Global Brand Case Study: Custom Refrigeration Solutions
Custom Refrigeration Requirements of Global Luxury Brands
According to EuroShop Retail Design Report 2023, demand for custom commercial refrigerators in premium retail grew 17.5% annually, with luxury brands accounting for 62%. Requirements from a Swiss watchmaker () exemplify industry standards:
- Precision temperature control: Display zone temperature variation ≤±0.3℃ (stricter than medical standard ±0.5℃)
- Specialized materials: Aerospace-grade aluminum frame + anti-reflective coated glass
- Noise limitation: Operational noise ≤28dB(A), quieter than library ambient

Project Outcomes & Verification
Third-party verification () confirmed:
- Energy efficiency: 37% energy savings vs standard units (8,200 kW·h/year)
- Maintenance cost: Predictive maintenance reduced downtime 68%
- Product preservation: Precision humidity control lowered leather mildew rate to 0.2%
"The laminar airflow system eliminated condensation on exhibits, achieving ±2.3%RH humidity control, exceeding contractual ±3%RH requirement"
Custom Design Formulas
Key calculation models applied:
- Heat load calculation: Qtotal = (1.05×A×ΔT) + (0.33×N×Plamp) + Qproduct
(A: Surface area; N: Lighting quantity; Plamp: Lamp power) - Defrost cycle: Tdefrost = [ (0.18×V×ρ×ΔW) / (Pheater×η) ] × 3600
(V: Evaporator volume; ΔW: Frost thickness)
