1. Tips for Identifying Energy-Efficient Refrigerators When Buying
Refrigerators are often the most power-hungry appliances in a household, running 24/7 without a break. When shopping, it's crucial to choose a refrigerator that is energy-efficient. Here are some incredibly useful tips to help you recognize refrigerators that will save energy.
1. Energy-Saving Label
In Vietnam, there are two types of energy labels: Confirmation energy labels and Comparative energy labels. Confirmation labels are affixed to vehicles and devices circulating in the market with energy efficiency levels meeting or exceeding the high energy efficiency set by the Ministry of Industry and Trade during each period.
Comparative labels are affixed to vehicles and devices circulating in the market with different energy efficiency levels corresponding to the five energy efficiency levels (from 1 star to 5 stars). The 5-star label indicates the best performance, providing consumers with information about the energy efficiency of this vehicle or device compared to others of the same type on the market, helping consumers choose a vehicle or device with more energy-saving consumption.
2. Products with Innovative and Advanced Technology Save Electricity
Nowadays, refrigerator manufacturers have introduced inverter refrigerators capable of saving up to 50% of electricity consumption compared to non-inverter products. The latest technology products will consume the least energy.
3. Capacity Tailored to Usage Needs
Typically, each person needs about 20-25 liters of capacity. For example, a family of 4 should buy a refrigerator with a capacity of 4 x 25 = 100 and an additional 25 liters for support, meaning 125 liters. Therefore, when buying a refrigerator, choose one with a capacity from 125 - 150 liters. Also, consider the climate of each region; in the South, you should buy a slightly larger refrigerator, and in the cold North, choose a smaller one...
4. The Tighter the Seal, the More Energy-Efficient
You can observe the tightness of the refrigerator with the naked eye. If the eye can detect it, the gap is serious. If the eye cannot see it, take a relatively thick piece of paper to different corners, close the door, and pull the paper out to see if the paper is tightly clamped. The tighter the clamp, the tighter the door. In addition to checking the tightness, also check the rotation of the door hinge for smoothness, and when opening the door, the pulling force should be from 1 to 7 kg, which is appropriate.
In addition to the key points above, remember that direct cooling refrigerators (frost) consume much less electricity than indirect cooling (non-frost) ones. Besides, if you see many refrigerators with the same design and specifications, but the one with a smaller compressor power will consume less electricity.
