How to deal with the daily electricity consumption and power outage of the refrigerator
Certainly! Here's the English translation of your detailed refrigerator power consumption guide:

Estimated Daily Cost (at ¥0.6/kWh)
|
Key Reference
|
|
Compact Fridge (100-200L)
|
0.3-0.6 kWh
|
¥0.18~0.36
|
Lab tests of Energy Star models14
|
|
Mid-Size Fridge (300-400L)
|
0.8-1.2 kWh
|
¥0.48~0.72
|
Inverter compressor tests13
|
|
Large Fridge (500L+)
|
1.5-2.5 kWh
|
¥0.9~1.5
|
Summer usage data (French door models)16

Note: For the same capacity, an Energy Star Level 1 fridge saves 0.4-0.7 kWh/day (30%~50% less) vs. Level 328.
Key Factors Affecting Consumption
-
Ambient Temperature
-
35°C: Power use ↑50%+ (compressor runs longer)16
-
<10°C: May drop to <0.5 kWh/day (some require low-temp compensation)1
-
Usage Habits
-
Opening door >20x/day: Consumption ↑25%26
-
Adding 60°C hot food (500g): +0.05 kWh per instance3
-
Frost layer ≥5mm: Efficiency ↓30%3
-
Load Capacity
-
60%~70% full is optimal – overcrowding blocks airflow, underfilling increases cold loss6
3-Step Calculation Method
-
Check specs: Find rated power (e.g., 120W = 0.12kW)2
-
Estimate runtime: Compressor typically runs 8~12 hrs/day (at 25°C)2
-
Formula:
Daily use (kWh) = Power (kW) × Runtime (hours)
Example: 120W fridge running 10 hrs → 0.12kW×10h=1.2 kWh27
Energy-Saving Tips
-
Temperature Settings
Set fridge to 5°C (saves 15% vs 3°C), freezer at -18°C is sufficient6
-
Maintenance
Test door seal (replace if paper slips out), clean condenser every 6 months6
-
Storage Strategy
Cool hot food first, use vacuum containers to reduce cold air loss26
Cost Estimation Example
A 400L Energy Star Level 1 fridge (1 kWh/day):
-
Monthly cost: 1 kWh × 30 days × ¥0.6 = ¥18
-
Annual cost: ~¥216 (may rise to ¥260 in summer)38
Regular maintenance + optimized habits can reduce costs by 20%~30%26.
What should I do if there is a power outage at home?
Various refrigerators can use the Home savings system provided by SonecPower, which provides 24-hour uninterrupted power supply service
