The correct way to adjust the temperature of commercial refrigerators
The principle of commercial refrigerators is that the compressor produces a series of physical changes by compressing the refrigerant to achieve the cooling effect, but it It is also highly susceptible to the influence of the external environment, especially in seasons with large temperature changes, such as summer and winter. At this time, we need to adjust its temperature to make it work properly.
1. Temperature adjustment in winter
Our refrigeration effect is generally required to be controlled between 0-10 degrees, but generally in winter, because the temperature Lower, so that refrigeration can easily reach the set temperature. Therefore, we generally need to adjust the temperature to 4 or more. Generally, when the ambient temperature is lower than 16 degrees, we can adjust the cabinet temperature to 5th gear. If the ambient temperature is lower than 10 degrees, it is even more necessary to increase it, and it can be adjusted to 6-7 gears, which can also save electricity and facilitate cooling.
2. SummerTemperature adjustment
And when the ambient temperature is very high in summer, our commercial freezer It’s going to be tough as the internal temperature drops, and the boot time becomes longer and the compressor is overworked. At this time, we need to adjust its temperature again, and adjust the temperature to 2-3 files. Our compressors don’t need to work so hard, and they won’t be damaged so easily, so it can save energy and prolong its life.
3.Cooling effect
Of course it is one thing to adjust the temperature according to the season, but there is still a certain deviation in the temperature Yes, which requires us to check whether the cooling effect is sufficient. If it is considered from the perspective of commercial refrigerators, it is not appropriate, because there are still foods that need to be refrigerated in the cabinets. Therefore, after we adjust the temperature, we also need to check whether the cabinet food is refrigerated during operation for a period of time to prevent spoilage.
Therefore, everyone should adjust the temperature to the best state in different seasons in the correct way, which can not only save energy and electricity, but also better protect the commercial freezer. It can also prolong its service life, which is very worthy of everyone’s attention.
Maintenance method of commercial freezer
1. Determined according to the volume of the freezer
If storage There are not many items, and a slightly larger beverage bottle containing salt water can be placed outside the horizontal freezer or kitchen freezer, so as to balance the temperature difference outside the cabinet, thereby increasing the number of compressors on and off, and extending the service life of the compressor.
2. Place it in a ventilated position to keep it clean
The condensers of the freezer and kitchen freezer are generally on the steel plate of the cabinet, so the refrigerator, kitchen The freezer should be placed in a well-ventilated position, and the dust in the horizontal freezer and the kitchen freezer should be wiped off in time, so that the condensation effect of the condenser can be improved to achieve the purpose of improving the cooling effect and saving electricity.
3. Frequent defrosting
After the refrigerator and kitchen freezer have been used for a long time, the refrigerator and kitchen freezer The inner liner is easy to frost, so it is necessary to defrost the refrigerator and kitchen freezer frequently (usually about seven days) to improve the cooling effect.
4, prevent electric fans, air conditionersdirect blowing
If the freezer and kitchen freezer are open, the electric fan and air conditioner should be prevented from blowing directly, and the night curtain should be closed during non-business hours.
5, cleaningfinned condenser
The fin type of the condenser should be cleaned with a brush every other month or so to improve the heat dissipation effect.
