Summer is here, and the high temperature makes the shelf life of food at room temperature greatly shortened, and many foods are stored in the refrigerator. Because the temperature in summer is relatively hot, it has become a common question for people to turn on the appropriate gear for the refrigerator in summer. If the temperature is too low, it will waste electricity, and if the temperature is too high, the food will be damaged easily, so it is necessary to adjust a suitable gear. For the health of food, everyone also needs to know the methods used in the refrigerator in summer. So how to use the refrigerator in summer? What are the precautions? Let’s take a look together.
A few gears are suitable for the refrigerator in summer
The temperature control knob of the refrigerator generally has five gears of 0, 1, 2, 3, 4, 5, or 0, 1, 2, 3, 4, 5, 6 and 7 gears, the 0th gear here is the stop gear, and the 5th, 6th, and 7th gears are the forced cooling gears. When the thermostat is adjusted to the forced cooling gears, the compressor will continue to operate due to the low control temperature. Work, the refrigerator is almost always in a state of non-stop.
The larger the number of the thermostat, the lower the temperature of the freezer, generally adjust the five gears 2-3 gears, and the 7th gear will control the freezing after the 3-4 gears -18 Refrigerate at 5 degrees without further adjustment.
In summer, the temperature is high, and the internal temperature of the refrigerator will be affected. Correctly adjusting the temperature file can save electricity. The temperature range of the refrigerator is from zero to seven, and it can be adjusted to 2 to 3 in summer, which can save electricity and better refrigerate and preserve food. The higher the temperature number on the refrigerator, the lower the temperature. If the refrigerator temperature is adjusted to above 3 in summer, the compressor will actually have enough refrigerating temperature in order to meet the low temperature of the refrigerating room, and increase the working load, which will not only consume electricity. And damage the life of the refrigerator.
Maintenance of the refrigerator in summer
We should regularly clean the condenser and compressor of the refrigerator. These two are very important refrigeration parts of the refrigerator. kind of destruction. The refrigerator should be placed in a ventilated and dry place at home. After each use of the refrigerator, the refrigerator should be cleaned in time, which can also kill some pathogenic bacteria and reduce the occurrence of gastrointestinal diseases.
How to adjust the refrigerator to save electricity in summer
Correctly adjusting the temperature of the refrigerator can save a lot of electricity and prolong the service life of the refrigerator. Many families’ refrigerators are not full, which will lead to overcapacity. You might as well put some foam in the refrigerator to concentrate the food, which can not only maintain the refrigeration temperature, but also reduce the power consumption of the refrigerator. It really kills two birds with one stone.
The temperature of the freezer compartment of the refrigerator is controlled by the temperature in the refrigerator compartment, and the temperature control knob is in the refrigerator compartment. The temperature in the refrigerator is generally between 4 and 8 degrees. In winter, the indoor temperature is close to this temperature. If the thermostat knob is still at 3 or less than 3, the refrigerator compressor will rarely start, although the refrigerator The temperature in the freezer can meet the requirements, but the temperature of the freezer cannot reach below minus 18 degrees, the food is easy to deteriorate, and the food is thawed and melted in severe cases. In summer, the ambient temperature is relatively high. If the knob of the thermostat is still at 3 or greater than 3, the compressor will work for a long time in order to meet the temperature requirements in the refrigerator compartment, although the temperature in the freezer compartment is even lower than minus 18 degrees. The temperature of the refrigerator is also very low, but it causes waste of electric energy and shortens the service life of the refrigerator, which is also not what we want. Therefore, adjusting the knob of the refrigerator thermostat correctly can keep us fresh and save electricity.
The temperature of the electronic refrigerator can be set directly on the panel of the refrigerator. The temperature of the freezer should be minus 18 degrees, and the temperature of the refrigerator should be between 4-8 degrees. Of course, if there is less food in the refrigerator, or there are no special requirements, and the storage time is short, in the case of food freezing and preservation, the higher the temperature of the refrigerator is, the more power is saved.
Precautions for the use of refrigerators in summer 1. A good electricity environment is necessary
The circuit in the home must have a leakage protector, so that when the electrical appliance is short-circuited, the circuit can be directly tripped to avoid fire and other problems. Therefore, the electrical environment in the home is good to ensure the safety of electrical appliances. In addition, the voltage in some areas is unstable, fluctuating high and low. This kind of problem should also be consulted with the relevant local departments or property management to find a solution. Otherwise, it will cause different degrees of damage not only to the refrigerator, but also to other home appliances.
2. The old refrigerator at home should not be overaged in service
After a few years of use, the electrical appliances and core components will be worn out, and they should be replaced when they reach the limit. Although many refrigerators can continue to be used after more than ten years, the noise and power consumption will increase, because the circuit is aging, and some of the virtual circuits consume a lot of power for no reason, resulting in increased power consumption. This part of the electricity consumed will be converted into heat, which is also a fire hazard. The aging of the compressor and the poor sealing can also cause increased noise, increased power consumption, and even a hidden danger of explosion. Therefore, the service life of the refrigerator is best controlled within 10 years.
3. If abnormality is found, repair it in time
Some refrigerators’ thermostats may fail unexpectedly, resulting in unnecessary power consumption and even fire. How to avoid it? If you find in your life that the refrigerator works continuously without stopping (it can be judged from the presence or absence of sound), it can prove that the refrigerator thermostat is out of order. At this time, the thermostat must be replaced.
How to use the refrigerator in summer
1. Don’t put hot food in the refrigerator immediately
This is mainly because if hot food is put into the refrigerator immediately, it will not only affect the food in the refrigerator At the same time, there will be repeated refrigeration of the refrigerator, which consumes a lot of electricity. At the same time, when refrigerating food in the refrigerator, it is best to use plastic wrap to avoid the growth of bacteria in the refrigerator.
2. When the food in the refrigerator is reheated, it should be cooked thoroughly
The most suitable temperature for the reproduction of most microorganisms is around 37 degrees Celsius, but some can reproduce rapidly at above 20 degrees Celsius. Medium low temperature does not mean that bacteria will no longer reproduce, but in low temperature, the reproduction of bacteria is slightly slower, thereby delaying the deterioration of food, but it cannot kill microorganisms.
Generally, the temperature of the refrigerator compartment is about 4℃-10℃. The food is taken out of the refrigerator and heated immediately. It requires a gradual heating process. From 4°C to 40°C, it is just the right temperature for bacteria to multiply. Gradual heating is equivalent to creating a good environment for bacteria to multiply. The leftovers will inevitably have symptoms such as diarrhea.
3. Tropical fruits are not suitable for long-term refrigeration
Generally, fruits in the refrigerator, such as watermelon and grapes, are seasonal fruits in summer, just to make the fruits more refreshing It is not suitable for long-term storage, because generally tropical fruits are difficult to withstand low temperature, which will lead to frostbite and deterioration of tropical fruits, which will affect the taste and nutritional value of fruits.
4. Green leafy vegetables should not be stored in the refrigerator.
Fresh vegetables are best eaten in time, and should not be refrigerated in the refrigerator. Generally, green leafy vegetables after refrigeration are easy to deteriorate and rot. . At the same time, in order to avoid the loss of moisture in the food placed in the refrigerator, it is better to wrap the food with a layer of plastic wrap, and then put it in the refrigerator to refrigerate.
5. The raw food and cooked food in the refrigerator cannot be mixed, and it is best to use plastic wrap to package, especially cooked food should be placed in a covered container, so as to avoid cross-infection between foods. The fruits, vegetables and raw food in the refrigerator should be rinsed with clean water, drained and then put in the refrigerator.
6. The food in the refrigerator should not be stored for a long time. Generally, the food in the refrigerator should not exceed three days in summer, and it is best not to eat the food after more than three days, so as to avoid problems such as food poisoning.
7. Regularly clean and disinfect the refrigerator. Due to the high temperature in summer, the mixing of food in the refrigerator can easily lead to the growth of bacteria. It is best to clean the refrigerator regularly. Can be scrubbed with 0.5% bleach. Pay special attention to scrubbing the box seams, corners, and shelves, and then wipe them with a clean damp cloth.
8. It is advisable to place raw meat products in the freezer. Generally, meaty foods need to be stored at low temperature. But for meat products that do not need to be frozen, they are generally placed in the upper layer of the refrigerator, while vegetables and fruits are placed in the middle layer, and other cooked products are placed in the middle layer of the refrigerator.
