Product Summary
The EXTRCOOL AI-driven full inverter refrigeration unit is a split-type system engineered for industrial and commercial cold chain applications. Key components include a multi-row L-shaped large evaporator, EVI dual-rotor DC inverter compressor (GMCC), DC variable-speed outdoor fan, and dual electronic expansion valves (EEV/EVI). The system provides precise temperature control, energy-efficient inverter regulation and stable low-temperature performance, with optional 5G remote management.

Design & Reliability
The unit incorporates condensate drain frost protection heating, large-pitch fins (2.4–6 mm), and a stainless-steel sheet casing with corrosion-resistant coating. The chassis integrates a hot-refrigerant deicing system to prevent evaporator and base pan icing. Accurate control and intelligent defrost cycles reduce manual intervention and support continuous operation in demanding environments.

Operational Advantages
The AI-driven inverter control adapts compressor speed, cooling output and defrost timing in real time using ambient and operational data (temperature, storage load, door cycles, equipment status). This adaptive control minimizes temperature fluctuations, reduces product loss and lowers lifecycle energy and maintenance costs compared with traditional fixed-speed units.

Core Components & Key Design Features

• Wide ambient operating range: reliable performance from -35°C to 52°C.
• High-efficiency evaporator options: external or inner rotor fans with 2.4–6 mm large-pitch fins for improved heat exchange.
• Corrosion-resistant construction: stainless steel coated components and customizable fin options for harsh environments.
• Comprehensive anti-icing: condensate drain heating and hot-refrigerant chassis deicing for uninterrupted operation.

AI Frequency Conversion Advantages

• Improved energy efficiency: higher COP and lower operating costs versus fixed-speed systems.
• Faster cooling response: broad operating range and quick-start control for rapid temperature recovery.
• Extended equipment life: frequency modulation reduces start/stop cycles and component wear.
• Precise temperature stability: tight control to protect product quality.
• Low noise operation: suitable for varied site conditions.
• PV compatibility: can operate with photovoltaic power without additional inverter in many cases.

Hot Fluoride Defrosting Benefits

• Ultra-short defrost cycles: defrost completes in minutes compared with electric defrost methods.
• Minimal temperature variation during defrost: protects product freshness.
• Lower operating cost: higher thermal efficiency versus electric defrost.
• Reduced maintenance: stable defrost method decreases part replacement frequency.

Hot Fluorine Ice-Melting Features

• Controlled ice removal: preheating avoids mechanical scraping damage to the evaporator.
• Energy savings: efficient thermal defrost reduces power consumption.
• Automatic operation: initiates under severe icing conditions to prevent shutdowns.
• Operational safety: high-temperature exhaust melts ice reliably even with unstable power supply.

Application Fields

• Precise temperature control across a wide range: AI-driven frequency conversion enables ±0.5°C control within -20°C to 40°C.
• Pharmaceutical and chemical storage: precision control with redundancy options and low fluctuation.
• Cold chain warehousing: multi-zone temperature management and cost-effective frequency control.
• Food processing and long-term cold storage: meets rapid-freezing and continuous operation demands.
• Retail and hypermarkets: compact footprint, low noise and simplified maintenance.
• Fruit ripening and precoooling: fast precooling and controlled ripening with precise temperature rise capability.
