key factors to evaluate their quality:
High quality of commercial supermarket refrigerators (also known as commercial display freezers) is crucial for food preservation, energy efficiency, and operational performance. Below are the key factors to evaluate their quality:
- Temperature Uniformity: Internal temperature variation should be ≤2°C to prevent uneven cooling or frost buildup.
- Environmental Adaptability: Should operate stably even in high-temperature or high-humidity conditions (e.g., near store entrances).
- Eco-Friendly Refrigerants**: Use low-GWP refrigerants (e.g.,R404a, R290, R600a) compliant with regulations (e.g., EU F-Gas standards).
- Insulation Layer: Polyurethane foam thickness ≥50mm, high density to minimize cold loss.
- Sealing Performance: Magnetic door gaskets (test by inserting a bill) and anti-condensation design.
- Defrosting Technology: Frost-free air cooling (for freezers) or manual/auto-defrost (cycle should be specified).
- Smart Controls: Digital temperature panel, remote monitoring (Wi-Fi), and fault alarms.
- Food-Grade Materials: Certified by FDA or EU 10/2011, ensuring non-toxic and odor-free materials.
- Impact Protection: Rounded edges, tempered glass with anti-shatter film (optional).
- Service Network: 24/7 support
key factors for evaluating evaporator quality
Evaporator is the core component of a refrigerator's cooling system, and its quality directly affects cooling efficiency, energy consumption, and equipment lifespan. Below are the key factors for evaluating evaporator quality:
- Copper Tube with Aluminum Fins: Excellent thermal conductivity (copper for high-pressure resistance, aluminum for lightweight), used in mid-to-high-end models.
- Hydrophilic Aluminum Coating: Prevents frost buildup and water retention, improving heat exchange efficiency.
- Anti-Corrosion Treatment: Surface should be anodized or epoxy-coated to delay rust (especially in coastal areas).
- Pipe Layout: U-shaped or serpentine coil design minimizes refrigerant flow resistance and avoids "dead oil zones."
- Welding Process: Seamless brazing or high-frequency welding, leak-free (verifiable via helium or pressure testing).
-Temperature Uniformity: Even evaporator distribution (e.g., multi-vent design) ensures internal temperature variation ≤2°C.
- **Refrigerant Compatibility**: Supports eco-friendly refrigerants (e.g., R290/R404A) without efficiency loss.
- Frost-Free Air Cooling: Uses fans for forced circulation, eliminating manual defrosting (ideal for freezers).
- Electric Defrosting: Heating element power must match evaporator size to prevent incomplete defrosting or overheating damage.
- Drainage Design: Sloped drip tray + drainage channel prevents ice buildup or bacterial growth.
- Ease of Cleaning: Modular or detachable design simplifies dust and bacteria removal. - Lifespan: High-quality evaporators last ≥10 years (with regular descaling maintenance).
- Certifications: Complies with ISO 9001, UL/CE safety standards, or GB/T 23133-2019 (China).
