The volume of 102 refers to 102 liters (the unit symbol for liters is L), which means that 102 liters of water can be placed. The density of water is 1kg/liter, which is 102kg of water. The density of conventional pork is smaller than that of water. The density of general pork is about 0.975g/cm3, which means that 99.45 kilograms of pork can be placed. Of course, the actual density must be less, because there cannot be no gaps.

The structure of the freezer

The structure of the freezer is the same as that of the refrigerator. The freezer consists of three parts: the box, the refrigeration system, and the temperature control device.

1. Composition of the box:

The basic function of the outer casing is lined with thermal insulation layer and the countertop box is thermal insulation. The quality of the thermal insulation performance is directly related to the thermal insulation performance of the box.

2． Refrigeration system:

The refrigerator refrigeration system mainly consists of four parts: compressor, condenser, evaporator and capillary tube, forming a closed cycle system. The evaporator is installed above the inside of the refrigerator, and other components are installed at the back of the refrigerator. The system is filled with a substance called "Freon 12 (CF2Cl2, international symbol R12)" as the refrigerant.

3． Temperature control device:

The temperature control device of the refrigerator is called a temperature controller. Its main function is to turn on the compressor when the temperature in the box is too high, so that the refrigeration system can work, thereby lowering the box temperature; when the box temperature drops to the required temperature, the compressor is powered off.
