🏠 1. Household Scenario: Fix High Power Consumption and Noise Disturbance.
Key Model: Donper VFL Series Ultra-High Efficiency Inverter Compressor (e.g., VFL090CY1H)
-
Energy Saving: Boasts a COP (Coefficient of Performance) of up to 2.18, a figure certified by national-level appraisal in 2023 and recognized as internationally leading . For a 3-person household, this translates to annual electricity savings of nearly RMB 300 when paired with standard-sized refrigerators.
-
Quiet Operation: Integrates a patented snake-shaped connecting pipe muffler and compressor core vibration-damping structure , reducing operating noise to 25 dB — equivalent to the sound of page-flipping in a library — and eliminating nighttime disturbances.
🛒 2. Convenience Store Scenario: Avoid Malfunctions and Low Cooling Efficiency.
Key Model: Donper K Series Commercial High-Efficiency Compressor (e.g., K375CZ1)
-
Reliability: Features high-strength piston and cylinder components tested through thousands of high-low temperature cycles , supporting 24/7 continuous operation — a critical requirement for convenience store freezers — and minimizing cargo spoilage losses from malfunctions.
-
Fast Cooling: Restores freezer temperature to -5°C within 5 minutes after frequent summer door openings , ensuring the freshness of beverages, ice cream, and other perishables even during peak customer flow.
🏥 3. Medical Scenario: Control Temperature Fluctuations and Extreme Environment Adaptation.
Key Model: Donper VC Series Deep-Freeze Compressor (e.g., VC70EZ)
-
Precise Temperature Control: Achieves a cooling temperature of -86°C — a breakthrough developed with the Institute of Physics and Chemistry, Chinese Academy of Sciences — with a 24-hour temperature fluctuation ≤ 1°C, preventing vaccine and biological sample degradation.
-
Environmental Adaptability: Maintains stable operation even in unheated -20°C environments , safeguarding medical cold chains in remote rural hospitals where heating infrastructure is limited.
☕ 4. New Tea Beverage Scenario: Solve Insufficient Ice Capacity and Space Limitations.
Key Model: Donper VFL Series R290 Rotary Compressor (e.g., VFL070CU1)
-
High Ice-Making Capacity: Delivers 20% higher cooling efficiency than conventional models ; when paired with Donper ZFG160 series ice machines , it produces 40 kg of ice per hour, meeting peak morning demand for brands like Mixue Bingcheng.
-
Space-Saving: With a compact design inherited from Donper’s material-saving technology , it fits desktop ice machines, optimizing space utilization in small beverage stores.
