The refrigerator is a refrigeration equipment that maintains constant low temperature, and it is also a civilian product that keeps food or other items keeping constant low temperature.There are compressors and ice -making cabinets or boxes used to freeze in the box, and a storage box with a refrigeration device.The volume of household refrigerators is usually 20 to 500 liters.
How to use refrigerators
Temperature compensation switch
The use of refrigerator temperature compensation switch is to bring a climate -climate -climate -climate -climate -to -climate -to -see refrigerator based on the characteristics of the temperature difference between the north and south regions of my country. Under the situation of low ambient temperature (below 10 ° C), please turn on the temperature compensation switch to use it normally.When the ambient temperature is low, if the temperature compensation switch is not turned on, the number of working times of the compressor will be significantly reduced or not working. The boot time is short and the stop time is long.Open the temperature compensation switch.(The principle is that when the ambient temperature is lower than 10 degrees Celsius, you need to turn on the switch to warm the refrigerators refrigerator, so that the refrigerator is passively working, so that the temperature of the freezing room can keep the temperature and freeze.) Opening the temperature compensation switch does not affect the refrigerator.Life life.When the winter is over, the ambient temperature rises, and the ambient temperature is higher than 15 ° C, please turn off the temperature compensation switch. In this way, the compressor can be avoided frequently and save electricity.
thermostat
The refrigerator thermostat uses how to use the refrigerator during the use of the refrigerator, and its working hours and power consumption are greatly affected by the environmental temperature. Therefore, we need to choose different gears in different seasons.Open high -end.When the environmental temperature in summer is high, it should be used in the weak gear of 2 or 3. When the environmental temperature is low in winter, it should be used in the strong gear 4 or 5. For the reason: in summer, the environmental temperature is high (up to 30 ° C), the freezer indoors in the freezer room, the freezing room indoorsIf the temperature is hit (4, 5), and below -18 ° C, the temperature difference between the inside and outside is large, so it is difficult for the temperature in the box to fall 1 ° C, and then, it will also be lost through the box insulation layer and door sealing air-conditioning.Speed ??up, this time the boot time is very long and the stop time is very short, which will cause the compressor to run for a long time at high temperature, which consumes both power and easy to damage the compressor.If it is changed in the weak gear (2 and 3) at this time, the refrigerator will be significantly shortened, which will reduce the wear of the compressor and prolong the service life.Therefore, the temperature control is adjusted to the weak in summer.When the environmental temperature is low in winter, if the temperature controller is still adjusted to the weak gear, the temperature difference between the inside and outside is small, and the compressor will not be easy to start. The refrigerator of the monocular refrigeration system may also have a freezer.
The correct setting temperature of the refrigerators refrigerator is 5-7 degrees, which can ensure the freshness of food preservation, and the temperature setting is too low to cause waste.
Frost
1. Live at home, the refrigerator is indispensable.The inner wall of the refrigerator is frost, and water vapor comes from there.
It is understood that most of the water vapor comes from the air. When people store food to open the refrigerator, the indoor air and gas in the refrigerator are freely exchanged, and the humid air in the room quietly enters the refrigerator.There are also some water vapor from food stored in the refrigerator, such as cleaning vegetables and fruits in the fresh -keeping box. The water in foods such as vegetables evaporates, and it is condensed into frost after cold.Especially in summer, the indoor temperature is high, the humidity is high, and the temperature difference between the room temperature and the temperature in the refrigerator.When the refrigerator was turned on, a cold air flow from the inside, and the indoor air drilled into the refrigerator.In a little time, the refrigerator surface is condensed into a layer of white frost.It is found that even if there is nothing in the refrigerator, a thick layer of frost will be knotted in the refrigerator often opened. It can be seen that a large part of the water vapor in the refrigerator comes from water vapor in the air.
2. There are high tricks in the refrigerator frost
Some refrigerators need to be defrosting. The frost of artificial refrigerators is both time -consuming and laborious, and the frosting effect is very poor.Here I recommend a frosty high trick.
According to the size of the refrigerators refrigerator, cut a slightly thicker plastic film and stick it on the frost wall of the refrigerator. There is no need to use any glue.During the frost, take out the food in the refrigerator, and then remove the plastic film down and shake. The frost can be completely fell off, then re -paste the film, put it in the food, and continue to use it.
1. Stay away from the heat source and keep the gap
Every time the temperature around the refrigerator increases 5 ° C, the inside is increased by 25%.Therefore, it is better to place as much as possible to stay away from the heat source, and it is better to ventilate and shade.Dont put hot food directly into the refrigerator and put it in room temperature.Foods in freezing rooms are best wrapped in plastic bags, which can be frozen quickly, which is not easy to dry, but also avoids moisture to become frost; food should not be too full. There should be a gap between the wall of the refrigerator to facilitate the flow to facilitate the flowingAir conditioning; frozen foods, it is best to transfer it to the refrigerator to thaw.
Second, frequent open doors
If the door is too frequent, on the one hand, the power consumption of the refrigerator will increase significantly, and it will also reduce the service life of the refrigerator.Due to the large box door of the refrigerator, if the number of doors opens more, the air -conditioning in the box and the warm and humid air outside the box will enter the temperature in the box.At the same time, the humid air entering the box can easily speed up the surface of the evaporator, and the frost layer is thickened.Because the thermal conductivity of the frost is much smaller than the thermal conductivity of the evaporator material, it is not conducive to the thermal conductivity, resulting in the slow decrease in the temperature in the box.If the thickness of the frost layer of the evaporator is greater than 10 mm, the heat transfer efficiency will decrease by more than 30%, resulting in a significant reduction in refrigeration efficiency.In addition, when the door of the box is turned on, the lights in the box are turned on, which consumes both electricity and emitting heat, which is obviously not conducive to energy saving.
Third, the power outage and freshness, the peak of the peak consumption
If you are worried about the "electric shortage" during the peak period of electricity, we recommend that you better use a refrigerator with the function of "timing electricity, power outages and preservation".This kind of refrigerator can still refrigerate and keep fresh in the case of pulling power limit and sudden power outage for 20 hours. Moreover, its "time -sharing" function can avoid refrigerating during the peak of electricity prices, and automatically realize the "wrong" error.Peak electricity. "
Taking Beijing as an example, if the electricity price from 22 oclock in the evening to 8 am the next day is a quarter of the peak electricity price, consumers can enter the refrigerator control panel from 22 to 8 oclock.In this way, the refrigerator refrigeration system automatically turns on at 22 oclock in the evening, carried out refrigeration and cooling. After the electricity price rises at 8 am, the battery drives miniature fan, and the cold amount of the refrigerator is sent to the food in the refrigerator to fully use the low priceValley electricity avoids expensive peak power.
Summer prevention measures
The weather starts to get hot, and the usage rate of the refrigerator is higher, but you know, the refrigerator can only extend the time limit for saving food, not a "safe".If it exceeds a certain period of time, various foods stored in the refrigerator will lose the original delicious and nutritious ingredients.Because some bacteria and viruses may have been brought in when putting food, the temperature of the refrigerator refrigerator is not zero. Many germs can lurk in a low temperature environment. After waiting for a long time, it will wait for a lot of breeding.Rotten and deteriorate.Therefore, the following preventive measures must be taken:
1. The food in the refrigerator must be clean and clean.Fruits, vegetables and other raw food can be washed and drained.Raw fish and chicken and ducks should be removed after the internal organs should be removed before putting it in the refrigerator.
2. After the refrigerator is used for one to two weeks, the soft cloth immersed in warm water is used to wipe it once or twice. Do not use laundry powder, decontamination powder and gasoline to wipe.
3. Do not save raw and cooked food in a container. Do not contact raw meat and fish to prevent bacterial pollution from raw meat and fish.
4. There should be a certain gap between the food in the refrigerator. Do not close the left, right and rear walls of the refrigerator, so that the air -conditioning can flow, and the puts in the refrigerator should not be over.
5. Try to reduce the time and number of the refrigerator door and reduce the entry of external heat.The authors experience of putting food in the refrigerator should not exceed five to seven days. If the food taken out, it should not be eaten if it finds moldy, corruption and taste.
6, hot weather in summer, cold drinks, frozen drinks, fruits, food, etc. taken from the refrigerator should be placed slightly at room temperature before eating to avoid sudden cold drink stimulation caused by stomach pain, enteritis, diarrhea, or hypertension that the original sufferings, and the original suffering.Coronary heart disease, brain stroke and other illnesses have been seriously ill, and the elderly and children pay particular attention to them.
7. The placement of the refrigerator is also particular. Generally, you should pay attention to the following two issues:
When placing the refrigerator, 5-10 cm on both sides, 10 cm above, and 10 cm back on the rear side should be reserved, which can help the refrigerator heat dissipation.Do not put on electrical appliances such as audio, television, microwave oven, the heat generated by these appliances increases the power consumption of the refrigerator.
How to clean and maintain the refrigerator
9 steps for cleaning the refrigerator:
1. Clean the refrigerator housing every day, and wipe the shell and handle of the refrigerator every day with a slightly wet and soft cloth.
2. Clean the power supply before cleaning the inner orchid, and take out the food in the refrigerators refrigerated room.
3. Dip the soft cloth dipped in water or clothing, scrub it gently, and then dip the cleaning water to wipe it.
4. Remove the accessories in the box and wash it with water or detergent.
5. When cleaning the "switch", "lighting" and "temperature control" of the refrigerator, twist the rag or sponge.
6. After the inner wall is cleaned, you can use a soft cloth dipped in gly glycerin (medical Kaishu) to wipe the inner wall of the refrigerator again, which will be easier to wipe next time.
7. Wipe the seal with the cloth soaked with alcohol.If you do n’t have alcohol at hand, wipe the dense seal with 1: 1 vinegar water, and the disinfection effect is very good.
8. Clean the ventilation grid on the back of the refrigerator with a vacuum cleaner or soft brush. Do not use wet cloth to avoid rust.
9. After cleaning, insert the power, check whether the temperature controller is set in the correct position.
Regular maintenance can extend the life of the refrigerator.Before maintaining the refrigerator, you must unplug the power plug.
1. Frequent cleaning the back of the refrigerators back or bottom condenser and the compressor.Can use vacuum cleaner or brush dust removal.Be careful not to wipe the refrigerator and dust on the compressor with a wet cloth.
2. When the refrigerator is discontinued for a long time, the power should be cut off first, all the food in the box should be removed, clean the inside and outside of the box, open the door for several days, so that the inside of the box is fully dry and disperse the odor in the refrigerator.
3. Check the drain pipe.If the drainage pipe is blocked, the water will leak into the refrigerator.Use a wire to stab a drainage pipe to remove things accumulated on the drain pipe.
4. Do not ignore the cleaning of the door sealing strip. Dilute the bleach with 10 times water and wash them with a toothbrush. Finally, rinse the bleach with water.The dirty and dirty of the adhesive strip will affect the sealing of the refrigerator and increase the power consumption.
5. Check the temperature of vibration, noise and compressor.When running the compressors case during operation, there should be no obvious vibration dysfunction. The sound of the compressor should not be heard during the day.
6. Pay attention to check whether there are cracks on the electric source line to prevent leakage.
7. Wash and dry the inside and outside of the refrigerator with warm water or neutral detergent.
