Introduction: Everyone has different views on the energy efficiency of various types of home appliances. When consumers purchase home appliances, if they want to judge the energy efficiency level of a product, they can generally only judge the energy efficiency level of a product through some labels affixed to the machine. Energy efficiency label to get a rough idea of ??the energy efficiency level of a product. These labels mainly consist of energy efficiency levels and energy efficiency reference values. Energy efficiency grade

Energy efficiency grade: It is a grading method that indicates the difference in energy efficiency of household appliances. According to the relevant provisions of national standards, my country's current energy efficiency label divides energy efficiency into five levels.

◆ Level 1: The product’s power saving has reached the international advanced level and the energy consumption is the lowest;

◆ Level 2: The product is relatively energy efficient;

◆ Level 3 : Product energy efficiency is the average level of the Chinese market;

◆ Level 4: Product energy efficiency is lower than the market average;

◆ Level 5: It is a product market access indicator. Products below this level are not allowed to be produced and sold. Label reference values ??

In addition to the prescribed energy efficiency levels, the reference values ??on the energy efficiency labels of different household appliances will be different.

Refrigerator

For refrigerator products, in addition to the conventional classification, there is also a 24-hour power consumption worth referring to on the energy efficiency label. Through the given value, we can have a rough understanding of it. The electricity consumption of this refrigerator in one day.

Washing machine

Among the energy efficiency labels of washing machine products, it is worth referring to the power consumption, water consumption and washing ratio of a working cycle. If the conventional energy efficiency classification can meet your Purchasing requirements, then some other parameters are also worth referring to, and they are also easier to understand.

Air conditioning

For air conditioning products, the products currently sold on the market are generally divided into three energy efficiency levels. The energy efficiency label will also give the energy efficiency ratio, input power, cooling Quantitative data. The energy efficiency ratio is the ratio of the rated cooling capacity to the rated power consumption. It can also be understood as the ratio of the marked cooling capacity to the input power. Often, the higher the energy efficiency ratio, the more power the air conditioner will save.

Rice cookers

In addition to the conventional classification, the energy efficiency label on the rice cooker will also have labels such as thermal efficiency value, standby power, heat preservation energy consumption, inner pot material, etc. The higher the thermal efficiency value , rice cookers are relatively more energy-saving.

Microwave oven

For microwave ovens, the energy efficiency label will also have efficiency value data. The higher the efficiency value, the more power the microwave oven saves.

LCD TV

Nowadays, the popularity of flat-panel TVs has been very high. The energy efficiency label of flat-panel TVs will be marked with the LCD TV energy efficiency index and passive standby power. The lower the energy efficiency index, the TVs will become more energy efficient.

Electric water heater

Electric water heater is definitely a big consumer of electricity. The energy efficiency label on the electric water heater will have a 24-hour inherent energy consumption coefficient and hot water output rate. The 24-hour inherent The energy consumption coefficient refers to the ratio between the actual energy required to maintain the water temperature at the set temperature and the energy limited by the standard without using a water heater. The lower the ratio, the better the insulation effect of the water heater. The higher the value of the hot water output rate, the better. Generally it is greater than or equal to 70.

Generally speaking, the information on the energy efficiency label still has certain reference value, but most people are not clear about the specific meaning of these data. If you are really concerned about the energy consumption of home appliances, it is recommended to You can understand the meaning of the identification value in advance.
