How to exclude inferior refrigeration products

How to exclude inferior refrigeration products

1. Function

　　A, low cooling power. The matched unit power is about 30% to 40% smaller. Generally, a 1.0 cubic four-door supermarket freezer matches a 1/2HP compact machine, while the compact machine equipped with a low-priced four-door supermarket freezer is 1/3 or 3/8HP.

　　 B, the refrigeration temperature is high. Its working temperature symbolizes chaos, and some scales are 0 degrees. According to user practice, the cabinet temperature in summer is about 8 degrees to 12 degrees. This brings safety hazards to food preservation that requires a stable low temperature environment.

　　C, slow cooling speed. Because the compressor power of these air curtain cabinets is small, the area of ​​the condenser, the power and air volume of the condenser fan, and the area of ​​the evaporator that match the system are reduced accordingly. That is to say, the cooling capacity is small, so the cooling speed is slow. Such air curtain cabinets and supermarket refrigerators may only be used in winter, spring, and autumn, or only used in the northern region. It can also be perfunctory. On the contrary, this kind of air curtain cabinet will not be able to drop the temperature of the freezer due to the high temperature during the day and night in summer, or because of the large amount of food loaded, and the cleanness and safety of the stored food cannot be guaranteed.

　　2, service life

　　 From the structural point of view, a six-door cabinet is composed of a two-door cabinet and a four-door cabinet. The door frame is assembled after the cabinet body is foamed. Such a refrigerator cannot withstand repeated moves. The door frame will fall within a few years and is difficult to correct. From the raw material point of view, inferior low-priced air curtain cabinets, supermarket freezer cabinets, use whatever materials are cheap, convert stainless steel to stainless iron or aluminum plate, copper pipes to aluminum pipes or composite steel pipes, and ABS engineering plastics. General plastic. After the raw materials of the freezer become thicker and thinner, and copper becomes iron, it is reasonable to shorten its function and service life. The special demand pointed out that the inferior low-priced air curtain cabinets and the built-in transpiration tube of the supermarket freezer are obviously coated with a layer of copper on the surface of the composite tube (ie steel tube), but they dare to say that the copper tube is also used. The compression machine used for low-cost cabinets is a household type with low power torque, which is not suitable for the needs of frequent door opening and frequent activation of commercial refrigerators. The compression machine needs to be activated repeatedly to work. Because the power of the household compressor is small, the refrigerator will work all day long when the temperature is high, and the loss of the compressor is great. The manufacturer's practice of replacing commercial compressors with home-based ones has greatly harmed the interests of customers.

　　3, operating expenses

Although can save some money when purchasing refrigerators in supermarkets, they continue to spend more money in perennial use. First of all, because of the continuous use of refrigerators year after year, the electricity bill is not a small amount. In terms of the function of the freezer, the power consumption is mainly reflected in the heat preservation function. To achieve a good insulation function, in addition to ensuring the thickness of the insulation layer, the thermal conductivity of the insulation layer must also be reduced. As long as the high-pressure foaming machine with high control precision is selected to meet this demand. Because the high-pressure foaming machine and the high-pressure foaming fixture have a large investment and the skill requirements are messy, the low-priced air curtain cabinet manufacturers are all crafted freely, and the thermal conductivity of the insulation layer is much larger than that of the high-pressure insulation layer. To make matters worse, these low-priced air curtain cabinets are filled with bricks, stones and a lot of waste rigid foam before foaming, and a layer of foaming material is poured on the outside to deceive consumers. How much insulation effect can such an insulation layer have? Using such a supermarket refrigerated cabinet means that it consumes 2-3 kilowatt-hours more electricity per day than an excellent freezer with the same cabinet temperature. The difference in purchase prices will be consumed in 2 to 4 years. The more you use it, the more you lose. . If the volume shrinkage account, the service life shorten the account, the repair cost account, etc. are all calculated, will the cost of buying these inferior and low-priced cabinets be higher?

　　 A high-quality refrigerator is the first choice. What is a defective refrigerator? Where does it show today?

　　 When purchasing ultra-market refrigerators, the first thing to consider is the function of the refrigerators. The function of the low price supermarket refrigerator, the specific table is now in three aspects:

　　 1. The cooling speed is slow. Because the compressor power of these low-priced supermarket refrigerated cabinets and air curtain cabinets is small, the condenser area, condenser fan power and air volume, and evaporator area that match the system are reduced accordingly. That is to say, the cooling capacity is small, so the cooling speed is slow. Such air curtain cabinets and supermarket refrigerators can only be used in winter, spring, and autumn, or only in the northern regions, and it can be perfunctory. On the other hand, this kind of air curtain cabinet will not be able to drop the temperature of the refrigerator due to the high temperature during the day and night in summer, or because of the large amount of food loaded, and the cleanness and safety of the stored food cannot be guaranteed;

　　2. High cooling temperature. Its working temperature symbolizes chaos, and some scales are 0 degrees. According to user practice, the cabinet temperature in summer is about 8 degrees to 12 degrees. This brings safety hazards to food preservation that requires a stable low temperature environment.

　　 3. The cooling power is small. The matched unit power is about 30% to 40% smaller. Generally, a 1.0 cubic four-door supermarket refrigerated cabinet is matched with a 1/2HP compaction machine, while the compaction machine equipped with a low-priced four-door supermarket refrigerated cabinet is 1/3 or 3/8HP.

　　4. From the structural point of view, the inferior low price supermarket refrigerated cabinet has no steel frame. A six-door cabinet is made up of a two-door cabinet and a four-door cabinet. The door frame is assembled after the cabinet body is foamed. Such a refrigerated cabinet cannot withstand repeated moves. The door frame will fall within a few years and is difficult to correct.

5. From the point of view of raw materials, the material of the inferior low-price supermarket refrigerated cabinet is the material that is cheap. Use it without converting stainless iron or aluminum plate, copper pipe to aluminum pipe or composite steel pipe, and ABS engineering plastic to general plastic. After the raw materials of the refrigerator are so thick and thin, and copper becomes iron, its function and service life will be shortened. The special demand pointed out that the inferior low-priced air curtain cabinets and the built-in transpiration tubes of supermarket refrigerated cabinets are clearly coated with a layer of copper on the outside of composite tubes (ie steel pipes), but they dare to say that they also use copper tubes. The compactor selected for low-priced cabinets is a household type with low torque, which is not suitable for the needs of frequent door opening and frequent activation of commercial refrigerated cabinets. The compactor needs to be activated repeatedly to work. Because the power of the household compressor is small, the refrigerator will work all day long when the temperature is high, and the loss of the compressor is great. The manufacturer's practice of replacing commercial compressors with home-based ones has greatly harmed the interests of customers. The refrigerators produced by okmarts.com are in the interests of our customers and are trusted refrigeration brands for customers.
