With the development of supermarket convenience stores, refrigerators in supermarket convenience stores are almost the standard electrical appliances in supermarket convenience stores. However, because the refrigerators of supermarket convenience stores have been maintained at a low temperature, the power consumption has been high, so the energy saving of refrigerators in supermarket convenience stores has become a topic of increasing concern. Why does the refrigerator in the supermarket convenience store consume so much electricity?
With the development of supermarket convenience stores, refrigerators in supermarket convenience stores are almost the standard electrical appliances in supermarket convenience stores. However, because the refrigerators of supermarket convenience stores have been maintained at a low temperature, the power consumption has been high, so the energy saving of refrigerators in supermarket convenience stores has become a topic of increasing concern. Why does the refrigerator in the supermarket convenience store consume so much electricity?
Of course, we can't ignore the fact that the refrigerators in supermarkets and convenience stores are power-consuming appliances. In addition to our own reasons, how can we reduce power consumption from use? Below we analyze from four aspects.
1. Reduce the power consumption of refrigerators in supermarkets and convenience stores, and the room temperature cannot exceed the standard
The indoor temperature will affect the cooling effect of the beverage cabinet in the convenience store to a certain extent. The place where the temperature changes greatly will increase the failure rate of accessories. The outer frame of the glass door display cabinet is prone to fog and water, which affects the cooling effect. The ambient temperature in the store should be kept as stable as possible to reduce the workload of the compressor. The ambient temperature has a direct impact on the power consumption of the refrigerator. If the ambient temperature rises, the heat dissipation of the freezer will slow down, and the slow drop in the temperature inside the box will lead to a longer boot time and an increase in power consumption. According to the experimental data analysis of ordinary refrigerators, when the ambient temperature reaches 32 °C, the power consumption is about twice that of 25 °C, and the power consumption at 30 °C is 1.6 to 1.8 times that of 25 °C. Therefore, the freezer should be placed as far away from the heat source as possible, preferably in a ventilated and shaded place. Therefore, the beverage cabinet should be placed on the backlit surface as much as possible, and the shading equipment should be added without affecting the convenience store business.
2. Reduce the power consumption of refrigerators in supermarkets and convenience stores, and the refrigerators should be set to a reasonable temperature
Each freezer has a thermostat, which adjusts the temperature in the refrigerator by adjusting the gear. The higher the gear of the thermostat, the lower the temperature in the freezer. After the freezer reaches -18 °C, it is difficult to drop every 1 °C, and the colder it is, the more difficult it is to drop, but the lowest temperature in continuous operation can reach below -24 °C, and at this time, it will also be due to the large temperature difference between the inside and outside, and the loss of cooling capacity. However, the startup time is very long or even does not stop. This kind of thermostat is only for household refrigerators, and the thermostats used in commercial refrigerators and convenience store refrigerators are all accurate microcomputer control cabinets to display cabinet temperature, the error is smaller, and the temperature in the cabinet is clear at a glance. When the convenience store series refrigerators leave the factory They are all set to stop at 3 degrees and start at 8 degrees, but there must be a temperature difference in the middle. When the weather is hot, the temperature sometimes rises to 11-12 degrees, which is also normal.
3. Reduce the power consumption of refrigerators in supermarkets and convenience stores, and avoid repeatedly opening and stopping beverage cabinets
Repeated start and stop will affect the life of the beverage cabinet. During the process of repeated start and stop, the workload of the compressor will be increased, which will greatly increase the power consumption. When the beverage cabinet in use does not completely need to be closed, try not to close the beverage cabinet in the convenience store. In order to ensure energy saving, you can also operate the temperature according to the manufacturer's instructions.
Fourth, reduce the power consumption of refrigerators in supermarkets and convenience stores, and minimize the number of times the refrigerators are opened.
When you open the door of the beverage cabinet, you can feel the air-conditioning running out, and the running away of the air-conditioning will inevitably cause the temperature in the freezer to rise, which will cause the thermostat to fail to reach the shutdown temperature and cause the compressor to work for a long time and increase power consumption.
