Features of high-quality fresh-keeping cabinet:
1, the effective volume of the fruit fresh-keeping cabinet is larger.
The marks of the technical parameters of high-quality fresh-keeping cabinets are all in accordance with the requirements of international standards, and all of them have passed the sampling inspection by the national quality and technical supervision institutions for many times over the years.
2. Service life of fruit fresh-keeping cabinet
From the structural point of view, there is no integral steel frame in the fresh-keeping cabinet of inferior and low-priced supermarkets. A six-door cabinet is a combination of a two-door cabinet and a four-door cabinet. The door frame is assembled after the cabinet is foamed, so it is difficult for such a fresh-keeping cabinet to withstand multiple moves. The door frame will fall off in a few years and it is difficult to repair. From the material point of view, inferior low-cost fresh-keeping cabinets and supermarket fresh-keeping cabinets are made of cheap materials. Stainless steel is replaced by stainless iron or aluminum plate, copper tube is changed into aluminum tube or composite steel tube, and ABS engineering plastic is changed into ordinary plastic. It is reasonable to shorten the performance and service life of the fresh-keeping cabinet after the material is so thick and thin that copper becomes iron. In particular, it is necessary to point out that the built-in evaporation tube of inferior low-cost fresh-keeping cabinets and supermarket fresh-keeping cabinets is obviously coated with a layer of copper on the surface of composite pipes (that is, steel pipes), but they dare to say that they are also made of copper pipes. The compressor used in low-priced cabinets is a household type with low starting torque, which is not suitable for the requirements of frequent door opening and frequent starting of commercial fresh-keeping cabinets. The compressor needs to be started repeatedly before it can run. Because of the low power of domestic compressor, the fresh-keeping cabinet will run all day in high temperature season, and the compressor will lose a lot. The manufacturer's practice of replacing commercial compressors with domestic ones has greatly damaged the interests of customers.
3, fruit fresh-keeping cabinet electricity expenditure
Although the inferior supermarket fresh-keeping cabinets saved some money when they were purchased, they kept spending more money in their long-term use. First of all, because the fresh-keeping cabinet is used continuously for many years, the electricity bill is not a small sum. The power consumption is mainly reflected in the heat preservation performance in terms of the performance of the fresh-keeping cabinet. In order to achieve good thermal insulation performance, we should not only ensure the thickness of the insulation layer, but also reduce the thermal conductivity of the insulation layer. Only the high-pressure foaming machine with high control precision can meet this requirement. Because the high-pressure foaming machine and high-pressure foaming fixture have large investment and complex technical requirements, manufacturers of low-cost fresh-keeping cabinets all make free foam by hand, and the thermal conductivity of insulation layer is much larger than that of high-pressure insulation layer. To make matters worse, these low-priced fresh-keeping cabinets filled bricks, stones and a lot of waste hard foam before foaming, and then poured a layer of foaming material on the surface to deceive consumers. How much insulation effect can this insulation layer have? Using such a supermarket fresh-keeping cabinet means that it consumes 2-3 kWh more electricity every day than a high-quality fresh-keeping cabinet with the same cabinet temperature, and the difference will be consumed in 2-4 years, and then the more it is used, the more it will be lost. If we calculate the volume shrinkage account, the service life shortening account and the repair expense account, wouldn't the cost of buying these inferior low-priced cabinets be higher?
