What is the standard for saving electricity in the refrigerator What is the most energy saving tempe

Refrigerators are becoming more and more energy-efficient, depending on the development of energy-saving technologies for refrigerators, such as:

1. High-efficiency and energy-saving compressor;

2. By adopting measures such as double door seals, double airbag door seals, door body lock cold structure, and optimizing the matching gap between the door tank and the box bladder, the heat load transmitted to the box is reduced, so as to reduce the power consumption;

3. Foaming technology: through the use of mixed foaming, vacuum foaming and other technological measures, improve the fluidity of foam, the uniformity of foam density, reduce the size of microscopic bubbles, reduce the thermal conductivity of foam, and improve the thermal insulation performance of the box;

4. Energy-saving pressure holding magic valve;

5. Reasonable parameters;

6. High-efficiency heat exchanger.

1.First of all, consider the location of the refrigerator, the refrigerator should be placed in a cool and ventilated place, avoid direct sunlight, away from heat sources, because the high ambient temperature around the refrigerator will increase the power consumption of the refrigerator.

2.Secondly, we should pay attention to the physical and chemical properties of the objects stored in the refrigerator, and the refrigerator shall not store flammable, volatile chemical reagents or drugs, odorous, corrosive and need to be kept fresh and dry-proof items (such as fish, acid and alkali, vegetables, fruits, etc.) should be sealed with plastic film or other packaging materials before being stored in the refrigerator.

3.Do not open the refrigerator for a long time, or open the refrigerator door frequently, so that the refrigerator opening time should be short, the number of times should be less, and the opening angle should be moderate, which can reduce the loss of cold air in the box and is beneficial to energy saving.

4.If the door seal is found to be leaking, it should be replaced in time to avoid the loss of cold air from the gap in the seal, and the refrigerator will lose the function of refrigeration and heat preservation.

5.It is also necessary to consider whether the refrigerator should be intelligent about the function of frost, because the moisture in the refrigerator comes from the moisture content of the food and the moisture in the air that enters the refrigerator when the door is opened, and the moisture condenses into frost on the evaporator, the lower the temperature in the box, the faster the frost formation speed, and the thicker the frost layer, the heat transfer of the frost layer is slower than that of the metal, which will hinder the refrigeration effect of the evaporator, thereby increasing power consumption, so the refrigerator without automatic defrosting should be manually defrosted in time when the frosting thickness on the evaporator exceeds 4-5 mm.

6.Frozen food should be melted in the refrigerator before eating, which can reduce the temperature of the refrigerator and save electricity.

7.Cooked food should be cooled to room temperature before putting it in the refrigerator.

8.Do not put the food densely in the refrigerator, leave a gap between the stored food, so that the air conditioning can be convection, the temperature is uniform, the use of small packages can reduce the time of cooling, and save electricity, access and convenience.

9.To always pay attention to the refrigerator "bath", the surface of the compressor and condenser should be cleaned every 2-3 months, the more dust, the worse the heat dissipation effect, the greater the power consumption, clean the power plug when cleaning, wipe it with a damp cloth.

10.The refrigerator compressor maintains a large pressure difference between the suction side and the exhaust side after shutdown, if it starts immediately, the piston pressure of the compressor increases, and it is likely to burn the motor, so in case of power failure, it is necessary to unplug the power plug or shut down. Temporary power outages can only be turned on after 3-5 minutes.

At present, there is no star rating in China's refrigerators, and what you see is not a star rating, it uses a star rating to indicate the temperature. One star means minus 6 degrees, currently 4 stars, one of which is outside the box can be calculated or not, the average refrigerator is minus 18 degrees or 24 degrees.

7 degrees. Under the condition that the ambient temperature is around the standard temperature, the control temperature of the first gear is about 9 degrees, and the control temperature of 7 is about 1 degree. Therefore, according to the outdoor temperature change, the control of changing the gear can effectively reduce power consumption, the outdoor temperature next to the bridge is higher in summer, the temperature control can be adjusted in 3-4 gears, and the temperature cherry blossom degree is generally about 4 -6, which not only ensures the downtime rate of the refrigerator, but also ensures the refrigeration effect of the refrigerator.

On the contrary, it will cause the refrigerator to be turned on for a long time or not stopped.

Precautions for refrigeration.

1. In the hot season, do not use the refrigerator to open the door to cool the indoor temperature, this practice is wrong and will cause adverse effects.

2. Due to the low energy exchange efficiency of the refrigerator, the refrigeration capacity is lower than the heat dissipation capacity, if the door is opened, the air conditioner will run away, affecting the refrigeration effect.

3. It is best not to put food that cannot be stored in the refrigerator, so as not to freeze the food or affect the nutrients of the food.

4. If you do not use it for a long time, unplug the power plug and take out the food in the refrigerator to avoid wasting electricity and affecting the life of the internal parts of the refrigerator.

Generally speaking, refrigerators do not have a fixed temperature, and setting the temperature according to the needs of food is relatively energy-saving. Of course, the higher the temperature, the more energy saving, but in order to save energy, the refrigerator will not play the role of freezing, and the food will spoil, and the gains outweigh the losses. 3-5 gears, the temperature is 16-30.

Maintaining such a temperature is the most energy-efficient. Under normal circumstances, the temperature of the refrigerator is about 4 degrees, and the higher the temperature adjustment, the more power saving. The lower the gear, the lower the gear, the more power saving.

However, the temperature of the refrigerator must meet the requirements of food freezing and preservation, under normal circumstances, the freezer should be about minus 18 degrees, and the refrigerator room is between 4-8 degrees. The wide attack of the thermostat is mechanical, and the gear should be adjusted according to the temperature of the season, the lower gear (1-2 gear) should be adjusted in summer, the middle gear should be adjusted in spring and autumn, and the gear should be adjusted higher in winter. Carefully erect the correct adjustment of the refrigerator temperature controller to reduce power consumption, The refrigerator temperature control knob is marked with a number, which represents the control range of the temperature in the refrigerator.

The higher the number, the higher the temperature of the control. The indication range of the thermostat in different seasons is: summer 2 3;Spring-Autumn 3

The higher the temperature of the refrigerator, the more power saving. But to meet the food freezing preservation. Under normal circumstances, the frozen room should be kept at about minus 18 degrees, and the refrigerated room should be more suitable between 4-8 degrees.

Today's refrigerators have an energy efficiency label on the door with the refrigerator's power consumption rating.

Energy efficiency can also be calculated by calculating the ratio between the refrigerator's power and its rated cooling capacity.

Energy efficiency grade: is a grading method that indicates the energy efficiency grade is a grading method that represents the difference in energy efficiency of household appliances, in accordance with the relevant provisions of national standards, at present, China's energy efficiency standard friends Suizhi will divide energy efficiency into five grades. Level 1 means that the power saving of the product has reached the international advanced level, and the energy consumption is the lowest; Level 2 indicates that the product is more power-saving.

Level 3 means that the energy efficiency of the product is the average level of the Chinese market; Level 4 indicates that the energy efficiency of the product is below the market average; Level 5 is the product market access index, and products below the requirements of this level are not allowed to be produced and sold. In terms of efficiency, the first-level energy efficiency is more energy-saving than the second-level energy-saving and dust-saving.

Common sense of refrigerator use:

1. After the new refrigerator is purchased, it should be wiped several times with a clean rag, but do not close the door after wiping it clean, open the door to let the odor inside dissipate, or use an electric fan to blow it inside to speed up the emission of the odor, and then use electricity.

2. After the new refrigerator is carried back, it should be left to stand for a few hours before powering on the test.

3. The refrigerator should be placed in a cool and ventilated position, and a certain amount of space should be left around it to facilitate the ventilation and heat dissipation of the refrigerator and improve its refrigeration efficiency.

4. When the machine is powered on, the temperature setting of the freezer should be adjusted at minus 18 degrees, and the temperature of the refrigerated room should be about 5 degrees. If there is no food in the freezer that needs to be frozen for a long time, the temperature can be appropriately increased, so that it is more energy-saving. The same goes for the refrigerator, if there is no special food request, you can turn the problem up to between 8-12 degrees, so that it is more energy-efficient, especially in summer, when the power saving is particularly obvious.

However, if there is yogurt in the refrigerator, the temperature should be between 2-6 degrees. The mechanical thermostat should adjust the size of the digital gear according to the ambient temperature of the season, adjust the smaller digital gear in summer, adjust the middle gear in spring and autumn, and adjust it in the larger digital gear in winter. The smaller the gear adjustment, the more power saving.

5. When the machine is powered on, do not put in the food first, wait for the temperature in the refrigerator to drop and stabilize, and then slowly put in the food after the compressor starts and stops normally, and do not put too much food at one time to avoid the load of the compressor.

6. The food placed in the refrigerator should be sealed and wrapped in a container or food bag to avoid odor caused by mutual odor.

7. If it is a direct cooling refrigerator, when the frost thickness in the freezer exceeds 6 mm, it is necessary to manually defrost it in time to avoid reducing the refrigeration efficiency.
