Exclusive Secret: What factors affect refrigerator power consumption?

Refrigerator, commonly known as “electric tiger”, has always been a large household appliance consumer. In recent years, the country has called for energy-saving and emission reduction. Many refrigerator manufacturers also strive to reduce power consumption, and even 0.01 degrees can become myths in the industry. In fact, as long as you pay attention to details of some daily life, you can reduce the power consumption of the refrigerator. Today, Xiao Bian gives you a method to reduce power consumption. Let's take a look.

1, the ambient temperature can not be overheated. The ambient temperature has a direct influence on the power consumption of the refrigerator. When the ambient temperature rises, the heat dissipation of the refrigerator will slow down, and the slow down of the temperature in the cabinet will cause the boot time to increase and the power consumption to increase. Take the experimental data analysis of the ordinary refrigerator, when the ambient temperature reaches 32 °C, the power consumption is about twice at 25 °C, 30 °C power consumption is 25 times of 1.6 ~ 1.8 times. Therefore, the refrigerator should be placed as far away from the heat source as possible, with good ventilation and shade.

2, thermostat file often adjust. Each refrigerator has a thermostat that adjusts the temperature in the refrigerator by adjusting the gear. The higher the thermostat, the lower the temperature in the refrigerator. When the freezer reaches -18°C, it is difficult to lower every 1°C. The colder it is more difficult to reduce, but the minimum temperature for continuous operation can reach -24°C. At this time, the temperature difference between the inside and outside and the amount of coldness will be lost. And there is a long boot time or even no shutdown.

If the boot time is too long due to the high gear, you may wish to lower the thermostat gear and the boot time will be significantly shortened. If the freezer compartment is replaced with -18°C instead of -22°C, it can save 30% power consumption.

3, open the door to minimize the number. Open the door of the refrigerator can feel cold air running out, and the cold running away will inevitably cause the temperature inside the refrigerator to rise, it will cause the temperature controller delay can not reach the shutdown temperature and cause the compressor to work for a long time, the power consumption increases .

4, timely defrosting is very important. Frost is a poor conductor of heat, covering the surface of the evaporator and becoming a thermal insulation layer between the evaporator and the food inside the box, affecting the heat exchange between the evaporator and the food in the box, so that the temperature in the box does not fall, and the refrigerator is lowered. The cooling performance increases the power consumption, and even causes the compressor to run for a long time and generate heat and burn out. In addition, the smell of various foods is stored in the cream, and defrosting for a long time will make the refrigerator smell bad. In general, when the frost layer is 5 mm thick, it should be removed.
