Maintenance methods for horizontal refrigerators and kitchen freezers

　　1. Maintenance method of horizontal refrigerator
　　First, if there are not many items to be stored, you can place a slightly larger beverage bottle containing salt water in the horizontal refrigerator or kitchen freezer, so that the internal temperature difference of the cabinet can be balanced, thereby reducing the number of compressor start-ups and prolonging The service life of the compressor.
　　Second, if horizontal refrigerators and kitchen freezers are open, electric fans and air conditioners should be avoided. The night curtain should be closed during non-business hours.
　　Third, if the condensers of horizontal refrigerators and kitchen freezers are finned, they should be cleaned with a brush every one month or so to improve the heat dissipation effect.
　　Fourth, the condensers of horizontal refrigerators and kitchen freezers are generally under the steel plate of the cabinet, so horizontal refrigerators and kitchen freezers should be placed in a well-ventilated place, and the horizontal refrigerators and kitchen freezers should be wiped off in time. The dust on the outside of the body can improve the condensing effect of the condenser so as to achieve the purpose of improving the cooling effect and saving electricity. After the horizontal refrigerators and kitchen freezers have been used for a long time, the inner tanks of the horizontal refrigerators and kitchen freezers are prone to frost. It is necessary to defrost the horizontal refrigerators and kitchen freezers frequently (about seven days) to improve the cooling effect. These are the main maintenance methods for horizontal refrigerators.

Second, the maintenance of the freezer
　　In cold weather, there are relatively few opportunities to use electric freezers in both the home and the cold drink department, and the refrigerant may freeze if it is stopped for a long time, which will cause the flow path to be unsmooth and affect the service life of the machine. The practice is not worth advocating, but the downtime is not a big problem. The important thing is to master the skills. The electric freezer that is disabled in cold weather should be energized 1-2 times a month at least to allow the refrigerator to run for 10 minutes. At the same time, it must be thoroughly maintained during the first shutdown. Freezer condensers and compressors are mostly exposed to the outside, and they are easily stained with dust and spider webs. Use a soft brush to remove them. Do not flush with water when cleaning the condenser and compressor, so as not to reduce the insulation performance of the electrical appliance. When cleaning the inner wall, all items and parts should be taken out, and a thorough cleaning should be carried out. At the same time, the door seal should be wiped clean, and a proper amount of talcum powder should be applied to avoid seal adhesion. If there are still peculiar smells inside after cleaning, use baking soda with a concentration of 3% to carefully scrub the inner wall of the storage room, so that the peculiar smell can be removed quickly. In addition, it should be noted that, do not forcibly cut off the power supply of the refrigerator. If the power supply is forcibly cut off and the power supply is turned on immediately when the refrigerant has a fairly high pressure, the high pressure causes the motor to be overloaded. At this time, the starting current is about 20-30 times the normal value, and it is easy to burn the motor. Therefore, when the electric freezer is disabled, the temperature in the refrigerator should drop to a certain value, and the power plug can be unplugged after the thermostat automatically cuts off the power. When the freezer is not in use, pay attention to the maintenance of the freezer.
