First, choose the compressor brand is not sloppy, it is the heart. The size of the compressor and its power determine the power consumption, working time and cooling effect of the freezer. If the compressor is too small, the freezer will not stop for a long time, and if it is too large, it will cause a waste of resources. The volume of the freezer should match the compressor of the applicable size.
Second, the evaporator / condenser and other components are also important components of the freezer. The evaporator tube area of the hair generator is large, the density is high, the heat absorption area is large, and the cooling capacity is strong.

3. Insulation materials. The freezer thickened cabinet body and polyurethane overall foam insulation effect is good, can reduce the loss of the compressor.
4. Hermeticity: the sealing performance of the freezer door and whether the door material is good or not easy to deform, is also the key to the quality of the freezer.
