First, there is less air-conditioning. The matched unit power is about 30% to 40% less. Usually, a 1.0 cubic home chest freezer matches with a 1/2HP compressor, but the compressor installed in a low-cost home chest freezer is 1/3 or 3/8HP.

　　Second, the cooling temperature is high. The working temperature is marked confusingly, sometimes marked as 0 degrees. The user reflects the summer freezing room temperature between 8 degrees and 12 degrees. This brings safety risks to food preservation that requires a constant low-temperature environment.

　　The third cooling rate is slow.

　　The low-cost home chest freezer's compressor has low power, which is suitable for the reduction of the condenser area, condenser fan power and air volume, and evaporator area of ​​the system. Less refrigeration, slow refrigeration, only used in winter, spring, autumn, or only used in the northern region, means that it can be roughly coped with. On the contrary, this home chest freezer has a high temperature during the day or night in summer or contains a lot of food, the food turnover is large, and the temperature of the home chest freezer is low, the hygiene and safety of stored food cannot be guaranteed.

　　The above is related to performance. Is there anything else in the performance of the bad home chest freezer? Of course, there are, such as service life and later expenditures.

　　Home chest freezer life: low-priced home chest freezer with poor structure does not have any steel frame. The door frame is assembled after the cabinet body is foamed. This home chest freezer is difficult to move multiple times. The door frame will fall off within a few years and is difficult to repair. Low-quality low-cost home chest freezer cabinet body selection in terms of material. If the material is cheap, replace it with stainless steel or aluminum plate, replace the copper pipe with an aluminum pipe or composite steel pipe, and replace ABS engineering plastic with ordinary plastic. After the material of the home chest freezer becomes thicker and thinner, and the copper becomes iron, the performance and service life are also reasonable.

　　Expenses after use: I saved a little when I didn't buy the home chest freezer but continued to spend more money when I used it for many years. First of all, because the home chest freezer has been used continuously for many years, the electricity bill is high. The power consumption is mainly reflected in the heat preservation performance of the home chest freezer.
