1. Select the refrigerator according to the need of the refrigerator. According to the cooling method, the refrigerator can be divided into a direct cooling refrigerator and a frost-free refrigerator. Direct cold refrigerator has simple structure, convenient operation, refrigerator fresh-keeping, good moisturizing performance, relatively cheap price, but manual defrosting after frosting; frost-free refrigerator cools quickly, can automatically defrost after frosting in the refrigerator, the temperature inside the box More uniform, but the power consumption, food consumption and noise are relatively large compared to the direct cooling of the refrigerator. 2. Try to choose the refrigerator with double temperature control and multi-temperature control as the temperature control form. The refrigerator can be divided into single temperature control, double temperature control and multi-temperature control. The single temperature control structure is simple and inexpensive, but sharing two thermostats in two or three compartments results in inaccurate indoor temperature control. Dual temperature control and multi-temperature control temperature control equipment can control the temperature of different compartments as needed. At present, the dual temperature control and multi-temperature control products have more electronic temperature control, which can display the temperature of each room and facilitate adjustment. 3. According to the number of family population, choose the refrigerator volume reasonably. The larger the volume, the better. The volume of the refrigerator is generally considered to be 40-60 liters per person. And with the improvement of living standards and the pace of life, when considering the overall storage of the refrigerator, the refrigerator with a larger freezer should be selected appropriately. In addition, large-capacity refrigerators take up a lot of space and consume more power. Therefore, when choosing, you must start from your own actual situation. Households with small populations can choose traditional double-door refrigerators, and the rooms are large in area and relatively populous. The family can choose between a three-door refrigerator or a door-to-door refrigerator. Don't blindly pursue large capacity and waste. In addition, when consumers purchase refrigerators, they should also pay attention to whether the energy-saving of refrigerators is a concept opposite to the refrigeration capacity of refrigerators. Consumers should consider them comprehensively when purchasing, and try to choose them when they meet basic needs such as volume and function. A product with high energy efficiency and low noise. (Yu Chen) Ethylene propylene rubber O-ring is formed by copolymerization of ethylene and propylene. The main chain is not double chain, so the heat resistance, aging resistance, ozone resistance and stability are excellent, but sulfur can not be added. Because sulfur cannot be added, it is generally not used for food or exposed to aromatic hydrogen. It is basically used as a seal in the brake and radiator of the automobile water tank.
