The refrigerator refers to a mechanical apparatus for changing the pressure change of the refrigerant gas by a compressor to achieve a low temperature refrigeration. The compressor used is different from the general air compressor due to the different conditions and compressed working media. According to the difference in the structure and working principle of the refrigerator, it is similar to the air compressor, and can also be divided into several different forms such as piston type, screw type, centrifugal type. Freezer is one of the most important components in compressed refrigeration equipment. The freezer is formed by the 50 parts of the compressor, condenser, evaporator, drying filter, and expansive throttle. Inside the injective amount of refrigerant is controlled by the electrical device according to the environment needs to achieve refrigeration heat transfer. the goal of.

The freezer is formed by the 50 parts of the compressor, condenser, evaporator, drying filter, and expansive throttle. Inside the injective amount of refrigerant is controlled by the electrical device according to the environment needs to achieve refrigeration heat transfer. Objective .

compressor

The low-pressure gas is increased to a high pressure. It is the heart of the refrigeration system, which is sucks low temperature and low pressure refrigerant gas from the suction tube. After the motor is operated by the motor, the high-temperature high pressure refrigerant gas is discharged to the exhaust pipe, which provides power to the refrigeration cycle, thereby achieving Compression → Condensation → Expansion → Evaporation (heatup) refrigeration cycle.

Condenser

The high-temperature high-pressure refrigerant vapor discharged from the compressor is condensed by heat dissipation as a liquid refrigerant, and the heat absorbed from the evaporator is absorbed by the medium (atmosphere) around the condenser.

Evaporator

Liquid refrigerant is converted to a gaseous state here.

Dry filter

In the refrigeration system, the effect of drying the filter is to absorb moisture in the refrigeration system, and impurities in the blocking system make it impossible to pass, prevent ice blocked and dirty in the refrigeration system line. Since the system is the most easily clogged to the capillary (or expansion valve), the drying filter is typically mounted between the condenser and the capillary (or expansion valve).

Expansive throttle

The high-pressure liquid refrigerant from the reservoir dryer is reduced, adjusted and controlled into the liquid refrigerant in the evaporator, so that it adapts to the change of the refrigeration load, and it is possible to prevent the compressor from blowing a liquid shot and evaporator outlet vapor. Abnormal overheat.
