shutdown. Repeated start-stop cycles generate huge inrush surge current, which constitutes the primary cause of excessive power consumption. Deaoxi AI DC inverter technology changes this operating mode fundamentally. The compressor and DC direct-drive fan realize stepless speed regulation to precisely match load variation and achieve more than 30 % energy saving compared with conventional units. Instead of shutting down once target temperature is reached, the compressor smoothly shifts to medium-low-frequency operation calculated by the AI system. This solution greatly lowers operating noise, eliminates high energy loss from frequent restarts, reduces component abrasion and extends overall equipment service life.
Defrosting is another major power-hungry link for cold-storage systems. Conventional electric heating defrost converts electricity directly into heat for ice melting with merely around 30 % energy utilization rate, wasting roughly 70 % of input power. Deaoxi dual-phase-switch intelligent hot-gas rapid defrosting for indoor and outdoor units reuses inherent condensation heat within the refrigeration loop without extra energy input. Its energy utilization efficiency exceeds 70 %. Complete defrosting can be finished within approximately 3 minutes with thorough ice removal. Minimal temperature fluctuation inside cold rooms protects commodity quality, which is a key advantage of the intelligent temperature control cold room refrigeration unit. Instead of wasteful electric heating rods, Deaoxi turns waste heat generated by compressors into usable defrost heat, cutting power consumption and mitigating cold-capacity loss and temperature swings during defrost cycles.
Equipped with Enhanced Vapor Injection (EVI) technology, Deaoxi AI inverter hot-gas-defrost freezer and chiller unit realizes quasi-two-stage compression and increases enthalpy difference by introducing intermediate-pressure gas into compressors. The stable cooling cold room refrigeration unit operates reliably across a wide ambient-temperature range from -20 ℃ to +45 ℃. It delivers powerful refrigeration performance under high-temperature surroundings and maintains steady heating capacity in low-temperature conditions (except for cooling-only models). It satisfies diverse preservation, cold-storage and freezing requirements for various food products under different temperature settings.
Environment-friendly refrigerants such as R410A and R404A are adopted for the ODM custom cold room refrigeration unit. These refrigerants contain no chloride ion with zero Ozone-Depleting Potential (ODP) and low Global-Warming Potential (GWP). Featuring non-toxic and non-flammable properties, they exhibit outstanding thermodynamic performance for green and eco-friendly operation.
