Supermarket refrigerated showcase maintenance skills
1, supermarket refrigerated showcase peculiar smell
supermarket refrigerated showcase sometimes also produces peculiar smell mainly from the defrosting and freezing of the freezer. The peculiar smell from the refrigerator can be directly put into deodorant or electronic deodorizer to eliminate it. It can also be shut down to clean the refrigerator compartment thoroughly. For the peculiar smell in the freezer compartment, cut off the power supply, open the door, defrost and clean it, and remove it with a deodorant or electronic deodorizer. If there is no deodorant, etc., you can scrub the inner tank and accessories of the supermarket refrigerated showcase, put in half a cup of liquor (preferably iodine), close the door, and no power supply. After 24 hours, the peculiar smell can be eliminated. It is a poor conductor, and the conductivity is 1/350 of aluminum. The frost covers the surface of the evaporator and becomes a heat insulation layer between the evaporator and the food in the box. It affects the heat exchange between the evaporator and the food in the box and makes the temperature inside the box. If it cannot be lowered, it will reduce the refrigeration performance of the supermarket refrigerated showcase, increase the power consumption, and even cause the compressor to generate heat due to long-term operation, which will easily burn the compressor. In addition, there are various food odors in the frost, and if the frost is not defrosted for a long time, the refrigerator will emit a peculiar smell. Under normal circumstances, when the frost layer is 5mm thick, it is necessary to defrost.
2, supermarket refrigerated showcase temperature influence
The power consumption of supermarket refrigerated showcase is divided into rated power consumption and actual power consumption. The rated power consumption is when the ambient temperature is 25℃, the supermarket refrigerated showcase is in a stable operation state (the average temperature of the refrigerator is 5℃, the maximum temperature of the freezer is -18℃), and the power consumed for 24H operation. The actual power consumption refers to the electrical energy consumed by the refrigerator in actual use. The actual power consumption of supermarket refrigerated showcase is sometimes higher than the rated power consumption, and sometimes lower than the rated power consumption. The actual power consumption varies with the supermarket refrigerated showcase environment, how much food is stored, the control temperature in the box and the number of times the door is opened Depending on the length of time, the higher the ambient temperature, the more food is stored, the lower the temperature controlled in the box, the more times the door is opened, and the longer each time the door is opened, the greater the power consumption of the supermarket refrigerated showcase. Conversely, the lower the power consumption.
1, the increase in ambient temperature will bring superThe market refrigerated showcase has slower heat dissipation and slower temperature drop inside the box, which leads to longer boot time and increased power consumption.
2. The ambient temperature rises. Due to the large temperature difference between the inside and outside of the supermarket refrigerated showcase, the heat dissipation speed of the insulation layer of the cabinet will also increase, which will cause more cooling loss, resulting in shorter downtime, longer response time and longer power consumption. Big.
3. For ordinary supermarket refrigerated showcase, according to the experimental data analysis, when the ambient temperature reaches 32℃, the power consumption is about 2 times that at 25℃, and the power consumption at 30℃ is about 1.6-1.8 times that at 25℃.
People who use the supermarket refrigerated showcase have this feeling. Opening the door of the supermarket refrigerated showcase can feel the air-conditioning running out, and running the air-conditioning will inevitably cause the temperature inside the box to rise, which will cause the thermostat to delay the shutdown The temperature causes the compressor to work for a long time and the power consumption increases.
refrigerated showcase supermarket refrigerated showcase tells you that supermarket refrigerated showcase also needs to be taken care of in order to be more useful.
