1. Dangerous Food Safety Temperature Ranges

• The Problem: The listed temperature range for Refrigeration is 8℃ to -5℃.

• The Food Safety Risk: Under global food safety standards, commercial refrigeration must keep food below \circ\text{C}\circ\text{F to prevent rapid bacterial growth (the "danger zone"). Setting a refrigerator to \circ\text{C} will cause food to spoil quickly and fail health inspections. Furthermore, a refrigerator should not run down to \circ\text{C} unless it is a dedicated meat chiller, as it will freeze and ruin standard fresh produce, dairy, and eggs.

• The Fix: Adjust the temperature definitions to match industry standards:

  • Refrigeration Range: ^\circ\text{C}\text{ to }4^\circ\text{C} (or \circ\text{C}\text{ to }8^\circ\text{C}only if explicitly labeled as a beverage cooler).

  • Freezing Range: ^\circ\text{C}\text{ to }-22^\circ\text{C} (Freezing at \circ\text{C} is just the freezing point of water; commercial freezers must store food much colder to maintain long-term quality).

2. The "Direct Cooling" Frost Trap

• The Problem: The sheet lists the Cooling Method as Direct cooling.

• The Operational Nightmare: Direct cooling (static cooling coils built into the walls) works well for small residential mini-fridges, but it is highly inefficient for large commercial 4-door and 6-door cabinets. In a busy kitchen where doors are constantly opened, direct cooling causes massive frost buildup on the walls, uneven hot/cold spots, and slow temperature recovery. High-end commercial kitchens expect dynamic cooling.

• The Fix: Change the specification to Ventilated / Fan-Assisted Forced Air Cooling. This ensures even temperature distribution across all shelves and rapid recovery after the doors close. If it truly is direct cooling, you must explicitly add a Manual Defrost Schedule warning to the guide.

3. Confusing Electrical Ambiguity

• The Problem: The table lists Voltage as 220V / 380V.

• The Reality: A buyer or electrician needs to know exactly what infrastructure to pull to the kitchen line before delivery. Standard single-compressor refrigerators (even large 4-door or 6-door models) almost always run on single-phase 220V. Three-phase 380V power is usually reserved for massive rack systems, remote condensing units, or blast freezers.

• The Fix: Separate this spec by application: 220V–240V / 50Hz (Standard Models) and 380V / 50Hz (Only for specialized dual-compressor or custom blast-freezing variants).

4. Missing Compressor and Refrigerant Data

• The Problem: The sheet is completely blank regarding the engine of the machine. Commercial buyers need to know the refrigerant gas type for environmental compliance (especially with modern bans on older HFCs) and whether the compressor is heavy-duty.

• The Fix: Add these rows to the specification table:

  • Refrigerant: R290 (Eco-friendly propane, which is standard for modern energy-efficient commercial reach-ins) or R404A / R134a.

  • Compressor Type: Heavy-duty commercial brand (e.g., Embraco or Secop).
