1. The compressor
The quality of the compressor determines the wind speed inside the fridge, and refrigeration and freezing capacity. Some manufacturers of cheap commercial fridges use relatively cheap compressors to save money.
2. Internal structural decoration
There is also a difference in the manufacturing cost of the internal decoration of the fridge. Take the partition for an example, some partitions are made of glass, which is easy to clean, while others are made of plastic, which has a higher price than glass. If the internal floodlight adopts the LED light, it will have the advantages of high brightness, less power consumption, long service life, etc., but ordinary bulbs cannot achieve such a good use effect.
What you need to know is that the plastic prices of the fridge partition, drawer, and storage box are different. For example, the price of ABS plastic is 10 to 20 yuan per kilogram or so, while the price of common plastic is 10 yuan per kilogram or so. It's also important to be aware that if you're experiencing cheap commercial refrigeration, the internal structure you see when you open your fridge may also be made of cheap materials.
3. Materials used to make the appearance
There are differences in the panels of fridges such as the single door upright chiller, two-door fridges, 3 door undercounter freezer, and side-by-side combination fridges. For example, there are stainless steel wire drawing, ordinary metal, and high strength glass used to make the panels, in which ordinary metal panels are commonly used in cheap commercial fridges, while panels of stainless steel wire drawing and high strength glass are used for high-end fridges.
4. Application of technology
At present, more and more technologies are adopted in fridges worth thousands of yuan, such as the device for odor cleaning and freshness preservation, which can absorb and remove the odor in the fridge; Touch screen management have functions such as reminding us of expired ingredients; The application of the frequency conversion or the fixed frequency, also plays an important role in deciding the temperature inside fridges, preservation effect, noise intensity and so on.
Small fridges or cheap commercial fridges do not come with these features, which have only the function of freezing or refrigeration. Even if low-end fridges have these features, the choices are different. For example, the display screens on the fridge include the touch computer display screen and the touch-tone electronic display screen. Even the most simple doorknob, also can be made from different materials such as stainless steel and aluminum alloy.
